My grandmother made all her own soap all of her life. She enlisted me at eight years old to help. She made a year's worth of soap (laundry, bathing, and house cleaning) once a year. I have fond memories of grating soap for her laundry. A handful of salt made bar soap from her wood ash lye and tallow. I am now 65 and have rarely used commercial soap. I just made a year's worth of soap yesterday. Loved this video!!!
Until the 1950s, doctor's were still tasting people's urine in order to diagnose some conditions and very very resistant to all the upstarts making nice clean lab equipment as an alternative. My dad could tell you the concentration, to quite some accuracy, of several acids by the colour they turned his skin. This skills we have lost 😂

It's possible they came for the soapmaking, and were unaware of the practical archaeology basis of your channel. I'm just sorry you had to respond to them at all. Thank you for this episode.

Sure you can... but why would you risk lye burns when handing boiling hot lye when you could, oh I don't know, wear gloves and protect your eyes? It's possible to do both, you know. We used to mouth pipette too, but just because you can do that with benzene or a concentrated acid or base, doesn't mean you should. Wearing protective gear doesn't stop you from doing the techniques in the historical manner, if you so choose. Good grief.

Thank you Sally for this video. I have waited for it because I wanted to know how soap was made in the old days. Now I am wandering how people found out how to make soap?? - I have made cord from horseradish after watching one of your videos and I love to try some new (old) ways of making things.

Sally I really love how your videos never seem canned or prebaked. When your result is a surprise to you, it's a surprise to us too. :) It comes off as very natural and sincere. Thank you.
Fellow archeologist here. Another brilliant video! I always look forward to your new videos. I know I'm going to learn something new and relax at the same time!👏
My only comment is that at some point people had a pretty good idea of how much lye to use for how much tallow. My grandmother made soap each autumn in a huge cauldron - as a 6 yo I could step inside and crouch down, so yeah, it was big. She didn't have any books or written recipes as such. What she had was her own grandmother's pot as a measure: this many pots of lye to this many pots of fat. Yes, she would test it as she cooked it, but an experienced crafter wouldn't make too many adjustments. She also never made soft soap. All her soap was salted to harden and cured for about a month before use. About the use of historical methods : I would leave even the soft soap to cure a good long time before using it. For as long as it has moisture the unreacted lye and fats will continue to neutralize each other, although at a very slow pace since there's no stirring and the temp is too low.
This is great. I have a wood burning stove, so now I know what to do with the ash. I can heat and clean with no waste. I've been using ash to clean the glass of the stove so I'm truly grateful thanks
Ruth Goodman's book " A domestic Revolution" describes getting oily dirt out of clothes with straight wood ash lye, in medieval times. I wish I had a wood stove, too, so I could try it!
Sally I just want to say you’ve been such a huge inspiration to my interest in history. I’ve always been incredibly interested in just the daily lives of ancient people and how we started creating things and you actually encouraged me to get a history degree. I would have gone into something I hated if it wasn’t for you inspiring me and showing just how amazing these things are and how happy studying history makes me. So thank you for genuinely changing my life.
Good clean fun! Haha! This is brilliant though. Having just spent most of my week washing dishes as if it were 1924 (drain trouble and the plumber couldn't get here for AGES)... it was strangely nice to watch this video, and someone ELSE boiling huge pots of water! You are exceptionally patient! And I suppose back then folks didn't feel a need to hurry through anything. Such a simple process but with such great results, very cool!
I felt my great grandmothers would have laughed at my whining when our hot water heater went out and I had to heat the dish water on an electric stove! But all my friends tried to commiserate with my "sufferings". Funny!
@@MMacNicol We really get used to our modern comforts don't we! It's surprising to me how difficult it really is, to imagine what life was like before all the things I grew up with.
The salted soap looks a bit like a well-aged runny cheese in the end, which kinda-sorta makes me want to taste-test it myself. The Videos are wildy interesting, thank you, Sally!
Thanks for this video, Sally. Absolutely fascinating! I have been using traditional Black Soap from France for years so it is interesting the see the process behind it and it has whet my appetite to try this. (I already make basic soap using modern lye.) The time this process takes and folks' squeamishness about the 'zap test' made me think of something my mum always said when I was growing up: "we don't know we are born..." If households still had to go to such efforts to achieve a basic cleaning product, maybe we would really appreciate what a luxury soap and being able to keep things clean actually are.
This is so helpful. I've been stumbling through wood ash lye soap making for years. It's a winter pasttime for me. But I have rarely gotten good results because my methods are modified modern methods. Thank you for the advice!
Thank you! This is the first video giving a proper fat to lye ratio, and how to get to trace and what it looks like. I've made soap with commercial lye but wanted to try this method. I've read that shopkeepers would have a container of wood ash soap and to make it firm up for the customer they'd sprinkle salt on the top then scoop it off.
I really enjoyed this as a modern soap maker I tried this method with a dismal outcome. I found your 1st video and this 2nd one cleared the mystery for me. Tx ever so much.
I remember my mum made soap back in the 70s with caustic soda. lol I hated it. We used to use it in a soap shaker to do the dishes. The bubbles never lasted a whole wash. I just wanted to have soap like normal people in the street did. Now I feel the desire to make soap myself!
Best wood ash soap making tutorial I’ve seen! I admire your patience and sense of discovery and wonder. Thank you for a thorough narrative referencing details and nuances.
Your presentations are really fascinating! I love the respect that you have for both our forbearers and for us. Passing down this know-how feels like a celebration of life that echoes through time to me. Thank you!!
Hello Sally! Thanks for this precious research and experiment! Very well done I'm usually making liquid soap with pure store-bought Koh You are almost the only one making soap the way should be with Koh!! One useful thing to add ... When you get the paste you want to do a clarity test before using it. You dissolve a tiny bit of soap into pure water(distilled or rain) and you see if the solution is cloudy or clear... Normally we let the paste sit at warm spot for some days and it will continue to set Your lye is made with rainwater and it looks quite clear originally ... So you should have quite an accurate test!
People are to sensitive... what you do is your business... as people on TH-cam say, these videos are for entertainment purposes only... I certainly are entertained by the information on how people made soap without all the stupid government regulations of nonsense.... People, like yourself, doing this, for our entertainment, are not stupid.. well researched and knowledgeable.. I for one, is very grateful for your videos, which l have just discovered
Dripping aka tallow, and lard make great soap. Soap making can be incredibly involved, and using modern materials and colourants, you can make GORGEOUS bars, however, it’s very simple to make a simple soap with a few commonsense safety precautions. Mainly respect the lye, cos it’s dangerous. Having said that, “zap” testing IS a thing and was done for centuries(and yes I’ve DONE it…I’m still alive)……..today it’s anathema and folk make a big fuss about it, for good reason tbh. It’s takes that rare quality, common bloody sense, which appears to be in rather short supply, to not either poison yourself or burn your tongue. And tbh I wouldn’t do it with modern highly concentrated lye, which is an ENTIRELY different beast from home produced wood ash lye…….much MUCH stronger. The thing is , there are nuances to take into account when using things like home produced wood ash lye, and nuance seems to be something that is lost today. Oh, and btw, in HP (hot process)soap making, that boiling up is called “volcanoing” lol. It freaks beginners out 😂. The transparency you’re talking about is what we call the Vaseline stage, which is where the soap has “gelled” which is a pretty reliable sign it’s fully cooked. And yes we still add salt(sodium chloride) to soaps to assist with hardening.
This is very interesting.. l have a wood stove, so can collect the ask to make a natural lye.... and soap... much appreciated, and g'day from Australia
I was wondering if you'd ever get back to the ash lye soap. Not that it mattered too much if you did or didn't, life is busy and all your videos are worth waiting for. This has lead me to wonder if I can make soap out of the old Crisco that lurks (almost malevolently) in the back of my pantry... Might need to try it for science, it's a little too far gone for cooking anyway....
I wonder if you could boil-purify it before starting to get rid of some of the old smell? Or if it is even wise to do something like that? Now I wonder if you could use rancid/old fats to make soap?
@@jjudy5869 Like, it doesn't stink, but it's been there for so long... I've lived here for 20 years and I don't remember it ever NOT just being in the back of the cupboard... you'll go look for something else and find it instead and be like "Oh right. That exists."
Thanks for your advice, I now know with how much lye and fat to start. Do you know John Seymour? His books are pretty popular among all the Jacks and Sallys-of all-trades in Germany. He recommends how to make a simple Aerometer for measuring the appropriate strength of a lye. Attach a small stone to the end of a stick, make a saturated solution of table salt, throw the stick in. It will swimm upright, mark the surface of the solution with a notch on the stick. Put the stick into your lye. The notch should also meet the surface here. I have no experience with that but I think it's worth a try. Cheers!
I love this video. You've been methodical, patient, and thorough. You can absolutely do a few things to refine the process within historical norms. However, you have definitely explored the gradients on the way.
this is a delightful video, THANK YOU! and oooh, when you took the pot to the sink to add the water, it took me right back to my soapmaking days in the 90s. most of hte people i knew made cold process bc it's faster. but i'm disabled and have horribly sensitive skin, so i always made hot process. a little more time to cook it til it was soap meant easy clean up + happy skin! 😻😻😻
I have always found hot process soap - which I have made in my time - doesn't come out as well as CP, but it does have its uses, for instance in making salt scrub for people's hard skin, or if one has an urgent request for soap....
CP isn’t faster…..I can knock out a batch of HTHP(high temp hot process) in a comparable time to a batch of CP, and the curing time is much less for HP. It can be used right after cooking as it’s exhausted the lye. It’s best to give it some drying time to harden, but fresh HP won’t burn the skin like fresh CP can. And it’s possible to make fancy HP that’s just as pretty as CP bars, with swirls and pretty tops etc……it just takes a little planning and a good recipe to get the fluidity required. Most HP makers add yoghurt at the end of the cook to thin and loosen their batter.
Oh my goodness, I've just discovered and subscribed to your channel! It's my favourite now 😍 So many exciting videos, I'm thrilled to have found you. Thank you ♥️
Thank you for these videos!! This is something I’ve always wanted to try and seeing you do it has pushed me to make it happen! I’ve been on a quest to find historical evidence of soap making for my hobby.
Using vinegar helps to create additional chemical reactions. You're better off rinsing very well with running water. Also, you should use a spoon or at least more of a "mixing" motion as opposed to the "whisking". You were throwing drops of soap batter all over.
in the middle east it was common and still is, to make soup from olive oil. I tried once to do soap with local olive oil and it was great!! I really want to try this style of diy lye
The ONLY comprehensive thing I have found about pot ash Koh on the Internet..thank you..thank you...thank you... Your finger feels and taste test are freaking the way to go...I'd like.to say tho for those that can't tell the difference...run said finger under the faucet...
Suggestion, mix some pumice or ground nut hulls into your Soft Soap for use as a mechanics handwashing paste. Seems like it would be good for anything that needed heavy degreasing. Smudge it on and leave overnight, maybe rub it in a few times and rinse?
I already make a peppermint and pumice washball based on a Victorian recipe which is very popular with the blacksmiths in my circle! But yes, sand or sugar or pumice in soft soap is great for heavy cleaning.
7sing acid to neutralize alkali might sounds good on paper. But in reality, 8ts a terrible idea. Acid +alkali will produce exothermic reaction, that is it will generate heat. Heat that can be so hot it will burn you. To wash off alkali or any chemicals in general, just use water. Plain water. Use a lot of water. Water is good for washing stuff. Using water is standard procedure in any labs.
really cool watching you do this the old fashioned way. I've made soap before but I just bought lye from the store. I always wanted to try the traditional way but getting that much hardwood ash was difficult for me.
🤣that was like a friend of mine. I taught her to make caramel and she was all “but now I’ve ruined my pan”……yes she was talking about the sugar set on the pan…….”Le sigh”
i've been looking a lot into historical and evolution of haircare, mainly hairwashing/hair hygene strategies. I am under the impression that using plain soap (soft soap and castille soap tend to come the most recomended) became common practice around the mid-late victorian era into the edwardian era when soap, skincare and hygiene became industrialised and commercialised. Haircare in the 18th century works in a totally different way but the very few sources i found for before the common use of hair powdering tend to recommend monthly-weekly use of vine ash in water, i tend to put it aside as a disparity between what was written down and what people actually did, but come to think of it, they probably had much better litteracy of what lye is safe than we do today ad using a weak lye would work pretty well as a stripping agent in a context where other products would be less practical to use. When looking into what other cultures (mainly the diné people, historical han/chinese and the yao/red hmong women) traditionally do, haircare seems to work in a simiar way (hair tying and covering to prevent dirt and dust, frequent combing and rare use of a degreasing agent, mainly saponin heavy local plants with oiling as a styling and conditioning product). The fact i only see it being mentionned in the early 20th century (a belgian housekeeping manual from 1903 reprinted around 1919 mentions soap bark) makes me believe it was either not something that was worthy of mentioning earlier, not something that was done in europe before we took that up from other cultures or that we don't really have that many plants with the same properties... but the saponaria was use as a detergent in roman era but i havent seen it mentioned as a possibility for haircare purposes. Which makes the curiosity of ancient roman haircare even more baffling : i believe they didn't use lye based product because the alledged use of lime by gaulish people is regarded as different and striking, i guessed that hair combing would have been enough as it is quite similar to the oil scrapping they were famous for doing (and mosaic and statues don't really translate the greasiness of the hair the same way it's easy to see if hair was pomaded or powdered in the 17th - 19th century portraiture) but hair washing with water was part of their culture, if the mention i have found online is to be believed (still haven't found the source sadly, i'm grasping at straws) they had a ritual of washing the hair in a lake concecrated to diana on her special day in august. Soap would be adequate enough but it was really expensive to make so wouldn't have been able to everyone (so what did commonfolk do then) and it's terribly uncommon later on, wasn't seemed to be used regularly for anything outside of textile production so even if plausible it's a highly unsatisfactory option to me. Saponaria was common in laundering so i believe it would have been the easiest cleansing agent available to them , maybe is was ubiquitous enough to just not be mentioned in texts (i tried extracting saponin from nettles last august and it worked surprsingly well as a mild hair wash) but then why was lye preferred a millenium later? why was saponaria not more synonimous with cleanliness like lavender became? was it just easier further north to make our own lye? or maybe lye being more astringent required less frequent washing? i had in mind to give a shot at all of my hypotheses but life got in the way, i guess it's now time to resume
@@MMacNicol i didn't think of looking more into her work, her passion for the evolution of how we approach hygien really influenced my practice and i didn't think to look at what she has to say about it, thanks for the tip :)
1:22 "you'll be fine with glass" - l've read somewhere that lye may make glass weaker, making it easily breakable. Sorry, cannot give sources for that, because l cannot find it anymore. Usually in Finland, the lye has been first heated up, then lard and salt added. How it differs, whether you make lye+lard and lard+lye? And can you write this or other recipes on text document? Thanks in advance.
Could you give us an idea of the strength of these products relative to a modern usage? Like what volume would be used for a modern load of laundry or dish washup? Or is it similar cleaning strength to currently popular cleaning products?
Thank you Sally. In your first soap video you mentioned doing you were doing your PHD. How'd it go? I remember watching that video and being excited about what you'd have to say about the history/origin of soap. Many thanks for all the wonderful videos and information 😊
Perfect video for a stormy Texas morning! You may mention it in the video, but I'll ask just in case I miss it: are the wash balls safe for modern appliances, or strictly hand washing? How might I use it in a modern off-grid home with a bucket and plunger type of wash machine?
Washballs are best for washing hands or as a kitchen sink hand soap, the herbs and similar help make the soap go further and add fragrance and texture, but for laundry stick to plain soap
A question: What you have been doing is time-consuming and complex 'pot' chemistry. How did our ancestors get the time to experiment and feel their way from wood ashes and fat through to bar soap? And how did they know what they wanted to get to? What possessed the first person to think that by running water through wood ashes, they would get anything remotely useful? Why would they pour hot fat into it and keep heating it for hours?
@@SallyPointer Nope. Never heard of it. I'm a marine biologist and woodland manager who does a bit of green woodworking.... Thanks for letting me know, I'll go look.
It's quite simple to find out, even in our days. Have a campfire with your kids and clean your greasy pan afterwards with ashes from the fire and water. All three together make soap.
Hello! I have just recently found your channel as I am currently attempting to make my own soap from homemade wood ash lye (only I'm using coconut and olive oils instead of tallow) I haven't been successful yet - it's my third attempt - but I have hope since finding this video! I do have a question though - would you mind sharing the process you used to clarify the batch of lye you used in the demonstration with the egg? I have been trying to figure it out on my own so that I can eventually make a better quality "white" soap as opposed to the black soap that you get with the high tannin content of the wood ash lye on its own. Any help, advice or referrals you can share would be extremely helpful and I would be so grateful!
Clearer lye is partly choosing ashes with very little darker charcoal and debris left, but mostly filtering through something like gravel rather than wood which will leach tannins into the mix. Then time. My lye gets lighter with storage.
Thank you for this detailed video. Would love to try it out sometime 😊I was wondering if one could dehydrate either the lye solution or the oil-lye mix a bit to speed up the cooking process. Would it be safe ? I have a solar dehydrator .
I think it would have the opposite effect. If a batch gets 'stuck' the usual solution is to add more water then reheat, lye needs to be strong, but especially in the early stages too strong is weirdly counterproductive for this method. You can use reduced water ratios when using commercial NAOH or KOH though
Thank you very much for this tutorial. It makes me want to try it. You sad about washing fleeces with it. How does your wool turn out with it? I use french black soap with a pinch of dish soap, since the addition of soda dryed the wool out. Well I'm still looking for the right fleece washing method. Have you tried the suint fermentation method yet? If so, did you like the procede and the result of it? Thank you again for this great video and this pragmatic approach.
I like soft soap for wool prep, a little vinegar in the rinse water can be useful if you feel your water and soap combination is risking any residue, but I don't always do that
It's a general purpose soap,and if made well is mild enough for hair and body. This batch isn't my best ever so it will be used for laundry and textile processing.

I think spent lye is probably lacking in the chemicals we are after, so there's probably not much use in using it again. There are historical references for lye in other applications though, so possibly some uses there
You'll need to read up a bit on their saponification values to get an idea of how they will differ. I'm more familiar with shea as a minor proportion of a recipe rather than the sole ingredient

I am a pensionist and just playing, enjoying and learning a lot from youtube channels from people around the world. Have a nice trip to Italy
I've got a paper coming out soon on the first discovery of true soap, and I also did an EXARC podcast recently that talks about it
What part of the horseradish do you use?

Please share the paper @@SallyPointer
Sally I really love how your videos never seem canned or prebaked. When your result is a surprise to you, it's a surprise to us too. :) It comes off as very natural and sincere. Thank you.
Thank you Sally. Don’t listen to the haters. Your channel is amazing, I love learning from you
Fellow archeologist here. Another brilliant video! I always look forward to your new videos. I know I'm going to learn something new and relax at the same time!👏
My only comment is that at some point people had a pretty good idea of how much lye to use for how much tallow. My grandmother made soap each autumn in a huge cauldron - as a 6 yo I could step inside and crouch down, so yeah, it was big. She didn't have any books or written recipes as such. What she had was her own grandmother's pot as a measure: this many pots of lye to this many pots of fat.
Yes, she would test it as she cooked it, but an experienced crafter wouldn't make too many adjustments.
She also never made soft soap. All her soap was salted to harden and cured for about a month before use.
About the use of historical methods : I would leave even the soft soap to cure a good long time before using it. For as long as it has moisture the unreacted lye and fats will continue to neutralize each other, although at a very slow pace since there's no stirring and the temp is too low.
I watched 3 grandmas make soap for the village somewhere in the Caucasus using that method.
This is great. I have a wood burning stove, so now I know what to do with the ash. I can heat and clean with no waste. I've been using ash to clean the glass of the stove so I'm truly grateful thanks
ashes are useful in so many ways, the primitive technology youtube channel does some crazy things with it
Make sure you burn hardwoods then.
Ruth Goodman's book " A domestic Revolution" describes getting oily dirt out of clothes with straight wood ash lye, in medieval times. I wish I had a wood stove, too, so I could try it!
Sally I just want to say you’ve been such a huge inspiration to my interest in history. I’ve always been incredibly interested in just the daily lives of ancient people and how we started creating things and you actually encouraged me to get a history degree. I would have gone into something I hated if it wasn’t for you inspiring me and showing just how amazing these things are and how happy studying history makes me. So thank you for genuinely changing my life.
That is so lovely to hear, thank you!
Good clean fun! Haha! This is brilliant though. Having just spent most of my week washing dishes as if it were 1924 (drain trouble and the plumber couldn't get here for AGES)... it was strangely nice to watch this video, and someone ELSE boiling huge pots of water!
You are exceptionally patient! And I suppose back then folks didn't feel a need to hurry through anything. Such a simple process but with such great results, very cool!
I felt my great grandmothers would have laughed at my whining when our hot water heater went out and I had to heat the dish water on an electric stove! But all my friends tried to commiserate with my "sufferings". Funny!
@@MMacNicol We really get used to our modern comforts don't we! It's surprising to me how difficult it really is, to imagine what life was like before all the things I grew up with.
The salted soap looks a bit like a well-aged runny cheese in the end, which kinda-sorta makes me want to taste-test it myself.
The Videos are wildy interesting, thank you, Sally!
Thanks for this video, Sally. Absolutely fascinating! I have been using traditional Black Soap from France for years so it is interesting the see the process behind it and it has whet my appetite to try this. (I already make basic soap using modern lye.)
The time this process takes and folks' squeamishness about the 'zap test' made me think of something my mum always said when I was growing up: "we don't know we are born..." If households still had to go to such efforts to achieve a basic cleaning product, maybe we would really appreciate what a luxury soap and being able to keep things clean actually are.
The most thorough process of soap making I've seen so far. Very educational.

I am so glad I found your channel. This has been informative and looking through your videos, I can tell this channel is right up my alley. Good work!
This is so helpful. I've been stumbling through wood ash lye soap making for years. It's a winter pasttime for me. But I have rarely gotten good results because my methods are modified modern methods. Thank you for the advice!
What I think is fascinating is our ancestor not only discovered this type of alchemy but also made this over wood fires they knew a lot.
So fascinating to see the process and learn how people in the old days did things. Excellent video.
Thanks for this tutorial video. Greet from Slovakia. 😀🖖👍
Thank you so much!
Thank you! This is the first video giving a proper fat to lye ratio, and how to get to trace and what it looks like. I've made soap with commercial lye but wanted to try this method. I've read that shopkeepers would have a container of wood ash soap and to make it firm up for the customer they'd sprinkle salt on the top then scoop it off.
I'd love that reference if you have it, I haven't got that story amongst my current notes I don't think. What century does it date to?
@@SallyPointer Sorry, I don't recall where I read that. It referred to shops in the US in the 1800's.
Very interesting. I started making cold process soap so I could recognize the stages of making soap the old way.
I really enjoyed this as a modern soap maker I tried this method with a dismal outcome. I found your 1st video and this 2nd one cleared the mystery for me. Tx ever so much.
Whats really fascinating about this is that our ancestors were doing this sort of chemical works back then
Awesome, you washed away my total ignorance about making soap. Hope to try this someday just for the learning journey.
I remember my mum made soap back in the 70s with caustic soda. lol I hated it. We used to use it in a soap shaker to do the dishes. The bubbles never lasted a whole wash. I just wanted to have soap like normal people in the street did.
Now I feel the desire to make soap myself!
Best wood ash soap making tutorial I’ve seen! I admire your patience and sense of discovery and wonder. Thank you for a thorough narrative referencing details and nuances.
Thank you from the Andes in Peru. I will try this.
Your presentations are really fascinating! I love the respect that you have for both our forbearers and for us. Passing down this know-how feels like a celebration of life that echoes through time to me. Thank you!!
I've been waiting for part 2 for *ages!* Thank you for the update! ❤ 👍
Excellent demo! I loved your demo of the historic way that soapmakers judged the quality and progress of their batch of soap.
Hello Sally! Thanks for this precious research and experiment! Very well done
I'm usually making liquid soap with pure store-bought Koh
You are almost the only one making soap the way should be with Koh!!
One useful thing to add ... When you get the paste you want to do a clarity test before using it. You dissolve a tiny bit of soap into pure water(distilled or rain) and you see if the solution is cloudy or clear... Normally we let the paste sit at warm spot for some days and it will continue to set
Your lye is made with rainwater and it looks quite clear originally ... So you should have quite an accurate test!
Yay! The much-awaited soap follow-up! Thank you, Sally :-)
Really enjoyed your very informative videos! Also really appreciate that your videos are not over-rehearsed. Excellent sound quality too!
Insane that I’ve only just now found your channel. It’s a goldmine and this is one of many things I’ve wondered about before! Thank you
Lye is used to strip the seasoning off cast iron when restoring.
I'm addicted to your voice and your videos. You are a phenomenal teacher and storyteller 👏
People are to sensitive... what you do is your business... as people on TH-cam say, these videos are for entertainment purposes only... I certainly are entertained by the information on how people made soap without all the stupid government regulations of nonsense....
People, like yourself, doing this, for our entertainment, are not stupid.. well researched and knowledgeable.. I for one, is very grateful for your videos, which l have just discovered
Dripping aka tallow, and lard make great soap. Soap making can be incredibly involved, and using modern materials and colourants, you can make GORGEOUS bars, however, it’s very simple to make a simple soap with a few commonsense safety precautions. Mainly respect the lye, cos it’s dangerous.
Having said that, “zap” testing IS a thing and was done for centuries(and yes I’ve DONE it…I’m still alive)……..today it’s anathema and folk make a big fuss about it, for good reason tbh. It’s takes that rare quality, common bloody sense, which appears to be in rather short supply, to not either poison yourself or burn your tongue. And tbh I wouldn’t do it with modern highly concentrated lye, which is an ENTIRELY different beast from home produced wood ash lye…….much MUCH stronger. The thing is , there are nuances to take into account when using things like home produced wood ash lye, and nuance seems to be something that is lost today. Oh, and btw, in HP (hot process)soap making, that boiling up is called “volcanoing” lol. It freaks beginners out 😂. The transparency you’re talking about is what we call the Vaseline stage, which is where the soap has “gelled” which is a pretty reliable sign it’s fully cooked. And yes we still add salt(sodium chloride) to soaps to assist with hardening.
I've certainly used the Zap test when making HP soap.
@@AnnabelSmyth Same here. Even like 10 years ago people on soaping groups were still recommending the zap test.
This is very interesting.. l have a wood stove, so can collect the ask to make a natural lye.... and soap... much appreciated, and g'day from Australia
IT'S PART TWO!!!!!
Thanks Sally! I've been waiting for part 2.
I was wondering if you'd ever get back to the ash lye soap. Not that it mattered too much if you did or didn't, life is busy and all your videos are worth waiting for. This has lead me to wonder if I can make soap out of the old Crisco that lurks (almost malevolently) in the back of my pantry... Might need to try it for science, it's a little too far gone for cooking anyway....
I wonder if you could boil-purify it before starting to get rid of some of the old smell? Or if it is even wise to do something like that? Now I wonder if you could use rancid/old fats to make soap?
@@jjudy5869 Like, it doesn't stink, but it's been there for so long... I've lived here for 20 years and I don't remember it ever NOT just being in the back of the cupboard... you'll go look for something else and find it instead and be like "Oh right. That exists."
I too have the Cupboard Crisco, and want to know if I can put it to good use!
Thanks for your advice, I now know with how much lye and fat to start. Do you know John Seymour? His books are pretty popular among all the Jacks and Sallys-of all-trades in Germany. He recommends how to make a simple Aerometer for measuring the appropriate strength of a lye. Attach a small stone to the end of a stick, make a saturated solution of table salt, throw the stick in. It will swimm upright, mark the surface of the solution with a notch on the stick. Put the stick into your lye. The notch should also meet the surface here. I have no experience with that but I think it's worth a try. Cheers!
I love this video. You've been methodical, patient, and thorough. You can absolutely do a few things to refine the process within historical norms. However, you have definitely explored the gradients on the way.
This is very interesting! Thank you.
The filling-up up thing is kinda funny, as it really makes sense that whisking a warm liquid would make a good head of bubbles.
this is a delightful video, THANK YOU!
and oooh, when you took the pot to the sink to add the water, it took me right back to my soapmaking days in the 90s. most of hte people i knew made cold process bc it's faster.
but i'm disabled and have horribly sensitive skin, so i always made hot process. a little more time to cook it til it was soap meant easy clean up + happy skin! 😻😻😻
I have always found hot process soap - which I have made in my time - doesn't come out as well as CP, but it does have its uses, for instance in making salt scrub for people's hard skin, or if one has an urgent request for soap....
I'm a real fan of hot process, I like it much better than cold process even when I'm making modern siaps
CP isn’t faster…..I can knock out a batch of HTHP(high temp hot process) in a comparable time to a batch of CP, and the curing time is much less for HP. It can be used right after cooking as it’s exhausted the lye. It’s best to give it some drying time to harden, but fresh HP won’t burn the skin like fresh CP can. And it’s possible to make fancy HP that’s just as pretty as CP bars, with swirls and pretty tops etc……it just takes a little planning and a good recipe to get the fluidity required. Most HP makers add yoghurt at the end of the cook to thin and loosen their batter.
@@paulinemegson8519I do both but cream soap is my favorite, though it does take 3 months at least to be ready.
I'm fascinated with soap. All kinds. I have a huge container that I squirrel away. Lol. IDK why.
Thanks for your experimental results
The EXARC talk is excellent.
Using an acid (vinegar) on a chemical burn is not recommended ... it causes a secondary reaction, increasing heat and worsening the burn.
Oh my goodness, I've just discovered and subscribed to your channel! It's my favourite now 😍 So many exciting videos, I'm thrilled to have found you. Thank you ♥️
Thank you for these videos!! This is something I’ve always wanted to try and seeing you do it has pushed me to make it happen! I’ve been on a quest to find historical evidence of soap making for my hobby.
Thank you for teaching about the old ways!
Using vinegar helps to create additional chemical reactions. You're better off rinsing very well with running water.
Also, you should use a spoon or at least more of a "mixing" motion as opposed to the "whisking". You were throwing drops of soap batter all over.
I am sure she just whisked for the video purpose and I think for the demonstration it worked fine.
in the middle east it was common and still is, to make soup from olive oil. I tried once to do soap with local olive oil and it was great!!
I really want to try this style of diy lye
It is called castile soap and is lovely. I cure mine for a year and once found 5 year old soap I had forgotten about. Was the best!
Totally brilliant! I love seeing how this all came together ❤ Thank you!
Waiting for this video is one of the reasons I subscribed to you. Thank you for this video! Your channel has been quite a mental treat for me :)
Thanks for the Vid Sally , I've been waiting for part two 8)
Thank you for the great lesson. Just loved it!!!!
The ONLY comprehensive thing I have found about pot ash Koh on the Internet..thank you..thank you...thank you...
Your finger feels and taste test are freaking the way to go...I'd like.to say tho for those that can't tell the difference...run said finger under the faucet...
awesome. got to try it.
Suggestion, mix some pumice or ground nut hulls into your Soft Soap for use as a mechanics handwashing paste. Seems like it would be good for anything that needed heavy degreasing. Smudge it on and leave overnight, maybe rub it in a few times and rinse?
I already make a peppermint and pumice washball based on a Victorian recipe which is very popular with the blacksmiths in my circle! But yes, sand or sugar or pumice in soft soap is great for heavy cleaning.
Brilliant Sally! I love your methods
I like watching ur vids!
Awesome video! Thank you for sharing!
7sing acid to neutralize alkali might sounds good on paper. But in reality, 8ts a terrible idea.
Acid +alkali will produce exothermic reaction, that is it will generate heat. Heat that can be so hot it will burn you.
To wash off alkali or any chemicals in general, just use water. Plain water. Use a lot of water. Water is good for washing stuff.
Using water is standard procedure in any labs.
Really want to try this! Thanks for sharing
Fascinating! Thank you!
really cool watching you do this the old fashioned way. I've made soap before but I just bought lye from the store. I always wanted to try the traditional way but getting that much hardwood ash was difficult for me.
Thank You Sally.❤
Such a good video thankyou so much🌿
This was amazing and informative. Thank you.
I loved this video
Please make more soap videos
Brilliant
in soap making groups when i first started making soap one question kept coming up - how do you clean up afterward? - i would just shake my head.
🤣that was like a friend of mine. I taught her to make caramel and she was all “but now I’ve ruined my pan”……yes she was talking about the sugar set on the pan…….”Le sigh”
@@paulinemegson8519 i once heard that we only use 10% of our brain, im beginning to think that was generous
i've been looking a lot into historical and evolution of haircare, mainly hairwashing/hair hygene strategies. I am under the impression that using plain soap (soft soap and castille soap tend to come the most recomended) became common practice around the mid-late victorian era into the edwardian era when soap, skincare and hygiene became industrialised and commercialised. Haircare in the 18th century works in a totally different way but the very few sources i found for before the common use of hair powdering tend to recommend monthly-weekly use of vine ash in water, i tend to put it aside as a disparity between what was written down and what people actually did, but come to think of it, they probably had much better litteracy of what lye is safe than we do today ad using a weak lye would work pretty well as a stripping agent in a context where other products would be less practical to use.
When looking into what other cultures (mainly the diné people, historical han/chinese and the yao/red hmong women) traditionally do, haircare seems to work in a simiar way (hair tying and covering to prevent dirt and dust, frequent combing and rare use of a degreasing agent, mainly saponin heavy local plants with oiling as a styling and conditioning product). The fact i only see it being mentionned in the early 20th century (a belgian housekeeping manual from 1903 reprinted around 1919 mentions soap bark) makes me believe it was either not something that was worthy of mentioning earlier, not something that was done in europe before we took that up from other cultures or that we don't really have that many plants with the same properties... but the saponaria was use as a detergent in roman era but i havent seen it mentioned as a possibility for haircare purposes. Which makes the curiosity of ancient roman haircare even more baffling :
i believe they didn't use lye based product because the alledged use of lime by gaulish people is regarded as different and striking, i guessed that hair combing would have been enough as it is quite similar to the oil scrapping they were famous for doing (and mosaic and statues don't really translate the greasiness of the hair the same way it's easy to see if hair was pomaded or powdered in the 17th - 19th century portraiture) but hair washing with water was part of their culture, if the mention i have found online is to be believed (still haven't found the source sadly, i'm grasping at straws) they had a ritual of washing the hair in a lake concecrated to diana on her special day in august. Soap would be adequate enough but it was really expensive to make so wouldn't have been able to everyone (so what did commonfolk do then) and it's terribly uncommon later on, wasn't seemed to be used regularly for anything outside of textile production so even if plausible it's a highly unsatisfactory option to me. Saponaria was common in laundering so i believe it would have been the easiest cleansing agent available to them , maybe is was ubiquitous enough to just not be mentioned in texts (i tried extracting saponin from nettles last august and it worked surprsingly well as a mild hair wash) but then why was lye preferred a millenium later? why was saponaria not more synonimous with cleanliness like lavender became? was it just easier further north to make our own lye? or maybe lye being more astringent required less frequent washing? i had in mind to give a shot at all of my hypotheses but life got in the way, i guess it's now time to resume
You might want to read Ruth Goodman's book "A Domestic Revolution" for historical data on these points.She covers it all.
@@MMacNicol i didn't think of looking more into her work, her passion for the evolution of how we approach hygien really influenced my practice and i didn't think to look at what she has to say about it, thanks for the tip :)
@@TheGabygael You're very welcome! This is all so cool.
1:22 "you'll be fine with glass" - l've read somewhere that lye may make glass weaker, making it easily breakable. Sorry, cannot give sources for that, because l cannot find it anymore.
Usually in Finland, the lye has been first heated up, then lard and salt added. How it differs, whether you make lye+lard and lard+lye?
And can you write this or other recipes on text document? Thanks in advance.
Nice
It's truly an art :)
The book is called what now 😅😅😅 I swear I'm an adult but some of these words from the olden tymes. 🤣🤣
YAY 🎉
Could you give us an idea of the strength of these products relative to a modern usage? Like what volume would be used for a modern load of laundry or dish washup? Or is it similar cleaning strength to currently popular cleaning products?
Pretty similar once it's all finished
ive tried and sort of worked, but i did get soap - so thnzz sooo very much!!!! ps i did not die of tasteing it lol
Thank you Sally. In your first soap video you mentioned doing you were doing your PHD. How'd it go? I remember watching that video and being excited about what you'd have to say about the history/origin of soap.
Many thanks for all the wonderful videos and information 😊
There should be a paper coming out fairly soon based on some of my recent research.
@@SallyPointer exciting 😊
Great video
Perfect video for a stormy Texas morning! You may mention it in the video, but I'll ask just in case I miss it: are the wash balls safe for modern appliances, or strictly hand washing? How might I use it in a modern off-grid home with a bucket and plunger type of wash machine?
Washballs are best for washing hands or as a kitchen sink hand soap, the herbs and similar help make the soap go further and add fragrance and texture, but for laundry stick to plain soap
A question: What you have been doing is time-consuming and complex 'pot' chemistry. How did our ancestors get the time to experiment and feel their way from wood ashes and fat through to bar soap? And how did they know what they wanted to get to? What possessed the first person to think that by running water through wood ashes, they would get anything remotely useful? Why would they pour hot fat into it and keep heating it for hours?
Have you seen my article on the origins of soap in the most recent online edition of the EXARC Journal?
@@SallyPointer Nope. Never heard of it. I'm a marine biologist and woodland manager who does a bit of green woodworking.... Thanks for letting me know, I'll go look.
It's quite simple to find out, even in our days. Have a campfire with your kids and clean your greasy pan afterwards with ashes from the fire and water. All three together make soap.
Thank you for that. I think I'll stick to modern methods using commercial sodium hydroxide! Fascinating, though.
Hello! I have just recently found your channel as I am currently attempting to make my own soap from homemade wood ash lye (only I'm using coconut and olive oils instead of tallow)
I haven't been successful yet - it's my third attempt - but I have hope since finding this video!
I do have a question though - would you mind sharing the process you used to clarify the batch of lye you used in the demonstration with the egg? I have been trying to figure it out on my own so that I can eventually make a better quality "white" soap as opposed to the black soap that you get with the high tannin content of the wood ash lye on its own.
Any help, advice or referrals you can share would be extremely helpful and I would be so grateful!
Clearer lye is partly choosing ashes with very little darker charcoal and debris left, but mostly filtering through something like gravel rather than wood which will leach tannins into the mix. Then time. My lye gets lighter with storage.
This is so interesting! Out of curiosity, do you know of other ways to test the consistency without touching or tasting?
Thank you for this detailed video. Would love to try it out sometime 😊I was wondering if one could dehydrate either the lye solution or the oil-lye mix a bit to speed up the cooking process. Would it be safe ? I have a solar dehydrator .
I think it would have the opposite effect. If a batch gets 'stuck' the usual solution is to add more water then reheat, lye needs to be strong, but especially in the early stages too strong is weirdly counterproductive for this method. You can use reduced water ratios when using commercial NAOH or KOH though
@@SallyPointerthank you for your prompt response ❤
Thank you very much for this tutorial. It makes me want to try it. You sad about washing fleeces with it. How does your wool turn out with it? I use french black soap with a pinch of dish soap, since the addition of soda dryed the wool out. Well I'm still looking for the right fleece washing method. Have you tried the suint fermentation method yet? If so, did you like the procede and the result of it? Thank you again for this great video and this pragmatic approach.
I like soft soap for wool prep, a little vinegar in the rinse water can be useful if you feel your water and soap combination is risking any residue, but I don't always do that
What do you use this soap for? what's the PH? Can it be a hand and body wash?
It's a general purpose soap,and if made well is mild enough for hair and body. This batch isn't my best ever so it will be used for laundry and textile processing.

@@consuelochavez984I had a neighbor with bad psoriasis who I used to make castile soap for and it certainly helped.
Question on the used up lye. Would it not be sensible to add it to the next woodash? As some form of reuse?
I think spent lye is probably lacking in the chemicals we are after, so there's probably not much use in using it again. There are historical references for lye in other applications though, so possibly some uses there
can I use shea butter or nilotica in place of beef tallow
You'll need to read up a bit on their saponification values to get an idea of how they will differ. I'm more familiar with shea as a minor proportion of a recipe rather than the sole ingredient
