- Wow! What an amazing battle. The end/winner was a total surprise to me.
Lye is not for kids to play with. Mix lye in water where well ventilated. Never mix water in lye as the result is hazardous. Don't mix lye in a non-tempered glass as you can see my mix reached 190 degrees.

Enjoyed watching. Really helpful
I enjoy your videos and look forward to seeing more!
Angel, I am encouraged to press on. Thanks.
I am surprised at your conclusion - I thought the corn starch one gave a much better shape in the end - did you know there is another formula using corn starch -- add some mineral oil to it and that makes it easier to work with.
Wow, so helpful! But I was surprised that you chose the Dawn mold. I thought surely you'd choose the mold made with cornstarch. I'm new to mold-making, but I make molds for polymer clay instead of soap. Thanks for doing all the heavy lifting for a newbie!
2 things. you can take and put your silicone mix in one pan and press the other one over it easy and it will help form it and give it a uniform thickness. Second when demolding take a can of conpressed air like keyboard cleaner. and shoot it in between the mold and soap. will pop the mold free
A couple of really good ideas Nathan. I esp like the compressed air idea. That alone makes me want to try again.
With the constancy one you have to add a fair amount to the silicone but you should also add some oil, I use baby oil which blends in nicely
Love the video, i am a newbie to soap making and i think the molds are great and the soap is awesome. Still trying to get my head around the soap calc.
Bex it helps to have an experienced person show you the ropes. I did. But after that one lesson I was on my own. There certainly are lots of beginner lesson on YT. Soaping 101 comes to mind. Post if you get started and how it went. Good luck.
Maybe you could also try putting an edge on the mold making it easier to remove!
What about a silicone coil at the top to give yourself something to grip when releasing from the soap? It would also add some rigidity to the rim of the mold, hence, wouldn’t tend to bow as much. Thank you so, much, for your post. I do pottery/ceramics and I’m learning to make molds for surface design. 👍😀
In my sculpture classes in college we found that using RTV silicone set up better and made a better mold. We used the dawn method. Sometimes the cheap silicone would never set up at all.
Silicone will mold around silicone. You can just take some more silicone and mold it around your first mold to strengthen it. The one with thin spots you can just take pieces of fresh silicone ( with dawn) and smooth it over those areas.
You could try using gauze to reinforce the cornstarch dough or even the straight silicone. Put a layer over your shape, lay gauze over that and then cover it with more gauze. Alternatively, just spatula silicone on the gauze and lay it on in strips until the thing is covered.
A most excellent idea.
I have several videos up of me making silicone molds for soap making and bath bombs.
Thx!!
Welcome!
Thanks for that good video
24:40 aluminum reaction.... either from proximity or there's a leak and the lye got in and reacted.
Looks to me that you should try using detergent/silicone for the inner layer but reinforce it with starch/silicone outer layer ?
Hmm! Interesting. Very interesting.
I wonder if you put rubber bands into the molds at the corners when you make them, if that would keep them from tearing too easy.
Love the intro!
Thanks for noticing, and saying so.
I use caster oil as a superfatting, and olive in larger quantity. Same results but cheaper
Seriously....loose the aluminum pans. And if your soap turns bright orange and emits fumes....that's the aluminum reacting to the lye so if that pan touches the soap....that will be an issue.
Palm oil can be found in the organic section of Kroger's under the name Spectrum organic shortening. Costs about 4.00 for 24 oz
Wow! Now that is something I will look into. Spectrum is now on my list.
Have you had a chance to you both of these molds since? I'm just wondering if they performed the same with 2+ uses? This series was fantastic and answered exactly what I came to TH-cam to find out today!
Yep!
I don't think you worked the cornstarch long enough
I fully agree Nick. The cornstarch should be worked until it is a uniform putty like consistency rather than all powdery and dusty. For ease of use and uniform finished product, cornstarch wins in my book everytime. Like Nick says though it needs to be worked longer to make a valid comparison. If it was setting up too fast it was due to the ten minute delay while you dealt with the postman, not a deficiency in the cornstarch method.
Nick Doe with the dish soap mold he added soap as a release agent before adding the silicone. On the corn starch mold he didn't put any thing on the pan as a mold release agent before adding the silicone.
Trace...16:40 right there. That's a light trace. You poured at thick trace. Aim for light to medium trace if you want to design or add fragrance. Light is better because some scents will accelerate trace....and give you soap that's bionic if you aren't ready for it.
I have heard that it is the glycerin in the soap that makes the silicone workable. Have you tried using only glycerin?
never tried glycerin yet Ron. I do wonder enough to try it.
Hey mouse, try making a silicone mold and after it sets make a batch of silicone and corn starch and spread it over the regular silicone mold for strength.
I remember the old song where; 'Uncle Buba swallowed a bar of Grandma's lye soap, he has the cleanest ulcers in the land". Everyone join in the second verse...
I bet it cleaned up his speach!!! funny!
Love it!😀
Hi Mity Mouse Love the video. Here is a heads up Big Lots sales larger jars of Palm oil and coconut oils cheap.
I will have to check that out. Thanks
Run a bead of silicon a round the rim of your mold// perhaps two or three beads this will act ass an exterior band or rib if you look at it that way..
Ya know Willi, that is a really good idea.
Will homemade silicon allow toxins into soap
Can you dry the soap out in a dehydrator designated for soap only?
I suppose you can. Not sure what it will do to the soap characteristics.
You can but it’s not just about drying or letting the water evaporate from the soap. There is still a chemical reaction going on with the oils. A natural cure is best. You can use the soaps safely after 2 weeks but the soap will not last as long as a hard fully cured soap.
I noticed you didn't fragrance the soap. I wonder what effect that would have especially on the cornstarch one. Also I've seen people use baby oil in the cornflour one. Did the soap smell like silicone? Great video. Thanks for sharing 😀
Nicole, I am allergic to most fragrances, so I quit using those. The soap smells like soap. But when I use olive oil the soap starts to stink, like it is not keeping well. So, just stick with simple ingredients. Thanks for the compliment.
Baby oil has a mineral oil base (which is the oil another youtuber suggested) for the silicone / cornstarch mold. Is mineral oil chemically preferable for this process ... or can I use vegetable oils, like sunflower oil for instance?
Is the silicone mold strong enough to turn inside out?
hmm???
Hi Josh, Silicone caulking is not flexible enough to be able to turn inside out. If you were looking for something that you could do that with, then you would be looking at something more like Platsil Gel 10 which is used for making Prosthetic
could use a ice water bath to cool lye water faster
Might be another good idea.
The cornstarch actually was better. The mold has weak spots which is why it ripped and you need a lip or a recess ...like most silicone pans. And it was stronger....more structurely sound. So I vote for the cornstarch pan....now add some silicone to repair the rip and continue on.
Good idea re having a lip. With a good strong lip, perhaps there will be no tears.
Music drove me nuts... had to turn vol off.. and did you use drain cleaner??? 🤔🤔I guess I never knew what Lye was., How is it not dangerous to use on ur skin? Sorry Im just new to all this and it's very interesting.
When I was a newbe at soap making, I thought the same things. But I had a chemist explain what the saponification process does to all the ingredients. It creates a great lump of "soap". Now I can clean up my act.
I am attempting to loose weight. You soap looks like frosting covered something delicious. Yikes! I am a lost case......still thinking about eating your beautiful soap. Sorry.
How about a combo trial using various ratios of dawn to cornstarch?
I'm thinking about it.
did anybody notice he only used 26oz. of water instead of 32oz. Remember there are 16oz. to the pound and he only used 1lb. 10oz. for his total. My guess is he forgot to go to 16oz. to get 2 lbs.
I found these two videos to be very informative. I had to look up why lye must be used in soap-making, because at first I thought you must be a tar-worker or something to need so much lye soap around. Now I realize that lye is used in all soap-making. (Live and learn!) I really enjoyed your videos. I find that these 'regular man on the street' type how-to videos are a lot more informative and trustworthy than the corporately-sponsored professional ones, which are usually nothing more than a thinly-veiled sales-pitch for this or that product. Here is a question though: Why does every video I've seen about this always use Dawn dish-washing liquid, and never any other brand? Is Dawn special in some way? Was the whole two-part video series sponsored by Sunlight, to discredit Dawn??? (After all, cornstarch took the belt.)
Yes, I know Dawn is what they use to clean oil off ducks caught in oil-spills, and all of that, (applause from me) but what is the chemical difference between Dawn and any other dish-washing detergent?
Wow! What a nice compliment, Laura. Thank you. Made my day. When Mity Mouse does the dishes, he uses Dawn. It's the best grease cutter and the only soap on hand. Haha, ironic it is that everyone uses it for soap molds.
I used to be an Ajax man because of that Ajax squeak commercial 150 years ago. But the "spousal unit" has convinced me that spending a few more pennies on Dawn does a much better job on cleaning. Been nearly 20 years since I switched and never looked back. Too funny.
I stumbled upon Dawn 30+ years. It was on sale! I have not stopped using it. My experience with it is the same as stated above. After living in “oil country” I learned that the men used Dawn exclusively on the rigs for many years. That is why they started using it on the wildlife.
Any particular reason you don't just buy a silicon bread pan? They make them.
I do. I was settling something in my mind here.
why the LOUD music at 18:00. Blasted me out of my Seat !
Frankly your soap recipe isn’t a very balanced one so that’s why it thickens so fast. If you want a soap that doesn’t set up so fast drop your palm down and add in some olive oil or other liquid oil. It will be a more conditioning soap too since palm is a more drying oil. Using primarily palm and coconut oils isn’t going to give you as moisturizing of a soap compared to other handcrafted soaps but it still beats store bought- lol
Your palm oil can also give you spots and the clouding you are mentioning from the stearic acid in it. You really should heat the entire container of palm oil and stir it well before dishing out what you need because the stearic acid will settle to the bottom unless you buy the no stir type that has been treated so that it doesn’t do that. Not doing so will mean more stearic acid is in the bars made from the bottom of the tub which cam cause your soaps to have white spots and throw off how your recipe behaves. It’s not so much an issue just making plain soap but if you want to get into fancy colors and adding scents it can be problematic.
For an easy recipe using what you have for the most part I suggest 5% castor, 25% coconut, 30% palm and 40% olive oil.
Great video! I had thought about trying to make the diy molds myself but didn’t feel it was cost effective.
Mesha, I have shared your comments with others. I have been happy with my formula for 5 years now. I have experimented with other oils and fats to make a softer bar, but my skin only likes my formula. Lastly, i had never thought about my oil needing stirring because it is a solid or semi solid at room temps. But, you may be right and I will stir next time. Thanks for your input. I am about to make a new mold video in a couple of weeks when my new mold arrives. Let me know what you think. Thanks.
Should've used olive oil smeared in it.
Another YTer used mineral oil to make the silicone mold more pliable. Are you referring to that? I wondered whether other oils could be used ... or whether mineral oil was chemically preferable.
Wear Google's.... EVEN WITH GLASSES, and a mask as well
Go wash your hands! They’re covered in soap!
that music in the middle was so annoying I wanted to close the video but instead just skipped ahead. If that is the purpose just cut that part out of your video. The music was a bad idea.
Bryan! That is the kind of input I really need. Thanks for being gut honest.
Please cut that "rust" off that's from the aluminum. And wear gloves...if the soap has a hot spot you're not protected. Also... litmus strips are your friend.
Hi peepla7. You make some great points, thanks for all the input. Pretty sure I used stainless steel pans (scratch test wise), and accidentally used city water not distilled on one.
Aluminum does not rust, the oxide produced is white.
Iron, and stainless will rust, and since lye is a powerful oxidizer it will cause a reaction to both iron based alloys (stainless has nickel and while it will rust, won't stain the metal like stright iron would be) and aluminum produces a hydroxide and gas that is very harmful. Plastics like hdpe (research is needed since I don't remember if my reacts with this or pet) are the way to go, or straight silicone
I don’t understand why you’re even making a silicon bread pan? What’s the point? Your making soap ya?
IKR...I thought I could conquer the world with a great invention. BAH!
OMG stop with the LOUD Music ! Again @20:00
YOU TOOK THE TIME TO PUT THE INFORMATION TOGETHER... HOWEVER, YOU FORGOT TO EDIT YOUR VIDEO, CAN NOT HEAR WHAT YOU ARE SAYING, JUST A BUNCH OF MUMBLING, WHAT A SHAME.
Johnny, thanks for the input... I hope to purchase Camtasia soon so i can do some real editing. Been using this lousy Windows Movie Maker far too long. Ug.
I didn't have any issues not hearing you clearly. I understood everything you said. I think it was a great video. Plus it was a twofer, modes and soap making tutorial. Thank you!
Your making a soap mold the size and shape of a bread pan ?? Use the dam bread pan as the soap mold !!!!!!!
He originally was, but it was sticking too much & was too hard to get out of it.
You can’t put the raw soap into an aluminum pan because the lye reacts with it.
