Super cool video! I love how exited you got. You truly do love doing this and it shows. Great work Goran for providing such an amazing learning experience for all of us.
Hi, Sreetips - adding a little bit of H2SO4 to the water would greatly enhance the solubility of Ag2SO4. About that "I'll turn off the heat, I think I've got all silver precipitated" - OK, but what, if you did not? Once the solution cools down, any Ag2SO4 left (if there would be any) will precipitate and mix with AgCl, and some would still stay in the liquid phase - hmm... I'd use, instead, a hot NaCl aq solution to precipitate AgCl - this way I could see when the reaction stops. That lil' bit of extra water won't make any difference, as AgCl is practically insoluble. Also, precipitating from hot solutions tend to produce bigger particles of the precipitate, thus easier to decant and wash. Using NaCl solution would make the reaction less violent as well, I think - as that bubbling you get every time you add salt crystals has more to do, I guess, with adding physical "boiling initiating centers" than it has to do with reaction itself. The situation we have here is a pure liquid in a smooth container being at its boiling point - but because of its purity and smooth glass walls of the beaker it doesn't have many "initiating/ starting" centers to actually start the boiling - and thus it tends to become sorta-kinda "superheated". The moment you add some "centers" (like, NaCl crystals or other solids, like sand grains) it starts to boil violently - and precisely to avoid such situations, small pieces of crushed ceramic material are added to distilling flasks prior to distillation - to assure smooth boiling of the liquid that is to be distilled. In other words, that "bubbling" is hardly any sure indicator of reaction still going on - my guess is it will produce this effect till cows come home, as long as the liquid is hot enough - at least this is my educated guess, so to speak . And it just occurred to me... That AgCl + NaOH reaction is basically a substitution reaction - in which a strongly basic metal "pushes away", from acidic "rest" a weaker base metal and joins that acidic rest itself. Same goes when one mixes CuSO4 or FeSO4 solution with NaOH solution - the result is Na2SO4 solution and insoluble base of either Cu or Fe (Cu(OH)2 of Fe(OH)2). Typically, such "bases" are pretty unstable, and sooner or latter they decompose into water and oxides of given metal - seems AgOH is VERY unstable and id decomposes into Ag2O almost instantly. What's the point? Well, I THINK that the whole process of converting Ag2SO4 into AgCl could be skipped altogether - looks like adding lye directly to Ag2SO4 would have exactly the same effect - i.e. precipitated Ag2O, that could be decanted, washed and reduced to metallic Ag with glucose or saccharose (a.k.a. "regular sugar"). Whad'ya think - good idea, eh? ;-)
These two videos refining without nitric acid I found to be the most interesting because in my country nitric acid (salt peters acid) is considered to be a dangerous poison. It requires special permits to handle, own and buy. So thank you for showing this process.
Yeah, that's Sweden to you, baby... They won't even allow you to import or keep pure ethanol in your home - while just across the Baltic you can go to ANY supermarket, and buy pure ("rectified") spirit 95% v/v strong, without any limits - as long as you're of legal age, of course. (Which is 18 yrs old - and no, you don't have to show your ID if you look old enough - like, say, around thirty - in that case no one would even bother with checking your age.) Anyway, back to our "extremely dangerous poison" - my guess is one reason to keep it under lock and key is that it can be used to producing explosives - but this is just a wild guess of mine. How to obtain a nitric acid in Sweden, then? Well, the simplest way would be to go to Germany or Poland (or Russia, but I wouldn't recommend it), buy whatever you need and return to Sweden. Yeah, I know - kinda impractical in this "covid times" now. The second path is to use some nitrates (like, ammonia nitrate, a fertilizer) and convert it into HNO3 using sulfuric acid (H2SO4). Still. kinda impractical and troublesome... Or maybe you could just register some small business - like, say, "Metal Viking Precious Metals Refinery and Foundry, Inc." - and then you could apply for those permits? Hey, great idea, innit? Eh? ;-)
Over Eighteen plus I may do a separate video of the whole thing using a piece of sterling flatware now that I kind of know what to expect rather than trying to complete the candle sticks. Make a fresh start.
I hope I can be as good at recovery and refining of precious metals as You and others like Goran!! I'm just trying to learn as much as I can until I am ready to have a proper and safe set up! Just stockpiling as much as I can right now!! Have a GREAT Day!!!
Refining is fun. But it can be dangerous. You don't need to refine the metals. You can just hold karat scrap and sterling silver. They'll track right on up!
@@sreetips I know i don't have to, but I've been having a passion for doing it for the last 2 years! When I found out how dangerous it can be, I told myself that I'm going to take the first step and all the steps after that nice and slow! Also it's giving me time to collect all the items I'm going to need!
Mr. SREETIPS, first off happy Father's Day. I have this 2-part series under my top. During my hands on education process, after I trained considerably melting and pouring, I moved to Silver extracting without Nitric first. As a newbie practitioner. it was painful and generated a lot of waste (one of my mistakes is that I accumulated 7-8 lbs of silverware from Thrifts and decided do everything at once). Anyway, I took my time and proceeded with high volume of liquids to re-process and avoid too much waste. I also found out a way to process AgCl directly without going through NaOH and Sugar. Boil AgCl in water. Let it (almost) dry, mix about equal weight of Na2CO3, some borax (references say 40% of Borax for 0.995 purity, I did not use that much), melt it in a ceramic dish. After cold, break off the flux crystal. This also worked for me when, after NaOH and Sugar, the salt was dark brown or black. Sorry if too basic, since I have not seen this process anywhere, just sharing my learning. Been suffering but learning from mistakes. Cheers!
You sure have rock steady hands my friend. It will be really interesting to see what your stock pot will produce. Who knows you may discover some new mystery metal eh, LOL. When you were introducing the salt you sounded like a kid in a toy store. It was kind of funny for sure. I am with you on learning something new every day. That lump on our shoulders would rot without that for sure.Great fun today for sure. I have never seen you happier my friend.
Hello Mr. Sreetips, I recomend to you the Textbook of Qualitative Chemical Analysis by Arthur I. Vogel. This textbook describes the reactivity of all metals and his compounds and i believe it will help you a lot to understand and identify whats going on on your reactions. At least helped me a lot when i was majoring chemistry.
awe, i wish you did do the final conversion and melt in this video, yea we have seen it.. but something about that completeness and closure.. its nice. ;) haha
Also I have done this de-plating silver off of silver plated items in Parana solution sulfuric acid and nitric acid. I did use salt water instead it seems to work pretty good.
My takeaway was to heat the considerable amount of water to boiling prior to adding the cooled sulfuric acid and silver. Keeping the silver sulfate in solution and able to react with the sodium cloride.
Joe, some have suggested that the sulfate will convert to oxide with sodium hydroxide just like the silver chloride does. If that's true then just add salt to the whole bloomin thing and done.
Could you drop the silver from the silver sulphate solution with a piece of copper? Also, I think conversion of the solid chloride can be done if you let it touch a piece of zinc in slightly acidic water.
You could try adding the sodium hydroxide directly to the silver sulfate solution, skipping the sodium chloride step. The silver oxide/hydroxide should come out just the same, leaving behind sodium sulfate.
Seems like a good idea to weigh the sterling silver into the solution and to weigh the recovered silver output. With the blue tint in the sterling sulphate solution would a cold filtration be beneficial to remove copper sulphate? Just to reduce the impurities carried over to the ingot.
Woah! No way! Dang.... Almost missed a bit more than half of your total yield... Yikes! Thank goodness for the fellow viewers! @Goran ..... Right on.... 🤘👍 @Sreetips .... I loved the comment about your doctor in the last one.... Jerry Atrics.... 😆 as for diet, do you only do raw, or do you cook the veggies sometimes? A friend turned me on to a baked recipe of Brussels sprouts that i can eat as a snack anytime of day... and I don't normally even like Brussels sprouts...
I love raw veggies. Always have. But I'll have a big bowl of shrimp and grits every now and then. Plus I'll get a hankerin for two big rib eye steaks and onions over hot coals.
G'day sreetips I'm glad you are back making videos again! Like or ways I love watching your videos some times people in the comments. Do help out a lot as you know now keep up the great work buddy I look forward to seeing the next video.
I would be interested in seeing if the silver sulfate can be converted to silver metal with the lye/sugar method. If you have the time and material, please give it a shot!
I've got a ten-year-old datatainer of used photo fixer prepared from distilled water. There's definitely silver in the solution but there's a whole bunch of white and green precipitate as well. Any idea what that is? I read somewhere that sulfur can fall out of the solution.
I’d put a small amount of the precipitate in a small beaker and experiment. Hydrochloric first, to see if the green dissolves and if the silver comes out of solution as silver chloride.
So I am have been looking around and see that you can convert silver chloride by adding water to just the top of the silver chloride and add 1/10th the amount of sulfuric acid and stir with a iron rod. Have you ever done this? If this is the case seems a lot easier and less messy than the lye and sugar.
@@sreetips thanks for replying. I'm gunna give it a shot next time I'm ready to re-do my silver cell solution. I will post a video of how it goes as it takes so much washing to get all the burnt sugar and lye out of the silver chloride just gunna see if this is a bit easier. One other question why would you not always do the silver chloride method over getting the silver out with copper?
When you try the paper coffee filters (paper because they do not tell you what polymers go into the other types), I would use them mostly for initial filtering... Depending on the quality of the filters, they could be used for more. I had worked in a few labs that successfully used certain coffee filters for recovery, but it was 20 years ago, and I would not trust any made outside the US/Canada... (Western Europe also, but I doubt you would find any from there).
Now the fun question: was it necessary to dissolve the silver precipitate prior to adding the sodium chloride, or could you have had a solution of hot saline ready to receive it for conversion to begin with?
Hi sreetips! I just saw this, and realized you figured it out! Here are a couple cool things you could try for fun, and also for research. 1. It should be possible to create silver oxide directly from Ag2SO4 as: Ag2SO4 + 2 NaOH = Ag2O + Na2SO4 + H2O, but I couldn't find a reference for it, only formation of AgOH, which should work the same. 2. You could also take AgCl powder, spread thin on a tray, and expose it so the sun uncapped to produce pure silver as: 2AgCl(s) → 2Ag(s) + Cl2 Keep posting! :-)
Hey Sreetips, you might want to put salt into your waste silver nitrate after dropping the silver using copper. If there is ANY silver left in the silver nitrate, the salt should drop it out as silver chloride.
Kiwi Refiner is correct, the silver chloride would go up in a toxic cloud or form a greenish slag. A common way of refining gold is to blow chlorine gas into molten gold, any contamination turns into chloride and boils off before gold does. You just have to time it right so you don't boil off a bunch of gold chloride too.
sreetips I know he used clear ammonia to dissolve AgCl from his gold powder. It does send gold powder colloidal though (I don’t use it) He has a lot of great washing techniques I use though
It's a straight 'Double Displacement', 'Double Replacement' or 'Metathesis' reaction. (they all mean the same thing - the bits swap places) Ag2SO4 + 2 NaCl => 2 AgCl + Na2SO4 If you had thoroughly dried and weighed the Silver sulphate, ~69% of that weight would be actual Silver metal, plus you could calculate in advance how much NaCl to add. e.g. if it had been 50g of dry Silver sulphate, you'd need around 19g of table salt in there. The maths say the absolute Max yield of Ag metal would be around 34g Stoichiometry saves some of the guess-work, but certainly not all.
@@sreetips Cool ! If you choose a quantity of Silver to start with, e.g. 10g, and the % strengths of your acids, i'll calculate out the required amounts of the acids for you, if that would help.
so a cost comparative please. is it cheaper to use this method or the same cost? it seems like it would be cheaper to me. will you continue using it or go back to nitric acid?
Folks, today is the day I planned to run my first batch of Silver using the H₂SO₄ method. Thnx Mr. sreetips. As per advice from Mr. sreetips I will not bring the H₂SO₄ to boil. After I have Ag in solution, I will bring it to a moderate heat (warm it up basically) and add it to hot water, this way I am expecting that all - or most of - AgS gets dissolved without the need of the extra step. I have 3 beakers to have a moderately small weight of Ag being processed in each. For those interested, I am keeping a video log in my TH-cam. Let's Rock.
sreetips The idea is to warm up the acid before pouring the water. Dont want to leave the beakers with acid in the heat, only at the end. So I will be poring warm acid into warm water. Thank you
Three medium sized beakers, absolutely the same one, more or less same source of flatware, silverware, slice trays. One beaker is bluer than blue and reacting - bubbling a lot, the other two not so much. Suspicious about a piece of a jar I put there, since there is another piece, testing in the 3rd beaker just to see if silver contents is the case.
@@sreetips well i have evaporated all the water from the waste(was like a muddy water) now its like a dry dirt. could i send you a little bit to play with?? see if you can figure how to recover silver
so if i understand correctly by adding sodium chloride you have separated the silver and sulpher and in essence made 2 products silver chloride and sodium sulphate with some hydrogen gas released and possibly burned some sodium off as well?
I was just thinking that was why the yield was so low. Since silver sulfate is insolvable that’s why it crashed out when it was added to the water. As long as the solution was hot it could keep it dissolved but as soon as it cooled down the game was up. I wonder though if you could just do the lye and sugar treatment directly to the silver sulfate. 🤔 it might work anyway. 🤷♂️
Hi sir I'm from India and I'm a big fan of yours, can u help me out with one question? What is the weight percentage of silver in silver nitrate and silver sulphate ? Please help me out?
I still think you can just add lye directly to the silver sulphate. That should make silver oxide and sodium sulphate, which will stay dissolved in the water.
sreetips from what I’ve been reading sulfuric acid is the preferred method in Australia and England. Here is the Link to what I was reading. Let me know if this is of anything help to you. I’ll try this as well. www.911metallurgist.com/blog/sulphuric-acid-parting-gold-silver
wow, I have about 1.6 lbs of this that is all dried out, I am going to try this method. the 1.6 lbs has some copper and palladium in it but I have no way to melt the palladium.
@@sreetips mostly wondering if it would be cost effektive to setup a destiling station that can run in the background as its a important product in your refaining process
@@sreetips Note that distilled water absorbs plasticizer from the plastic container... glass distilled or double glass distilled and stored in glass is considered best. Now the plasticizers SHOULD NOT interfere with your work, but you never know. Distilled water picks up silica and other components of the glass used (avoid green glass -- iron), but glass bottles were the storage containers used for most of the past 100+ years.
I've got everything from both candle sticks. But I forgot to weigh the sterling before I dissolved it. I'll get another batch going with a larger amount of Sterling so we can get a nice big bar of pure silver and a yield number. should be close to 90%.
Still haven't solved your exhaust hood problem I hear. In addition to the constant whining there is now a grinding rumble that does not bode well for the near future.
Quite right. I've ordered a new motor, "F" insulation rating, fully enclosed, sealed ball bearings, 1/3 HP. I'll just need to fabricate an adapter to mount it and machine the 1/2 inch shaft down to 3/8 so I can fit the fan on it. That should solve the problem.

Mystery is solved . Pls let know how much was total yeid all together on that stand
I'm gonna guess its close to 28 grams of .999 fine silver. The candlestick before refining was like 30g

@@sreetips yeah boiling that stuff is brave. But you have a nice hood for it.
could there be Germanium in mixture , it added to some silver alloys to reduce tarnishing
Do you recall the yield of the remaining silver from the silver sulphate?

IV learned so much from your videos!!!! Thanks sreetips...
Hi sreetips! I just saw this, and realized you figured it out! Here are a couple cool things you could try for fun, and also for research.
1. It should be possible to create silver oxide directly from Ag2SO4 as:
Ag2SO4 + 2 NaOH = Ag2O + Na2SO4 + H2O, but I couldn't find a reference for it, only formation of AgOH, which should work the same.
2. You could also take AgCl powder, spread thin on a tray, and expose it so the sun uncapped to produce pure silver as:

Thank you, I'm going to try a much larger batch and try the silver sulfate to silver oxide with NaOH. Then reduce to metal with sugar.
Ty for showering that! That is absolutely need to no for me I’m sure
Thanks a lot for this video but I'd like to know if this process can be used to refine gold
Hey Sreetips, you might want to put salt into your waste silver nitrate after dropping the silver using copper. If there is ANY silver left in the silver nitrate, the salt should drop it out as silver chloride.
I love your videos! One question. Why don't you just melt the AgCl to obtain Ag, and leave out the lye & sugar steps. AgCl melts @ 455
C.
Forrest Secord chloride has to go somewhere when melting. Turns into gas and is toxic and isn’t recommended
Kiwi Refiner is correct, the silver chloride would go up in a toxic cloud or form a greenish slag.
A common way of refining gold is to blow chlorine gas into molten gold, any contamination turns into chloride and boils off before gold does. You just have to time it right so you don't boil off a bunch of gold chloride too.
Didn't Harold_V use sodium carbonate flux to reduce the chloride to pure silver metal? I seem to remember a post by him on that on the Forum.
sreetips I know he used clear ammonia to dissolve AgCl from his gold powder. It does send gold powder colloidal though (I don’t use it) He has a lot of great washing techniques I use though
Sreetips were you in a band?! I was studying your videos and one of them was tagged with that information but I couldn't find music right away.
Yes, Two Common was the name of our band.
It's a straight 'Double Displacement', 'Double Replacement' or 'Metathesis' reaction.
(they all mean the same thing - the bits swap places)
Ag2SO4 + 2 NaCl => 2 AgCl + Na2SO4
If you had thoroughly dried and weighed the Silver sulphate, ~69% of that weight would be actual Silver metal,
plus you could calculate in advance how much NaCl to add.
e.g. if it had been 50g of dry Silver sulphate, you'd need around 19g of table salt in there.
The maths say the absolute Max yield of Ag metal would be around 34g
Stoichiometry saves some of the guess-work, but certainly not all.
Aga, will the silver sulfate convert to silver oxide with NaOH like silver chloride does?
@@sreetips It should drop out of Silver chloride, nitrate or sulphate solution. I've never done this, so cannot guarantee it.
New experiment, thank you.
@@sreetips Cool ! If you choose a quantity of Silver to start with, e.g. 10g, and the % strengths of your acids, i'll calculate out the required amounts of the acids for you, if that would help.
I am really enjoying your videos. I just find them so enthralling and I can’t explain why.
I watch them while on the elliptical at the gym. Makes the time fly
As long as it flares up when the salt goes in, it's got something left to react with.
Doesn't natural sea salt contain other minerals that would contaminate this reaction?
so a cost comparative please. is it cheaper to use this method or the same cost? it seems like it would be cheaper to me. will you continue using it or go back to nitric acid?
I may try a large batch of Sterling with sulfuric acid.
Nice what was the final weight of Ag recovered?
Sorry to say I didn’t weigh it. I probably threw it in with all the other silver and ran it thru the silver cell
Please do a video on extracting the sodium out of solution, now that would be cool.
Folks, today is the day I planned to run my first batch of Silver using the H₂SO₄ method. Thnx Mr. sreetips.
As per advice from Mr. sreetips I will not bring the H₂SO₄ to boil. After I have Ag in solution, I will bring it to a moderate heat (warm it up basically) and add it to hot water, this way I am expecting that all - or most of - AgS gets dissolved without the need of the extra step.
I have 3 beakers to have a moderately small weight of Ag being processed in each.
For those interested, I am keeping a video log in my TH-cam.
Let's Rock.
Pouring cold sulfuric acid into boiling water could cause a violent reaction and spatter hot acid all over the place.
sreetips The idea is to warm up the acid before pouring the water. Dont want to leave the beakers with acid in the heat, only at the end. So I will be poring warm acid into warm water. Thank you
@@Ziegen-Sauger No worries, just a warning. Pour it in real slow.
sreetips SUPER THANK YOU!!!!!!
Three medium sized beakers, absolutely the same one, more or less same source of flatware, silverware, slice trays. One beaker is bluer than blue and reacting - bubbling a lot, the other two not so much. Suspicious about a piece of a jar I put there, since there is another piece, testing in the 3rd beaker just to see if silver contents is the case.
What’s the best way to recover silver from tollens reagent? It’s the waste from silver nitrate plating glass to make mirrors. I have a lot of waste.
Add some salt to a small sample to form silver chloride, if present
@@sreetips well i have evaporated all the water from the waste(was like a muddy water) now its like a dry dirt. could i send you a little bit to play with?? see if you can figure how to recover silver
so if i understand correctly by adding sodium chloride you have separated the silver and sulpher and in essence made 2 products silver chloride and sodium sulphate with some hydrogen gas released and possibly burned some sodium off as well?
I'm not familiar with the stoichiometry. But I recognize, visually, the silver chloride.
Sreetips is awesome!!!! Navy man
I was just thinking that was why the yield was so low. Since silver sulfate is insolvable that’s why it crashed out when it was added to the water. As long as the solution was hot it could keep it dissolved but as soon as it cooled down the game was up. I wonder though if you could just do the lye and sugar treatment directly to the silver sulfate. 🤔 it might work anyway. 🤷♂️
Never hurts to double check
Well done!
Thanks goran.
Hi sir I'm from India and I'm a big fan of yours, can u help me out with one question?
What is the weight percentage of silver in silver nitrate and silver sulphate ? Please help me out?
I’ve never calculated the weight percentage in the silver nitrate or silver sulfate. I don’t know. Sorry
You got some great viewers @sreetips!
Hit Like button!!! :D
You are first, now I must get some sleep. Thank you.
@@sreetips you're very welcome!!! :D
And see you later friend I getting off too!!! :D
Super reactive with the salt while boiling.. Wow cool
✌️PT
I still think you can just add lye directly to the silver sulphate. That should make silver oxide and sodium sulphate, which will stay dissolved in the water.
Have you tried converting the silver sulfate with sodium hydroxide to silver oxide yet? Very curious to see if that works.
Not yet. I’d like to get that yield up. So we can refine silver with no nitric acid.
sreetips from what I’ve been reading sulfuric acid is the preferred method in Australia and England. Here is the Link to what I was reading. Let me know if this is of anything help to you. I’ll try this as well. www.911metallurgist.com/blog/sulphuric-acid-parting-gold-silver
wow, I have about 1.6 lbs of this that is all dried out, I am going to try this method.
the 1.6 lbs has some copper and palladium in it but I have no way to melt the palladium.
+sreetips By the way, when say sugar is it glucose or sucrose?
Sugar from the grocery store
@@sreetips Yeah, but both sucrose and glucose can be found in a grocery store.
I can’t tell the difference. I use it in my coffee
@@sreetips Maybe there´s some information on the composition written somewhere in the package.
What is the pH of your solution post-salt?
That was awesome
Very interesting. 👍
just saw the previous video today was gonna say it was silver sulphate but was sure youd had figured it out
So would you suspect that the gas coming off the silver sulfate solution when you add the salt is SO2? Any chemists out there?
Ya that cold makes the silver pop out

do you destil your own water?
I buy it at the grocery store. Most of it, about 80%, gets used to rinse my glassware after washing with tap water.
@@sreetips mostly wondering if it would be cost effektive to setup a destiling station that can run in the background as its a important product in your refaining process
@@sreetips Note that distilled water absorbs plasticizer from the plastic container... glass distilled or double glass distilled and stored in glass is considered best. Now the plasticizers SHOULD NOT interfere with your work, but you never know. Distilled water picks up silica and other components of the glass used (avoid green glass -- iron), but glass bottles were the storage containers used for most of the past 100+ years.

Would it b posible 2 do some other other metals pure tanttium wills b cool
Wait - what was the yield?
Awsome video
And was this a cheaper method using household ingredients?
I believe so. But it may be very close to the same for each. Depends on what has to be paid for the acids.
You got to film the rest we need to see the yeild!!
I've got everything from both candle sticks. But I forgot to weigh the sterling before I dissolved it. I'll get another batch going with a larger amount of Sterling so we can get a nice big bar of pure silver and a yield number. should be close to 90%.
how many of you guys would've added the salt by the teaspoon?.... I know I would have....LMAO!!
Was I right or was I right. :-D
I wrote the above before seeing the comment in the video! Great! :-D
I was having a quiet evening. But I couldn't resist doing the experiment. Nice one!
The comments on your videos are almost as fun as watching your videos. :)
Thanks, Goran and sreetip
I had a feeling it was silver sulfate.
Got to be honest awesome sreetips
Still haven't solved your exhaust hood problem I hear. In addition to the constant whining there is now a grinding rumble that does not bode well for the near future.
Quite right. I've ordered a new motor, "F" insulation rating, fully enclosed, sealed ball bearings, 1/3 HP. I'll just need to fabricate an adapter to mount it and machine the 1/2 inch shaft down to 3/8 so I can fit the fan on it. That should solve the problem.

@@sreetips Now your talking, must have watched a few episodes of Tool Time.
Mortons salt has sugar in it.
I thought your yield was extremely low but I couldn’t tell you why.
The heat will break the Cl bond and leave pure Ag. Caution, must be done under a hood or outside!
If you suggest to just melt it, it won't work. Silver chloride melts and boils, producing a toxic cloud of silver chloride.
@@goranaxelsson1409 Correct
Harold_V said that he used sodium carbonate flux to actually melt the pure silver from silver chloride. I've never tried it.
wow it's rare to see you use a clickbait-y title lol
I was truely amazed at how much of the silver got tied up in that sulfate.
I have watch some videos over 12 times lol
Silver ormus
All this from plated candle holders? This doesn't make any sense.
Sterling.
They weren’t plated, they were weighted.
