One thing about drying your Ingot molds, if they're made of iron they can look dry, but as soon as you put them in front of the fire, an amazing amount of moisture comes bubbling out of them. Moral of the story is.. even if they look dry, you should still heat them to make sure they are dry. I hear steam explosions are no fun. Been lucky to have only experienced a small one in a muffin tin so far and learned that lesson quickly.
Hi Jason, the initial weight loss is probably due to the iron getting partially into the borax glass. The lock mechanism on necklaces/ bracelets usually contains an iron steel spring. It might be worth removing the spring prior any purification. Some iron can also come from the mold.
Jason... You build some really cool processing equipment... ditch the Kaowool tubular delight furnace and build the throw down, top of the heap, MBMMllc furnace and make it part of your line!
i done my first cuppel yesterday i had 2.2 grams starting in gold flakes and flour gold from my prospecting came out with 1.07 grams...... it took for ever to finish it seemed but i am very happy that i have learned the process from you jason and ALOT from your vids thank you very much
1.07 from 2.2 looks like huge loss... Placer gold should have more gold, I think... 1.7 from 2.2, well not great but OK... Less than 50 %, I dont know man... could be some gold lost? I just have like 2g that I washed and I want to cuppel it too, Now I am a bit afraid...
Thanks Jason ... I’m glad people asked you about the equipment and simple/ not so simple do it yourself process ... I’ve had tons of questions also.... your the acting do it yourself encyclopedia to the regular outdoors type
Thanks for explaining the truth and being honest , so many people forget that the overall cost of gas and time spent , making ingots out of scrap sometimes just ain’t worth it , I am sure we all have fun doing it , but as for making money well unless it turned back into some fancy jewellery , the only advantage is it’s less storage space ….
Thankyou so much! I'm learning as much as I can and I love how you show the math I'm not good at it so this is a great way to learn about math and smelting at the same time!! Would love to visit your spot! I love crushing ore and smelting and digging for gold and silver
I tryed melting a gold ring and a gold crown I used lead it did pretty good but I belive there's still a little copper in it I just used an acetylene torch it worked well then I did some gold that I've paned over the years I just used borax and it actually turned out better I ended up with a total of 5.3 grams but I'm sure it's not pure I reused the crusable but I see why you would not want to just to much slag ,ive learned a lot and I'm need to learn a lot more thanks for the time you put into these videos to teach us newbies what and what not to do thanks
Thanks again Jason. Very useful video. Love all your stuff. Learning a lot. I understand old CRT's are lead glass, with a lot of lead. I was thinking of melting some down, dropping in some iron, and seeing if I could recover any lead in a cone mold. Sometimes it'snot just about cost effectiveness, but fun and experimenting.
Great video, very informative. I’ve been stacking scrap 14k for a while now and looking forward to getting it refined in a year or two after I get a few oz together.
Excellent video, love the channel. You could have saved a load of propane on you first melt by skipping the furnace and just use a melt dish and propane torch. This is a great way to reduce base metals in your scrap before moving onto chemical refining. It will save you on acids and reduce the wastes you'll need to deal with after. I will certainly consider cupelling on my next run of karat scrap. Keep pumping out the great content on your channel
Yeah, if I was to do it again I would put it directly in the cuple. Its cheap and no labor. Reduces the base metals down to less that 1% and good point about the acid savings for the final steps!
Thank you. I found this to be a very informative video. I have been working on doing the same thing, but was missing some knowledge to make it work well. I now have that knowledge! Thanks for sharing.
Before tax, you paid the same price as the smelter would have paid the pawn shop. The pawn shop came out because it won't have to pay shipping, insurance, etc.
True i’m in the process of doing this right now I’ve done it once before worked wonders maybe I had some trash cupels because some of my gold did stick to the insides of the cupel
You started with 5.494 grams of 14K. Once you melted and dropped the button you had a weight of 5.411 gram button the remainder weight lost was from the spring (Fe,Cr,Ni,Mo) stainless alloy in the lobster claw clasp and zinc oxidizing. Every time I XRF before I melt and after the melt I usually lose zinc % on reading. Zn in alloy reaches the boiling point and is lost in the process.
I like how u explained how not to pour in to a cold or wet cast .. cause it will pop nobody skoolz nobody on how to melt gold .. most just stay quite n say nothing .. ur schooling us on gold melting n gold .. stuff I dint know .. tell us way more tho .. good advice 👍🏼
You should check out Sreetips channel. He refines usiing chemicals, but the point is for small quanities of gold such as what you showed in this video, he uses a torch, no need for a furnace at all.
For the record, asbestos is a rock..well, a mineral with a specific crystal structure. It isn't toxic or poisinous, and it is completely innert. Asbestos is no different from sawdust and fiberglass. It should be a meme, the way people will freak out about asbestos, but will happily breathe wood fibers, fiberglass, and welding fumes.
Really interesting to see this - really like watching @sreetips refine down to 0.999 fine gold, but I often wondered what you get with just a cupel and you answered that question really well! 0.900 fine gold is not a bad result at all for such a simple process - I was wondering if you can scale this up to something like a troy ounce of gold or if the cupel just gets too big. Great video! 👍
@@mbmmllc Very cool! Seems like it might not be a bad step prior to chemical refining - could save a lot of time and nitric acid getting all that copper out first.
@@fredrichardson9761 chemical purification of gold requires quartation. You'll need to add back 3x more copper or silver to the gold, then use a bunch of nitric anyway. The cupelling still has value before liquation for removing some of the tricky base metals.
@@snarky_user Yeah, actually I think this could save on nitric when you're dealing with gold filled scrap. Getting rid of the copper and other base metals would still be a plus if you run a silver cell like @sreetips (he does inquartation with silver). I wonder if cupeling is a superior way of dealing with gold plated material - I think @sreetips demonstrated reverse electrolysis but generally avoids that type of material given the low yield and huge amount of work.
What do you do with the slag? Guest request, you should try to reach out to Gold Rush and get Freddie Dodge and Juan on and do a long video or a few and talk about your equipment and recovery of precious metals, etc. Maybe cross over videos of you and BigStackD.... watching yall makes me wanna move dirt and smelt!
Old white gold can have valuable whiteners in the alloy. Old sterling silver has been known to have other precious metals as hardeners. (it's sterling if the silver is right the hardeners have been platinum or paladium according to what was mined with the silver.
Hey Jason, I just wanted to ask you since the first time I saw your videos. In't there any health hazard from working with ceramic wool like that? I thought the ceramic dust is really bad for your lungs and it's supposed to be covered by refractory cement before you can be around it without a respirator. Also if you're actually reading this: I'm late to the party, but that shot of the Cerro Gordo silver solidifying is in my opinion the money shot of all of the money shots on youtube. The most visually pleasing footage by far. Thank you for that.
Biggest lie in gold is that it isn't durable and needs to be alloyed. It is perfectly fine by itself and adding things is what makes gold easier to break. Any carat gold will break anf 24k will bend bend and last bend you can eventually break a piece of gold but 25k is so malleable while karat gold gets work hardened and will break if you hit it on something or gets squished with the right amount of pressure. Love your videos and did my first 24k cuppel it's only a gram but it is true 24k can hit it as hard as you want doesn't break and only bends like gold should it hasn't broken yet and I hit the thing as hard as I can with multiple hammers and doesn't need to be annealing what so ever. Thanks for the help a while back people like this are truly great teaching others. Also do you find the prices of cuppel to be ok I bought only like 10 but it is a process and to refine steady amount you'll need quite a bit of cuppel
I've enjoyed all of your different idea's for refining gold and silver. Your chemical understanding is off the charts.. The question I have is... I get computer scrap a lot. instead of doing the full chemical methods of getting the gold out. After doing the first acid method to melt off of the boards/chips and leave the gold, could we skip the rest of the chemical/acid methods and go straight to your small electric furnace to adsorb the impurities out?
Is this method possible without the furnace, but using a high temperature gas torch(s) to melt the metals to a liquid then absorb the base copper, zinc, lead into the cupel?
Really enjoy your videos. Thanks for sharing all this valuable knowledge! On that subject... I am attempting to clean up some dirty copper sponge, via smelting. It is contaminatedwith mostly iron nitrate solution, but also, maybe a few trace other base metals. Can you please recommend a good flux to mix in to get this clean enough to purify via electrolysis? Thanks!
4:25 I always thought copper made the green color, and iron made a reddish brown color? I'm also a super novice with no hands on experience with smelting or mining... So I will defer to the actual expert in this case and take you at your word, lol. Thank you for making this video, and sharing it! Very informative and loads of useful and important information. 🙏

Does anyone know if using some borax with graphite crucibles presents any problems? Looking at better way to separate slag from melts
thank you i learned 2 things,1, i learned some math,, and 2, you showed a faster way to do this,,, my next question is about the borax you used, is the same stuff you can buy at the store or do you have to buy from another vendor? this was great thank you
Is there a way, using your smelting methods, to separate the silver from the gold and recover both?
I'd think that can only be done by dissolving the metals
Hey I know this is an old video but I am curious can you do the same method using only a graphite crucible bismuth and borax? or would the borax cancel out the bismuth reaction to the base metals?
I have some placer gold and some gold chains would like to melt them down. Using just borax and a torch maybe.
So if I cut all the gold plated pins out of a computer could I smelt them with some lead in a cupel and end up removing the majority of the steel?
Yep, that would work if there isnt too much Fe
Can you do this without a furnace and just use a hot enough torch as a replacement
That iron that caused the green color likely due to the presence of a steel spring in the clasp
. So using this method the cupel method. Only removes lead copper and other "filler" garbage metals'......
..except for gold and silver....
And i'm assuming the only way to get the silver out of that gold button you have is the hydrochloric acid route? To purify the gold. To 999?
