Thank you so very much for making this video. I never felt like you were dragging on, you get to the point while still being detailed for someone learning how to do this. You are so appreciated.
awesome job Jason :) so cool how you explain all the details :) and show all the practical side of things :) great to watch :)
This one was great. Answered a lot of my questions from watching a bunch previously. Interesting stuff. Thanks for sharing!
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.
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.
Really fascinating and well presented with a LOT of useful information!! Thanks!
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.
Great to see you testing the metal contents. More of that in your future videos please!
Great Video...You are the BEST metallurgist on youtube....THANK YOU.
Thanks!
I try to refrain from comments as the audience is a huge swath of folks from far left to far right and this shows on their concerns and comments. Personally I find that you are a guru of smelting and refining knowledge who has started to grey a little, you still breathe well, still have all your fingers and are quite mobile so you obviously know about the dangers in your profession.
Personally I have zero comments about your ability nor professionalism but would as usual like to thank you for the time you spent making, editing and ULing these videos for me to ride along with you and watch a master at his craft.
Thanks Jim! I really appreciate that comment
Right on Jason ✅
This was fun 👍🏻
Hi Jason and Rigby, greetingd from Czech Republic. Today I had a good day, almost 0.5 g and my first picker ever (5 mm = 1/5 inch, 46 mg).

Great video Jason. Thanks for explaining things in a little more detail, you answered many questions.
Thanks for watching
Always wondered how to separate the gold from other metals. Now I have more questions 😀😀
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
Awesome! Two birds one stone!
😂 9:00min mark. Made me think of microwave popcorn. When the popping stops, it’s ready
Hey Jason, Awesome video. You do an incredible job explaining the little details! Much appreciated! Jim
Thanks Jim!
Thanks for doing this video Jason! I always like learning more about gold and precious metals!
Thanks for watching!
Been looking forward for you to do something like this for awhile! Yay
Thanks Jason very informative and ad
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.
Thanks!
Jason, this was such an informative video and I’m sure it will help lots of fellow watchers! Thanks

Thanks man. Glad you enjoyed it
Downloading this for future experiments. Thanks
thank you for sharing your nice process sir..
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.
I really enjoyed this video , I’m learning so much! Subscribed 👍
Excellent information and process.
Thanks.
Thanks
This was very helpful thank you
I just learned so much, thank you!
Wow never thought of that!
Great as always Jason!!!
Thanks for the information
I really like that you showed your math. Great video.
Very good explanations on the process. Pretty interesting too!
Thanks!
Great tutorial. Thank you
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!
Cool stuff.
Thank you Jason 👍
Glad you enjoyed it
Thanks Jason for all your informative content. Quick question, if i wanted to convert flour gold into a button and pull off other base metals would i need to make the button first or can the flour gold go into the cupel with lead and skip the melting a button step? Also with using lead instead of bismuth what would the ratio be roughly?
Awesome awesome so much information keep it up man great videos..👍👍👍👍😎
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
That video answered a lot of my questions. Thank You.
Thanks for watching
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 ….
Interesting video friend thank you 😊from Scotland 👍
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!
Thank you.
Question if I may.
What's the best way to sell gold jewelry I find? Melt and refine it as you did or just sell as is, at a place that buys gold?
Thanks again
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.
Wow thanks that's a super easy way to refine your karat gold 👍
I love your videos I appreciate this one especially... is that a regular crucible you’re using
Nicely done! Thanks for sharing!
It's better to turn that gold into jewelry & sell it than it is to lose 10% selling it to a refiner.
Great job
Really cool video, remember next time there is a steel spring in the clasp of the bracelet. It’s easy to take out with a pair of side cutters
Killer video brother! Thanks for sharing with me!
Thanks for watching
@@mbmmllc for sure bro! I love your channel!
Good one Jason you have shown me another way to refine gold and silver two thumbs
Great thanks!
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
Thanks! Glad you are experimenting on your own. It takes some practice, but you will get it!
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...
little iron is the spring inside the lock
thanks- interesting and usefull
Great Job Jason!
Thanks Eric
Earned a new subscriber here, very cool videos, thanks!
That's a very cool process 👍
Thanks
Very COOL....TY
This was very interesting.
Hi Jason. What temperature do you cupel gold? Does it matter how big of a button is expected? It is always the same temperature? Thank you
Awesome job. You've answered so many questions for us all, thank you.
Thanks! Glad you enjoyed it
Ditto
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
Très bonne fonte mon ami✨✨
Great video.
Great video anyone know if you could use this technique for electronic gold recovery?
very cool i have a3.9 oz bar i want to do this to thank you my friend great video
I heard it said once "make your profit when you buy fhe scrap" I'm sure its easier said than done. Thanks for sharing the video.
Good video keep them coming
Will do
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!
Hi,
What does it mean when you melt gold jewellery down and it all turns black rather than molds together?
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 👍🏼
Super interesting, I'd love a job at your company
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.
Could you use a cupel to separate tin & silver in high silver content solder? Where can you get the cupels and the cone mold you use? Thanks in advance
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?
Yep, that should work well
hi sir, thank you for your quality informations, i have a question, i got almost 20 kilo of gold dust and dust rocks n i ordered a 2kilo electric smelting melting gold furnace, the brand is podoy, from amazon. i wanna know of i should go easy on this machine as its cheap price or if i can go all the way with almost 20 kilo, like 1 kilo at the time
Good day, I want to know if this method will work for rose gold and bring it back to regular color gold. How long do you keep it melting for in the furnace.
Jason, that was awesome. I’ve always wondered about that. Thanks for doing that. Do you know how many watts or amps that furnace draws?
Thanks.
The smelting furnace is propane with forced air, so equivalent amps is hard to tell because electricity is not used.
EDIT: oh wait i just saw the electric furnace/kiln for cupelling
Once you've made buttons, do you separate the silver from the gold or sell them combined? Where do you sell it? Coin shops? Pawn brokers? Metal recycling yards? What's the process after the button? Thanks.
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
I was looking for a harmless metal instead of lead in a cupellation process. Thanks!
bismuth
Tanks a lot for this method. How much heat os necessary to melt the Bismuth in the crucible?
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.
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.
The hasp/latch on the bracelet likely had a small steel spring in it.
is there any risk for base metals like led or mismuth ti still be in the gold after this step?
Hello Jeff I'm curious what the noise was the firing up the kilm? Are you pushing air in?
Hey i really like yout smelting videos, i'm not from the U.S so i have a question, what does Matte means or technically what it is? Thanks for the information anyways, greetings from Colombia
Thanks Jason. Been struggling for a little while on getting this process down for myself. My biggest question after watching the video is, about how long did it take with the first cupel in this video to get the completed button? Trying to see if I'm not waiting long enough or if I'm doing something wrong.
Takes about 30 mins. Make sure the bead is geting oxygen, but staying hot enough. If you run it too cool the bead will keep freezing before the base metals are completely removed
Thanks it was a cool video but Even better it’s the value I was interested in so all my 14 k scrap leave it scrap till I have enough to trade for 24 for the long run👍
Jason, I was wondering what number cupel you use; I'm ordering a case from Legend but I'm not settled on the size. Thanks for all of your great videos.
It really depends on the amount of lead you want to absorb. I think I bough ones that can do like 65 grams and ones that can do 300 grams. Both are useful for different applications
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! 👍
Yep, this can be scaled up. It can be used to do kilos of gold with a big enough cupel
@@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.
@@mbmmllc I have 6+ kilos of sterling flatware here ready for a video. 😉
@@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.
Can you do this method with different gold or just 14k? And do you need them separate or can you do 10 to 18k?
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?
Great video. Did you remove the little spring steel part of the clasp?
Nope, put it all in the crucible and melt away. Cupelling will take care of the Fe
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!
Excellent! Any difference between Bi and Pb during cupellation?
The only difference i can tell is it seems the Bi takes a little bit longer to oxidize than the Pb. Have you tried Bi yet? Thoughts?
@@mbmmllc No, I haven't tried it yet but I plan to
When you’re “schmelting”😂
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
