@@williamfoote2888 Yes, it is about 20 degrees Celsius higher than gold. Also, the smaller gold pieces heat up quicker than the larger piece of copper wire.
I would love to see a video on the setup you have and all the safety equipment you use and wear.( Fume hood,chemical storage ,etc.) My wife and I have collected over 4 lbs of Gold filled scrap from thrift stores over the last two years (tip .go on senior's day to get 20 % off) and was thinking of processing it in the near future and would like to do it as safely as possible
Fume hood is a must. After that, I’d recommend doing a small batch, a hundred grams, to completion. To get a feel for it. Then scale up a little at a time. Four pounds is enough to do several small batches.
I know professional refiners don't value copper too much but I love it's color! The colors of copper's salts are very beautiful blues and greens. Great video!
A thought occurred to me, Sr. Chief....i looked up the melting points of both copper and silver....silver melts at 1763 F. Copper melts at 1984 F. I don't know how much Acetelyne or MAP gas costs out there, but the extra 200 degrees to melt copper every time you need to inquart might start to add up.
The specific heat of copper is higher than the specific heat of silver, however the amount of material we're looking at is so small that we're talking about a few more seconds of acetylene to melt the copper anyway.
Those blue shades are incredible. I love the pulsing during the boilings that has been happening the last couple videos during the nitric boil time lapses. It is reminiscent of heart beats.
I've been noticing that too and it's kind of interesting that it happens with the 6 carrot (25%) Nitric boils but not with hydrochloric or AR but only with the inquarted gold nitric boils which is kind of interesting and I wonder why that is
I feel like the gold crashing out of the solution would be a cool effect in a movie if shot with a macro or probe lens. 🤔 Looks like billowing clouds forming out of nothing. It's very satisfying to watch that part.
I’ve been hoarding scrap gold and silver for awhile now. I found your channel a couple of years ago and have been trying to learn everything I can from you. We are going to be moving soon, and when we do, I’ve already budgeted in a large shed and everything I need to. I’ve been wanting to refine my gold and have to stay on myself to wait until I have everything I need… thanks for another great video sir
You are welcome. Adding copper to my placer gold was something a friend suggested I do a few years ago, I thought he was nuts until he briefly explained inquarting. Fortunately, I wandered into your channel whist in search of a more thorough explanation and found not only that but much more. Thank you Sir!👍👍🤟
Hello sir, copper seems to be better indicator, if the nitric boil is clean, however nitric consumption is like 4x higher (I calculated it some time ago, I remember x3.5 or something). Also, clean silver is "byproduct" when using silver inquartation, so to disolve it separately is another amount of nitric. If clean gold is priority, copper definitely has advantages. If economy of process is priority, silver is way to go... That is my take from todays video. Thanks...
I’ve been a goldsmith 36 years refined my first through electrolysis. ( I was a novice at the time). Apprentice. I’ve relearned a lot from your knowledge of chemistry and safety . Your teaching a whole generation to be confident in skills instead of college debt.
Sreetips, for some visual variety, I’d like to see the precipitaion done in “reverse" if thats possible. Create a dilute SMB solution and add concentrated gold solution to dilute SMB. Would be neat to see done a few drops at a time from a pipette or dropper. Maybe do a small scale test to see if its vaible first. Thanks!
I'll like to see copper being used to inquart the gold from now on. I don't know why but the rose gold is beautiful and of course very little silver chloride to deal with 🙌🏻. Also i would suggest that you sumerge the ingots in diluted sulfuric acid to remove any left over borax (like you do sometimes), i know it may be not needed but just to be perfect 👌🏻. I love this channel!
Thanks for sharing, I can't find much sterling silver around here so I almost always use copper for inquarting or parting. I'm glad you shared another video on using copper.
Very good video! Changing over to copper inquartation or just trying? It looks like your gold refining waste beaker is accumulating some gold pour off. How long do you wait before refining the gold refining waste? Keep up the great content!
So cool to see different methods, the last one was awesome too! Let's hope Streetips will decide to show us inquartation with other metals in the future, witch one can make the job and witch one can't...I presume there is something about the difference of fusion point...Loved this 6K rose gold!
Wonderful video, Mr Sreetips! But everybody knows I'm the REAL Copper Inquarter! 😆 Let me give you some advice, good sir. When you do your nitric acid boils to remove base metals... for copper inquartations, measure out 4.2ml of nitric acid per gram of base metal and add a little more nitric acid for good measure. For 10k, you can use the 5.2542 constant multiplied by the weight of the karat gold to easily determine how much nitric acid in ml is required. For 14k, you can use the 7.3584 constant. Use this same amount of distilled water for your nitric acid dilution. Let the reaction progress for about 3-4 hours until there are absolutely zero fumes left. Then decant this base metal solution and rinse the gold well with distilled water followed by a distilled water boil. This distilled water boil with remove all remaining color deep within the gold. Rinse a few more times with distilled water then perform a second nitric acid boil. You will notice that this second nitric acid boil will produce zero fumes and zero color. Allow this second nitric acid boil to progress for a good 30 minutes for good measure, then decant and save this unreacted dilute nitric acid for a future refining. Then you can rinse the gold with distilled water a few times and perform another distilled water boil followed by a few final distilled water rinses. You can then proceed to dissolving the gold in aqua regia as usual. I have followed this procedure multiple times and it never fails and produces stunning looking gold. Again, great work, sir! And thank you for the wonderful content! Cheers! Copper Inquarter
In a previous video a year or two ago, I think I recall Sreetips saying it takes a lot more Nitric Acid to dissolve copper than the same volume of Silver. But in this video it was 6 doses the same as usual. Was the volume of Acid per dose higher?
I like this process because you can save your silver to process separately with less steps getting you the 2 best metals, clean gold and silver, using up a very easy to find one in copper.
@Sreetips It’s what I always use, only pure copper wire bare bright! The sterling silver I use up with making plain wedding bands and cuffs and jump rings! The down side is it eats up more HNO3! TBBW🐺
The problem with copper is how much more nitric acid it takes to get it into solution. It also has a tendency to take some gold into solution with it. Silver can also do the same trick although not nearly so much.
Now I wonder if using pure silver crystals will produce equally pure gold. Maybe these impurities come from the sterling silver and not from the silver itself?
Pure silver is colorless, like water. I’d lose the blue color indicator. Plus, pure silver crystal has already been through the silver cell. Be like taking a step in the wrong direction.
I absolutely love your videos!! Will you be using copper from now on since it gives you such good results? Or, was this just something to switch things up this time? Either way, your videos are fascinating to me. Thank you for doing them.
I don't know how much time it takes for the ice to cool down the solution or even if it's important, but I think crushing the ice would make it quicker or use chilled water instead
It looks like some of that copper somehow found it's way into the final product after all, that last melt took way longer than usually. Ingot look great tough.
Hey Kevin, but if you inquart with copper, you miss the chance to get rid of all the sterling silver who as a higher value once refined in crystals no ?
The sterling will find another path into the silver cell. I don't think this is an issue. You could say that inquarting with copper doesn't give the used nitric a chance to do double duty after it dissolves the base metals in the 6K gold, but I don't think that's a big issue. If you wanted to say that this method uses a bit more nitric, I think that's correct.
Hey Mr. Sree! Next time you get bored, could you do me a HUGE favor? 😅 If you could go through your videos and create playlists, that would be epicly helpful! A playlist for your gold filled, karat, e-waste, silver cell, and maybe a playlist for your fails for fun?, etc… OH! And a playlist of you equipment! Your fume hood is something i would like to have a better look at. I think you have videos on that already, but I’ve been struggling to find it! Scrolling through all your videos can get tiresome! Thanks in advance, and a BIG thanks for the plethora of content you’ve posted. You have taught me so much, that words can’t describe my gratitude.
hey sreetips! when i read the thumbnail of the video, i immediately went and read the wikipedia page for copper chloride. sure enough, it is soluble in hydrochloric acid, as i suspected. you taught me some chemistry :D
There’s a respectable amount of gold in that waste piggy bank jug. Lol… I love those refining videos. Not sure why, but seeing value come outta waste like that is fascinating! 💪💪
Copper has always been an excellent collector of precious metals. Easy to refine out also. That's how it's done in all the great copper smelters. Although in their large quantities they use electricity. Parting the precious as an end result.
@@Hossak Not surprising - Gold is worth about 7,500 times more than copper. It means that you can have a copper sample that is 99.987% pure copper and the rest being gold and the value for each of these two metals will be the same. You should look into the price of Plutonium: over $4 million per kilogram which is about 65 times more expensive than gold (on a weight basis)
Sorry I work in the mining industry and was just pointing out that when you sell your copper concentrate (5000 tonnes at a time) to a smelter, they generally pay over 98% for the gold content. I am sorry for the confusion.@@PetraKann
Ok, here's one for ya. What about making certain golds to spec? Black Hills gold 2nd and 3rd colors are 14k with copper for the 'red' gold and 14k with silver for the 'green' gold. True "Black Hills Gold' supposedly as to be mined from there to be certified as such, but the chemistry is still intersting!
@@sreetips Or perhaps like a surgeon implanting an artificial joint? Not the same, but has other value than just financial. Gods forbid I should say 'art' because I totally don't get art, but ...
27:37 Thanks SREETIPS! This was a new experience, and I loved it. The finish with this method was something else in the video; also, you mentioned it. A question comes to my mind: why always pour into graphite mold? Could you explain what's benefit to that? I mean, if the mold can hold the temperature after pouring, further or directly, you can melt gold and shake the mold to have a perfect bar, isn't it?
That's great! Now you can catch up on all your silver processing without adding a bunch of additional silver on top of what you already have.👍 You are going to use a lot more copper though.
I didn't even know you could inquart with copper. Also the first thing I thought once you had inquarted it was, oh rose gold....then you said it. Great viewing as always.
I ran out of feed stock shot. The cement silver is backing up on me something terrible. I need to get my furnace fire up and melt some impure silver shot.
Excellent video and the end product justified inquarting with copper. Check your melting dish, it looks dull and might need a reflux of borax and could be why the gold beads are sticking to the melt dish. You can clean the melt dish with melted borax, the more, the better , gathering up the small spattered gold beads into 1 larger bead for a few 1/10ths of a gram extra.
Looks like you used less SMB with Copper Inquartation, with about the same number acid solution seperations as Silver Inquartation and less expense. Great alternative if you're low on Silver too.❤
I still think it would be interesting to inquart the gold, but make a bar or button instead, then flatten it out as thin as possible with the rollers. Coil it into a spring and then see how it does with the hydrochloric acid. I think it would be quite fascinating to see if creating a larger surface for the acid to work on would separate the gold and silver faster. Or just to see what it looks like.
Darn it all! 🤣 Maybe if you have a nice hammer you could ust it to bang out your frustrations? Darn banks, supressing silver! *_BANG!_* (I keep lots too, its' GOT to break.) Darn YT making creators do stupid things! *_BANG! BANG!!_* Darn neighbors dog barking at the squirrels after I've been up till 4 a.m. waiting for this or that chemical reaction... *_Bang! Pow!_* 😁
@sreetips I see that now that I've finished watching. Knocks out the silver Chloride worries. I'm guessing the reason you use silver so often is because of your silver cells. Good job, brother.
I wonder when your going to do X-ray analysis to verify gold vs various methods. Would be interesting I think to see how much of what is left in the final product
Wow thanks for that , very impressive. I noticed you had a slightly carbonised softer flame on your oxy torch , on other occasions you have had an oxidised hard flame with quite a lot of smoke ! You may be losing some of your yield to burning? Just a throat , cheers
Off topic, but I've been going through your old videos trying to get a handle on shop setup requirements. Do you have a video on your glassware? Looking for minimum requirements, a nice setup and possibly the dream collection. Keep up the good work!
@@sreetips Most definitely a fume hood! Wouldn't even consider it otherwise. I'm trying to get a handle on price of entry into the hobby. Specifically I was interested in the glassware, since you seem to have a lot of various types and sizes of beakers, flasks, funnels, etc. I assume it's like most hobbies, the deeper you get the more you accumulate, but what do you consider the bare minimum needed to get started? Also are you picking them up at yard sales, Amazon or at the Lab Supply?
I buy my glassware on eBay. I had a chemistry lab in my basement when I was in 7th grade. This is more or less a carry-over into my adult life. I just bought the glassware as I needed it. You should be able to watch the videos and take notes. That’s what I did. But back then, there were no videos like mine to refer to.
Good sir. Where is the video of the refinements of the jewelers gold, the one that was cracking due to lead. I believe it was a sheet that he was trying to roll out. I can’t find it. Thank you! ❤
I really like the addition of clocks and timers to give context to the time lapse footage! Thanks Sreetips!
Man that blue color is something else
I love the new lighting! Watching that gold precipitate with the SMB under that light is magical.
MSB , on that first spoonful has always been my favorite part . Watching the cloud form and change 👌
Nice alternative to always having to deal with silver every time, well done !!
It's really cool to see the process with a different base metal. I was quite surprised at how difficult the copper looked when melting.

Awesome work Sreetips.
Great video it was brighter even as a melt. Awesome
Would believe the alloy crystal structure would rather need a bit more copper than silver but the results tells the truth.
It looks like the copper version makes it a little more resistant to melting but boy dam it looks good
Wow, been wondering when you'd try this. I saw Nile Red do this a few years back. So interesting to see how the process is different.
In a previous video a year or two ago, I think I recall Sreetips saying it takes a lot more Nitric Acid to dissolve copper than the same volume of Silver. But in this video it was 6 doses the same as usual.
Was the volume of Acid per dose higher?
It was six boils, about the usual (I've seen seven a couple of times), the amount of nitric in each boil was about double.
For this amount of gold 5 nitric boils would have done it using silver, maybe four.
I like this process because you can save your silver to process separately with less steps getting you the 2 best metals, clean gold and silver, using up a very easy to find one in copper.
The first step with silver is to dissolve it in nitric. So that’s why I use silver to inquart. Refining both metals at the same time.
Excellent video thank you 😊

In brewing and winemaking, we also use SMB. We use it to kill wild yeast a couple days prior to pitching the yeast of choice.
Yes, SMB can be purchased in bulk from beer and wine making suppliers.

I usually speed the melt sequences to save time. I left them at normal speed for this video.
Looked very clean after the first refining pass. Probably was 3 9s already
That’s a testament to how good inquarting with silver and parting with nitric is at cleaning the gold.
Hey Kevin, but if you inquart with copper, you miss the chance to get rid of all the sterling silver who as a higher value once refined in crystals no ?
He has silver coming out of his ears, and has said so in a few videos.

I noticed you haven’t been showing your silver cell lately. I was wondering why?
I ran out of feed stock shot. The cement silver is backing up on me something terrible. I need to get my furnace fire up and melt some impure silver shot.
I do mine in my stock pot with copper and just collect the residue later after the base metals have been removed. But i am not in a rush.
Excellent video and the end product justified inquarting with copper. Check your melting dish, it looks dull and might need a reflux of borax and could be why the gold beads are sticking to the melt dish. You can clean the melt dish with melted borax, the more, the better , gathering up the small spattered gold beads into 1 larger bead for a few 1/10ths of a gram extra.
Too much borax and I’ll glue the gold ingot into the graphite mold. Have to break it to get it out.
Nice one! Is this the way forward?
Looks like you used less SMB with Copper Inquartation, with about the same number acid solution seperations as Silver Inquartation and less expense. Great alternative if you're low on Silver too.❤
I still think it would be interesting to inquart the gold, but make a bar or button instead, then flatten it out as thin as possible with the rollers. Coil it into a spring and then see how it does with the hydrochloric acid.
I think it would be quite fascinating to see if creating a larger surface for the acid to work on would separate the gold and silver faster. Or just to see what it looks like.
I tried that once. It was so tough that I could get it to feed through the rollers.
Darn it all! 🤣 Maybe if you have a nice hammer you could ust it to bang out your frustrations?
Darn banks, supressing silver! *_BANG!_* (I keep lots too, its' GOT to break.)
Darn YT making creators do stupid things! *_BANG! BANG!!_*
Darn neighbors dog barking at the squirrels after I've been up till 4 a.m. waiting for this or that chemical reaction... *_Bang! Pow!_*
😁
I’d rather let the chemicals do all that work for me.
So satisfying 😮
That seemed like a much cleaner process.
The copper seems to work better than silver.
@sreetips I see that now that I've finished watching. Knocks out the silver Chloride worries. I'm guessing the reason you use silver so often is because of your silver cells. Good job, brother.
Correct
I wonder when your going to do X-ray analysis to verify gold vs various methods. Would be interesting I think to see how much of what is left in the final product
Gold in solution never gets old
Definitely a more refined, purer Gold Bar as a final result. 👌
Is there a time limit that gold can be held in aqua Regia before it must be precipitated out? ❤ Always interesting.
None that I know of. It can be stored in solution or even evaporated to crystals of gold chloride and stored indefinitely.
Wow thanks for that , very impressive. I noticed you had a slightly carbonised softer flame on your oxy torch , on other occasions you have had an oxidised hard flame with quite a lot of smoke ! You may be losing some of your yield to burning? Just a throat , cheers
Off topic, but I've been going through your old videos trying to get a handle on shop setup requirements. Do you have a video on your glassware? Looking for minimum requirements, a nice setup and possibly the dream collection. Keep up the good work!
Fume hood first. No way to safely do these reactions without one.
@@sreetips Most definitely a fume hood! Wouldn't even consider it otherwise.
I'm trying to get a handle on price of entry into the hobby. Specifically I was interested in the glassware, since you seem to have a lot of various types and sizes of beakers, flasks, funnels, etc. I assume it's like most hobbies, the deeper you get the more you accumulate, but what do you consider the bare minimum needed to get started?
Also are you picking them up at yard sales, Amazon or at the Lab Supply?
I buy my glassware on eBay. I had a chemistry lab in my basement when I was in 7th grade. This is more or less a carry-over into my adult life. I just bought the glassware as I needed it. You should be able to watch the videos and take notes. That’s what I did. But back then, there were no videos like mine to refer to.
@@sreetips I definitely appreciate the videos. I'll start taking notes. Thanks.
Looks like its a lot cleaner but it seems like it took longer to melt down..👍🏻👍🏻
I slowed the video down on this one.
Gold is the best investment.
Gold is not an investment. Gold is money. It’s a store of value.
When you make the timelapse, put on like sound you record in the shop, the fumehood, the compressor and so.
Have the sound go at normal speed.
Excellent suggestion. Thank you
Whoa! Is this like an evolutionary advancement in gold refining?
No, I’ve done it before. But I’ll still use silver going forward because I refine silver also.
Good sir.
Where is the video of the refinements of the jewelers gold, the one that was cracking due to lead. I believe it was a sheet that he was trying to roll out. I can’t find it.
Thank you! ❤
I can’t remember
@@sreetips
Okay. Thank you good sir. I’ll keep looking. Thank you for all the videos and information you post up. By far, yours are the best! ❤️🔥
