Big thanks to Mrs Sreetips for finding all the jewelry that keeps Mr Sreetips busy on this channel
Mrs. Sreetips must have a keen eye to always keep you well-stocked with scrap to refine! The diamond was a nice bonus as well! Excellent video as always!
I saw your notification of an upload and then realized you must've been burning the midnight oil. I dig watching this process also. Thank you for staying up even later to get this uploaded for our viewing pleasure.
Another thank you is due to Mrs. sreetips for all the legwork and windshield time she must go through to make this video possible. 😊
Excellent. She’d probably say, “why are you thanking me, this is what I love to do!” She’s up at 3am, gone by 5:30, before the sun comes up, looking for scrap gold.
@@sreetips dedicated gal you got there
It’s a passion and an obsession all rolled into one.
@@sreetips
I totally get it😉👍
Glad I couldn’t sleep due to a cold. I have several ounces to process myself but am too sick to do it. This will help me while I’m getting better!
Get well soon, sir. 🙏
quick question, when the nitric acid is added, what is the gas given off?
It sure looks wicked, doesn't it? Like the same effect from every evil wizard in every disney movie...

That’s a really interesting and nice looking diamond.
I love watching the inquarting process and purification afterwards.
“Looks like coffee beans”, the most valuable coffee beans that I ever seen. Nice 👍🏻
That satin shimmer of the 6k gold is always awesome to see.
Sreetips wife: honey where’s the sterling milk saucers and dish
Sree: hands her gold 😂
16:20 we all need a timelapse of these bars dissolving 🙏🏻
Bloke, It's a good afternoon when I see you uploaded again, thank you. i love your content.
I'm doing a lot of research on melting metals. I'm going to learn as much as I can at first, learn what it takes to do it as far as equipment, and safety always comes first. It's going to take some time but I'm going to do it thank you
I love watching you make electrum (or as close as you get to it)
You saw that? ticking the fuse made the amps jump. Those type of fuseholders are notorious bad contact things. You should really check your Amps limiter on the power supply, it should be at max with the fuse in line. Fuses don't exactly pop at the rated Amps, there are graphs with time/amps pop point. Probably best to use a Fast (F) fuse. Means a thin wire and not a coil fuse.
I noticed your silver jar looks a lot like our old coffee percolator. Without its handle. lol
And it is. The stainless handle got so many drips of dilute nitric [50 x 50, 60 x 40, whatever ratio is achieved with a casual addition, that he had to deband it. Even the clear plastic handle suffered chemical dissolution to some extent. As he says, these chemicals can cause death. All of them cause problems to the fume hood and whatever space it vents to. Edited for addition and spelling.
Good work team
As much as I would love to see a Mrs Sreetips “how to scrap shopping” video, I don’t think she would give away all of her secrets.
My favorite videos. Gold recovery and refining 🐉 Thank you for sharing with us Sreetips 🤠 God Bless 🙏
Awesome video Kevin. Still reading and learning this process.
If you refine your gold but find that their is still some copper left behind, can you eliminate the copper with aqua Regis? Or do you have to return to inquarting with silver?
No need to return to go to inquarting in the case of a bit of copper remaining, the silver content while low is still able to be parted with Nitric.
Aqua regia should only be used at the last step to dissolve the gold as it also dissolves many other things that might be present hence the reason for multiple refinings with a variety of methods.
Edited to add the answer to your question. Copper will dissolve in aqua regia and it will be dropped out of solution with the addition of a little sulfuric acid just like the lead.
btw lead is essentially radioactive materials destination to some extent check the Half-Life products listings and tables to see what path some take.
@@CothranMike Thanks for the input Mike. I’ll return to aqua Regia and go through this process 2 or 3 times, which should turn out well
If there’s copper in there then the solution should turn green. That’s why I alway do a second refining. It really cleans the gold up. And that should eliminate any stubborn copper.
@@sreetips Thanks Kevin that is helpful. Now I just have to set aside some time to complete the process
What's the fun in buying gold jewelry & selling it as is, when you can take it & refine it !! 😊 😊
Glad to see you're back Sreetips!
Its good that your spouse can enjoy your hobby with you
I just love how the nitric acid reacts to the 6k gold even before you add it to the heat lol 😄
Check Land of Chem @ Qasr El Sagha, Palace of the goldsmith. Seven chambers for seven refinements. Septic means sevenfold. Inquarted gold stripped of silver and base metals looks like septic sludge. Thanks for your brilliant presentations Mr Sreetips.
You do a great job on your video's. Thanks
Thank you
100% enjoy the process
Thank you
So I'll be watching a lot of your videos
Thank you
That Tiffany piece is very nice and should sell quickly. Diamonds on the other hand may have peaked a while ago. It’s beautifully faceted and bright. I could be wrong but, they seem to have become more valuable when they’re used as a cutting tools.
Conanthelibrarian antique diamonds, although as I say that I keep thinking antique diamonds my God aren't they all antiques, should be worth more.
Edit for extras:
The arbitrary value of the diamond has been manipulated for centuries. Industrial diamonds on the other hand are frequently harder. Black diamonds being some of the very hardest we've ever come across, and the reason we came up with cubic boron nitrate or CBN. I have both a small square chipped from a larger rectangle and a whole 4mm x 120 mm rod of the stuff from the 50's.
Oh very interesting. So the black diamonds are the ones used for industrial uses?
My wife loves jewelry and of coarse diamonds. All gemstones for that matter. We watched several programs on diamonds. It was very interesting. They were saying that we and I mean we as humans can
duplicate an all but perfect diamonds and that people were paying the same amount as actual diamonds. Also that the earth has produced many more than we once thought. But I’m by no means knowledgeable
about gemstones. I love your channel. So please keep up the great content. And thank you for answering me.
Can you explain how much you spend on purchasing the scrap gold? I’m curious about how she finds these items and how much she pays for it.
Thank you for great videos
I seen one charge for thirty seven hundred, another for six. She got up at 3am this morning. She left about 5:30 for the flea market. She will arrive at an estate sale three hours early just so she can be first in line, because if you wait, all the gold will be gone. This is what she does. It’s her “job” and she tries to get me to go, but I can’t sit there doing nothing for hours, waiting for the sellers to show up. Buying jewelry at local shops and sales is what she thrives on. Almost to a fault, it’s her passion and obsession all rolled into one. I hate digging through dead people’s stuff trying to find overlooked scrap gold. But I have gone with her and found thousands of dollars worth of gold, for just a few hundred. Without her, I couldn’t do this. I’d probably be punching a time clock at Home Depot right now. She’s the best thing that ever happened to me in life. She loves finding good jewelry deals, I don’t care for it much. I love refining, she can’t stand it. We are the perfect match.
You could tell you had a lot of copper by the green flame when you alloyed. I was the most green flame I saw
As always a pleasure watching your channel thank you sir for sharing this with us six stars
sreetips, send me all your gold and silver, now. Great video! I LOOOVE gooldddd!
Jedi mind trick!
I'd love to see an experiment where you dry and re-weigh the remaining metal between each nitric boil. It would be fascinating to see how much base metal is dissolved at each step.
Sorry, probably won’t do it due to the work involved.
@@sreetips would it be that hard? You already rinse the gold and then drain off most of the excess liquid after each boil, so I had thought it might just have been a case of leaving the metal on the hot plate for 5 minutes or so after to evaporate most of the rest.
I love your videos. My daughter has a degree in chemistry from the University of Massachusetts maybe I can get her to teach me how to do this. The only problem is she lives in Oregon.
You don’t need to be a chemist to refine precious metals. But it helps if you do.
Love the channel, I thought maybe I had a chance to purchase some 3 9s gold dust from Australia to support you 😅
Imagine a classroom filled with all of your followers and pupils ?
Even if it is not your purpose.
😉
haha i just bought some sterling baby cups like the ones you just used to inquart with i was racking my brain ab if i should cut them up first before i get them in the melt dish then i thought "what would sreetips do" and then you post this video thanks for all you do and teach us kevin
~Austin
Excellent
@Sreetips, when pouring the melted alloy into the bucket of water, it looks like there may be wasted material splattering over the sides, or perhaps its just the torch light reflecting off the water. Have you ever swept the floors of your shop/lab and processed the dirt and debris to see if it contains any gold or silver like you've done with the jewelers waste?
Yes
I just had an interesting thought, what if when you did an inquartation like this you were to weigh the gold/silver at different intervals while doing the nitric boils? I wonder how close to your estimated yield you would be able to measure, especially at the point you feel like you're done removing the silver. I know it's an estimate of course and you do lose some in the refining which you recover later but I think it could be interesting to see how much of the silver and other base metals are coming out in the nitric.
We ❤ your videos! Informative and entertaining!
Thank you!
Gooood afternoon from central Florida! Hope everyone has a great afternoon!
Gooood afternoon!
There is no "probable" about still pulling silver when you are pulling copper from the gold. As you inquarted with sterling silver, there should be a lot more silver than copper in there. Taking into account the relative reactivity of silver and copper, you will still be pulling silver after you have finished pulling copper.
I love your content Keith. You inspired me to start scrapping as a hobby. Out of curiosity, do you have a buying guide for scrap jewellery? I have been scrapping electronics and want to up mu game 😁
We’ve been doing this for decades. I can almost tell by looking whether a piece is gold plated, or solid karat gold. It due to the years of experience looking at tens of thousand of pieces over the years. There’s no substitutes for experience.
You experience is unquestionable 😁. I am keen to learn where you get the scrap jewellery from and how much would you expect to pay so that you turn a profit. I know the difference between 18k & 12k etc, but do you have a formula to help you work out the cost?
I try to pay 80%, but sometimes Mrs sreetips gets it for much less at garage sales. I think she gave about five or six grand for this lot.
@@sreetips that’s helpful, thank you sir. The cost of nitric in the UK is about 4 times that of the US with lots of statutory limitations to purchase and really cuts any potential margins. I guess that this sector is getting harder to get bargain gold scrap because a lot of people are getting into scrapping and refining. I know you’re a busy man, so I’m much obliged for you taking the time to answer my questions.
Would love a meticulous breakdown of all your costs for a typical refining. From the acid, propane, acetylene, all the way down to the electricity consumption of the stovetop burner.
Less than a hundred bucks, not counting the metal.
When you ship that diamond, make sure it can't rattle around in the vial, they are fairly brittle even though they are very hard, and you know how the mail gets handled.
Ok
Will you be selling your bags of stones? I'm an amateur jewelry and I'm always looking for practice stones. I always enjoy your videos.
I tried once. List for five grand. There’s about four pounds. But it was too high and nobody wanted them. So I just keep them.
Ever think of splitting them up? That's about 1800 gm or 180gm for $500, or for novelty buys, 90mg for $250, maybe around christmas for gifts for that hard to shop for person 🤣
I saw a recent refinement video where a fellow refined a large chunk of impure gold by dissolving it directly into aqua-regia, then using the stump out to precipitate the gold. What's the down-side of using this much-simplified approach? Thanks.
He does both procedures actually. Usually what he has on hand and or the quality of materials.
I think he used the stump put method for stuff that had a lot of impurities and plastics but I honestly don't remember the reason.
Dirty solution. Recovery of the gold first (inquart and part with nitric), then refining with aqua regia is the proper way to do it. The contaminants will hold gold and create a loss.
I LOVE THAT CROSS HOW MUTCH IS IT
LOL
Try putting a wet piece of wood in the water when your pour your shots the will be flattened off the board
that diamond is a nice bonus, a couple of month ago i also had one about the same size, like half a carat. but then destiny hit and i dropped it, it fell into the gap between the wall and the baseboard, and down the floor. it barely fit but it had to fall down there 😂.
The jewelry repair shop that I worked at for four years used to eat stuff like that, never to be seen again.
Great video
Boom !! 💥
Bang!
Awsome as always sir
hi sir. Question regarding your nitric boils - would it not be feasible to perhaps do the maths on exactly how much nitric is technically needed to dissolve the quantity of sterling you use? You quantify the amount at the start for the inquartation process, does it not stand to reason one could calculate, chemically & mathematically how much nitric would indeed be needed to strip the alloys off the gold? I understand that calc might not necessarily change your process, ie. multiple nitric boils, but it could give insight on quantities for the purpose of mitigating the risk of having to manage excess nitric usage. Surely there are constants available stating how many mils of nitric are needed to dissolve x-quantity of sterling, no? Thanks for the vids, really enjoy learning from you and watching you do these refinings. ciao, A.
It will always be different due to the metals in the karat gold. I just go by the color and it’s served me well for the last thirteen years.
What do you do with all the stones like the amethyst? I would love to get some stones from you.
He sells them on his Ebay
Save them and sell them
Hope you see this question Sreetips...
When inquarting gold with silver, does it have to be sterling pieces?? Can you use you cemented silver? I remember?/ thought? you said in the past you have pallets of 5 gal buckets of cemented silver....
Thanks in advance!
Not recommended. PGMs will tend to build up in the cement silver if it’s used over and over. Then cause problems in the silver cell,
So why add the silver before removing the base metals? Would it not work without having to add all that silver?
No, the extra silver enables the nitric to penetrate.
Won't the bars get consumed slower due to the reduced surface area compared to the shot?
The shot presents more surface area and will dissolve faster than the bars.
When rinsing the tall beaker for the nitric acid boils, dont you need to be worried about the distlled water temperature? I kmow there's some kind kind of glassware specs about heat and cool, so i guess those beakers are safe? Are all beakers?
Borosilicate
@@sreetips You sir are awesome. Thank you! Safe cause of the type, got it. like Pyrex etc. edit: i did also just read more and I'll be very careful, gotta know exactly what to get, because Pyrex (although wouldn't use it for this, its not a good brand to use as the example today) Pyrex has changed through the years so that product line may or may not be good for extreme temps. buyer beware.
16:30 Won't they take a lot longer? The surface area of the small pieces is extremely high while the surface area of the bars is very low in comparison. I would think it will take a lot longer.
The bars will take longer.
Does Mrs. Streettips have ANY jewelry left???
Yes
Can you tell me the variations of gold sold. I think I have two or three. (1) Gold filled, (2) gold plated, and ((3)solid gold for example 18k is 20 grams weight= 75% solid gold and 25% base metals.). Does the third have a specific name or is it still gold filled? Are there more variations to buying au other than those 3? Ty sir
18k is 75% pure gold is called “karat gold”
Your wife is awesome . My lady couldn't be less interested in computer technology. Do you do gem certification on decent sized diamonds. So you would send or bring it to somewhere like the GIA so you can get a more detailed answer to its size and quality the 4 c's.
I’m not certified. But I’ve seen enough at the jewelry repair shop that I worked at.
592 👍's up sreetips thank you for sharing 🤗
Do you still ultrasonic clean the scrap gold first, or is fire enough of a purifying agent?
I’ve used ultrasonic to clean gold filled, but I don’t use it on karat scrap.
I would like to see you do a water density to one of your pure gold ingots that you refine to 999.9 pure
Mr. Sreetips, does your chapel have a filter for the produced fumes or is it ok for them to just go into the atmosphere considering you have a chimney thta is tall enough? Congrats on the content, by the way. I haven't been missing 1 single video. Keep up the good work.
Properly speaking fume Hood and the dilution of ambient air with the nitrogen dioxide should take care of it however filtering media are available for almost any reaction product. Consult a licensed chemical technician as I am not one.
Thanks @@CothranMike , you gave me all information I needed.
The fumes exhaust into the air outside my work area. I’m not a professional refiner. I don’t work on others material, only stuff my wife and I find at local sales. The exhaust from the cars on the highway do much greater harm than my occasional chemistry experiments.
Thank you, @@sreetips , for the attention. I had already thought the amount of fumes produced wouldn't be a problem if released on open area, just wasn't sure about it.
As a physicist, I love your content. Congrats again.
Thank you!
Does mrs Sreetips ever pay over spot for the gold content, of gold jewelry/scrap?
Yes
I can't wait to see the yield of the 6L silver cell...
Yes sreetips it looks like blonde roast coffee.
Because there is silver in it and you reuse that for silver shot for the anode basket correct?
Correct
I still have 3 kg of clean gf scrap. I plan on shipping this week. I'd just as soon send it to you as my refiner if you're interested let me know. It's mostly watch cases and band tops I get from my watch repair shop.
Sreetips has said he doesn’t do toll refining for people before, but Omegageek64 does. Omegageek has his email address in the description of his videos I believe.
@@TroubledOnePaydirt ^^^^^ this
I’m sorry but I don’t refine other peoples material. I used to recommend other refiners, but even that can be troublesome. It’s my hobby so I prefer to keep it simple. Doing others material is too much like work.
@@sreetips I wasn't wanting you to refine it for me.
I was just wondering if you wanted to possibly buy it. All the steel and other non metal parts have been removed so a lot of the work to get it ready to refine has already been done.
You've been busy? Is there a Streetips Junior on the way?
Hope not
When you get nitric do you have a favorite brand or maker?
Not really. Any chemical supply will have it. Technical grade (purity uncertified) is perfectly fine for refining.
God bless you
4oz 😮 That’s quite a haul
Dear seartips i see you do not add the final few acid boils to the sterling silver also i see there is some sediments in the flask labeled used nitric acid.
I was wondering if the sediment is gold, and if so do you recover and refine it seperately...?
Thanks
Yes, I’ll get it out some day. Maybe when I retire.
@@sreetips I am trying to refine some gold I have myself, this was my first attempt, I made a foolish mistake of inquarting with pure silver and no copper.
As the pure silver goes into nitric the solution stays colourless and after the 2-3rd leeching it became very difficult to see if the nitric was even penetrating the gold, the NO2 fumes were negligible.
Also i have a single piece I am trying to refine, I had approx 3gm 99.5 fine gold that I inquarted with close to 8.5gm pure silver, another mistake I did(I guess) is I did not melt it into shot but tried to refine it as a single piece. I have an ingot close to 11.5gm, is it to big for parting...?
Also one last question does the concentration of acid has any influence on the process the nitric acid I use seems fairly old, I always need to heat it up before any reaction takes place, unlike your videos where the reaction starts as soon as you add the acid...
Thanks for all the help.
Warm regards.
Adding heat always increases nitric reaction. You gained experience.
@@sreetips on the brighter side sure I did...
Thank a lot....:)
@@sreetips I did try to refine my gold again today this time inquarting with copper and small size pieces, approx 2gm a piece this time.
It was all going well and I was in my 4-5 leaching cycle but my hot plate broke down...:(
I was able to achieve close to 98% fine gold this time.... I'm very happy with the results...
I was wondering if I can continue with parting on the same pieces...?
Does nitric acid act on such high purity gold left overnight...?
Or do I need to inquart the gold again and start over...?
Is it worth it to buy up silver plated silverware as opposed to full sterling silverware?
No
Love your content as always! Is it possible to mathematically predict how much nitric acid you'll need to pull the silver and base metals out of a known quantity of 6k gold?
Probably, but I’ve never taken the time to figure it. The copper makes a wonderful color indicator that lets me know when the nitric boils are complete.
What are most of the base metals that are in the 6k gold? There's silver and copper which is most of it, would the rest be metals like zinc, iron?
Karat gold is usually gold, silver, copper zinc
@@sreetipsThank you for the response, glad I was in the ballpark.

Hello Mrs and Mr Sreetips 🌷🌷
So now has your wife shopping some gold fore you Sir...I bet she is a master to get the price down also so both of you get a profit. But the price on many sales are maybe low all ready 🌷🌷
God bless you 🌺
She’s the best thing that’s ever happened to me Arne.
@@sreetips That can i also se Sir. Have a lovely day both of you Sreetips ❤️
You too Arne. It’s good to hear the kindness in your posts
@@sreetipsYou welcome Sir 🌺
Is it okay to mix approximately 1part gold (18k) and approx 3 parts sterling (925) when melting before I nitric acid? Or have I just used too much sterling? Before I use nitric acid.Still learning. Thankyou
I use weight of 18k scrap times 1.9 equals proper amount of sterling
Thankyou
Hi @Sreetips I just subscribed to your channel I'm all new to your process. But are you actually making real gold and silver bars? If you are selling Gold and Silver bullion bars how do you test for purity that is it 999.9? I have loads more questions thanks
Most all of your questions can be answered by going back to the very beginning of his videos they're at his video channel under the name video
I’m working with real gold and silver. I send my gold to a big refiner. They check it with xrf to determine pay out. Comes back theee nines every time. I’ve had the silver analyzed via fire assay. Comes beck greater than three nines.
WHY MIX STERLING SILVER WITH GOLD?
So the nitric can penetrate
Nice
Do you ever have molten inquarted gold splatter out of the water when you pour it into the large aluminum pot?
Yes
Hi I'm from South Africa and when I do my nitric boil I get Grey powder along with my gold foils not sure how to get rid of it can you help
Seems like you're either doing gold-plated or heavy gold plated materials this is where you need to start your research online
Probably had some gold plated stuff in there.
How much difference would it make if you inquarted the gold down to 4 or 5 K? Would it pull the silver out faster, with less nitric? Just curious.
Simple answer no, long complicated answer no thank you today, been answering other people's questions on other channels for way too long today and I'm tired.
There’s a “Goldie locks” range. Too much silver and the gold crumbles to a powder and separating the silver more difficult. Too little silver and the nitric can’t penetrate fully.
Thanks for the info@@sreetips
If you would cut the brown gold. Would it be brown inside or would it have a gold colour inside?😅
It will look just like it does on the outside. It’s got a microscopic honeycomb structure inside as the nitric penetrates to the core of each piece.
One day, I would like to do this. If the jewelry resale venture doesn't work out, this would be a feasible option.
You could write in big letters the formula for all of your reagents so it comes through on the video.
I don’t know the formulas
@@sreetips I meant you could just write the reagents chemical formulas on the reagent bottles so the cameras could see them.
im curious, the sale price of the material you refine aside unless you are ok with saying how much was paid for a given volume of material for refining, per ozt how much does it cost to refine 1ozt gold in terms of chemical expense electricity etc. im mostly curious how much you have to spend on top of the purchase price to refine to get an actual price on the refining for contrast against the value of the refined product
I don’t keep track because I’m not too concerned with trying to resell the metal when I’m done. These metals are my savings. They go into my treasury. But I’d guess that refining this particular batch, not counting the metal, would be less than a hundred bucks easy, probably closer to fifty.
@@sreetips yeah i wasnt asking for resale estimates or the like cause i was just wanting a ballpark idea of $s spent on the chems
I've been meaning to ask, what do you do with the silver slimes?
Save em for later
Hi Sreetips, I was just wondering… with all your refining (especially with the silver cells), with all the accumulated copper solutions, do you ever refine the copper back out into bars for re-use? I’m sure you did use angle iron to get it out? Is there much value in it?
And can’t wait to see the harvest on the large silver cell 😊
Think sreetips has mentioned its not worth doing.. although for content, I'd like to see a sreetips copper bar for fun
@@MartinTreadgold I was thinking he must have tonnes of it by now lol
@@jameslangridge5878 nordic gold smelt
@@MartinTreadgold I agree on the copper bar. I'd personally love to see one poured and stamped, and I'd actually buy it as a nice souvenir/paperweight. There's no way I could afford a 5ozt silver crystal bar, let alone one of his 24K bars, but I'd happily trade him a $20 bill for a shiny stamped copper bar. Chip in on a jug of nitric acid, so to speak.
noob question: how to you know something is 18k or 10k ? feel ? stamp? squishiness? ty ♥
The stamp, but the stamp is not always accurate. Thieves will stamp gold plated
What size of a tank setup do you have for your gasses?
I use a two liter flask to generate gas
@@sreetips thank you.
I see in alot of your videos that you go through a good amount of sterling.
If you ever come across some tuttle sterling, older stamps are with a crescent and a pine tree. If so I would be more then happy to purchase it from you. Thanks again for all the knowledge.
Do you ever sell the silver from the anode basket?
No,
@@sreetips Thank you sir, I really enjoy the videos and have learned so much from you, so thank you again
Why not melt all the gold together, pour a small amount into shot and test it to determine how much silver to inquart. Instead of checking each piece?
That’s an extra step
Do you recover the Cu or scrap it?
Toss it. It’s useful in refining silver. But after that it’s waste. Clean copper for refining is cheap and plentiful.
