Thanks for showing your craft. I’ve been collecting urban gold for 11 years, but haven’t got around to smelting it. Really like your S O2 gas refinement. Thank you so much for doing this.
Absolutely love seeing the real time colour changes with the SO2 precipitation. Can watch it a thousand times over and it never gets old. Cheers from down under 🍻
Sreetips, I remember the first time you used your wedding band as a demonstration for inquartation processes. Your wife is truly an angel and one of great faith. God bless you both. Your videos are such an educational and life lesson experience!
Sreetips. this happens to be , in my opinion your best video thus far. it was so good on so many levels from the educational content and value to the management of time and the quality of videography the way you demonstrated the importance of inquartation , the precipitation of the gold using first the SMB and then showing a stunning SO2 precipitation and taking a Dustin from the comments on removing the gas tube when it went clear..just everything all around was spot on and you should definitely be proud that your videos continue to progress and get better just like everyone should strive to achieve.. Personal progression. really ,really good video! keep up the great work and thank you very much for the class on precious metal refining. You really hit this one right out of the park! 10 out of 10
As a teacher, I can easily see a first year university chemistry student doing this experiment. I wouldn't do this with high school kids though. It's too much of a liability, because too many uneducated Christian parents would complain that's it's voodoo/woke learning.
One of my favourite channels. Shout out to you sir from myself over in Wales UK and may God bless you and your family for providing us with a decent TH-cam channel.
You see a difference in the wedding band, and the 6K gold, the low Karat gold turned brown almost as soon as the nitric acid touched it, the band stayed golden yellow. Seen you do this a time or 2 before this. It is still amazing
Wow! Just wow! Just when I thought you couldn't amaze me any more. You have got the whole process down to a tee and it is hypnotic how the gold ends up so pure and beautiful, well done again sir!
I think the inquartation has finally sunk in as long as you remember to melt the two metals together first. You said copper can be used as well, I'm going to assume the same 75% as you did with the sterling. Very informative and thank you Sreetips.
I've been watching your videos for a couple of months now, and I've gotten to where I usually know what you're going to do before you do it. I know they didn't have these videos when you started, so many thanks for sharing your hard-won knowledge. That was the shiniest most beautiful bar I've seen you make so far. I feel like I might be able to do it now, if I wanted to invest in the vent hood, all the beakers, the acids, the melting equipment, etc. I'm afraid of the upfront costs to getting started, that's for sure.
My take is that quartering au with ag is ideal. The demonstration between carat au Vs cu in the hno3 solution was amazing. Note: The carat au was unaffected but the cu finely separated into solution. The inquartation of 25% au with 75% ag cast as shot then boiled in the hno3 H20 solution several times resulted in three 9's au. Quite frankly it becomes obvious that low carat au is cast fairly often so it must do well. That said, I'm left wondering if graphite pour cubes shaped like 14 mm chess pieces are available or if you would need to cast using other methods. Probably 24 k kings, 18 k queen's, 14 k knights and bishops, and 10 k rooks would be interesting. Adding gems would be really fun. Cheers,✌️♥️👍 Kudos to the Mrs.'s
The experiment with your wedding ring was so kool. I love seeing the inquartations, precipitations and melts. SO2 gas precipitation is really stunning to see. Nice. 👍
We used to find gold in Goodwill jewelry jars all the time. But now we don’t even bother looking because, like you said, they’ve figured out how valuable GOLD really is. This trend will continue as people slowly turn away from printed paper notes, that have no value, and turn to the only true money: GOLD and silver. Then, we won’t be able to find it anymore.
That buddist necklace might be worth more on it's own. If it's a legitimate old hand-me-down necklace from an oriental origin, the piece might be an antique! My friend had a very similar thing with a 3D Vishnu on it made of 24k gold that was hundreds of years old, and it was worth like £5-6k, way more than it's weight in gold (about £3k of gold iirc).
Seeing that pile of mud in the crucible gave me the idea on how to safely store large amounts of gold. No thief in hell is going to give two craps about a few "mud" filled jars strew across your garage.
Don't feel obligated to answer, I know it's taboo to ask.. but as someone who loves a good bargain I'm dying to know how much Mrs. Sreetips was able to get all this great material for.
To those who ask why the senior chief doesn't start off by dissolving the 14K and 10K gold in aqua regia: Doing so would result in all of the silver turning into silver chloride, which requires a couple of messy reactions to refine back into silver, and the solution will contain base metals in addition to the precious metals. Inquartation, followed by a nitric acid boil, extracts the silver as silver nitrate, the base metals also go into solution, and only the precious metals remain as solids. Recovering the silver metal from the solution is a much less messy procedure.
I’m happy to see your channel growing man. I’ve been following you since the beginning. Back when you had a few hundred views and almost no comments other than a few questions. Plus you took care of the headset issue I noticed. Keep up the great work and I’ll always check out what you’re doin mister.
That was .9999 Pure Gold! Beautiful bar!...Where's mine! Lol 😂...And thanks for the Sulphuric purification after using the SMB twice...That's why that Ingot looked so bloody good...Well done...
Hello Mr sreetips. Seems to me that Mrs sreetips has work hard to get gold to your hobby. God truly blessing both of you. It is so nice to see. Hard woork and gods blessing realy pays out🌹🌹. Have a Nice day, and thank you for a nice clip. Arne 🇳🇴

Like the powerful bond of gold atoms, the fact that Mrs. Sreetips allows you to put your WEDDING band in ANY kind of ACID speaks volumes to the strength of your bond.
Another great refining sreetips! The aqua regia must feel weirdly heavy for that small amount of liquid. I imagine that the dissolved gold would just add such an unexpected amount of weight that it would be odd to handle. As usual, all the valuable information and steps were great to watch and hear you iterate. I learn so much every time I watch you do this, even when things go a little wrong.
I love this! I shared this video with my wife, to reignite her desire to go, "Urban Mining", at Estate Sales! Please don't boil your wedding ring....... again! I cringe every time you do that! 👍 Great and FANTASTIC CONTENT! NEVER GET TIRED OF WATCHING YOUR TH-cam VIDEOS! Wade
Most people don’t understand gold and silver. They believe, incorrectly, that paper dollars are more valuable than the metals. For those that do understand, a world of prosperity awaits.
that was cool to see and helpful. I wouldnt of risked my ring tho lol. Just goes to show you really know what youre doing and trust yourself and skills. I like it other then a little cleaning the ring was fine, did not expect that.
Hands down best content on yt my add/adhd is totally invested lol currently collecting scrap and karat gold also step dad was a jewler i have sweeps platninum gold many scrap pieces ect cant wait to execute this method of refinement
Excellent video every time I see you use your wedding band for example it's always interesting to think people still don't understand why you use silver outstanding video awesome content thank you for sharing six Stars brother
When you did the hydrochloric boil after the first aqua regia precipitation, what was coming out of the gold at that point to cause the little bit of color?
After you dissolve the silver and other metals from the enquarted gold alloy, are the gold pieces that remain spongy in texture or still hard and metallic?
Maybe a little, but the point of the experiment was to demonstrate that the high gold content of 14k gold alloy protects the silver, copper and zinc in that are in the 14k gold alloy. Also to demonstrate that if we want the nitric to penetrate and remove all the silver, copper and zinc, then we MUST add additional silver (or clean copper) to reduce the gold concentration down around 25% or 6k gold. Then, and only then, will the nitric be able to do its job of removing those base metals in preparation for refining the gold with Aqua Regia. Inquarting and parting with hot dilute nitric is a recovery process. Dissolving the gold with Aqua Regia is a refining process. Recovery and refining are two totally different processes.
If you do the gas bubbling process again, can you explain what is happening exactly? Besides that last bubbling process, I was super happy with this video with you explaining every step, thank you for a very great video. And I hope one day you can pour a full bar in that last size.
Hcl about 150ml per Troy ounce. Nitric, about 15ml to 18ml per Troy ounce. Sulfuric, ten drops. This is based on my experience refining maybe a thousand ounces of pure gold over the last thirteen years.
When the gold is refined all the down to right before precipitation, if you stop there would the gold stay in solution permanently? Without adding anything and just put the beaker on shelf would time precipitate the gold or come out of solution?
Yes, it should last indefinitely. But if it sits in the open for long enough then it could evaporate and form chloroauric acid crystals. To get the gold back out of these crystals I’d simply dissolve with some warm hydrochloric acid, filter out any junk, and drop the gold with SMB.
So interesting. Last question, when the gold is in solution right before you would go to precipitate does the solution weigh more from the dissolved gold?
Lead, no way. Nickel, possibly but the melt temp of nickel is so much higher than gold could cause problems. Copper is suitable. But I refine silver and the first step is to dissolve it in dilute nitric. So why not use sterling silver to inquart? It’s like refining gold and silver at the same time, killing two birds with one stone.
Love the video! I believe we will see gold/silver continue to fall through 2023 and then climb for the next 5 years or so. What do you think? Internet never forgets. So, I may be proven foolish with this post, but I did predict the $50 silver boom and it’s fall. Sadly some fought me on that. I hope they didn’t lose too much.

Amazing how watching you work the magic is so satisfying!
Great looking bar!
nice bar, has to be one of your best. love the ripples :)
Grateful you did that with the ring. I hadn't understood until I watched this video what inquarting was for.
When you did the hydrochloric boil after the first aqua regia precipitation, what was coming out of the gold at that point to cause the little bit of color?
May have been some gold going on solution due to a little excess nitric.
@6:20 What was that blue heart made of ? I waited for the resolution, but it wasn´t shown.
That was a blue topaz
I'm wondering if some sort of diffuser for the bubbles would make it more efficient?
No, it would quickly get clogged up with gold.
Man that gas is the way to go. Another beautiful bar sir, great job.
Hey just curious what do you do with your plastic/glass beads that maybe threaded ? Need sone for fishing lures n such.
That color change relation is awesome to watch
I would really love to buy a gram bar or something from you made by you sir. Thanks for sharing your knowledge and experience with us all.
Sreetips I'm curious if your ever nervous to make some sort of disasterous mistake and not be able to get the recovery? I'd be so so nervous!!
If you keep trying this with your ring, will the surface slightly purify similar to the native process to produce tombaga?
I’m not sure
I’ve learned so much from your videos, i hope to one day refine gold scrap i have been collecting
After you dissolve the silver and other metals from the enquarted gold alloy, are the gold pieces that remain spongy in texture or still hard and metallic?
They are metallic but fragile and break apart easily if crushed with a glass rod.
This is so very fascinating. Thank you.
That's by far the best looking gold bar you've done yet sreetips 👍
What kind of process is used to identify the potential valuable stuff in the field?
Experience. There’s no substitute for experience.
will some silver from the 14k ring be eaten away a little bit making the ring higher gold content on the outside surface?
Maybe a little, but the point of the experiment was to demonstrate that the high gold content of 14k gold alloy protects the silver, copper and zinc in that are in the 14k gold alloy. Also to demonstrate that if we want the nitric to penetrate and remove all the silver, copper and zinc, then we MUST add additional silver (or clean copper) to reduce the gold concentration down around 25% or 6k gold. Then, and only then, will the nitric be able to do its job of removing those base metals in preparation for refining the gold with Aqua Regia. Inquarting and parting with hot dilute nitric is a recovery process. Dissolving the gold with Aqua Regia is a refining process. Recovery and refining are two totally different processes.
If you do the gas bubbling process again, can you explain what is happening exactly? Besides that last bubbling process, I was super happy with this video with you explaining every step, thank you for a very great video.
And I hope one day you can pour a full bar in that last size.
I must admit, I’m not exactly sure how the reaction happens. That’s why I didn’t explain it. But it sure looks like magic.
How do you determine the correct amount of nitric, hydrochloric, and sulfuric you need for the aqua regia?
Hcl about 150ml per Troy ounce. Nitric, about 15ml to 18ml per Troy ounce. Sulfuric, ten drops. This is based on my experience refining maybe a thousand ounces of pure gold over the last thirteen years.
When the gold is refined all the down to right before precipitation, if you stop there would the gold stay in solution permanently? Without adding anything and just put the beaker on shelf would time precipitate the gold or come out of solution?
Yes, it should last indefinitely. But if it sits in the open for long enough then it could evaporate and form chloroauric acid crystals. To get the gold back out of these crystals I’d simply dissolve with some warm hydrochloric acid, filter out any junk, and drop the gold with SMB.
So interesting. Last question, when the gold is in solution right before you would go to precipitate does the solution weigh more from the dissolved gold?
@@markhutchins3643 yes, a volume of liquid with gold dissolved in it will weigh more than the same volume of liquid with no gold in it.
@@sreetips Thank you Sir for your time! Love the content! It’s really interesting
Hello If you don't have Sterling silver to melt with the gold carats Can you use Lead or nickel ingots instead???
Lead, no way. Nickel, possibly but the melt temp of nickel is so much higher than gold could cause problems. Copper is suitable. But I refine silver and the first step is to dissolve it in dilute nitric. So why not use sterling silver to inquart? It’s like refining gold and silver at the same time, killing two birds with one stone.
its always fun watching these videos
I love watching the silver melt under the open flame it's my favorite part.
Love the video! I believe we will see gold/silver continue to fall through 2023 and then climb for the next 5 years or so. What do you think? Internet never forgets. So, I may be proven foolish with this post, but I did predict the $50 silver boom and it’s fall. Sadly some fought me on that. I hope they didn’t lose too much.
I think making predictions is risky business. Especially if they’re about the future.
