It does not matter how many times you watch, you always pick up something new from your commentary. Fantastic stuff and what a beautiful bar at the end :)
I like the addition of the clock because it keeps me from asking stupid questions like “how long does this or that take. I also like watching the stump out work. If you put 10 minutes worth of that in 1 video, I’d watch it for ASMR purposes ❤
Do you think the 2nd filter step could also have been skipped using the ice and beaker for the next reaction? I do like seeing the gold after the hydrochloric boil as it goes from dark chocolate cake to milk chocolate sponge. The gold looked fabulous after the 2nd refining. Love your work as usual my friend..👍
You are welcome. Always a treat to see your latest project produce another spectacular result, and getting there is more than half the fun. Thank you Sir!👍👍🤟
The little white flame looking stuff on the bottom of the beaker when SMB is being added, is really neat to watch. Fascinating, absolutely fascinating.
Even though I totally understand the chemistry involved, I'm still fascinated by the colour of the solution because I know there's a metal in there, but it's been *dissolved* and still has the colour I'd expect it to.
I'd say that about 50% of the appeal to these videos is the rinsing...THE RINSING!, and the impeccable hygiene in general. Nice bar, by the way, I want to sink my teeth into it.
the first smb precipitation when you first start to let it settle after stirring looks like some sort of pumpkin cider or something, kinda scary how apetizing some of this stuff can look considering the chemicals involved
I've been bed bound due to health issues and I love your videos. My only complaint is that you don't post more often, but I understand it's a hobby and I'm thankful for what we get!
The fume hood is good for human safety but also because nitric fumes will rust literally every piece of steel in your workshop, sink, pipes, etc. That stuff is really high on the corrosive scale. Also please don’t dump it down the sink or toilet, into the yard, sewer etc… Be like streetips and treat your waste properly. 👍🏻
Thank you so much for all your hard work,but I can’t help but when you add sulfuric to drop lead I wonder if you could get a surplus nitric bye trying to dissolve lead again .".
The bar came out really good, given that you even tried to save on effort at some stages. You seem to be really optimizing the process both in terms of labor reduction and the quality increase!
That's one good looking Gold Bar... @sreetips why don't you show the stannous test after precipitation with SMB.. Just to see what's left in solution.. Any orange or green
6:06: Completely untrue. It doesn't take any longer, and the nitric acid can still penetrate the inquarted gold just as well. The reason the nitric acid appears to be weak and take longer to dissolve the base metals is because you didn't add enough nitric acid to begin with. Please try my method on one of your future videos. Measure the amount of nitric acid required to dissolve all base metals in one go and add a little more for good measure. For 10k gold inquarted with sterling silver you can use the 3.4506 constant multiplied by the weight in grams of the karat gold to determine how much nitric acid in ml you need to dissolve all the base metals. For 14k gold you can use the 3.7512 constant. For 18k gold you can use the 4.05 constant. After around 3-4 hours, there will be zero fumes left in the beaker. At that point, decant the base metal solution as usual then rinse well with several distilled water rinses and boils until there is absolutely zero color left and the distilled water remains crystal clear. Then, do a second nitric acid treatment, and you will notice zero color change or fume production. Proceed again with several distilled water rinses and boils to rinse the gold well, and then you can proceed to aqua regia. Please try this method. Your subscribers need to see this. Thank you, sir. Copper Inquarter
Would love to see an experiment where you do a full process of aqua regia x3 and acid boils x 3 for 1 ounce bar, and then a second bar with aqua regia x2 and acid boils x 2, and then get the two bars tested for purity to see what the differences are..?? Keep up the great videos
Random request. For a video, could you leave out the expected yield from your equations so we can try guessing the final weight? lol. I try doing it from time to time based on the starting gold weight and how much enquarted gold/ gold sludge there is 😅😅😅
The result is what I watch it for. As a chemist, I’m always looking for sources of error that creep into the process… He isn’t exactly sure if his input, so any result will be a guess.
100% don't mess with chemistry unless you understand chemistry. You absolutely can die playing around with it. But if you understand you're a wizard Harry.
Great vid sad part is a lot of “ gold dealers” won’t buy unserialized self poured bars unless they have XRF on site to determine purity or drill it. Love the vids though.
Why do you do multiple refinings if you just sell the gold to a refiner which will refine it again? Is it financially advantageous, or maybe I'm mistake about what you do with the gold afterwards. Thank you for the great videos. Your excellent at explaining what you're doing and why.
it seems to me that adding the non reagent grade stump out adds impurities back in. Would it not be better to dissolve the stump, and filter it before adding it for precipitation? I would love to see it added slowly in ionic form to the gold and watch what happens with a stir bar.
I’ve done it before, but it’s been a long time. Someone suggested pouring the gold into a sat solution of stump out. I might try that for my next gold refining video.
While I like the clear video shots in the resent refining episodes, I still think having a secondary containment vessel would be prudent. Maybe a clear Pyrex vs the Corning Ware as a compromise. Your lab, your rules. Stay safe.
have you thought about getting other "molds" maybe one that has sreetips already indented? second stumpout first spoon was like a winter land but of gold.

Honestly Im waiting for you to come up with a genius way of capturing the NO2 gas coming off of the nitric boils. You have a unique way of doing things, so I have confidence it'll be a cool setup. Why capture NO2? Because bubbling it through distilled/deionized water makes more nitric? (To answer the question preemptively for the audience : )
While NO2 is the major component, it’s not the only nitrogen oxide. That’s a mix of N2O5, NO, N2O4, too. It could be ported into his Ag recovery pot for one more ‘use’.
Any chance in a future video you can do a cost/profit analysis of the refining in that video? For example, how much did the gold scrap cost you, the scrap silver used to inquart, the hydrochloric/ nitric/ sulfuric acids, and SMB?
He’s never done it, to my knowledge. Nor would I ask him. It’s his ‘business’ not yours. The cost of equipment you can figure out on your own. The cost of chemicals you can estimate on your own. You can calculate the value of the produced Au. No one but God and Mrs S could know what was paid for the material. There’s volumes of worthless scrap, diverted stones of unknown value and the kicker: labor. He tells us this is a hobby and not a business, and he doesn’t tell us how much time he spends sorting the materials to make his inquartation calculation. That’s on top of the 12 hours he clocked to win these >3 OzT of Au. I’d peg his labor rate at $200/hour… 14-15 hours? Then count Mrs S estate sale hunting time and costs. Sreetips works hard at this…
Think of it this way: you could use liquid dish soap with no water to wash your hands. It would get them clean. But if you add a little water it works much more efficiently. The water provides a place for the metals to dissolve into.
It does not matter how many times you watch, you always pick up something new from your commentary. Fantastic stuff and what a beautiful bar at the end :)
I like the addition of the clock because it keeps me from asking stupid questions like “how long does this or that take. I also like watching the stump out work. If you put 10 minutes worth of that in 1 video, I’d watch it for ASMR purposes ❤
After watching many of these I would love to see a time lapse of stump out working on an actual stump
I don't think setting it up would be possible, but a time lapse of the silver crystals growing in the silver cell would be awesome.
Gets better every video .. Youve come a long way in your refining processes.
This bar was absolutely beautiful!
Gooood evening from central Florida! Hope everyone has a great night!
Hey fellow central floridian!!!
Heyo from Colorado Springs!
Goooood evening!
A brand new Sreetips video!?! I needed this tonight. 60 hour week at work just ended. I’m beat.
As always, just completely in awe of your process. Refining two metals at once is genius. And I dig that neon clock!
Time-lapse is awesome with the clock in the background, thanks! (And that's a neat clock!)
I appreciate your nitric acid explanation. I also appreciate the variety of clocks in your videos.
I love the drop the patterns that it makes are memorizing and beautiful thank you for sharing another awesome video with us six stars sir
always a good watch, and you do a great job with your production quality on video as well - just the right amount of commentary - very educational.
Always a pleasure to watch your progress in action, and the results are FANTASTIC!!!
Do you think the 2nd filter step could also have been skipped using the ice and beaker for the next reaction? I do like seeing the gold after the hydrochloric boil as it goes from dark chocolate cake to milk chocolate sponge. The gold looked fabulous after the 2nd refining. Love your work as usual my friend..👍
I just love you, your a Wizard! I sit and watch your videos amazed every time. Thank you!
Never disappoints! Great vid. That SMB cloud NEVER gets old.
Beautiful! Love the added light on the precipitation.
Love what u do on this channel best channel at what u do. Fantastic work 👏 👍 👌 😊😊😊 amazing
Thanks for that
Damn, that bar looks perfect. Congratulations.
You are welcome. Always a treat to see your latest project produce another spectacular result, and getting there is more than half the fun. Thank you Sir!👍👍🤟
Thanks for the video Mr Sreetips. That 2nd precipitation was amazing to watch. Well filmed.
Glad you added the clock, it kind'a gives a perspective of how much time some of these reactions take.
That bar... so lovely!
Fascinating process, you clearly know your chemistry.
Love the neon clock that blue brings out the blue tint real good
The little white flame looking stuff on the bottom of the beaker when SMB is being added, is really neat to watch. Fascinating, absolutely fascinating.
Oh I love your videos! Learning so much 😸
29:35 a drop of dishwasher "rinse aid" here will help settle that much faster and help stay settled.
Even though I totally understand the chemistry involved, I'm still fascinated by the colour of the solution because I know there's a metal in there, but it's been *dissolved* and still has the colour I'd expect it to.
Wow beautiful how sharp you can see the precipitation of the gold 👍🏼🇬🇧😃
Hello sir, the quality of your videos and of your poured bars goes up and up constantly... Amazing...
What I look forward to most every day is watching SREETIP release new videos
I'd say that about 50% of the appeal to these videos is the rinsing...THE RINSING!, and the impeccable hygiene in general. Nice bar, by the way, I want to sink my teeth into it.
Nice work Sreetips, thanks again for sharing your work with us.
Thank you for adding the clock to your videos.
Amazing work my friend
That close up of the nitric fumes coming from the silver jar was so neat and another stunning gold bar at the end. 👍
Thank you again from Berea Kentucky
That's one of the best bars you've poured in some time Mr Tips. Impressive shine on this one sir.
the first smb precipitation when you first start to let it settle after stirring looks like some sort of pumpkin cider or something, kinda scary how apetizing some of this stuff can look considering the chemicals involved
The gold solution with ice looks nice for a hot summer day drink.
I always say the puddle of gold in the melt dish before the pour is a "forbidden egg yolk" cracks me up every time
I've been bed bound due to health issues and I love your videos. My only complaint is that you don't post more often, but I understand it's a hobby and I'm thankful for what we get!
I’m getting older myself. When producing these videos it takes a hundred and ten percent of me. And I’m wiped out for a day or two after posting.
@@sreetips I'm sure of it! I hope you took it as a compliment. The videos you produce are great!
I’ll get some new videos posted this week. Thanks for watching!
Adding that clock is brilliant🤯
The pour filled the mould perfectly, so satisfying and verve racking to watch. I thought you were about to have another overflow 😂
Thats the best looking gold bar ive seen in a long while
Try putting the light behind the beaker pointing towards the camera. That should give you real good illumination to see the reactions
Who said Chemistry was boring ? This stuff Never gets Old !
That's a fine chunk of gold, .999 fine.
That is one of the prettiest bars you’ve ever done
Not only was the refining perfect but you poured that Gold into the mold like a Boss! I hope i can find everything in your video on Amazon 😁
I like the addition of the clock
You truly do have the Midas touch.
My favorite part is the reaction of the SMB.👍
WHAT a POUR...!!!! Great job, you nailed that one!!
reliably great content
One of your best bars yet. Top ten, gotta be.
Awesome as always!
I believe the term you are searching for is "saturated" regarding used but active nitric acid being saturated with base metals
The fume hood is good for human safety but also because nitric fumes will rust literally every piece of steel in your workshop, sink, pipes, etc. That stuff is really high on the corrosive scale. Also please don’t dump it down the sink or toilet, into the yard, sewer etc… Be like streetips and treat your waste properly. 👍🏻
Thx sreetips another fine video 🇮🇪
Thank you so much for all your hard work,but I can’t help but when you add sulfuric to drop lead I wonder if you could get a surplus nitric bye trying to dissolve lead again .".
It's always amazing to watch you work.
And thank you Sir.
I can only agree :) It IS a spectacular bar and it's fun to wtch you make it
The bar came out really good, given that you even tried to save on effort at some stages. You seem to be really optimizing the process both in terms of labor reduction and the quality increase!
That's one good looking Gold Bar...
@sreetips why don't you show the stannous test after precipitation with SMB.. Just to see what's left in solution.. Any orange or green
Didn’t think to do it.
27:35 Sometimes it's the little things in life that make you happy

Add a little sand to your capture dish to even the heat to stop 🛑 cracking your glass 🍷

Very beautiful little bar. Thanks for sharing with us.
I am guessing that it was 999 fine? What more would you need to do it to make it 9999 fine?
Electrolytic gold refining will get four nines gold.
Why do you do multiple refinings if you just sell the gold to a refiner which will refine it again? Is it financially advantageous, or maybe I'm mistake about what you do with the gold afterwards. Thank you for the great videos. Your excellent at explaining what you're doing and why.
For the show
I have that same portable stove top. I use it for making wort for beer. Works great.
My favorite moment is when the gold powder becomes an ingot.
Yeah, watching you rinse the beaker that has the aqua regia in it is oddly satisfying
Spectacular looking bar ❤ ... what type of disposal gloves do you use?
Nitrile
great bar I like the clock it tells us how long it takes you thanks.
Very nice for looks awesome
Great looking gold!
Hey screetips i missed your videos already
Sreetips, can you give us a rough summary of the volume and costs for all the supplies you used to purify 82 grams of AU to 4 9s?
Less than fifty bucks all in (not counting the gold).
it seems to me that adding the non reagent grade stump out adds impurities back in. Would it not be better to dissolve the stump, and filter it before adding it for precipitation? I would love to see it added slowly in ionic form to the gold and watch what happens with a stir bar.
I’ve done it before, but it’s been a long time. Someone suggested pouring the gold into a sat solution of stump out. I might try that for my next gold refining video.
Sreetips entered a new speedrun category - refine 3ozT 999 gold from karat scrap - 12:00
This bar looks amazing, kudos, love watching your process
Can you do a video on your process of purchasing your materials? That includes gold and silver.
I’ve done a few
Another awesome gold bar thanks for sharing sreetips
While I like the clear video shots in the resent refining episodes, I still think having a secondary containment vessel would be prudent. Maybe a clear Pyrex vs the Corning Ware as a compromise. Your lab, your rules. Stay safe.
Agree
have you thought about getting other "molds" maybe one that has sreetips already indented?
second stumpout first spoon was like a winter land but of gold.
Could you use the cement silver powder for the inquartation instead of sterling?
Yes, but it’s not recommended because palladium will build up in the cement silver .
I like the new clock

Why dilute the nitric? Always wondered. Love your channel and I'm still waiting for you to auction off your precious metal shirt lololol
Think of it this way: you could use liquid dish soap with no water to wash your hands. It would get them clean. But if you add a little water it works much more efficiently. The water provides a place for the metals to dissolve into.
Water is in itself a polar solvent many compounds are water soluble.
Yes, having much water present to dilute the nitric acid aids the reaction.
