I know this won't make much sense out of context .. I want to thank you for being one of *THE* most honest people on TH-cam. Your successes, your failures, it doesn't seem to matter to you, and this is only a good thing... Whatever happens, you address things for how you see them. And you present that to us in raw form. I for one greatly appreciate the lack of *any* sugar coating. Thank you Sreetips, if that's your real name... [🤣] *ALL* of your work is greatly appreciated. Doesn't matter if we can use it directly or not... It is all useful. Please never stop being you, man. This is the kind of content the world needs. And I'm here to see all of it.
Yea. It just does not transform into something else. To transmute gold into lead you would need to put it into a nuclear reactor. Plenty of donuts will believe it is ruined and lost though.
Actually it does react with oxygen but only in specific conditions. This is what the H2O2 (here) or the nitric traditionally does, donates oxygen, briefly creating an oxide that the chlorine in the HCl then can attack. It's a "pretty" dance on paper.
This is why this channel is so good - unadulterated videos showing the highs and lows. From my point of view I cannot think of a form that gold would take that would render it completely impervious to re-dissolving in aqua regia. However I could be wrong and maybe a certain percentage will remain unreacted - we will have to stay tuned! :)
The obvious first step is to simply add distilled water to the chloroauric acid crystals. We already know that it readily dissolves in water. The only real concern is that some of the gold may have become airborne particles and went up the fume hood.
I just got to the end of the video and I'm super impressed. When you buy gold (III) chloride crystals they come as a bright lemony yellow solid. You can see some in there, especially around where the crystals were forming at the meniscus at the phase change from liquid to solid. The purple/brown solid looks to be the hydrogen tetrachloroaurate in the anhydrous form (I'm guessing as I've never had a couple of thousand bucks to burn away!). You really ripped most of the water molecules out of that one! Nice work. Yet another interesting, if unintended experiment in the name of science. I don't think Mrs Sreetips has much to worry about. Some more HCl and H2O2 or AR should sort that one out fairly easily although an extremely tiny amount will have sublimated into the air.
@@PaulBrown-uj5le True it will be tiny but gold chloride does have a tendency to sublime when heated. Can't tell you at what temperature that becomes an issue because I can't remember - I did inorganic three decades ago - but I'm sure it will be online somewhere.
Great video Sreetips! I asked you sometime back if you could do a demonstration of what would happen if you had lead in the solution. Thanks for the demonstration!
We should have an Annual Sreetips channel meet up / hang out. Open bar between 5pm and midnight ! We can meet in Vegas and we could bring precious metals to melt and play with lol
Now that's a cliffhanger, and I honestly never thought I'd see one on your channel, well done! I love that you do this just to educate us, and it's greatly appreciated. I know it's still recoverable, but seeing mistakes, and how to avoid/correct them is fantastic, thank you.
Loving the cliffhanger element to your pattern of storytelling. Thank you for lubricating the process with some lead...which led us to this place of opportunity to discover what happens together in a fun and exciting way. Looking forward to the next steps here. Thank you so much for these insights.
Another amazing Streetips video. Sucks that this happened, even a highly skilled pro like yourself can have slip ups sometimes. Just shows you're human. Hopefully there is a way to resolve this issue with no loss. Also, you're welcome for suggesting to add lead to see sulfuric acid in action, I knew it would be a cool experiment, even though I got flamed by a few commenters for suggesting it.
I'm pretty sure, from what I've read, that you can reduce that dried Chloroauric Acid to metal again with just heat. Same as if you can precipitated with SMB. Don't even need borax. But I have read a lot and could be crossing this up with another thing! You certainly can't kill it, even if you had melted it into the Pyrex glassware. Before the discovery of things like SMB this was a way it was done. Also, you can purify with crystallisation as well as filtration can. So if you had stopped earlier and left it to cool and collected the crystals, and did this a few times, you'd get very high purity gold. Usually you find that the crystals collected at the start look different to the ones collected at the end, signifying that there is another metal or compound present.
I can't see why you couldn''t recover your gold out of that dark residue with a straightforward aqua regia treatment. You might have to cook it for a while. I shall follow with interest!
Very informative video. I love it when you introduce things like this into the experiment for your benefit and ours. Been watching your videos for years and am glad you finally did this. Go Sreetips!!
I think that adding distilled water first to rehydrate the crystals, if they can be called such, and then add fresh aqua-regia and then of course heat and I think it will go right back into what it was before bring brought down to this dry form. If this works out this may be a way to store gold in a form that would not be recognized by the average lay person, and you could label it Refining waste and no one would be the wiser. LOL
I'm looking forward to part 2 of this one. Will you rehydrate it, will you redissolve it, or will you do something completely different with it? It'll be fascinating to see. 👍
Ever since I began watching your videos, I wondered about the lead thing. Now I know. Very informative and interesting. Since you ad sulphuric acid in each refining step, do you encounter a lot of lead when you process your paper filters en masses? I would think hundreds of them would contain an accumulation of lead.
so the stannous chrystals make your solution look white?! i always wondered why it looks so different than mine. mine old stannous turned yellow, is that normal? it still woked tho but i think it went bad
Heating the Auric solution until it dries is actually a good method after using Aqua Regia to evaporate any leftover nitrates, which could redissolve precipitated gold back into the solution. It that case however, it is enough just to dry it out, not burn it down.
I’m sure you will work your magic! Have you thought about getting a chest harness for your go pro? It’ll make it so you won’t have to work around your tripod and stop it from getting it in your way. Just a thought!
Sir just add distilled water and hydrochloric acid I would think that would bring it back? This has been very informative and interesting thank you for sharing this with us six stars
I did the same thing yesterday. In fact I've done it many times. You have highly acidic crystals, they just need hydrating. Some gold will already be in metallic form, beautiful gold. Super Super fine, like tiny specks of glitter. Not a problem just drop it out.
I would assume its just a case of rehydrating and dissolving the gold again? Early in the video you mentioned using hot tap water, would this not create issues with all the impurities in tap water? Great video though showing when things dont go as planned.
the lead shot you used, was it from ballistic lead? ( lead for bullets or shot gun shells ) if so it could be a tin or antimony precipitate of some sort.
15:49 solution in the funnel looks unironically like sunny delight, haven't had that stuff in years, i don't even know if i even see it in stores anymore
Well I am guessing that since you have a mix of yellow and brown in the beaker, some of the gold has become the anhydrous (brown) and some is still in its monohydrate form (yellow). Now it is possible that the excessive heating may have converted the Gold (III) chloride into Gold (I) chloride driving off Chlorine gas in the process. If that did happen then when you go to rehydrate the powder it is possible that not all of it may dissolve. 😅
Yeah, possibly, it could be a mix of both like you say or there could be something else going on we don't know about, but that's the next episode of Sreetips crazy gold show😂😂😂
This is a great answer! The anhydrous form should be red-brown and agree with the (III) to (i) oxidation state. Bright, lemon yellow to a darker orange-yellow. More heat would result in dismutation --> elemental Au + more in (III).
Thanks streettips.. The alchemy stuff I've read is the red is very very powerful .. Like 1/4 what you grab in twesers In a quart of everclere. Than put a drop of that in your fav beverage 2 times a year
Great video how to make stannus chloride. Seeing gold, platinum, and palladium colors on stannus chloride strips. Awesome. Getting lead out a gold solution. Awesome. Then burning the gold. Lol great video
Absolutely top draw brother and left the episode on a knifes edge. Streets do you have a video on the chemicals needed and where to purchase them from.
I believe the precipitate that was in your solution was lead nitrate or lead 2, lead chloride is soluble and nitric acid but lead acetate is not, so it may also be lead acetate
hello mr. sreetips. one simple question. what type of y paper do you use? I almost finished my pack, but it doesn't say what type it is. As in "slow, medium, fast". Thanks!
Oh man.. what a cliffhanger. I've always wondered what would happen if you cooked the gold for too long... I always figured you would just have to rehydrate the burnt crust but now seeing it in person I don't know if it's going to be that easy.
I have a strong suspicion that will readily go right back into solution. If water alone doesn't get most of it, a little extra help from a bit of HCl/H2O2 would get things right back where they started
I think it will desolate pretty good in aqua regia. Maybe a small amount lost but it can be recaptured in his filter collection. I don’t think he has actually lost any gold.
yes that is lead chloride Pb(NO3)2 + 2 HCl → PbCl2(s) + 2 HNO3 is the formula according to Wikipedia also there might be a reaction with lead oxide directly with the hydrochloride PbO2 + 4 HCl → PbCl2(s) + Cl2 + 2 H2O i think this is the one following the gold until you add the sulfuric acid.
It's fine. You're partly right about chloroauric crystals, assuming any survived. The rest of it thermally decomposed into gold and lead oxide, possibly an alloy if the lead didn't oxidize. Hard to say how much of each since both substances are yellow to brown in color. If you deal with lead in the future, might be worth looking into bone ash cupels.
4:12 I honestly expected that you would need to let the stanis solution sit and dissolve the tin and stir it up, but no, that's pretty interesting. What colour does osmium come out as (if you know).
What's happening stranger I have a question. Refining gold pins, I dissolved with aqua regia. And precipitated with smb. Since I'm out of nitric acid and hydrochloric, but I have 93% sulfuric acid. For my second refining can I just use sulfuric acid alone to refine the powder? Would it not dissolve everything but gold?
This would have been a great time try a bit of drug store iodine on one of your filter papers to test for lead. Hopefully you can rehydrate and recover from the mess at the end.
Lead shot could have tin and antimony . They use them to make it harder. 92% lead 6% tin and 2% antimony is a common formula used to make it harder. like anything in this world there are many different formulas to making lead harder. that is mostly for casting bullets and i have seen silver in those alloys.
I would dissolve it in HCL, you may need to add a little nitric , then PPT out with stump out. Or you could send it to Jason at mbmms and he would smelt it out with some borax and a collector metal :)
16:52 I would put money on it that you have removed all the lead that you added. If you were to weigh the powder left from the lead sulphate and chloride it should weigh a bit more than the lead you added. I'm surprised at how fine the lead sulphate is. On that note, what process gives you the finest particle size of gold?
Conditions vary. I’ve seen it do fine that the amount of gold powder seems like you got ripped off. But then it’s all there (expected yield) when I go the melt. I don’t know what causes that to happen.
I sent you an email a couple of years ago about a stockpot that was given too me. I finally decided to tackle the problem. Im running into some weird issues. Im considering trying electrolysis for the copper, silver and gold. But, I don't know what this sludge is made of 😂. So far I have taken 5 200g samples but there's something interacting with the solution that's making nothing come out of solution. I use stanus to test for gold and hydrochloric acid to test for silver. The only thig i have been able to find out about the original solution is that the person used "a lot of SMB to neutralize everything." I don't even know what that means 😂. If anyone has suggestions let me know. This is a bit of a personal vendetta at this point.
Haven't gotten through the vid yet but did you test the lead shot to see what amount of silver was in the lead shot you got? You should just cupel the lead out to see you have an electric furnace like the guy from mbmm
I’ve never used cupel. None of the professional refiners that I learned from used cupel. So I never learned to use it. Plus, a refiner really doesn’t use cupel. That’s more of a mining/assay process.
Hello Mrs and Mr sreetips. I am so happy to join the best chanal om youtube again. I have going to cronical pain in my body,but finally i get good help from my doctor 🙂 What a shame you gold loss. I have not see the full clip but i read the first words. Have i nice day both of you Sit. Arne
@@sreetips Sir...and so many new people in the sreetips family. Say hello to you family my friend. God bless the family and you Sir. You doing yust fine 💌
No, Ice does not kill excess nitric. Nor does urea. The best way to kill excess nitric is to evaporate down to a syrup, then rehydrate with HCl. I add ice to precipitate out and silver chloride so it can be filtered out.
Lead, in just trace amounts, ruins the malleability and ductility of gold. So I add sulfuric acid to each batch to reaction any lead that may be present, whether I suspect lead or not. In this experiment I added lead to see if I could detect the lead that added.
Well, at least we know there’s no excess nitric in it 🤔 Maybe rehydrate with distilled water…. That’s what would be done if you purchased those crystals for lab use. If all else fails you can explore using piranha solution 😄
Hey Professor S., I've been wondering whether you buy your distilled water, or rend it yourself. Reason is, I bought a countertop unit recently, which makes 1 gallon in 5 hours, for my own drinking water, and it's really slick. Distilled water is about $4.50 per gal. where I live, so this was a great investment for me. I've seen you using commercial dw in your vids, but maybe you're just using the same jugs like I do now. If you run one of these machines for labwork, they sell a tester that will show if you're doing it right, which would verify it's purity for qc. The one I bought is an H20 Labs stainless unit, made in USA It's something that I'm pretty happy about, and wanted to ask you.
I use grocery store distilled water. It’s been $0.99 per gallon for ten years. Then about a year ago they raised it to $1.19 then recently it went to $1.39 but I don’t blame them. They have to do this to stay in business. The water hasn’t become more valuable. Nor more scarce. The value of the currency (US dollar) has lost that much purchasing power. That’s not the grocery stores fault. That’s the fault of the central bank, printing money out of thin air to avoid financial disaster. And that’s why I don’t store my savings in paper dollars. I store my savings in GOLD. That way a forty percent increase in price (due to money printing) doesn’t bother me a bit. High interest rates, and failing currency are not my concerns. We planned for this decades ago when we converted out paper to metals.
@@sreetips Amen brother, you're way ahead of the sheep with all that. Inflation is killing us here in Alaska, it's really a drag. At less than a buck fifty a gallon for dw, I'd just buy it too. Good enough, thanks for your response and great channel....Carry on !!
The line between the haves, and the have-nots, is drifting upwards rapidly. Some items have increased a hundred percent. All the numbers being given are cooked. Just wait until people begin to realized that their valuations are based on a mountain of debt. It’s not what I want to see. But it’s what we’ve allowed them to give us. The only way I see to protect yourself (financially) is with real money: GOLD and Silver.
@@sreetips Totally with you, these Keynesian economists are wiping out our birthright as Americans, and they should be nowhere near seats of power. I think you've done exactly the right thing, for your retirement years, and your economic philosophy is spot on.
Well I'll give you your credit my guy it's the first time I seen u mess up lolo and I ain't mess up really I know u know what to do next .. u may lost a lil bit but u good lolo no more Lead lolo
39:36 you did most of the hard work so from here it’s easy even NaOH and sugar will get your gold back from the hydrated solution, or you can switch the sugar for oxalic acid… or you can use sodium nitrite solution to hydrate and precipitate the gold at the same time… options are countless
I took the easy, familiar route; rehydrate with HCl and hydrogen peroxide, filter, precipitate with SMB. The ingot still came out trashy looking. Might have been the dirty melt dish.
Random question. If i bought a bunch of gold, dissolved it into solution so it just looked like yellow water, kept it in a 5 gallon Poland spring jug, overtime would it fall out of solution? Asking in an apocalyptic scenario where a gold bar is much more easy to identify an steal than yellow liquid
Dissolved gold won't come out of solution without some external cause. There is that true story about the Nobel gold medals that were dissolved to keep them safe from the Nazis.
Gold wouldn't come out of solution, but your Poland Spring jug would disintegrate in short order. Assuming it's kept sealed in a vessel that it can't attack, metal solutions in aqua regia are stable indefinitely.
Why don't you pour the extra silver nitrate solution through your partially filled anode basket, mr Sreetips? That way you can replenish the amount in the bowl below AND you enhance the conduction through the silver shot somewhat, in my opinion

Fortunately gold doesnt react with oxygen, and we all know you're just going to re-agua-regia it and re-precipitate it and itll be just fine.
Yea. It just does not transform into something else. To transmute gold into lead you would need to put it into a nuclear reactor. Plenty of donuts will believe it is ruined and lost though.
At least 5 times haha
Luckily, alchemy is not a thing, short of fusion and fission reactors. Sreetips cannot transmute base elements to gold or vice versa.
Hydrochloric acid will suffice, no need for nitric.
Actually it does react with oxygen but only in specific conditions. This is what the H2O2 (here) or the nitric traditionally does, donates oxygen, briefly creating an oxide that the chlorine in the HCl then can attack.

It’s not going to be airborne. It might spatter out if he bumped (over boiled) the solution.
Correction: add HCL.
why would they become airborne, is not a volatile substance?

I have a strong suspicion that will readily go right back into solution. If water alone doesn't get most of it, a little extra help from a bit of HCl/H2O2 would get things right back where they started
I think it will desolate pretty good in aqua regia. Maybe a small amount lost but it can be recaptured in his filter collection. I don’t think he has actually lost any gold.
@@emeraldkind Nope. He's good. Just a scare.
yes that is lead chloride Pb(NO3)2 + 2 HCl → PbCl2(s) + 2 HNO3 is the formula according to Wikipedia also there might be a reaction with lead oxide directly with the hydrochloride PbO2 + 4 HCl → PbCl2(s) + Cl2 + 2 H2O i think this is the one following the gold until you add the sulfuric acid.
Sorry that happened but it's very interesting to watch. Thanks for another informative and great video.
Could you be able to make a different stanis test solutions to test for lead. It would be kinda cool to see what color it is on a test strip.
Stannous test solution only works for precious metals.
It's fine. You're partly right about chloroauric crystals, assuming any survived. The rest of it thermally decomposed into gold and lead oxide, possibly an alloy if the lead didn't oxidize. Hard to say how much of each since both substances are yellow to brown in color. If you deal with lead in the future, might be worth looking into bone ash cupels.
What lead?, he got rid of it long before it was dry burned...
@@PaulBrown-uj5le Jumped ahead in the video. Regardless, the gold is still there.
Thank you for going out of your way to show us how to produce noble metels
Seems like rehydrating with hcl boil would fix the issue.
I'm pretty sure all you need to do to rescue it is just redissolve it in aqua regia and it'll be fine.
4:12 I honestly expected that you would need to let the stanis solution sit and dissolve the tin and stir it up, but no, that's pretty interesting. What colour does osmium come out as (if you know).
I don’t know
What's happening stranger I have a question. Refining gold pins, I dissolved with aqua regia. And precipitated with smb. Since I'm out of nitric acid and hydrochloric, but I have 93% sulfuric acid. For my second refining can I just use sulfuric acid alone to refine the powder? Would it not dissolve everything but gold?
This is Jay Charter from back in the day here on TH-cam
Sorry, I don’t know.
Howdy!
I have a feeling there is a bit of a dramatic flare here, but I am pretty sure distilled water and a low heat would rehydrate just fine?
Good luck!
This would have been a great time try a bit of drug store iodine on one of your filter papers to test for lead. Hopefully you can rehydrate and recover from the mess at the end.
How does iodine indicate lead? Sounds neat.
Lead shot could have tin and antimony . They use them to make it harder. 92% lead 6% tin and 2% antimony is a common formula used to make it harder. like anything in this world there are many different formulas to making lead harder. that is mostly for casting bullets and i have seen silver in those alloys.
I think all you really need to do is rehydrate with HCl and maybe very low heat to help redissolve.
Nothing to worry about. Just rehydrate.
Do you think putting the setting gold beaker in the ultrasonic cleaner will help with settling speed?
I don’t know. Boiling it causes it to settle quickly.
I have a may be stupid question.
What would happen if you just leave the pure gold solution to dry out? Will the gold crystallize eventually?
Never mind I guess, I got an answer from the video just a couple minutes later I asked it))
What’s the solid stuff that accumulates at the bottom of the gold refining waste flask?
GOLD!
U could drip your test solutions on the filter from funnel to see what was white precipitation since your tossing it
I would dissolve it in HCL, you may need to add a little nitric , then PPT out with stump out. Or you could send it to Jason at mbmms and he would smelt it out with some borax and a collector metal :)
when smelting, lead is used as a collector metal. i wonder if lead can be used similarly in the chemical refining.
Smelting (recovering metals from ore) and refining are two totally different processes.
just looking for overlaps. like using borax to clean away the surface of a molten metal, and the like@@sreetips
16:52 I would put money on it that you have removed all the lead that you added. If you were to weigh the powder left from the lead sulphate and chloride it should weigh a bit more than the lead you added. I'm surprised at how fine the lead sulphate is. On that note, what process gives you the finest particle size of gold?
Conditions vary. I’ve seen it do fine that the amount of gold powder seems like you got ripped off. But then it’s all there (expected yield) when I go the melt. I don’t know what causes that to happen.
I sent you an email a couple of years ago about a stockpot that was given too me. I finally decided to tackle the problem. Im running into some weird issues. Im considering trying electrolysis for the copper, silver and gold. But, I don't know what this sludge is made of 😂.
So far I have taken 5 200g samples but there's something interacting with the solution that's making nothing come out of solution. I use stanus to test for gold and hydrochloric acid to test for silver. The only thig i have been able to find out about the original solution is that the person used "a lot of SMB to neutralize everything." I don't even know what that means 😂. If anyone has suggestions let me know. This is a bit of a personal vendetta at this point.
Stock pot is a concoction of everything. Who knows what lurks in there. I’ve refined four or five. And it’s different every time.
Haven't gotten through the vid yet but did you test the lead shot to see what amount of silver was in the lead shot you got? You should just cupel the lead out to see you have an electric furnace like the guy from mbmm
That was industrial lead, no silver in there as that is much too valuable (compared with the lead).
@@apveening makes sense I just had to ask 😁
I’ve never used cupel. None of the professional refiners that I learned from used cupel. So I never learned to use it. Plus, a refiner really doesn’t use cupel. That’s more of a mining/assay process.
Nano gold particals are red hence the red colour in stained glass
Hello Mrs and Mr sreetips.
I am so happy to join the best chanal om youtube again. I have going to cronical pain in my body,but finally i get good help from my doctor 🙂
What a shame you gold loss. I have not see the full clip but i read the first words.
Have i nice day both of you Sit. Arne
Good to have you back.
@@sreetips Sir...and so many new people in the sreetips family. Say hello to you family my friend. God bless the family and you Sir. You doing yust fine 💌
And thanks for having me. I have really miss this canal. But the good thing is a lot of clip i can see 🙂 Arne
Sreetips with the Cliffhanger!! Well played sir….
شكرا يااستاذي العزيز على المجهود واريد معرفت شيء هل وضع الثلج فى البيكر على المحلول لقتل النيتريك بديل اليوريا وتحيد النيتريك ارجوا الرد على السؤال💖
No, Ice does not kill excess nitric. Nor does urea. The best way to kill excess nitric is to evaporate down to a syrup, then rehydrate with HCl. I add ice to precipitate out and silver chloride so it can be filtered out.
@@sreetipsشكرا لك استاذى العزيز على الرد و الإجابة تحياتي لك 👍💖
I just did the same thing! Add Water+Nitric +Sulfuric then bring to a boil! It will all come right off and you will be back in action!

Sreetips gittin burnt T.V. dinner tonight 😂😂😂😂
1 minute and I'm 9. People waitin on you Doc.
I must have missed it, even on my second watch, but why did you add lead to the gold in the first place?? Just an experiment of some sort?
Lead, in just trace amounts, ruins the malleability and ductility of gold. So I add sulfuric acid to each batch to reaction any lead that may be present, whether I suspect lead or not. In this experiment I added lead to see if I could detect the lead that added.
@@sreetips gotcha. 👍👍
Excellent learning video thank you 😊
Well, at least we know there’s no excess nitric in it 🤔 Maybe rehydrate with distilled water…. That’s what would be done if you purchased those crystals for lab use. If all else fails you can explore using piranha solution 😄
Or....just add hydrochloric acid.
Re dissolve it in aqua regia and repeat the process, is possible to solve also in HCl 37%
Should be
Wouldn't the silver push the gold out of solution seeing how silver is more reactive than gold?
What silver where?
@@apveening when he put the used nitric acid that had a trace of gold in solution. The silver that will go in solution will push out the gold.
I don’t think so.
Just redissolve it in HCl, Sreetips. It should be fine, not like it can "burn" as it's inorganic material.
Hey Professor S., I've been wondering whether you buy your distilled water, or rend it yourself.
Reason is, I bought a countertop unit recently, which makes 1 gallon in 5 hours, for my own drinking water, and it's really slick.
Distilled water is about $4.50 per gal. where I live, so this was a great investment for me.
I've seen you using commercial dw in your vids, but maybe you're just using the same jugs like I do now.
If you run one of these machines for labwork, they sell a tester that will show if you're doing it right, which would verify it's purity for qc.
The one I bought is an H20 Labs stainless unit, made in USA
It's something that I'm pretty happy about, and wanted to ask you.
I use grocery store distilled water. It’s been $0.99 per gallon for ten years. Then about a year ago they raised it to $1.19 then recently it went to $1.39 but I don’t blame them. They have to do this to stay in business. The water hasn’t become more valuable. Nor more scarce. The value of the currency (US dollar) has lost that much purchasing power. That’s not the grocery stores fault. That’s the fault of the central bank, printing money out of thin air to avoid financial disaster. And that’s why I don’t store my savings in paper dollars. I store my savings in GOLD. That way a forty percent increase in price (due to money printing) doesn’t bother me a bit. High interest rates, and failing currency are not my concerns. We planned for this decades ago when we converted out paper to metals.
@@sreetips Amen brother, you're way ahead of the sheep with all that.
Inflation is killing us here in Alaska, it's really a drag.
At less than a buck fifty a gallon for dw, I'd just buy it too.
Good enough, thanks for your response and great channel....Carry on !!
The line between the haves, and the have-nots, is drifting upwards rapidly. Some items have increased a hundred percent. All the numbers being given are cooked. Just wait until people begin to realized that their valuations are based on a mountain of debt. It’s not what I want to see. But it’s what we’ve allowed them to give us. The only way I see to protect yourself (financially) is with real money: GOLD and Silver.
@@sreetips Totally with you, these Keynesian economists are wiping out our birthright as Americans, and they should be nowhere near seats of power.
I think you've done exactly the right thing, for your retirement years, and your economic philosophy is spot on.
Well I'll give you your credit my guy it's the first time I seen u mess up lolo and I ain't mess up really I know u know what to do next .. u may lost a lil bit but u good lolo no more Lead lolo
39:36 you did most of the hard work so from here it’s easy even NaOH and sugar will get your gold back from the hydrated solution, or you can switch the sugar for oxalic acid… or you can use sodium nitrite solution to hydrate and precipitate the gold at the same time… options are countless
I took the easy, familiar route; rehydrate with HCl and hydrogen peroxide, filter, precipitate with SMB. The ingot still came out trashy looking. Might have been the dirty melt dish.
@@sreetips knowing your work, I’m sure all gold was accounted for… Mrs Sreetips can have her mind at rest :)
I re-refined the gold in my latest video. Came out looking very nice!
Random question. If i bought a bunch of gold, dissolved it into solution so it just looked like yellow water, kept it in a 5 gallon Poland spring jug, overtime would it fall out of solution? Asking in an apocalyptic scenario where a gold bar is much more easy to identify an steal than yellow liquid
Dissolved gold won't come out of solution without some external cause. There is that true story about the Nobel gold medals that were dissolved to keep them safe from the Nazis.
Gold wouldn't come out of solution, but your Poland Spring jug would disintegrate in short order.
Assuming it's kept sealed in a vessel that it can't attack, metal solutions in aqua regia are stable indefinitely.
First off what's a Poland spring jug😂😂😂
I think it will keep indefinitely.
Why don't you pour the extra silver nitrate solution through your partially filled anode basket, mr Sreetips? That way you can replenish the amount in the bowl below AND you enhance the conduction through the silver shot somewhat, in my opinion
Because I fear that some of the very fine particulate may get washed through the filter into the silver cell.
