Man, chemistry is the secret of this realm. These videos are filled with the knowledge that ancient alchemists used to keep guarded in secrecy .. there’s still secrets yet to be uncovered or rediscovered and the reactions and different types of methods of movement from one substance to another is so interesting to me .. precipitation and things coming in and out of solutions are some of my favorite reactions.. There’s not enough words to describe how magical Chemistry is .. I wish I had the means to go to school for it .. edit: untill then youtube shall suffice 😁
I lost count of the number of days it took to make these "buttons ", as well as the editing and narration. It must be a ton of time. Thank you for your passion in this project. Very grateful!
From Sunday through Sunday - eight days total - I cranked out six stock pot videos. It was like doing battle with those metals. But i loved every minute of it - except having to don that mic boom. I hate that thing. But the fume hood is so loud now that I can't produce without it. And it has to be pointed at my mouth just right. The wire pulls it out of place constantly. I need to get it fixed - probably an easy fix, I just haven't taken the time to figure it out!
I am an Italian goldsmith and I am a fan of your channel, I have seen that you have melted the PGMs and you have obtained a crust of impurities, if I can allow myself I wanted to give you a tip to get a clean metal perfect to be purified: Melt and heat to high temperature the metal in question, at this point close the gas tap and give a jet of pure oxygen to the metal, all the impurities will burn including some of the base metals, repeat the process several times and when the metal seems clean enough you can re-melt by adding copper or silver to purify it.
That was an out standing reaction. You we not kidding how beautiful it was to see. Thanks for all that you share with us both good and bad. That takes real courage to put yourself out there for everyone to see. simple is far from easy , and you make it look very simple with your no nonsense approach and execution. It was a pleasure to watch the whole series from start to finish.
So Sreetips showed me what that palladium salt was in my beaker, I didn’t know what it was until now so thanks for helping and showing. I should send you my stockpot it’s loaded with palladium but I am not experienced enough to do the recovery ☹️ Thanks for the series you are a very good refiner 👏👏
I appreciate you showing how you clean your glassware. I asked how it was done a little while ago. I'm always very curious about everything. Been this way my entire life. I love to understand the world around me. Thank you Sreetips!
That was a very beautiful reaction. Silver is still my favorite metal. But Palladium is up there because of the other colors it makes in its different forms. Alongside titanium and bismuth.
That was a beautiful blue it turned with the ammonia from the redish orange... and then back to that yellow gold color what an awesome reaction thank u for sharing the knowledge
Hmm, that precipitate looks like a goo I've been saving after test-dissolving a bunch of 'silver' plated pins from electronics. I should redissolve it in nitric and see if it's palladium.
Man that was awesome to see. I am always amazed with all the different reactions you do. I always wonder how someone first came up with these different methods to chemically refine different metals. Amazing stuff👍
That's definitely one beautiful reaction... The one before it while adding ammonia... That's one confused spectral thing going on there. Every color in the rainbow I think, back and forth... To settle on clear sky blue haha
You are correct with your idea that the smoke is ammonium chloride. It is forming above the liquid where the vapours meet. It is one of the nicer party tricks, having containers with both of the chemicals in a concentrated form and make sure the vapours encounter each other (in 1:1 amounts) before a fan.
Bravo 👏 👏 👏 bravo! Good job man! I was glued to the screen the whole time.. those r the craziest reactions and made me want to learn how to do that! U r the best at this I think. Uve been stepping outside ur comfort zone and growing because of it! Thanks for sharing
I think I saw you process your stock pot last time. I recall it being pretty cool, but this time was much better. Just seemed like the reactions were clearer and more spectacular this time. You're probably getting better at the camera and video production work too. It shows. Good job, Chief! And thanks for sharing 👍 😊
Really enjoyed this series. I never knew about cementing out onto iron, copper, an that whole swap with zinc helped me understand what is going on more. Overall though I just really love the silver crystals
I'm always amazed how much trust is placed in the fume hood; I don't think I could trust it, even if I knew the airflow was only and always going to up and out.
Awesome refining!!! One small correction at the end: the density is not necessarily proportional to the atomic number (even though the correlation is pretty good for metals). One good example is that Lead (number 82) is only about half as dense as Platinum (number 78). Your numbers are right for Palladium though, its only half as dense as platinum too!
Sreetips, thank you kindly for this wonderful series. Stellar work and I really enjoy watching your endeavors. Looking forward to what's coming, sir. Be well!
Now if you had a work-study arrangement with the local high school you could have some young kid doing the cleaning for you. Just like when you were a senior chief.
Congratulations on another very successful stock pot journey.. you're becoming very proficient at it. You were right, it was a beautiful reaction, thank you for sharing!
Hello Mr sreetips. Many maby not think, all the job after a video clip. You have to watc the sound.. The camera.. Clipping.. and the cleaning of beaker and flask. Thanks fore shoving that. Thanks fore this clip Sir,and have a Nice day😊
Sweet video. Cutting the handle: Modify as necessary. Field adjustment. I haven't seen that color blue because I haven't made it this far into that refining processes. I've been waiting for the anode basket refining process. I'd like to be able to process the anode basket filters, the paper filters & paper towels and the liquids separately to the point I can combine them together. Then drop the elements out one by one. It will be many months before I'm to that point though. Hopefully sometime soon someone will let you Sreetips behind the curtain to see the Rhodium recipe...L0L. Best wishes and have a wonderful Thanksgiving
Joe, I'm considering doing the anode filters - boil them in nitric until no more fumes evolve. Then just pour them all through my big buchner funnel. The filtrate should just be silver and palladium. The boiled filters will contain gold and platinum. Throw those boiled filter in with the paper filters and burn them all together all at once.
This was an absolutely fabulous series on recovering precious metals from the black sludge stockpot. It was a quite a journey, and we've made it to the end of the processes with flying colors. Your knowledge of chemistry is impressive, I took a basic chemistry class in college, so I have just enough knowledge to to be dangerous ;>) I'd like to do this, eventually, once I talk Mrs. Wade Hampton into it. She is rightfully concerned about the fumes (and so am I). Where do you vent your fume booth, and what happens to them once they are vented? I'd hate to injure a neighbor or a family member. I live in a regular neighborhood on a third acre lot, and I have neighbors on both side. There is a commercial property behind the back block 6' fence, and it's the delivery side of the commercial property with not much activity. It's something that I'll be needing to sort out if I decide to go this type business.
My chemistry experiments are infrequent and the amount of fumes minimal. Your neighbors car probably does more harm. The fume exhaust outside my work area.
@@sreetips thanks for clearing this up for me, sreetips, I'll take this under advisement. I've been interested in gold for for many years, and I own a small amount of precious metals. I'm an amateur watchmaker, and I gold and nickle plate watch cases and bracelets when needed, during the watch restoration process. I've never considered refining my own gold until I recently subscribed to your channel, and watched some of your videos. I'm fascinated by the processes that you are showing us, and I'm sure that I could do it myself. I'm a retired engineer, and I have the time and resources to set up a lab. I need to get the book that you talk about, could you please remind me what the name of the metallurgy book that you have on refining precious metals? I'd appreciate it brother! God bless you and your family good Sir.
Yeah wauw. Another great serie of stockpot refining video's. Looks indeed there was a bit of an issue with the rinsing and gues you have something to dig into. Personally I wouldn't have sold these buttons but hey, it's your stuff. Thanks for making these videos.
It's a good day whenever I see the next installment of a Sreetips video. Saving up for the next time I can buy some quality Sreetips-refined precious metals on eBay. :)
To clarify a comment I made a few days ago.. I thought Sreetips had a Tupperware container full of filter papers with small amounts of palladium salt he's been saving and I was wondering if those were going to go into to this refining.
32:52 - _"Palladium has a number [= an atomic number] of 46, Platinum is 78, so Pt is nearly twice as heavy - that makes sense"._ - Well, yes, "in a sense"... While atomic number and *atomic* mass are rather closely related, the density of an element AND its atomic number aren't so. The best case in point is gold vs mercury - atomic number [a.n.] for Au is 79, for Hg it is 80 - yet the density of gold is 19.3 g/cm3 while for mercury it is "only" 13.5 g/cm3 (meaning, gold is almost one and a half time as dense as mercury despite heaving lower atomic number). And it continues elsewhere - Uranium has a.n. = 92, significantly higher than a.n. of Au - but its density is slightly lower than that of Au (19.1 g/cm3). Osmium (Os), however, having a.n. lower than that of both Au and Hg, that is 76, is the densest stable element out there - one cubic centimetre of it weights 22.6 g. For comparison - Pt's a.n. is tad higher, 78 - but its density is lower, 21.4 g/cm3. Iridium (Ir) has a lower a.t. than Pt, namely 77 - yet its density is 22.6 g/cm3. And then there's thallium (Tl) with a.t. = 81(higher than that of all above elements, except for U), yet it's density is a paltry 11.8 g/cm3 - the lowest of them all above... Therefore, caveat emptor! QED ;-)
@@sreetips Precisely, as Pd has lower density than Pt, and I'm not arguing that. All I wanted to point out was a "discrepancy" between atomic number/ mass (which are rather closely related) and DENSITY of a given element (or compound) as there's no clear and "fixed" relation between those two. Lithium has atomic number = 3, atomic mass ≈ 7, and it's density is around 0.53 g/cm3, while radon (Rn) a.n. = 89, a.m.= 222, and it's density is below 0.01 g/cm3. LiH, lithium hydride has m.m = 8, density 0.78 g/cm3; SF6 (sulphur hexafluoride) has m.m. = 146, density = 0.006 g/cm3. And so on, and so forth - so it's better to avoid linking atomic number or mass with density, as it might be misleading (and quite often it is). That's it, that's all. Also, Pd and Pt are in same group in periodic table so this relation between a.n./ a.m. is sorta-kinda expected, but it is not that "linear" after all - Ni (above Pd) has a.n. 28, a.m. nearly 59 (means, "nearly half" of that of Pd),, but it's density is only slightly lower (≈ 9 g/cm3 vs 12 g/cm3 for Pd, which is ≈ 75% of Pd).
@@sreetips In fewer words: The Pd atoms in crystalline form are farther apart than those of Pt in crystalline form. Thus one cubic cm of Pd has less mass (atoms present) than the same sized cube of Pt. Don't get him started on the difference between weight and mass.
So all that platinum and palladium came from gold refining traces? I recall you mentioning that your silver cell slimes would contain pd and pt, as they are more "related" to silver than gold. I don't recall seeing your silver stock pot, but presumably there would be more pd and pt in your silver processes than your gold ones?
I'm not sure who NileRed goes through, but he gets his labware personalized. Might contact him and ask. Save you from having to marker it all the time.
Hi Sreetips, definitely went better than the previous 2 stockpot cleanups, what did you do with the waste solution from Pd. I assume you wouldn’t want it in the stockpot, so would it go straight to the waste solution with iron? Or how is it treated? Thanks for sharing, great recovery.
Have you considered buying a lecture bottle of chlorine gas for this precipitation, or others that can use chlorine gas? It is much cleaner and easier - although much more expensive if you don't already own the gas bottle. But the time savings may make such a purchase worthwhile. When you are doing the palladium salt precipitation, use test strips to make sure you are not adding too much HCl. It will minimize any re-dissolution of the palladium salt.

I am an Italian goldsmith and I am a fan of your channel, I have seen that you have melted the PGMs and you have obtained a crust of impurities, if I can allow myself I wanted to give you a tip to get a clean metal perfect to be purified: Melt and heat to high temperature the metal in question, at this point close the gas tap and give a jet of pure oxygen to the metal, all the impurities will burn including some of the base metals, repeat the process several times and when the metal seems clean enough you can re-melt by adding copper or silver to purify it.

Loved it Sreetips, what great chemistry that was, I’ve never recovered Pd but that was awesome to watch
Archimedes, DaVinici, Merlin, and great Alchemists would be very proud of you my brother!!!! Thank you very much for all the hard work!!!
I just finished watching part 5 and part û just came out! Yay! Beautiful work and buttons! Amazing!!
i unironically cheered when he sawed the part off of the camera stand at the start. convenience over all, after all.
Noticed that it allowed the beautiful close-up of the chlorine tablet crush, like you were right there with him.
That reaction definitely didn't disappoint. That aquamarine blue was so pretty. That was really cool.
That was a beautiful blue it turned with the ammonia from the redish orange... and then back to that yellow gold color what an awesome reaction thank u for sharing the knowledge
Your videos are not less than a master class in PM refining. Keep sharing the knowledge and God bless.
I don’t remember seeing you add the sulfuric? acid to precipitate possible lead contamination....
Science is so cool! Thank you for sharing.
I’ll do it during the refining - this was a recovery
Really beautiful work! I have to admit that you make very relaxing and informative videos- good on you too for sharing your knowledge with the world.
Hmm, that precipitate looks like a goo I've been saving after test-dissolving a bunch of 'silver' plated pins from electronics. I should redissolve it in nitric and see if it's palladium.
That’s awesome. I really enjoyed watching this series. Thank you for sharing.
Third times a charm!
Practice makes perfect!
This process seemed to go very smoothly!
It did shane. I made a couple mistakes. But I got the metal in six, 20 minute videos.
I really enjoy the gas generator precipitated precious metal videos you make. Absolutely beautiful results!
Man that was awesome to see.
I am always amazed with all the different reactions you do.

Always stirr if you put in chemicals to a solution. Safes material and prevents redissolving due to lokal overconcentration
Wow! That precipitation has to be one of the coolest things I've ever seen!
That reaction looked like straight up magic!
Enjoyed the complete series very much. Awesome stuff 💪
From my research Rhodium is soluble in fused potassium bisulfate as well as a solution of sulfuric and hydrochloric acid. Hope that helps!
Voted most visually appealing processing video of the year.
Thanks for the outstanding and well made series.
Amazing work again - that is an incredible looking button of metal. Really nicely done!
I never thought about most of these methods, seems so much cleaner then what iv seen being done
Excellent series Kevin! I've been waiting for it...thanks again!

Jeff, since I moved my stock pot outdoors, I add the waste right back into the stock pot.
How did the solution turn from brick red to blue with ammonia ?
Is the footage missing?
Kindly share the footage 🌱
No, I turned off the time lapse too soon. The blue is traces of copper in the solution. Green is nickel.
Would a spray bottle of saturated Ammonium Chloride be helpful for rinsing the filtrate?
Yes
@sreetips ... What happens when you put a copper wire or pipe into a beaker of Chloroauric acid...?? Does the gold cement out.. Like silver does???
Yes but much slower, and it will be a black powder, not brown
Beautiful blue color
Awesome series. Minus your silver inquartation, what was the final silver yield?
I try to keep silver of my stock pot. Thats why I thought that adding silver was a bad idea
Great series! 👍
I was waiting for the video 😊 Watching now, during working time... don't tell anyone 😉
That was pretty great Sreetips! thanks so much! :)

Have you considered buying a lecture bottle of chlorine gas for this precipitation, or others that can use chlorine gas? It is much cleaner and easier - although much more expensive if you don't already own the gas bottle. But the time savings may make such a purchase worthwhile.
