The pores are sized on a molecular scale, especially if your alloy is well and truly mixed. You may need to an electron microscope to compare the pre-HNO3 treated electrum and post-HNO3 treated gold. I would hazard a guess that the gold powder from precipitating the chloroauric acid and the silver powder cemented out of the silver nitrate solution are on a molecular scale for particle size. Further, I speculate that the gold powder could be compressed into chunks similar to when other metals are sintered into shapes because of gold's "self-welding" property. They would make amazing paint pigments although expensive. Have you ever allowed the chloroauric acid to evaporate making pure gold crystals? The white precipitate could be lead sulfate or silver chloride or nitrate. You use a shot of H2SO4 to precipitate the lead; some silver could also be carried over and rendered into an insoluble salt.
I'm an oil painter, and I once ground 23.5k gold leaf into linseed oil and made a gold paint, a sort of crude shell gold, which is what the old masters used for their icon paintings. Truly though, when it gets broken up, it really loses its shine, and when you paint it on, it's really hard to shine it back up unless the paint is very dense in gold content. I plan to experiment more in the future, but I'm thinking it's probably better to just lay down some gold leaf for the vast majority of situations in which a golden look is required. Also, if you're actually looking to paint something that looks like it's made of gold, it's paradoxically better to simulate this with a variety of pigments like blue ridge yellow ochre (which looks kind of like the inquarted gold, though there's no gold in it), as well as cadmium yellows/oranges, and my favorite, naples yellow.
Fantastic as always. One gets the sense that you hide nothing. You're open and informative, pasing along all you know. It's a nice change from those that feel they have to keep things secret as though they are the only ones that should know. Huge kudos to you. You've become a YT favourite of mine for sure. 👍👍👍
As others have already commented, the honeycomb structure is probably too small to see. Crystal size can be increased by rate of cooling when solidifying the inquarted gold, since your inquarted gold is poured as shot into water the solidification is almost instantaneous and hence the crystal structure is very small. I would hazard a guess that a very slow cooling rate of the inquarted gold would yield much larger pores. If that were the case, the larger pore size could also make the silver extraction more efficient 🙂
I just so happen to have within arms reach a couple of dry troy ounces of double refined (SMB & Oxalic Acid) gold in a small beaker and my USB microscope. I can see small holes throughout the pieces. Nothing I would call a honey comb structure but holes nonetheless. Perhaps a stronger microscope would reveal a more defined structure. Cool stuff Sreetips...
@@sreetips I actually might purchase some to help remove a stump that is in my yard, I wonder if it works as well for that purpose as it does for gold refining!
I think it's notable that the inquarted gold has formed these little nugget like clumps that look nearly identical to some natural nuggets. I wonder why . As for seeing the honeycomb structure, you probably just need a more powerful microscope . I'm very curious to see a drop of the gold in solution on a slide under a very powerful microscope. 🤔 Cool video, man . Thank you 👍
If you want to see interesting structures in gold, Try melting some into a button. Now, take that button and dissolve the top (outer) layer. If you have done this, you should see with your naked eye, a crystalline structure appear on the surface of the button. Turning the button in your hand, you will see light reflecting off the crystals in very unique patterns. Using a microscope on this you may see it better.
That silver cement process is incredibly fascinating. These chemical processes you do with precious metals helps me to better understand the chemistry of geological formations of metals in their various states. Like how gold is made in the earth and then gets deposited in different places. In ore, nuggets etc.
@@enkidu9705 , God made the gold. I'm talking about the geological data that talks about gold coming from deep within the earth in lava and or geothermal fluids that deposit gold in rocks or in nuggets near the surface. I never understood that gold could be in solution until I saw. Sreetips do it . Then it mad sense to me how gold could be in different forms .
Do you have a formula or price list that you use to help you in determining how much to pay for karat gold from garage sales and other places you find items? I would image it has something to do with the karat and weight of the item. Also, do you happen to know your total expense amount for a processed gram of gold? Thank you!
320th! I can’t watch enough of your channel! I don’t know if it is the money that comes from your purification, or the process? I decided, IT IS BOTH! Roger in Pierre South Dakota
You can’t fool me your that cleaver Land Shark .. sreetips you know and I know what that looks like lol that looks like a glop of excrement. I do love how you are fascinated with how your gold looks in every stage of refinement. Can’t help but laugh at your nerd ness don’t get me wrong ! It’s @ good thing! Thank you for the upload!
That microscope doesn't seem to have reasonable magnification. You can get cheap USB microscopes with magnifications of 1000x and more for less than 30 bucks on amazon.
If your ring were a lower karat it would have been something more like reduction guilding which is where you allowed to work for a short period of time as a surface treatment to give it the appearance of 24 karat. Have you ever done anything like that? It might be something to bring your experience to bear on and perfect the details through your vast knowledge so we can all get another little piece of the puzzle to add to our understanding of all things golden that would also be very interesting to see at the microscopic level
It's not a very good idea putting your Go-Pro camera inside of your fume hood while you're dissolving the gold. All those corrosive fumes will get into the camera and corrode the electronics inside the camera. If you insist on doing so, at least put the camera into a water-tight (underwater) plastic case.
Thanks for the awesome video!! But I have to know, when you pour off your way solution rinsewater how much gold is running off? Maybe next time, dump your Waste solution into a clean beaker let it settle, draw off liquid, melt to button and weigh? I know you eventually get it when you process the waste solution, just curious. Thanks again watch all your videos very much appreciated.
Looks an awful lot like a little gold turd to me at that low magnification. How tight can we really get in on that? 4 min Not exactly homogeneous is it?
I'm so confused; any thoughts: If the inquartation gold is poured into plates or just placed into filter baskets and copper plates or filter baskets were alternated. Then if the series connection of plates or baskets between the different potential plates or baskets suspended in electrolyte would create an energy producing battery. Between the anodes and cathodes the silver will move from the gold through the electrolyte and attach to the copper plates. The completed reaction purifies the gold while producing energy as electricity as opposed to it as heat. I wonder how much potential electrical energy each cell of a silver gold - copper battery compares to a lithium iron phosphate 3.5 volts per cell. And I wonder what if nitric electrolyte were substituted with dry electrolyte? I really like thinking about the silver cell too. Mostly I wonder about how the power supply can only control the voltage. In this silver cell system the current flow is limited to the resistance. Apparently, a relatively low voltage is desirable and the amperage becomes a product of the resistance of the electrolyte. What would result from maintaining the low voltage but increasing the current amperage? Would the crystal size differ? Would the speed and deposition rate change? How would placing a resistance load into the circuit on either the anode or cathode pos/neg wiring control the current amperage? Would the increase in the circuit amperage best be controlled by multiple LED's or resistors twisted together in parallel or would a variable potentiometer like a radio volume pot be better? Since increasing the electrolytic silver cell amperage while maintaining the low voltage provides more control of the production I wonder what effect occurs when decreasing the cell voltage to 1.5 volts while increasing the circuit amperage / load to 5 amperes produces? ✌️♥️👍
you need to place it between two pieces of glass so it is flat, the 3d structure otherwise causes the camera in the microscope to fall out of focus.....
A note about the "honeycomb" structure you were looking for in your nitric acid etched alloy sample. At the moment of solidification of the alloy, silver and gold were thoroughly mixed: gold atoms scattered among silver atoms). And in this state it suddenly "froze". Therefore, the structure of gold, even if it resembled a honeycomb, the characteristic size of this structure would be in the order of the distance between gold atoms in the alloy (i.e. in the order of nanometers), with no chance of observing it in an optical microscope. You would need to use an electron microscope.
The college has an SEC. I know the math professor. He may be able to hook me up with the science professor so we can look at it properly. I’ll make a video of it.
Hi sir, where can I purchase real gold filled quality jewelry? Do you have a trusted source? Most places I contact only offer solid or plated.. I want a custom Cuban link chain made in rose gold, 10-12 mm thick and 18-20 inches. Please help thanks! I’m located in south FL
Hi sir.... when I dissolve 10 gram of gold powder to refine it by aqua regia there is some of yellow precipitate appears in solution .. please what's this yellow precipitate... Thanks my friend
You might remember I left a comment about a week ago about the video continuously buffering and not playing? Well, this video was doing that tonight, I changed from firefox, to chrome & it came up, no problems. Have you thought of uploading your videos to Rumble, as well?
Mike, you don't have a real micro-scope there. There is not enough magnification to see waht you're looking for. Where did you get that useless piece of junk ? Ali-Baba ? Cheap Chinese crap ? You're going to need 45 X or more to catch what you're looking for.
My guess on the mystery chunk is a gemstone. As to what it may have been, your guess is probably better than mine. As for what that reddish discoloration after 2nd AR refining, I wonder if there may have been enough free acid in the solution to start pulling gold back....?
May have been an opal. The red - that was just baffling. Stuff like that never happens. Only when I’m shooting video. Like the refining gods are frowning.
Hello Sreetips, I have little question. Some time ago I see one of your video where you talked about something like "why collecting gold" and not other metals. I remember that you show it in periodic table but I am unable to find this video again. Can you help me please?
You said that you were pouring waste into the waste container but, you poured some gold oxide with water and with HCl into the container. Very pretty colors but check out that waste container for brown stuff, I'm sure there's some in there!
what the hell is that reddish contaminant? it crashes out of solution with the gold when you use SMB, and it gets dissolved in aqua-regia but not in pure hydrocoric, or am i getting this wrong?
They came over when I poured the molten inquarted gold into water. They survived all six nitric boils. And the aqua regia boil for the first dissolution. I think it may have been an insoluble mineral. Maybe opal.
Carson makes a nice 100x-250x handheld microscope for around ten to twenty dollars that could do a way better job at showing the finer details. It also comes with a slide for the smaller stuff.
Awesome video. Thank you for more insight on the process. I’m waiting on a colorful metaphor to slip in, but I get the desire to have a PG video for professionalism.
Sir, that is smart, that you have a refrigerator in your lab. This way the family refrigerator will not get chemical containments. Well, I gotta get one too. Lol 👍👍
Sreetips, if you would be up to it, get ahold of a high powered microscope, either a University, or a jeweler might provide the opportunity. That would definitely be really awesome to see, and I think you would absolutely agree! Great attempt!
Hello sreetips folks. Hello Mr sreetips. The time in Norway is yust now 05:45.🇳🇴 My wedding band is yust over 10 gram. Custom made, and a little cross, in white gold. I think is unik. Also 14 k. Thank you for a informative clip. Nice ways to start the Day. God bless you both sir, and have a Nice Day.
It was Worth the try Sreetips, but watching it I knew straight away you werent going to see much, it seems you used something thats more like an oversized jewlers loops rather than a proper microscope. The magnification you had looked very small. You would im guessing easily be able to see the honeycomb structure if you had a proper laboratory microscope, that has a 100x objective and a 10x eye piece, 1000x total. you would probably still easily see it at 100-200x magnification. Its just something I thought id recomend if you are intested enough to buy one, youd pick up a half decent one for $100-300, but because what youd be looking at is solid youd need to buy a mini spotlight with a benable neck kinda thing that you could shine in from the side to give you enough light to see it.
