A few years ago I stumbled onto something called purple gold and I really wanted to buy a pure purple gold ring. However, I was devastated when I found out that it didn't exist...so I decided to try and make one myself.

As someone who uses sandpaper a lot, I can almost guarantee that the gold that you lost simply just got stuck in the sandpaper. Soft metal is very good at clogging sandpaper grit and with as much sanding as you claimed to have done, I'm genuinely surprised you didn't lose more than you did lol

I'm pretty sure he'd have had to have recovered the gold from that. It's pretty simple if you just burn the paper. Getting the sand out would be harder though.

[@PlastikGatz]

@@GameDesignerJDG and you also have to remember that a lot of that “sand” is actually aluminum oxide. I’m no chemist, but I would think that introducing other chemicals into the mix would make recovery a bit more challenging lol

Fun fact: in the semi-conductor industry, this alloy is known as “purple plague” because it’s extremely detrimental to parts. Basically, if gold and aluminum contacts touch at high temp, some purple alloy naturally forms. This alloy is both brittle and a poor conductor, leading to electrical or mechanical failure. It was a big issue for a while, and Al and Au are some of the most common contact materials in chips. So yeah, fun facts for ya. Edit: Wow, this blew up, haha.

I think some mid 4 figures of gear and material (excluding the gold) to start you off.

[@philouzlouis2042]

Hi NileRed, Nice video. I have three, probably important, comments for you :o) I hope you will like it (at leat it may interest scientific peoples, enginers and chemistry educated peoples, or readers). 1°) About your gold amount disappearing; you are right gold when heated vaporizes and some is lost not only litteraly but effectively into fumes... so you are "totaly sane" and absolutely not crasy; your results show this effect quite obviously (and yes dramaticaly). Not many knows this but gold is a "noble" metal; and as such molecularly despite its weight and density; it ressembles by many aspects to mercury metal or noble gases; when heated; it sublimates partly thus long before melting point is reached some is lost in the air. 2°) Annealing at 600°C is one thing; but often in industial processed it is made several times in sequential mode; so heating, cooling, reheating, recooling, etc.; I'm quite sure that your pink-lilac colour will improve upon cycling more (not a single time (like what you did), but several times) and also by checking the form of the cyle (speed of heating, time of plateau, speed of cooling). 3°) The bubbling of Ar gas into the melt (or N2 gas - that is cheaper) a bit like what is done in chemistry with fluids to degas them is a good option; just like the ultrasonic (or vibrations like some cements, plaster, plastic for molding)... but Did you consider reducing the overal pressure; it also degas things more and faster; some use a depressurization chamber for cements, plaster or plastic molding; of course taking into account the volatility of some ingredients or solvents; here despite aluminium and gold are metals and melting point should remain almost the same; the oxidizibility of aluminium should be reduced in lower pressure; but volatility and loss of gold will be worse under reduced pressure than your 5% loss :o(. Kind regards PHZ (PHILOU Zrealone from the Science Madness forum)

[@PsRohrbaugh]

Remember that aluminum immediately passivates into aluminum oxide, so all bulk "aluminum" contains surface layer of aluminum oxide. You need to use chemistry magic to add PURE aluminum to the liquid gold with no surface layer. Perhaps suspended in a liquid. Add the liquid to the crucible with bubbling argon and slowly warm up the crucible evaporating the suspended liquid. Now you have pure aluminum you can add gold to. You're also sanding / polishing with aluminum oxide. This is why it remained silver. Do this: mix pure aluminum with no aluminum oxide, pure Gold. Bubble some argon. Pour into a mold, and put DIRECTLY into a furnace and do not let it cool below 600C. Let it sit at 600C for 24 hours, and cool down to room temperature over the following 24 hours. Then polish with stainless steel, stone, or some non aluminum compound. I am going to do my own work with my goldsmith friend but you have much more resources. Finally, you say you don't knowing where the gold went... But you were sanding for 10 hours (!) multiple times (!) and you ONLY lost 5 grams?

As I had previously worked in a gold refinerary doing the Aqua Regia making 99.999% or Five Nines (sometimes higher) I was curious as to the process of making the purple gold. The sales team couldn't tell me the exact process but there had been a patent taken out on it.

[@oculusangelicus8978]

The loss of Gold was almost certainly connected to the Sanding portion of your working with it. You likely have a significant amount that is still in the matrix of the sandpaper you used, and there is also a loss of gold in dust form through air movement. I would suggest using a wet sanding method in a container or water where the gold dust will be collected in the water of the container. I also saw when you hammered earlier pieces of purple gold, small pieces flew off due to the brittle nature of the metal. and because gold is so heavy it doesn't take much gold loss to amount to 5 grams. but it is still a lot of gold to lose. so, if and when you decide to work with gold alloys again, make sure you are using a vacuum with a filter that can collect the gold dust or better yet just sand the gold inside of a water filled container to that all of the abraded gold can be kept from being lost. Also not go hammering any of those pieces anymore because metal does form into crystals when freezing and if it is brittle like the purple gold, you made hammering it will cause the crystals to break apart and some of them will shatter. to get an idea of how to keep all of your gold in a form that will minimize loss you should watch Sreetips and his gold refining videos, but it does little to show how to keep your dust to a minimum. Work your gold in a different medium than air, work it in water, or rather sand it in water. Your Dremel can be hooked up to a flex shaft and you can do your shaping of the gold in water as well. this will prevent loss but may not stop it all. when working with precious metals, jewelers have to accept a certain amount of loss, and this loss is figured into the price of the Jewelry being made. Sure, jewelers collect as much dust and granules of the precious metals they work with but it can never be truly all accounted for This is just the nature of the world we live in.

[@eigentensor]

Yeah it's absolutely hilarious that he says he has no idea how he lost it! The whole video long he's smashing stuff and pieces are flying off, tons of it going into the sandpaper, random blobs splashing out of the crucible, ...

​@@takumi2023 honestly probably no other way to do it, with metals you usually are able to plastically shape it, but this thing can't even be bent😅 closer to working with a stone than to metal

[@iankrasnow5383]

​@@RENO_K Not all metals are malleable or ductile, including a lot of steel alloys. They can only be shaped by grinding and cutting. You can't reshape knife steel after it's been quenched for instance. For some brittle metals with a super high melting point, like tungsten, you can't even really cast them- any material you would use as a mold would melt too. Tungsten is actually formed by sintering. Metal powder is put in a mold or built up in layers and each one is melted or heated to near its melting point with a laser and then it fuses to a single piece. But this limits the applications for the metal since it will have very small, jagged crystal structure and be brittle.

[@Cjoudan]

I took jewelry in high-school. We used a wax reverse casting. And then we measured out the metal we need in a crucible. We then had a sort of centrifuge arm that held the cast and crucible and would spin around forcing the liquid metal inside. Sadly I don't know how to do that without a whole chamber filled with Argonne to for the purple gold.

I come from a family of Jewelers with an over 50 year history of being in the business. Purple gold is not the only interesting color you can find the alloy in. In the early 2000s Green Gold suddenly became very popular for a brief time. Rose gold has been very common place for a long time as has white gold. The most striking color of it in my opinion is an alloy of either gallium or indium. It looks kind of like Cobalt. When I heard you wanted to break that bar down with a hammer my heart skipped a beat. Gold is incredibly mailable, the purer the bar the soft it is.
