Former jeweler/caster; the other reason you preheat the molds is if there is ANY moisture when that molten metal hits it, it could very well be released as steam and blow through the metal making a small “explosion” of molten metal from the pressure.

[sakaraist]

mentioning nilered and the manhattan project in the same sentence is dangerous. For years, i've been sure he's one bad day away from a villain arc, except instead of john wick it's war crimes. He's simply too powerful.

If Nile was a publishing scientist, he'd have well over a hundred papers to his name by now. It's NUTS how incredibly well-researched and thorough his experiments are, considering how much of what he does is quite literally cutting-edge basic science in topics that even most people in academia don't mess with.

"You probably shouldn't use a nuclear reactor for large scale alchemy"

Fine, I'll continue working on my desktop-scale particle accelerator /j

[river]

By far one of my most favorite videos from NileRed. I absolutely love the audacity to just go "fine, I'll do it myself" with this one

58:54 He did NOT use borax. He talked about why it would be used, but it can’t be used on this process, since it mixes with aluminum.

Gold is very unusual as far as heavy metals go, in that it's not toxic at all, because it's chemically almost completely inert.

[spvillano]

When Germany invaded Denmark in 1940, de Hevesy dissolved the gold Nobel Prizes of Max von Laue and James Franck in aqua regia to prevent the Nazis from taking them.
After the war, he precipitated the gold out of the acid, and the Nobel Society recast Franck and von Laue’s awards from the original gold.

With his color issues, I'm willing to bet that it's all an issue with crystal phases. That would explain why annealing it changed the color. Also, his hydrogen problem very well may be why others claimed that the alloy was so brittle, as hydrogen is a royal pain in the ass in causing embrittlement of metals (although, that's usually over time as the hydrogen penetrates the metal).

I assume that most of the missing gold is a super fine dust embedded in the sandpaper directly. There's a reason companies that work with precious metals will incinerate that sort of stuff at yend of their useful lives.

I think it's common in all the Scandinavian, and probably some European countries, to use the comma as a decimal point. That said I have started more or less using just a period as it makes working with computers a lot easier

[ODST_Republic]

4:08 yeah, the reason he wasnt able to get info for the gold, is because google search proceess has gotten so bad you have to go in past several pages to actually see the things you want to see since the first couple of pages are biased or advertisements

[AtomicDream]

You genuinely clear up so many misconceptions about nuclear power in a world that (for the most part) doesn’t understand it. You inspire me to work in the nuclear power industry.

37:54 to explain that sanding segment the most likely answer is oxidation. When he scrubbed the top layer off the heat from the rubbing immediately caused the next layer to oxidize again leaving behind that silverly aluminum oxide

It's because purple gold is an intermetallic compound rather than an alloy. A mixture of 75% gold with 25% copper makes an 18k red gold that also can also have brittleness problems. If it is repeatedly heated to annealing or soldering temperature and allowed to air cool it develops intermetallics that build up, dramatically reducing the ductility and malleability of the alloy. So for an 18k red gold it either must be quenched in water or alcohol above 700°F or mixed with a couple percent silver to eliminate this tendency to develop brittle intermetallics.

I loved the 1st purple bar ingot. Those holes gave it character.

16:10 actually when they are panning they are looking for little gold nuggets and flakes among the gravel, sand and clay. the gold they are looking for is shiny rather than the dull microscopic dust we are looking at here...

8:42 comma as a decimal separator is more of a European standard.

[legendofayda]

Comma as a decimal is relatively common in the EU, but they’d understand what you mean if you use a decimal in its place. They really only use commas when referring to prices though. In universities or other settings, they’ll typically use decimals.

[proosee]

The gold bar was from Switzerland, so it makes sense they used decimal comma - almost entire Europe, South America and half of Africa is using decimal comma instead of decimal point. Separators for 3 digits vary from country to country but usually it's apostrophe or space.
