3090 degrees is damn close to its boiling point (which is 3265 degrees). So I’m pretty sure it “becomes clear” with temperatures a lot lower than that (it melts at 1414 degrees).

You are talking Celsius while the meme is likely referring to F

When will the US finally use the metric system 😮💨

This ambiguity is what I had in mind when I read “let me be clear”. Though now I get it.

I wonder how they figured that out
Did molten lava touch sand and then they were like 😳

Maybe tektites? Natural glass formed when lightning strikes sand. I only remember the name because they share it with the jumpy spiders from Zelda

When lightning strikes sand it creates fulgerites.
Tektites are meteorites that are formed when meteorites strike.

Oh look there’s a whole Wikipedia page on it

Possibly an accidental byproduct of metal working

I thought you were talking about tektites for a second.

Jules Verne wrote about this in one of his novels. The mysterious island, iirc.

If you spent your days cooking with fire, and your nights watching it and warming yourself, you’d definitely start tossing anything you could find into it just to see what would happen. People did this every day and night for eons.

I think people just experimented a lot. Try enough random things, you’re bound to come across cool chemistry every once in a while. If they figured out how to make really hot fire, that opens the path to “let’s try making various things really hot to see what happens”.
Of, I know basically nothing about [pre]history or human development so I could be way off

Oozy orange blob is the Trump phase.

More like an orangey white like an incandescent bulb, maybe.

how about no

It’s the cooling of silica (really, any material) that makes it a glass, and even then, transparency in the visual wavelength is not automatically certain.

Case in point, obsidian.
neptune@dmv.social 1 month ago
Good example. Obsidian is apparently 70% silica. Iron is apparently what makes it black in color. If it’s thin enough, it is translucent.
If you cool pure silica slowly enough, with impurities to cause seeding, you will get tons of crystals, not a single glass, that won’t be transparent.
