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.
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.
Glassblowers: thanks Obama

So it doesn’t become “clear”, it literally vaporises.
You are talking Celsius while the meme is likely referring to F (you can tell because Obama)
When will the US finally use the metric system 😮💨
Anti Commercial AI thingy

Maybe tektites? Natural glass formed when
lightningmeteorites strikessand. I only remember the name because they share it with the jumpy spiders from ZeldaWhen lightning strikes sand it creates fulgerites.
Tektites are formed when meteorites strike.
I am sorry for insulting your people
Right. Now don’t do it again!
Hi! You included a link which is really difficult for mobile users to tap. Here is a much longer and more tappable link.
I am not a bot, and this action was performed manually. I recall that there was a bot for this on Reddit. Does an equivalent exist on Lemmy yet?
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.
first it becomes glowy orange tho
Oozy orange blob is the Trump phase.
