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.

teft@lemmy.world on 03 Apr 2024 15:09 collapse

Case in point, obsidian.

neptune@dmv.social on 03 Apr 2024 15:14 collapse

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.

I wonder how they figured that out

Did molten lava touch sand and then they were like 😳

It’s like minecraft.

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

brisk@aussie.zone on 03 Apr 2024 19:57 next collapse

Oh look there’s a whole Wikipedia page on it

en.wikipedia.org/wiki/History_of_glass

Possibly an accidental byproduct of metal working

Ha, nice reference

Hule@lemmy.world on 04 Apr 2024 03:10 next collapse

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

Leate_Wonceslace@lemmy.dbzer0.com on 04 Apr 2024 03:36 next collapse

I thought you were talking about tektites for a second.

tektite@slrpnk.net on 04 Apr 2024 03:51 collapse

When lightning strikes sand it creates fulgerites.

Tektites are formed when meteorites strike.

brisk@aussie.zone on 04 Apr 2024 07:26 collapse

I am sorry for insulting your people

tektite@slrpnk.net on 04 Apr 2024 08:35 collapse

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?

NeatNit@discuss.tchncs.de on 04 Apr 2024 12:04 next collapse

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 course, I know basically nothing about [pre]history or human development so I could be way off

Olhonestjim@lemmy.world on 04 Apr 2024 12:23 collapse

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.

3090 degrees is above its boiling point (which is 2950 degrees).

So it doesn’t become “clear”, it literally vaporises.

neptune@dmv.social on 03 Apr 2024 15:58 collapse

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 😮‍💨

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

first it becomes glowy orange tho

ivanafterall@kbin.social on 03 Apr 2024 17:56 next collapse

Oozy orange blob is the Trump phase.

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