This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

But where does calcium fluoride come from?..

[–] Omgpwnies@lemmy.world 13 points 2 days ago

If you bring calcium within sniffing distance of fluorine, you get calcium fluoride... just make sure you don't have anything else close to the fluorine, including you.

Also, it's basically just mined and purified as-is, it's pretty common.
