additionally, isnt glass a semi natural occurring substance? Im pretty sure ive heard of lightning strikes in deserts/sand that created glass.

I never heard of that but TIL it's called Fulgurite https://en.wikipedia.org/wiki/Fulgurite

Glass is also created by volcanoes; we call that obsidian.

Interesting, there is a community for sea glass..

It's the dulling process that sucks.

I once got a stick stuck in my foot. Maybe we should ban those.
