Ready for some geology humor? Of course you are!
While doing my mineralogy homework today, I discovered that there’s a fun mineral, called Realgar. It’s very pretty, which deep red, prismatic crystals. (Prismatic means that it forms with very flat surfaces.)
Realgar is Arsenic Sulfide. Which, if you know your periodic table, you’ll be way ahead of me here…
Yes, that’s the chemical formula. I got a geeky giggle out of that.
Go here if you’d like to find out more about crystalline AsS! It’s actually a lot prettier than you’d think.
I’ve got another geeky geology joke to tell you, but for now, I’d better get back to my homework.
