Sulfur

Yuck! What's that smell?

When water mixes with the mineral sulfur, a chemical reaction causes a small amount of hydrogen sulfide (H2S) gas is produced. Hydrogen sulfide is the same gas that makes rotten eggs smell bad. That's what smells so horrible!

Keep your sulfur minerals dry and they won't make a stink in your mineral collection! Sulfur is brittle when heated and can actually crack if held tightly in a person's hand.
