Photo Gallery of Sulfates

Sulfates are weird. Lots of them are water soluble, many are deliquescent and some loose water. That is not a way to make proper minerals! I like Barite, though. It's pretty, common enough to be available, yet not trivial to get in good pieces, and practically insoluble in water.
