Hello, I was wondering about the safety of a specific mineral, Selenite. From my research, I have read that selenite is the crystalline form of gypsum, which is hydrous calcium sulfate. I was wondering if I were to grind selenite and mix about a 1/2 tsp with 3 ounces of water and spray around my home, is that dangerous? Also will the grinding process be dangerous if any small amounts of dust are inhaled?
