Calcium sulfate is a common laboratory and industrial chemical. In its anhydrous form, it is sold as a laboratory desiccant under the name Drierite®. The hemihydrate is better known as plaster of Paris, while the dihydrate occurs naturally as gypsum. Depending on the method of calcination of calcium sulfate dihydrate specific hemihydrates are obtained: alpha-hemihydrate and beta-hemihydrate. Alpha-hemihydrate crystals are more prismatic than beta-hemihydrate crystals and when mixed with water form a much stronger and harder superstructure.

If you have the formula right, and it is CaSO3, then if you heat it, you could drive off SO2 as a gas. That would leave you CaO as a solid.
