Gypsum boards give a smooth, continuous surface to which you can apply paint directly. Gypsum has the property of balancing the building’s indoor temperature and humidity. Gypsum is a low-emission building material that provides excellent thermal and acoustic insulation.The gypsum formed irregular shaped masses within the limestone. The resulting rock is known as the Madison Limestone formation, or locally as the Pahasapa (Black Hills) Limestone. The gypsum masses were unstable. They grew and shrank as they absorbed and expelled water. This pressure fractured the gypsum and surrounding limestone.This is because gypsum is far more soluble than limestone and so dissolves more rapidly. Sinkholes also occur over salt deposits, commonly in areas such as Cheshire where brine has been extracted, making it difficult to separate naturally formed sinkholes from those created by man.When plaster of Paris gains water, it turns into gypsum and therefore hardens, which is responsible for the setting property of plaster of Paris.
