Mica | Minerals Eduion Coalition
Mica. Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silie minerals, known as sheet silies because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heatresistant and does not conduct electricity.
Gypsum
Gypsum rock is first mined or quarried, then crushed and ground to a fine powder. It then goes through a process called calcining where heat at 350 degrees is supplied to the gypsum powder which removes 3/4 th of the water molecules. Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and other products.
