Gypsum Rock Is New Building Material In Most American Homes

The video tutorial explains the significance of gypsum as a crucial building material, second only to lumber. It details the mining process, where gypsum is extracted and processed into a fine powder. The powder undergoes dehydration and rehydration, unique to gypsum, allowing it to return to a rock-like state. Finally, the video describes the production of gypsum board, where the rehydrated gypsum is sandwiched between paper sheets and formed into continuous panels.
