History. In the 1890s, gypsum manufacturers perfected a method of strengthening plaster by adding a retarder, which controlled the setting time, thus creating a viable competitor to traditional lime plaster. Because gypsum was plentiful, and available at a relatively low price, and because the manufacturing process was so simple, new firms flooded and fragmented the market, placing constant ...
