Extract

Plaster of Paris is a general term for gypsum plasters and gypsum cements. Plaster, which has been in widespread use for producing casts of fossils since the Nineteenth Century (e.g., Green, 1832; Ward, 1866), is easily used for making rigid, long-lasting, and inexpensive casts of study specimens, and for making field casts from natural molds. Good general descriptions of the use of plaster are given in Clarke (1938) and Rich (1947), as well as in many recent books on sculpture (e.g., Miller, 1971; Chaney and Skee, 1973; Andrews, 1983), and in various brochures distributed by manufacturers (e.g., United States Gypsum Company, 1987a, 1987b). Using plaster for casting paleontological specimens was previously discussed in works by Quinn (1940), Keyes (1959), Heintz (1963), Rigby and Clark (1965), Rixon (1976), and Chase (1979).
