Thermal effects of casting materials

Abstract

A number of variables are important in controlling the exothermic reaction of cast materials. These reactions can reach temperatures capable of producing burns. The most important variables are plaster type, cast thickness, and the presence of externally applied materials, e.g., vinyl pillows. Moderately important factors are dip water temperature, humidity, room temperature, and used dip water. An insignificant factor is cast-padding thickness.
