Abstract

317,672. Lefebure, V. Oct. 22, 1928. Addition to 236,695. Plaster.-In a modification of the process claimed in the parent Specification for the manufacture of plaster from natural mineral anhydrite, the components of double salts instead of the double salts themselves are added, the proportions not being limited to the proportions in which they occur in the double salt. In an example, up to 2 per cent zinc sulphate and up to 4 per cent potassium sulphate are added to the anhydrite.
