Abstract

Minerals such as limestone or gypsum, or a mixture of limestone and sawdust or wood chips, are ground in the presence of up to 5 per cent by weight of wool grease. The wool grease acts as a dispersing agent and imparts water-repellent properties to the finished product. Specifications 232,993, [Class 59], 370,878, 569,402, 607,968, and U.S.A. Specification 1,985,076 are referred to.
