Abstract
A game call friction material is disclosed. Airfloated clay powder is heated to a temperature of greater than approximately 1112° F. to form a calcined clay powder that is then mixed with water and a carrier such as plaster and set to form a solid mass. The volume ratio of plaster to calcined clay in the solid mass is approximately 150:1. The solid mass preferably has a cavity with a second mass of calcined clay and plaster disposed therein. The volume ratio of calcined clay to plaster in the second mass is approximately 3:1. The solid mass is rubbed against a friction game call, depositing calcined clay particles and plaster particles thereon. The calcined clay particles form friction layers on the relevant surfaces of the friction game calls. The plaster helps to dry the friction game call surfaces and to form the friction layers on the friction game call surfaces.
