Silicone putty-like substance is made by mixing dimethyl silicone gum with a boron compound (e.g., boric acid) and a reinforcing filler, and making sheet stocks of the mixture. The sheet stocks are placed on perforated trays in a heating oven and heated at a temperature of about 350 DEG F. to about 500 DEG F. for several hours. The volatiles produced during heating (cooking) of the sheets stocks are removed from the oven by passing air through the perforated trays in order to obtain high bouncing putty which minimal amount of inferior product.
