The sheet stocks are placed on perforated trays in a heating oven and heated at a temperature of about 350.degree. F. to about 500.degree. 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.
