Abstract

A method of coating a tool surface to render the tool fire and heat resistant which includes the steps of providing a tool having a surface utilized in connection with high heat and fire encountering applications, providing a composition which includes from about 3 to about 8 parts by volume of Sagger's Clay, from about 3 to about 8 parts by volume of a soluble alkali silicate, from about 3 parts to about 8 parts by volume of granular mica in a laminated silica mineral form, and from about 1/2 part to about 2 parts by volume of water, applying the composition to the working surface of the tool which is intended for high heat and fire encountering applications, and allowing the composition to dry on the surface of the working tool thereby to provide a heat and fire resistant coating thereon.
