Abstract
An improved composite material provides surfaces for handling hot glass charges and newly-formed glass articles without detrimental marring or marking of the same. The surface is formed on a relatively smooth metallic substrate by applying a primer coating of a first silicone resin to the substrate, applying a solventless second silicone resin binder coating over the primer, depositing a layer of granular heat-resistant carbonaceous material over the binder and allowing the binder to embed the carbonaceous material, and heat-curing the binder to provide a lubricated durable wear-resistant surface for handling hot glass charges or gobs as well as newly-formed glass articles.
