ABSTRACT:
A lubricant for glass molds and forging dies and for mandrels used in seamless tube manufacture is formed from a mixture consisting principally of gilsonite powder and water, but containing a dispersant and a thickener. When the lubricant is intended for mandrels, sufficient thickener is used to give it a paste-like consistency similar to a light grease.
