Abstract
Abstract A lubricant composition comprising water, graphite, an organic thickener, sodium molybdate, and sodium pentaborate. Other additives are sodium bicarbonate, ethylene glycol, or mica. The composition is effective in the hot forging of metals, is virtually non-flammable, and generates very little atmospheric pollution during use.
