ABSTRACT:
A reducible glass lubricant on a metal workpiece provides a duplex film during hot working of the workpiece. A silicate glass powder which contains from about 3 to 50 mole percent of an oxide of bismuth, tin or copper is used for the reducible glass lubricant. During preheating in a preheat furnace the glass lubricant is reduced to the duplex glass film.
