An improved kinetic test was devised by which the adherence of molten glass to metal may be evaluated. The results were expressed as the highest metal temperature at which the molten glass beads do not adhere. The variables of the test investigated were temperature of molten bead, height of fall of the molten bead, and slope and surface roughness of metal sample. Several types of glass mould lubricants were investigated as to their effects on the adherence temperatures and as to their persistence on heated metal surfaces. Several silicone lubricants were found to have high critical adherence temperatures while the graphitized oil base lubricant gave the best persistence.
