This investigation made use of the kinetic adherence test devised by Kapnicky 1 for testing the adherence of molten glass to heated metal samples. This testing apparatus attempts to simulate the conditions of the automatic forming machines of the glass‐container industry. Several commercially pure metals and alloys plus a carbon‐iron series were run for their adherence temperatures. It was found that as the per cent carbon in iron was increased the adherence temperature was decreased. Heat‐treating of a modified brass sample decreased its adherence temperature. Persistence tests were run using tungsten, nickel, and Monel with clear and amber soda‐lime glass. The persistence test consisted of holding the temperature of the metal constant below its adherence temperature and dropping molten glass beads on the heated metal surface until adherence occurred. The amber glass used gave higher persistance values than the clear soda‐lime glass, although the adherence temperatures checked very closely. Monel metal heated to 900°F. gave a persistence of more than 800 molten glass contacts using amber glass at the rate of one glass contact per minute.
