A composition and method of preparation are herein described for molten release and parting compositions adaptable for use in glass-forming operations. The novel composition comprises an aqueous dispersion of a mixture of a solid lubricant, a water-soluble silicate binder, a setting agent, and a water-soluble phosphate. A preferred composition comprises a mixture of flake graphite, boron nitride, sodium silicate, zinc oxide and potassium phosphate tribasic.

A stationary pad is disclosed for supporting, holding and protecting a record during treatment. The periphery of the pad is provided with a continuous raised lip, so as to prevent the inadvertent spillage of liquids from the pad onto an underlying surface or the like. Pedestal portions are distributed over most but not all of the area of the pad to raise the record above the surface of the pad so that the lower side of the record does not rest in the fluid which may flow off of the record during treatment. The pad is preferably made of a rubber-like, nonabrasive material having a high coefficient of friction and relatively low electrical conductivity. In one embodiment of the present invention, a central protrusion in the pad is provided on which the record is centered. In a second embodiment, the peripheral lip extends to a height greater than the height of the pedestal portions so as to prevent the record from sliding off the pad.
