ABSTRACT:
Disclosed is a glassware forming mold of three-layer construction including first and third bodies, one of which is to be in contact with a portion of molten glass fed, for controlling the heat transference in a glassware forming process. A second central body is located between said first and third bodies and is comprised of a metallic alloy which melts approximately at temperature between about 375.degree. C. and 550.degree. C. corresponding to a working temperature of the molten glass, provides a solid-liquid state, to control the heat transference from the molten glass to the first or third bodies and from these to the environment during the glass forming process, whereby the glass distribution within the mold is improved.
