Abstract: A mold cavity defining structure includes inner wall means defining a glassware forming surface which is adapted to contact the molten glass and to thereby remove heat from the molten glass. This inner wall means also defines a second surface, spaced outwardly from the first, and which can be cooled so that heat is adapted to be conducted outwardly from the first surface toward the second surface. The mold cavity defining structure further includes outer wall means spaced from the inner wall means and defining a third surface which is spaced outwardly from the second surface of the inner wall means to define an internal chamber of generally annular shape therebetween. This chamber is filled with a porous metal filler material, comprising generally spherical particles which are brazed or sintered to one another and also to the second surface of the inner wall means, but which brazed particles also define interstices therebetween to achieve a high degree of porosity in the filler material. Means is provided for passing a coolant such as air through the porous metal filler material, and preferably said coolant is caused to pass through the chamber in a radial direction, from adjacent the outer boundary of the filler material, to the inner boundary thereof. The filler material preferably comprises generally spherical Monel beads having a diameter of approximately 3/32nds of an inch, giving the brazed filler material a density of approximately 65% that of the bead material.
