Glass product manufacturing apparatus and method of manufacturing glass product

A glass product manufacturing apparatus comprising:

• a melting vessel;
• a support grating configured to support an outer wall of the melting vessel and offsetting a force of the melting glass pushing on the outer wall, the support grating comprising a plurality of openings through which radiant energy emitted from the outer wall passes;
• a cooling module attached to, and in contact with, the support grating and configured to cool the outer wall of the melting vessel, the support grating provided between the cooling module and the outer wall, the cooling module comprising:
• a cooling medium inlet through which a heat transfer medium fluid is received within the cooling module;
• a cooling medium outlet in fluid communication with the cooling medium inlet, wherein all of the heat transfer medium fluid that exits the cooling module exits through the cooling medium outlet;
• and a recessed portion defining an opening;
• and a support frame detachably fastened to the support grating to limit a movement of the support grating, the support frame comprising a beam structure and a support structure, the support structure extending laterally from the beam structure, through the opening of the recessed portion, and to the support grating, wherein the support structure is detachably fastened to the support grating and applies a force to the support grating-, wherein a difference in temperature of the heat transfer medium fluid entering through the cooling medium inlet and exiting through the cooling medium outlet is within a range from about 70 C to about 150 C.
