In a float glass chamber, particularly in a region operating at higher than usual temperatures, integrity of the bottom structure is sustained by employing wedge shaped bottom blocks that are maintained in compression by externally applied mechanical forces. The arrangement permits the use of a bi-layer bottom construction with a high alumina upper course and a clay bottom course.

Compressed, wedged float glass bottom structure

A lid construction for a heating vessel. Discrete insulating members are supported by water cooled pipes above the vessel. The cooling pipes fit into grooves along the vertical side walls of the insulating members. Each member has a support independent from the supports for the other members so that an individual member can be removed within having to remove additional members.
