ABSTRACT:
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.
