Claims5
A honeycomb muffle in a tank surface, having a crown, piers and an inner free surface, for glass melting, comprising blocks of refractory material, wherein at least the crown of said furnace is made of blocks of refractory material, the free surface of which facing inwardly of the furnace is shaped with at least one recess defined by inwardly narrowing projecting ribs, resulting in said recess having a square shape in cross section with regard to the face of the free surface and a trapezoidal cross section with regard to the width of said free surface.
Blocks of refractory material for the construction of tank muffle furnace muffles for glass melting wherein one surface of said blocks is shaped with at least one recess defined by inwardly narrowing projecting ribs, resulting in said recess having a square shape in cross-section with regard to the face of said surface, and trapezoidal in cross-section with regard to the width of said surface.
