ABSTRACT:
A protective liner article for wet scrubbers and the like consists of a cellulated glass block of corrosion-resistant material, such as PENNGUARD.RTM. Block, a cellulated borosilicate glass, and a sheet of glassy, corrosion-resistant material which can be and preferably is corrosion-resistant glass such as 7740 Pyrex.RTM. bonded to a face of the block. The sheet is fused to the cellulated borosilicate glass block by applying radiant heat to an outer surface of the sheet while keeping the body of the block at a temperature below the degradation temperature of the block until the sheet bonds to the face of the block. Preferably, a finely-divided frit is applied to the surface to which the glass is bonded, filling interstices of the surface of the block, before the sheet is placed on the block.
