The Bureau of Mines produced building brick of good quality in an investigation designed to explore the possible utilization of high- glass fractions of municipal incinerator residues in the manufacture of building products. Common clays, lime, and sodium silicate were used as binders for the nonplastic residues. Test bricks were formed by dry pressing, soft-mud molding, and stiff-mud extrusion. A run of standard-size face brick, dry-pressed and fired in the west Virginia University coal research Bureau pilot plant, demonstrated that sw-grade glass-clay face brick can be produced on a commercial scale without difficulty. A cost evaluation made for production of the brick showed an estimated cost of $42.13 Per thousand bricks for a shuttle kiln plant and $28.70 Per thousand for a tunnel kiln plant.
