Waste Glass as a Flux for Brick Clay.
NTIS: PB 214 271 :9 pages
Work in this investigation was undertaken by the Bureau of Mines to demonstrate how waste glass might be utilized to lower the required firing temperature and firing time of structural clay products. Mixtures of waste glass and common clays were formed by stiff-mud extrusion and fired to the temperature required to produce a body having 6 to 7 percent absorption. Substitution of glass for one- half of the clay in a red body reduced the firing temperature 500 deg f, which made possible a 30-percent increase in production; in a tan body, the firing temperature was reduced 400 deg f, which made possible a 23-percent increase in production. Work done in cooperation with the University of Alabama.
