Abstract : Physicochemical properties of faience (15-35 percent perlite or 5 percent diatomite) were studied. The addition of 35 percent perlite lowered the firing temperature from 1200 to 980 degrees, lowered the coefficient of linear expansion, from 82.40 to 51.10, and the shrinkage from 3.8 to 3.3 percent. The strength increased. The effect of diatomite was not as pronounced, but the addition of diatomite prevented the formation of cristobalite. In the presence of perlite, large grains and large pores were absent. The presence of mullite was shown at 1200-50 degrees. (Author)
