Five common frits fired at cone 03 (1950F)

Thursday 16th October 2014

Five common North American Ferro Frits fired at 1850F on alumina tiles (each started as a 10 gram ball and flattened during the firing). At this temperature, the differences in the degree of melting are more evident that at 1950F. The degree of melting corresponds mainly to the percentage of B2O3 present. However Frit 3134 is the runaway leader because it contains no Al2O3 to stabilize the melt. Frit 3110 is an exception, it has low boron but very high sodium.
