Abstract

A study was made of the use of nepheline syenite-talc combinations as a flux for producing vitrified bodies at low temperatures. It was found that a mixture of 85% nepheline syenite and 15% talc had a lower deformation temperature than either of these materials alone, indicating a eutectic in the system. Bodies were compounded by adding nepheline syenite and talc, in the ratio found to be the most fusible, to clays and flint. Bodies were developed that had less than 0.3% absorption in the firing range cone 02 to cone 2. These bodies had good color. Their modulus of rupture values ranged from 7000 to 10,000 lb. per sq. in.
