The addition of silica to enamel in the form of a readily fusible silicate, such as sodium silicate, lowers the smelting time and temperature required to bring about complete solution of the silica. Enamels in which all the silica was introduced in the form of quartz, although apparently completely smelted, still contained large quantities of free silica, while enamels of identical analysis in which sodium silicate was the sole source of silica contained, after smelting, no free silica. The presence of this free silica in an enamel affects its workability and acid resistance.
