Abstract

Glasses have been prepared from porphiric sands, TiO2 and MgCO3 and the effect of changing the MgO content on the isothermal devitrification has been studied.

The experimental data suggest that an increase in MgO content increases the devitrification rate owing to a greater aptitude to form nuclei, so that a fine grained microstructure can be obtained more easily.
