Bubbles--a glass-ceramic plague.

The article discusses experimental results to understand the mechanism behind bubble formation in glass-ceramics (GC). It is noted that GC were discovered by S. D. Stookey and it is defined as inorganic, non-metallic materials prepared by controlled crystallization of glasses via different processing methods. It is noted that a two-stage heat treatment was employed to determine the crystal nucleation kinetics at various temperatures.
