With the discovery of techniques for controlling the nucleation and crystallization of many glass compositions came the need for improved methods for determining the percent crystallinity of a variety of glass‐ceramic materials where the crystal size was generally too small for analysis with the polarizing microscope. The development of areal analysis, lineal analysis, and point‐counting methods is reviewed. The application of the point‐counting method employing electron microscopy and diffraction to glass‐ceramic materials is discussed and demonstrated.
