After the crystallization of calcium phosphate glass, a pattern of stripes like the rings of a tree is observed in the glass‐ceramic. The pattern of stripes, formed only from a particular glass composition and under specific crystallization conditions, is made up of voids resulting from a difference in density between the original glass and the resulting glass‐ceramic. The size and distribution pattern of these voids must be controlled to achieve maximum mechanical properties.
