THE CONTROL OF CRYSTALLINE GLAZES*

Abstract

A bstract In this investigation there is carried out the carefully controlled heat treatment of a single crystalline glaze in which both the crystallizing and growth velocity were determined for the four types of crystal produced. It was found possible to produce crystals at any desired location by seeding; their size could be controlled by the growing time and their shape by the growing temperature. Commercial production of crystalline glazes is possible if close temperature control is maintained.
