Development of Nuclei and Growth of Zn2 Ti3 08 Crystal in a Zinc Porcelain Glaze (A Composite Material)

Abstract

The crystallization behaviour of a zinc raw glaze was investigated. In addition to the expected willemite crystals, a new crystal, Zn₂TiO₃0₈ was identified. This was a gold coloured angular crystal on a blue background of cobalt. It develops on cooling at about 1100°C. This is the first time this crystal is reported in a glaze. In an attempt to make experimental results clearer kinetic reaction, nucleation and crystallization theories and glazing procedures are reviewed in this paper.
