Over the past 36 years, research has mainly focused on the crystallisation kinetics and properties of glasses and glass-ceramics. A sampling of the most conclusive papers are reviewed here and include the following topics: the effects of liquid phase separation on crystal nucleation; tests and development of models of crystal nucleation, growth, and overall crystallisation; metastable phase formation; surface crystallisation; glass stability against devitrification; glass-forming ability; possible correlations between the molecular structure and the nucleation mechanism; sintering with concurrent surface crystallisation; and diffusional processes that control crystallisation. It was concluded that glass crystallisation remains an open, rich field to be explored.
