Interest in nickel sulphide inclusions in glass dates back to 1960s. In recent years, theoretical studies on the phase changes in nickel sulphide from a combination of thermal analysis, X-ray powder diffraction and Raman spectroscopy using reagent grade chemicals have provided significant insight into its transformation behaviour in laboratory conditions. Industry’s attention has focused on both the failure mechanisms of toughened glass panels containing nickel sulphide inclusion and the search for post processing remedial methods. This paper reviews both theoretical and practical aspects of dealing with nickel sulphide in toughened glass and proposes a two stage heat treatment model to ensure recrystallisation followed by growth of â-nickel sulphide grains from the precursor á-nickel sulphide polycrystalline inclusions.
