Spontaneous Breakage
Spontaneous Breakage

The formation of nickel sulphide (NIS) cannot be excluded in the mineral components used to form raw glass.  This compound is characterized by the growth of its crystalline structure during the natural process of glass ageing.  These continuously growing crytals are therefore capable of splitting the glass from inside.

The transformation porcess of these nickel sulphide inclusions following the tempering process of glass may break spontaneously even after an extensive period of time.
