Leon Jacob, Ignatius Calderone

Nickel Sulphide induced spontaneous failure of toughened glass continues to occur in a few prestigious buildings. Unfortunately, there is no immediate solution to eliminating this problem. Heat soaking techniques are being formulated to minimize the risk of spontaneous fracture in toughened glass.

This paper focuses on the current position and the issues available to designers. As well as discussing the key issues, methods of predicting further breakage are presented, so that, based on the known success rates of heat soaking, confi dence can be gained in using the product when the risks are taken into account.
