Tempered Heat-Soaked Safety Glass
Although all tempered glass offers a high degree of resistance to breakage, all fully tempered glass are potentially at risk of spontaneous breakage due to the formation of nickel sulphide during glass production.
When nickel-rich contaminants such as stainless steel are present in the glass melt materials, the nickel may combine with sulphur in the batch to form an impurity called nickel sulphide. These impurities are minute in size ranging from 50 to 150 microns and cannot be totally eliminated by current technology. However, through a heat-soaking process, the risk of spontaneous breakage in tempered glass can be almost eradicated. In heat-soaking, the inversion of nickel sulphide stones to their low temperature phase is accelerated under a controlled process such that potential breakage of the glass happens in the factory rather than on-site.
SSG® DuraGlas-Q is a certified safety glass under AS/NZS 2208.

Low Risk of Spontaneous Breakage
Risk of spontaneous breakage due to nickel sulphide formation is almost eliminated in SSG® DuraGlas-Q.
SSG® DuraGlas-Q is four to five times mechanically stronger than annealed glass of the same type and thickness. The compressive surface stresses close microscopic cracks and strengthens the glass.
In occasions of breakage, SSG® DuraGlas-Q breaks into small and granular harmless pieces, unlike the sharp and jagged shards from broken annealed glass. This makes SSG® DuraGlas-Q less injurious than ordinary annealed glass and a classified safety glass.
SSG® DuraGlas-Q can withstand temperatures up to 295˚C. It can also endure temperature shocks of 150˚C without breakage, making it approximately three times as resistant to rapid temperature changes as annealed glass.
