SZG 6mm Heat Soak Tempered Glass Supplier and Manufacturer in China

6mm Heat Soak Glass also called 6mm HST glass. The aim of 6mm heat soak temepred glass is reducing the risk of spontaneous broken. 

What is NiS?

A nickel sulfide (NiS) inclusion is a rare imperfection that can occur if nickel-rich elements are present in the glass-manufacturing process. These elements, such as stainless steel, can combine with sulphur to form nickel sulfide inclusions.

What is heat soak test?

Heat soak testing is a destructive test. Tempered Glass is put into a heat Soak Oven and brought to and held at a temperature of 555 degrees Farenheit for two hours. Most glass containing Nickel Sulphide will shatter during this process and thus be eliminated from the glass project. 

Heat soaking is a process utilized to expose NiS inclusions in tempered glass before the glass reaches the field. It involves placing tempered glass inside a chamber and raising the temperature to approximately 290°C to accelerate nickel sulfide expansion. This is intended to cause glass containing nickel sulfide inclusions to break in the heat soak chamber, thus reducing the risk of potential breakage in the field.


1.Heat soak glass carry the risk of reducing the compressive stress in tempered glass.

2.Heat soak test reduce the risk of breakage due to inclusions

3.Heat Soak Testing protects against spontaneous breakage of toughened glass.

4.The Heat Soak Testing process adds longevity to toughened glass by eliminating foreign bodies that occur in raw materials of float glass especially “Nickel Sulphide (NiS)”.
