GlasKing Tempered (Toughened) Product

Our GlasKing tempered or toughened glass is

uniformly heated in our Cooltemper Jetstream Flat
Glass Tempering Furnace. Once the glass has been
heated to the correct temperature, which is monitored
by the Cooltemper Glass Scan Thermal Imaging
System, it is rapidly quenched using high volumes of
cool air, delivered to both its’ top and bottom surfaces,
which then puts it into a state of compression.

This gives tempered glass its strength making it four to

five times stronger than ordinary annealed glass of the
same thickness.
As well as increasing the strength of the tempered
glass, the process also changes it into a safety glass and Glass Handling:
if it does get broken, the glass breaks into very small
harmless fragments. Spontaneous breakage can also occur if glass is not
handled correctly, such as by edge damage, surface

mostly Nickel Sulphide (NiS). Spontaneous breakage in
Heat Strengthened glass (see below) is virtually
unknown. Although the incidence of Nickel Sulphide
inclusion is low in good quality float glass, GlasKing
Tempered glass can be tested to destruction by a
process known as heat soaking.

This test is carried out at customer’s request.

Although not an absolute guarantee, the majority of
panes of glass with an inclusion will break during the
test. Our test is carried out in accordance with the
European standard EN 14179.
