Glass  |  Tempering Lines 
 
 
Annealed glass which has been heated to a temperature near its softening point and forced to cool rapidly under strictly controlled conditions is called heat treated glass. The heat treating process produces highly desirable conditions of induced stress which result in additional strength, resistance to thermal stress, and impact resistance. Heat treated glasses are classified as either fully tempered (toughened) or heat strengthened according to mechanical properties achieved.
 
 
Heat Soak Test Furnace
 
Heat Soak Test Furnace is supplementary equipment for tempering lines. The test applied insures that if there is a probability of breakage then the infected panes break inside the furnace at the factory itself. Up to 95 % NiS (Nickel Sulphide) containing panes usually break inside the heat soak chamber at the factory premises and hence reduce the chances of breakages during use.
