  1. Tempered Soda-lime
    The glass is created by the heat treating process which result in additional strength, resistance to thermal stress, and impact resistance. When broken, it shatters into many small fragments.
       - Max. Temp. = 700deg.C
       - Normal Temp. = 180deg.C
       - Thickness= 5t ~ 19t
  2. Fused Quartz
    General Electric fused quartz products provide a wide range of useful properties.
       - Glasses for telescope and furnace, Optical glasses.
       - The design tensile strength = 7,000psi
       - The design compressive strength = 160,000psi
       - Working Temp. = 800~1025deg.C
