12mm Clear/Low Iron Toughened Glass Panel

It is processed by heating 12mm clear float glass, 12mm low iron glass, 12mm tinted glass, or 12mm frosted glass to 650 degrees softening point, and then quenched rapidly. It creates tension inside the glass and compression outside the glass surface.

 

Heating Time

12mm clear/low iron tempered glass in Radiant furnace: 39s/mm, total 465 seconds~475 seconds

12mm clear/low iron toughened glass in Forced Convection furnace: 28s/mm, 275 seconds~285 seconds

12mm tinted/colored tempered glass in Radiant furnace: 35s/mm, 422 seconds~432 seconds

12mm tinted/colored toughened glass in Forced Convection furnace: 28s/mm, 330 seconds~340 seconds

 

Quenching Time

12mm toughened glass Quench Time=Glass Thickness^1.8=12mm^1.8=88s

 

Compression & Tension Zone

21% (2.52mm) up & down part with compression, 58% (6.96mm) middle part with tension.

Surface compression >90Mpa (over 13000Psi).
