Tempered glass is the glass subjected to a special thermal processing, which makes it stronger and more resistant to temperature fluctuations.
Producing tempered glass begins with the feeding by conveyor of cut-to-size annealed sheets of glass ( with minimum arise edges ) into furnace. The glass oscillates back and forth on ceramic rollers to an approximate temperature of 690˚C under computer control, the glass moves into the quench where it is rapidly cooled by high pressure cool air. This ‘ Snap ‘ cooling or quenching induces compressive stresses to the glass surface, while the center remains in tension. Although the physical characteristics remain unchanged Fully tempered glass is approximately four times stronger than annealed glass of the same thickness and configuration, and residual surface compression must be over 10,000 psI for 6mm,according to asTm C 1048. When broken, it will break into many relatively small fragments, which are less likely to cause serious injury. The typical process to produce tempered glass involves heating the glass to over 1,000 degrees F Or 700 C, then rapidly cooling to lock the glass surfaces in a state of compression and the core in a state of tension as shown in the diagram. Tempered glass is often referred to as “safety glass” because it meets the requirements of the various code organizations that set standards for safety glass.

Tempered glass possesses a set of qualities that makes it belong to safety glass type:

  • high mechanical strength
  • high temperature resistance, resistance to temperature fluctuations
  • safety in case of shatter

Tempered glass can be used as a part of insulating glass units, laminated glass and in single glazing.

Advantages and Features of using Pharos Tempered Glass:

  • Safety:

After broken, the toughened glasses will be broken into small fragments as small as

Bean. Thus, the possibility of its harm to body can be reduced.

  • High Strength:

Ended glasses are generally 4-­5 times as strong as the common annealed glasses.

  • Hardness:

4~5 times of that of the common Annealed glass.

  • Thermal Stability:

With good thermal stability, to be able to withstand the temperature

Of the glass is three times as big as the common ones.
