Advantages and Disadvantages of Glass Tempering

Glass tempering is a high-end quality glass and is used in a variety of demanding applications these days. When a tempered glass is broken, it crumbles in small-sized granular chunks; this is because a balanced internal stress is created. The tempering of glass has been put into practice keeping in mind the environmental safety as an issue. An annealed glass is converted into a toughened glass through series of chemical and thermal treatments; thereby, it becomes less hazardous when broken into granular chunks; it is even less likely to cause any sort of injury.
One must keep in mind a few key quality areas, while choosing the best glass that is tempered:
Optical distortion - the lesser the distortion, the better would be the quality
Roller marking - it is produced if the glass is poorly handled in the furnace chamber
Waviness and Bending - it isn't a defect feasibly being a characteristic of heat-treated glass
Edge strength - the stronger the edges, the less-likely would be the thermal breakage
Fragmentation - it should be conducted for consumer safety and strength
Coating burns - a small area of the coating must be removed before cutting and scoring the coated glass
What are the different uses of glass tempering?
Tampered, also called toughened glass is known for its strength, thermal resistance and safety; therefore, this glass is most commonly used in making the side and rear windows in cars. It is also used in making windscreen, and building frameless doors, structurally loaded application and any other applications that may become fatal in an incident of human impact.
Rim of the glass or plates may also be tampered for their use in the food and hospitality industry. Manufacturers that make use glass tempering techniques include ePyrex, Corelle and Arc International. Toughened glass is also used in the microwaves and glass stoves.
What are the advantages of glass tempering?
The major benefits of glass tempering include:
Strength - it is four to five times stronger than an annealed glass
Safety - it disintegrates into relatively smaller pieces when broken by pressure reducing serious injuries and accidents
Edge strength - it is highly strong from the edges as tempering furnace compared to normal ordinary glasses
Thermal breakage - it is highly resistant to withstand any kind of thermal breakage
What are the disadvantages of a glass that is tempered?
Some of the disadvantages of glass tempering include:
Re-sizing, re-cutting and re-working on a toughened glass is not possible
The glass will break completely if its edges are damaged
The waviness on its surface creates problems in making thin film solar cells
