Question

Name the process used to convert brittle glass into toughened glass.

Answer 1

TESTING THE GLASS involves punching it to make certain that the glass breaks into a lot of small, similarly sized pieces. One can ascertain whether the glass has been properly tempered based on the pattern in the glass breaks.

Tempered glass is about four times stronger than "ordinary," or annealed, glass. And unlike annealed glass, which can shatter into jagged shards when broken, tempered glass fractures into small, relatively harmless pieces. As a result, tempered glass is used in those environments where human safety is an issue. Applications include side and rear windows in vehicles, entrance doors, shower and tub enclosures, racquetball courts, patio furniture, microwave ovens and skylights.
