Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension .

Prince Rupert's drops are produced by dropping molten glass drops into cold water. The glass rapidly cools and solidifies in the water from the outside inward. This thermal quenching may be described by means of a simplified model of a rapidly cooled sphere. [ 3 ]
For glass objects that are not window glass, the most common way of cleaning is by water if the glass object is intact and not super fragile. The Victoria and Albert Museum provides guidance about how to go about this way of cleaning. [4] The methods of cleaning may differ if the glass is already damaged, extremely thin or fragile, or very old.

A Nokia N8 with a Gorilla Glass screen. Gorilla Glass, developed and manufactured by Corning, is a brand of chemically strengthened glass now in its ninth generation.

The thin-glass bottles were probably made in England, Ard added, as the Spanish did not make their own glass. "Onion bottles are free blown using a pontil," Ard said. "Each one is unique, so there ...
Once a thermoset EVA is properly laminated, the glass can be presented frameless. There should be no water/moisture infiltration, very little discoloration, and no delamination due to the high level of bonding (crosslinking). [5] Newer developments have increased the thermoplastic family for the lamination of glass.
