Dragontrail

Dragontrail is an alkali-aluminosilicate sheet glass manufactured by AGC Inc. It is engineered for a combination of thinness, lightness and damage-resistance, similarly to Corning's proprietary Gorilla Glass. The material's primary properties are its strength, allowing thin glass without fragility; its high scratch resistance; and its hardness  with a Vickers hardness test rating of 595 to 673.
