Dragontrail
Dragontrail, manufactured by Asahi Glass Co., is an alkali- aluminosilicate sheet glass engineered for a combination of thinness, lightness and damage-resistance, similar to Corning's 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.
