Gorilla Glass Generation
Gorilla glass is a brand is specialized toughened glass developed and manufactured by Corning Inc. It is light, thin, scratch and cracks resistant. It is mainly used as a cover glass for smartphones, tablets, smart watches, television screens, etc." "During its manufacture, the glass is toughened by ion exchange. The material is immersed in a molten alkaline potassium salt at a temperature of approximately 400 °C (750 °F), wherein smaller sodium ions in the glass are replaced by larger potassium ions from the salt bath. The larger ions occupy more volume and thereby create a surface layer of high residual compressive stress at the surface, giving the glass surface increased strength, ability to contain flaws, and overall crack-resistance, making it resistant to damage from everyday use. "Gorilla glass versions : Gorilla glass 1 - • Introduced in 2007 with iPhone 3GS. • It had high scratch resistance than plastic screen covers of that time. • 1.5 mm to 2 mm in thickness...
