What kind of glass is used in your iPhone (or other smartphone) screen? |
The glass in most iPhone screens to date, along with that in many other smartphones, is trademarked with the name Gorilla® Glass. This is an alkali-aluminosilicate glass that has been used in over one billion devices! It is lightweight, thin, and resists scratching and cracking significantly better than many other types of everyday glass.

Pyrex® baking dishes are a common sight in many kitchens. The material is a soda-lime glass that is resistant to breaking and cracking.
