Gorilla glass is manufactured by Corning. It has high strength and doesn't get scratched. Even if you drop your smartphone having gorilla glass it won't break.
Reason for high strength and scratch resistance:
During the manufacturing of gorilla glass large ions are stuffed into the glass surface by a process called as ion exchange process. During ion exchange process large potassium ios replace th small sodium ions thus making the glass all the more harder stronger and scratch proof.
