Corning Glass has a line of ceramic-hybrid glass with the registered name Gorilla Glass. Described as thinner, and lighter weight than other glass, Gorilla Glass is also reported to be harder than other glass and equal hardness to that of a sapphire. Gorilla Glass is subjected to a chemical process called ion exchange, which is what gives the glass the hardness for which it is known. According to the Corning website, the science behind Gorilla Glass was created in the 1960s but the product created then is compositionally different from the various incarnations of Gorilla Glass available today (there are four kinds of Gorilla Glass on the market). Gorilla Glass frequently can be found on electronic devices such as smart phones and tablets, and the company states that it can be used in automotive applications.
