Jaymin Amin on ion exchange

“What we've chosen to do is to go really deep with our strengthening processes so that we create very deep compression layers on the surface of the glass — glass is weak in tension but it becomes really strong in compression, so flaws stay enveloped in that compressive region and don't penetrate all the way through.”

About Jaymin Amin
In a November 2020 conversation, Jaymin Amin, then Vice President of Technology and Product Development at Corning Gorilla Glass, discussed smartphone durability concerns. He stated that the primary consumer concerns are breakages from drops and scratches on cover glass, noting that people will live with scratches but not with breaks for extended periods. Amin explained that glass toughness is determined by its chemical composition and the strengthening process used, and that Corning creates deep compression layers on the glass surface to prevent flaws from penetrating. He also noted that glass thickness has decreased from about 1.2–1.3 millimeters in 2007 to 0.5–0.6 millimeters today. Amin discussed the introduction of Gorilla Glass Victus, which he described as the toughest Gorilla Glass produced to date. He said Victus has twice the scratch performance of previous generations and about four times that of competitive glasses, with drop performance of about two meters compared to around 1.6 meters for Gorilla Glass 6. Amin explained that the name Victus was chosen because the glass simultaneously improved both drop and scratch performance, a combination not achieved previously, and that the Latin word meaning "life" resonated with the company's culture of innovation.
