The more a glass is strengthened by internal stresses, the more stored energy, the more complete the shattering if the part does break. Corning formerly had a product line, referred to as Frangibles, that were strengthened to the point where they shattered into powder. The typical function of product within the frangibles product line was less as a cover glass and more as a disposable encapsulate. At one point, after the Tylenol poisonings, frangibles were considered for encapsulating medicines. The extreme level of strengthening necessitated a long time in the ion-exchange bath and most of the product line that I am aware of was for the military due, to the expense. Judging from what I have seen of broken mobile product with chemically strengthened coverglass, current practice is to strengthen the glass well below this level.Norman Hairstonhttps://www.blogger.com/profile/10483780552567247916noreply@blogger.com
