Duratuff is a method developed by Libbey to strengthen their glassware, making it one of the best for the hospitality sector to use. By re-heating the glasses rim to almost melting point makes the rim stronger, but also stable. The method reduce breakage and chipping of the rim, but also to change how a glass breaks. It doesn’t break in an explosive manner and therefore much safer to use in food service location.
