What Is the Right Way to Fix Cracked Glass?

Proper repair techniques for fixing cracked glass depend on the context and the severity of the crack; for example, a crack in a car's windshield can be treated with a filling product or the windshield can be replaced entirely while a cracked wine glass might be fixed with clear epoxy glue or may need to be discarded. Glass that will be used in the preparation or consumption of food or drink will need to be treated with a food-safe adhesive or sealant, and if this is not possible, it may be necessary to discard or repurpose the glass. In some cases, cracks in glass can spread even if repair steps are taken.
