The first manufactured glass material dates back the 4th Millennium BC, in both Mesopotamia and Egypt. Heated crushed quartz was used to create glazes for ceramic vessels. We have come a very long way concerning glass since the 4th Millennium.
Modern laminated glass consists of a thin layer of polyvinyl butyral inserted between two layers of solid glass. This technology has been credited with creating the safety auto glass used in most automobiles.
While auto glass is quite sturdy, there may be instances or occurrences that happen that will require auto glasses repair or crack windshield repair. Hopefully, this does not come from “defenestrate”, meaning to throw something or someone out of a window.
