How is bulletproof glass made?
Bulletproof glass is composed of two sheets of plate glass with a sheet of transparent resin (adhesive) in between, molded together under heat and pressure. When subjected to a severe blow, it will crack without shattering. Today’s bulletproof glass contains multiple glass and plastic layers molded together. Sources: Brady, George S.
