(Above) Manufacturing laminated glass windshields.
(Below) A crack in laminated glass. The crack comes from a stone hitting the windshield. Notice that the crack is only on the outer layer and that the whole windshield has not shattered. This is an important safety factor for drivers.
(Right) During the
manufacture of a three-

(Right and below) A laminated glass seen from the side, showing the sandwich of layers.
