Laminated glass

Laminated glass consists of two or more layers of glass stuck together using a thin layer of PVB (plastic film). When broken the plastic film holds the broken glass together.

The French chemist Èduard Benedictus actually discovered the process behind laminated glass by accident. He dropped a beaker with a cellulose nitrate solution and found that it broke but did not splinter. The solution had made a thin film on the inside of the beaker that held the glass together. In 1909, he patented the first laminated glass.
