El vidrio de seguridad laminado fue inventado por el químico Édouard Bénédictus después de un accidente de laboratorio en 1903. Un matraz de vidrio recubierto con el nitrato de celulosa de plástico se cayó, rompiéndose pero sin romperse en pedazos. En 1909 presentó una patente, después de enterarse de un accidente automovilístico que causó lesiones por escombros de vidrio.

Parabrisas de automóvil con grietas en "tela de araña" típicas del vidrio de seguridad laminado.

El vidrio laminado es un tipo de vidrio de seguridad que se mantiene unido cuando se rompe. En caso de romperse, se mantiene en su lugar mediante una capa intermedia, típicamente de butiral de polivinilo (PVB), acetato de etileno-vinilo (EVA) o poliuretano termoplástico (TPU), entre sus dos o más capas de vidrio. La capa intermedia mantiene las capas de vidrio unidas incluso cuando se rompen, y su alta resistencia evita que el vidrio se rompa en pedazos grandes y afilados. Esto produce un patrón de agrietamiento característico en "tela de araña" cuando el impacto no es suficiente para perforar completamente el vidrio. En el caso … Continuar leyendo (lectura de 7 minutos)

A glass flask coated with the plastic cellulose nitrate was dropped, shattering but not breaking into pieces. In 1909 he filed a patent, after hearing of a car accident causing injury by glass debris.”

    And the salesman said “hit it with a hammer to see if I’m lying”

    I work in the glazing & locks industry & I didn’t know that. Everyday is a school day

    I was told the glass jars of acid were laminated when I worked in a lab. I didn’t pay any attention. Then a lab worker really wanted to show me. A week or so later we finished off a bottle of acid and he made this big production of showing everyone. And he dropped the bottle into a large carboard box. It did what it was supposed to do and shattered inside its own laminated coating. Not as impressive as he made it out. But nice to see that they’re thinking of me.

    At least half of all inventions seem to be discovered by pure chance when messing up your actual experiment.

    I’m an engineer that works with laminated glass. This story is part of a lot of presentations I give to customers explaining the history of the product. Surprised to see it today on my front page!

    Any glass questions… AMA!

    I love the number of scientific breakthroughs come from accidents. There are no mistakes only happy accidents.

    Well I thankful to him …for my impact windows so much better than hurricane shutters.

    It seems chemistry is based on accidents.
