Do you know how glass was invented for cars?


July 5, Fineko/ In 1903, French chemist and physicist Edward Benedict, conducting his next experiments, accidentally dropped the flask (a container for experiments). Benedict was surprised that the flask did not break into pieces, but only cracked. Having examined the flask carefully, Benedict found out that the bottom of the flask was completely covered with a dry layer of nitrocellulose, which was used a few days ago for experiments and accidentally remained at the bottom of the flask. This case prompted him to think about creating an unbreakable, durable glass.

At that date, along with the rapid growth of automobile production, it was observed an increase of severe injuries (sometimes fatal) from broken fragments in car crashes. Benedict, who read in one of the daily newspapers about the death in another car accident, decides to make an unbreakable glass for car windows. He glued two layers of glass to each other with a layer of nitrocellulose. The resulting material became known as triplex.

However, despite the fact that this glass was intended for cars, in the first years after the patent had been received this glass was applied for other purposes. So, for the first time triplex was used for production of gas masks in the years of World War I.

Then in 1927, Henry Ford began to use unbreakable glass triplex in the production of his cars.

Subsequently, companies started using laminated glass in construction.
