Why did Edouard Benedictus call his invention triplex?

In less than a day, Benedictus produced the very first sheet of laminated safety glass, which he called triplex because it was a film of cellulose nitrate sandwiched between two sheets of glass. The material was strong, but even if the panes broke, the pieces stayed put because of the plastic layer.

Where was Edouard Benedictus?

Edouard Benedictus, artist, designer, composer, and chemist was born in Paris, France on June 29, 1878.

How was shatterproof glass discovered?

Edouard Benedictus made an accidental discovery in his lab. One day, in 1903 he dropped a beaker sending the flask to the floor. It broke — but its pieces held together. Cellulose nitrate, a clear liquid plastic left in the beaker, had dried and kept the glass from breaking into shards.

When was tempered glass invented?

History. Francois Barthelemy Alfred Royer de la Bastie (1830–1901) of Paris, France is credited with first developing a method of tempering glass by quenching almost molten glass in a heated bath of oil or grease in 1874, the method patented in England on August 12, 1874, patent number 2783.

Which is better tempered or laminated glass?

While considering the strength to withstand breakage, tempered glass is considered to be stronger than laminated glass….

What is shatterproof glass made of?

What is Shatterproof Glass? Shatterproof glass is laminated glass; two or more sheets of glass bound together with an invisible interlayer of polyvinyl or resin, though other compounds are sometimes used.

What is Edouard Benedictus famous for?

Edouard Benedictus was a French chemist, inventor, painter, composer, book binder, textile designer, and all around clever clog. One day in 1903, he was pursuing one of his many projects when a momentous accident happened.

How was safety glass invented?

Safety glass was discovered accidentally by Edouard Benedictus, a French scientist in 1903 when he dropped a glass flask while he was working in his laboratory. This flask had contained cellulose nitrate, a liquid plastic, which enabled it to keep more or less its original shape when it had been dropped.

When did China discover glass?

Literary sources date the first manufacture of glass to the 5th century AD. However, the earliest archaeological evidence for glass manufacture in China comes from the Warring States period (475 BC to 221 BC). Chinese learned to manufacture glass comparatively later than the Mesopotamians, Egyptians and Indians.

Is tempered glass bullet proof?

Bulletproof glass, more commonly known by experts within the industry as bullet resistant or ballistic glass, isn’t truly bulletproof. Tempered glass, on the other hand, while able to stand up to damage, is vastly different from ballistic glass in the overall function it’s made for.

Why was Edouard Benedictus inventor of the month?

His accidental invention not only has saved millions of lives, but also laid the groundwork for future modernization of safety glass. For further Information. http://www.dyneema.com/americas/stories/2012/04/inventor-of-the-week-edouard-benedictus.aspx.

What did Edouard Benedictus use to make safety glass?

In safety glass …by an artist and chemist, Édouard Bénédictus, who used a sheet of celluloid bonded between two pieces of glass. Other plastics were also tried, but in 1936 polyvinyl butyral (PVB) was found to possess so many safety-desirable properties that its use became universal.

Why did Edouard Benedictus use cellulose nitrate in his flask?

Edouard was scratching his head wondering how this could be, when his assistant told him that the flask had cellulose nitrate (a liquid plastic) that had evaporated and left a thin film on the inside.

What kind of plastic was in the Benedictus flask?

On questioning an assistant, Benedictus learned that the flask had recently held a solution of cellulose nitrate, a liquid plastic, which had evaporated, apparently depositing a thin coating of plastic on the flask’s interior. Because the flask appeared cleaned, the assistant, in haste, had not washed it but returned it directly to the shelf.
