Both companies were chasing the same thing: the enormous market for flat glass. While Pilkington was working to develop flat glass, Corning Glass Works was developing a process of its own. Fusion draw produced a continuous sheet of exceptionally thin, pristine glass, but it was too slow to compete.
It was an idea that might have remained buried in scientific journals. Instead, it led to a device that gave modern telecommunications a much-needed boost. In the 1960s, Elias Snitzer, a physicist at American Optical, added rare earth elements to glass. These elements can absorb light energy—and,
In 1879, the brilliant inventor Thomas Edison was on the verge of a breakthrough. He had discovered a slow-burning filament that would glow for hours in the vacuum of a glass globe. But to create the first practical electric light, he needed a glass globe that would not implode when the air was
Why did such an important discovery occur so late in the … history of glass, and why was an accident necessary to bring it about? – Donald Stookey, 1977 Crystals are usually a glassmaker’s enemy. When they form in glass, crystals can change the properties of the material in unwanted ways.
Where the telescope ends, the microscope begins. – Victor Hugo, Les Misérables, 1862 A glass lens. It’s nothing more than a curved piece of glass. So simple. So familiar. It’s changed the way we perceive the world. In 1608, when Dutch spectacle maker Hans Lippershey held up two lenses, one
A little more than 2,000 years ago, a Roman glassworker did something that dramatically changed the course of history. He blew a puff of air through a hollow %%rod%% into a gob of hot glass. The gob inflated into a bubble. At that moment, glassblowing was born. Glassblowing provided a way to make
Edouard Benedictus, a set and costume designer for a French theater, wanted to make glass safer. He was disturbed by reports of people being disfigured by broken windshield glass during automobile accidents. How could windshields be made less dangerous? He recalled a curious incident that had
The world began to realize that so far it had only toyed with glass. Now a brand new material was born. -Walter Kioulehn, Odyssey of the 41 Glassmakers, 1959 By the mid-1800s, there were still only two kinds of optical glass: soda-lime crown glass and lead-containing flint glass. Opticians
I have heard a ray of the sun laugh and cough and sing! -Alexander Graham Bell It was a bright idea: use sunlight to transmit the human voice. In 1880, American innovator Alexander Graham Bell tried it, using a thin, flexible mirror to reflect a light beam onto a distant receiver. His voice
They make glass. By day and night, the fires burn on … and bid the sand let in the light. -Carl Sandburg, In Reckless Ecstasy, 1904. To see the unseeable: the quest is unending. But lenses and prisms are only as good as their glass. Optical-quality glass must be flawless. Even tiny flecks,
