Glass windows are great, but they waste energy. A glass pane provides only slightly more insulation than nothing at all. Even so, builders were using more, and bigger, windows. Then, in 1973, the energy crisis hit. Harvard University chemist Roy Gordon knew that a tin oxide coating would make
When you think of a window, you think of a flat piece of glass. But window glass didn’t always start out flat. It once began as a massive bubble on the end of a glassblower’s pipe. To flatten the bubble, the glassblower could spin it rapidly into a huge disk called a crown. After it was cool, the
The auto and building industries boomed after World War II. Plate glass was in extremely short supply. Twin-grinding—used all over the world to make the glass—was too costly and too slow to keep up with the demand. Could high-quality glass be made without grinding and polishing? Alastair Pilkington
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.
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
Glass manufacturers had spent centuries learning how to make flat glass. Now, they wanted to bend it into complex shapes—without marring its surface. Anything that touched the surface of the hot glass could leave a mark. The first curved windows were made by slumping. A glass sheet was placed in a
Glass breaks. But if it’s strengthened by thermal tempering, it breaks less easily and more safely. By 1920, architects and European car designers wanted more and more tempered glass—and in large sheets. Glassmakers could successfully temper only one sheet in ten. There’s a trick to tempering: heat
The mighty glowing columns that stand like pillars in a ghostly cathedral... -Anonymous At the beginning of the 20th century, there was no way to mass-produce flat glass. Although glass cylinders could be drawn by machine, they had to be opened and flattened by hand. What was needed was a way
The space shuttle has triple paned, optical-quality windows. Thirty-seven window panes in eleven different sizes and shapes are produced for each Orbiter. The %%fused%% %%silica%% outer panes of the forward windshields are designed to withstand high atmosphere reentry temperatures. The inner,
