The manufacturing of transparent float glass begins with the melting of raw materials in a furnace at temperatures reaching 1,700 degrees Celsius (about 3,092 degrees Fahrenheit). Once the mix reaches a molten state, it is poured onto the tin bath, where it spreads out evenly. As it cools, it solidifies into flat sheets. The thickness of the glass is controlled by adjusting the flow rate of the molten glass and the speed at which it is drawn off the tin. The resulting product is then annealed in a lehr, which helps to relieve internal stresses, ultimately enhancing its durability.

In an article in the Atlantic, glass was called humanity's most important material. In order to connect you and me, writes Douglas Main, these words are encoded into optical signals that travel at 300, 000 kilometers per second through fiber-optic cables, across mountains, underwater, across cities and countries, and across the globe. The glass inside these cables is thinner than a human hair and 30 times more transparent than the purest water. Glass allows us to see and be seen, to hear and be heard, to light up our rooms, our lives and our thoughts.
