Architectural glass percent of the world's flat glass is produced by the float glass process invented in the 1950s by Sir Alastair Pilkington of Pilkington Glass, in which molten glass is poured onto one end of a molten tin bath. The glass floats on the tin, and levels out as it spreads along the bath, giving a smooth face to both sides. The glass cools and slowly solidifies as it travels over the molten tin and leaves the tin bath in a continuous ribbon. The glass is then annealed by cooling in an oven called a lehr. The finished product has near-perfect
Heated glass of supermarket freezers. In addition, display cases (such as in convenience stores and delis) use heated glass shelves to keep cooked food items from cooling. Heated glass Heated glass is a resistance heater created when a transparent, electrically conductive coating is applied to float glass and then subjected to an electric current. The electric current in the coating creates heat energy, which warms the glass until the glass radiates heat. The manufacturing process begins with the application of a microscopic Tin dioxide coating to a pane of float glass. This coating is transparent and conducts electricity. Then, two busbars are
