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
Lollipop heated to about 310˚F, the temperature that the solution is heated to is dependent on the specific volume and contents of the mixture. After heating is complete, the solution can then be cooled. The final cooled solution is a supersaturated due to the fact that the moisture content drops to below 2%. Supersaturated or supercooled liquids are also formed due to the fact that crystallization is being inhibited. They are unstable because crystallization is a favored reaction in this case. During the cooling process, the most important physicochemical characteristic of lollipops is occurring. This process is called glass transition. Glass
