The base composite ingredient to the manufacture of any glass product is, of course sand. The other two critical ingredients being Sodium Carbonate and Calcium Carbonate. These ingredients alter the base molecular structure of the sand and lowers the melting point. This does not mean that a temperature of between 1,427 and 1,538 degrees Celsius can be seen as low! Not only does it take extreme temperatures to melt sand, it also takes an average period of three days.
During the melting process it is critical to minimize the amount of air pockets that can form. The first step is achieved by raking the sand mixture as it starts to melt. Then during a 10-
The next step in the process of achieving flat glass, without bubbles, has been in use since 1959 and was developed by Pilkington. The requirement? Creating a large, stable surface on which the glass can float in order to cool and solidify, flat and bubble free. The answer is ingots of melted tin.

Heat flows through a window in three ways: conduction, convection and radiation. When these basic mechanisms of heat transfer are applied to the performance of windows, they interact in complex ways.
Can be described as transfer between two surfaces in direct contact with each other.
Through movement between a solid surface and a gas heat is transferred through circulation.
Linked to heat emission, describing the capability of heat transfer of a surface. A lower emission will cause weaker heat transfer. Thus the higher the emission, the more heat will be radiated…Read More
