From hot to cold – Annealing process. Annealing describes the process in which the glass containers are cooled down after the moulding process. This is achieved in a heated furnace called "Lehr", where the glass is slowly cooled down to avoid breakage or damages. The temperatures of this cooling area are between 590 °C and 450 °C.

Secondly, the different types of raw materials required for glass making in ancient times and in more modern periods are discussed: these include vitrifiers, flux materials, stabilizers, fining agents, opacifiers and colouring agents. In some cases also reducing agents were employed. The use of specific recipes and mixtures of the afore ...
The main raw material used to make glass is sand. To make clear glass, a special sand called silica sand is used. This fine white sand is needed because it is very pure and does not contain other unwanted chemicals. It is "washed" to remove as many impurities as possible, as impurities can adversely affect the clarity and color of the glass.
Raw materials. The float glass process begins with a mixture of raw materials including key ingredients of silica sand, soda ash, limestone and dolomite.
There are a number of different ways to make glass, depending on the desired finished product. No matter what type of glass is being made, the process begins with slowly heating all of the raw materials in a furnace to approximately 2,550 degrees Fahrenheit until they melt.
