Glass is the name given to all amorphous bodies that are obtained by lowering the temperature of a melt independently of its chemical composition and the temperature range of solidification, which as a result of the gradual increase of viscosity adopts the mechanical properties of a solid body.
Glass is melted at a temperature between 1000 and 2000° C.
The microscopic structure of glass is comparable to that of a liquid in which the individual constituents form an irregular network without a long range order. Glass is also the name given to a cooled melt.
The substances are introduced in the form of quartz sand, soda and lime. 5% oxides such as magnesium and aluminium oxide are added to this mixture. These additives improve the physical and chemical properties of the glass.
