Glass Introduction

Introduction

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.

Raw materials:

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.

Float Glass process

The float process refers to the manufacturing process for flat glass. This process came into general use in the 1960s. Saint-Gobain installed its first factory equipped with float technology in Pisa, in 1965. The theory: as the molten glass ribbon comes out of the oven, it is floated on a bath of liquid tin. Result: the glass does not need polishing or smooth grinding. It is cut directly on the production line.
