…What’s glass?

Is an inorganic product of fusion which has been cooled to a rigid condition without crystallizing.

It is a hard material normally fragile and transparent common in our daily life.

Components…• Sand• Soda ash• Limestone

It is produced…By fusing these

materials at high temperatures, then cooling them quickly, forming a rigid structure, however not having enough time to form a crystalline regular structure.

… PropertiesSolid and hard material.

Disordered and amorphous structure.

Fragile and easily breakable into sharp pieces.

Transparent to visible light.

Inert and biologically inactive material.

Glass is 100% recyclable and one of the safest packaging materials due to its composition and properties.

• Commercial glass (soda-lime glass): appropiate to use in windows.

• Lead glass: appropiate for decorating purposes.

• Borosilicate glass: appropiate for kitchen or chemical labs purposes
