…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
