The main ingredient in glass is SiO2 (sand)

Ceramics are heated to 1000C to drive out water and harden it.

The TWO types of glass are called:

Carbon fibres are mixed with plastic polymers to create lightweight composites

Ceramics have a disordered, giant structure with no crystalline regions

Borosilicate glass has a lower melting point than soda-lime glass

Ceramics have strong areas made up of covalent and ionic bonds

Glass has a disordered structure

Plywood is a composite material

The process of creating a composite involves a ................... and a ..................

Wet clay contains non-metals and metals in it's layers

Glass is heated to 5500C before being allowed to cool

Composite materials are made to combine and create new and improved useful properties

Recycled glass now makes up to 30% of most glass-making mixtures
