Making Materials
CERAMICS
Ceramic means "of pottery" and it's made out of clay soil, that has been dug out of the ground and heated in a kiln.
-
-
-
-
Wear-resistant, non-magnetic, heat-resistant and are thermal and electrical insulators
-
COMPOSITES
-
Examples- laminated glass; glass is hard and rigid, polymer is plastic and flexible
Concrete, boats and kevlar
PLASTIC AND POLYMERS
HDPE- High Density
-
Less strong and lower melting point, softer and more flexible
-
BRITTLENESS
Inside the sturcture of ceramics, the structure is called silicon oxide, and when stress is put on the crystal, it breaks.
GLASS
First, silica sand mix is heated, then the glass is blown to shape it and mould it, then the stem is made by hand, and then the base is made by hand, then finally it is put in the kiln ant 840 Fareheit!

EXAMPLES: Ceramic tiles,mugs,plates,pots,vases,toilets and sinks
Polymer properties: flexible, light, strong, insulator, poor conductors of heat and waterproof
