Mission Assignment Slide
Handout
Explain how the properties of materials are related to their uses and select appropriate materials.
Most of the glass we use is soda-lime glass, made by heating a mixture of sand, sodium carbonate, and limestone. Borosilicate glass, made from sand and boron trioxide, melts at higher temperatures than soda-lime glass.
Clay ceramics, including pottery and bricks, are made by shaping wet clay and then heating in a furnace.
Compare quantitatively the physical properties of glass and clay ceramics, polymers, composites and metals. Explain how the properties of materials are related to their uses and select appropriate materials.
