Most of the glass we use is soda-lime glass, made by heating a mixture of sand, sodium carbonate and limestone. |
|
How is soda-glass made? Making concrete - testing strength using masses (consider making lesson before or testing in subsequent lessons) |
|
|
|
Borosilicate glass, made from sand and boron trioxide, melts at higher temperatures than soda-lime glass. |
|
How is borosilicate glass made and what is the advantage of it over soda-glass? |

|
|
|
Students should be able to interpret and evaluate the composition and uses of alloys other
than those specified given appropriate information. |

Clay ceramics, including pottery and bricks, are made by shaping wet clay and then heating in a furnace. |
|
How are clay ceramics made? |
|
|
|
Most composites are made of two materials, a matrix or binder surrounding and binding together fibres or fragments of the other material, which is called the reinforcement. |
|
What is a composite and how are they made? |
|
|
|
Students should be able to recall some examples of composites. |
|
What are three examples of composites? |
