3.2 Specialist design principles

Primary sources of materials and the main processes involved in converting into workable forms for at least one material area.

• Paper and board (how cellulose fibres are derived from wood and grasses and converted into paper).

• Timber based materials (seasoning, conversion and creation of manufactured timbers).

• Metal based materials (extraction and refining).

• Polymers (refining crude oil, fractional distillation and cracking).

• Textile based materials (obtaining raw material from animal, chemical and vegetable sources, processing and spinning)
