Classification of Materials
Materials used in the design and manufacture of products Plastics Wood Ceramics Metals Fabrics
Classification of Materials (Fabrics) Fabrics can be further classified as natural and synthetic NaturalSynthetic CottonNylon CanvasPolyester
Metallic Lustre (appearance) Metallic minerals have the lustre of polished metal surfaces will act like a mirror. Examples include Gold and Silver.
Dull Lustre (appearance) Dull minerals exhibit little to no lustre, due to coarse granulations which scatter light in all directions.
In general, materials can be classified as “soft” and “hard” materials. For example a pillow is soft and a wood is hard. Soft and hard materials
Properties of Minerals Geologists use characteristics to tell one mineral from another.
