        excellent thermal insulator
        
        various natural colours, but easily dyed
        
        Resistant to acids
        
        from sheep
      - Silk
        
        Made from a material secreted by a worm called a silkworm, which forms extremely fine threads
        
        Highly resistant and elastic
        
        Good thermal and electrical insulator
    - - Asbestos
        
        fireproof
        
        used for fire-resistant roof
        
        fibrous mineral
        
        A health risk to use and inhale
      - Metals
        
        threads of gold, silver and copper
        
        used to make cloth
- - - - Then mixed with water to make a paste that hardens rapidly
      - Water-soluble adhesive when first mixed that is resistant to pressure and to fire
      - Processed from crushed gypsum that is dehydrated
      - Used to make archways, partitions, and as a covering for walls and paving
    - - Grey powder made from a mixture of crushed and heated limestone, clay and gypsum
      - Mixed with water to make a soft past
      - Very strong and resistant
      - Used to make mortar and other binders for construction materials like bricks
    - - Mixture of gravel, sand, water and cement that dries and hardens
      - Strong resistance to pressure
      - Adheres to steel, used to make reinforced concrete
      - Used to make foundations for buildings, bndges...
    - - Binder made from cement and sand, hardens when mixed with water
      - Used to hold together construction materials like bnck, cement block and paving stone, and to make artificial stone
  - - - Drying: To allow all water to evaporate
      - 5.. Baking in an industrial oven called a kiln at temperatures between 700'C and I 700'C.
      - Modelling: We shape the clay in the form of the object we want to make
      - Glazing and enamelling.
      - Mixing: We add water, anti-grease agents, fluxes and colouring.
      - Preparig the clay: We clean the clay to remove traces of vegetable matter, then apply a breakdown process using rollers.
    - - There are two large groups: structural ceramics and whiteware ceramics
    - - Clay is a fine-grained earth composed of aluminium silicates It's soft, porous, resistant to high temperatures and chemically inert.
        It has many different. colours; it's abundant in nature and very versatile.
  - - - Brilliant sheen when polished
      - Used on floors and walls, in architecture and in sculpture
      - Widely varied natural colours
      - High density, cold to the touch, hard, high resistance to environmental conditions
    - - Extracted from the Earth in smooth flat pieces that are cut and pressed
      - Used mainly to cover roofs and as paving stones
      - Hard, dense and compact, making it waterproof
  - - - Mould blowing
        
        When the mould is completely cooled, iyig
        we remove the obiect.
        
        We put the paste into a hollow mould which has the shape of the object we want to make
        
        We close the mould and inject compressed air, causing the paste to adhere to the sides of the mould
      - Float glass making
        
        We float molten glass on top of a layer of molten tin. The glass spreads to form a sheet that we pass through a system of rollers. We leave it to cool
      - Lamination
        
        We pass the soft material through a system of rollers The rollers can be smooth, or engraved to create a design on the glass
