  11. This is a ‘tor’ on Dartmoor • Dartmoor is a National Park in Devon • The underlying rock is granite • Tors are found on hilltops and are the result of weathering of the granite

  12. This cup is made of porcelain • Fine porcelain is known as bone china • It was made in Stoke on Trent • Bone china is made from bone ash, china stone and china clay

  13. This harbour is Fowey (pronounced ‘Foy’) • It is in the south of Cornwall • It used to export china clay • Much of Cornwall’s china clay went by sea to Liverpool

  14. This is a close up of a piece of granite • Granite comprises three types of minerals: quartz is clear and greyish like glass mica is black and shiny feldspar is white (sometimes pink) • The feldspar can be weathered by a process called ‘kaolinisation’ • Many of the upland areas in Cornwall are underlain by granite

  15. This cone is in Cornwall • It is not a volcano! • It is made of quarry waste

  16. This is a pottery factory in Stoke on Trent • It has been preserved as a museum • The ‘chimneys’ are bottle ovens where porcelain was fired • Stoke on Trent was linked by canal and railway to the port of Liverpool

  17. This is a disused china clay pit in Cornwall • China clay was quarried using powerful jets of water to break up weathered (kaolinised) granite • The china clay (kaolin) then dried out as a powder

  18. This is the Eden Project near St Austell in Cornwall • It is located in a former china clay pit • Inside one of the ‘biomes’ there is a real living, growing rainforest

  19. These are granules of china clay or kaolin • When granite is weathered, the feldspar crystals within it break down into china clay or kaolin • China clay is an important ingredient for porcelain manufacture
