Does Clay shrink when fired?

Clay shrinks both in drying and in firing. Different clay bodies shrink at different rates which can be as little as 4%, or as much as 15% for some clay bodies. We also found through out after years of firing that even with the same clay body, shrinkage can vary 1-2% from batch to batch.

Where clay is found?

Most clay minerals form where rocks are in contact with water, air, or steam. Examples of these situations include weathering boulders on a hillside, sediments on sea or lake bottoms, deeply buried sediments containing pore water, and rocks in contact with water heated by magma (molten rock).

What rock does clay come from?

Clay is a soft, loose, earthy material containing particles with a grain size of less than 4 micrometres (μm). It forms as a result of the weathering and erosion of rocks containing the mineral group feldspar (known as the ‘mother of clay’) over vast spans of time.

Who used clay pots?

The Egyptians made kilns to place their clay pots in for firing. The kiln was lined with a kind of insulation brick that was made from a mixture of straw and clay which had been dried in the sun. Later, the ancient Egyptians used a finer clay with a high quartz content for their delicate pottery.

What happens when clay is fired?

Organic matter in the clay is burned and oxidized to carbon dioxide, and fluorine and sulphur dioxide from materials in the clay body are driven off at 1292–1652°F (700–900°C). At this point the biscuit firing is completed. The clay particles are sintered or welded together. The fired clay is known as metakaolin.

Does clay need to be fired?
