Transcript of Pottery

Pottery Physical Stages of Clay What is it? Potteryware can be made from many different materials such as, earthware, stoneware, and porcelain. Although, the main type of material many use is clay. When using these materials you can form them into many shapes. You can make objects starting from bowls to sculptures of people. How do you make it? To make pottery you must form objects and shapes then put them in a kiln to be heated at a high temperature. This removes the water from the clay which permanently forms the clay to the shape you made. This process of putting your pottery in the kiln is called firing. You can decorate pottery before or after firing. Clay There are many different types of clay. This is important to know when making pottery because certain clays hold more moisture which is absorbed when put in the kiln. You must be aware of the clay you use and how long to fire it so you do not wreck your potteryware. Kaolin- A clay found in China
Ball Clay- A very fine, grainy, plastic clay
Fire Clay- A high heat resistant clay that can be combined with other clays when making pottery
Stoneware Clay- This clay has many of the same characteristics as the others but has a very high heat resistance
Bentonite- Extremely plastic like clay that can be added in small amounts to other clays to make it a bit more solid Greenware: Clay before it's been fired. It is soft and can easily be reshaped.

Leather Hard: A clay object that has been partially dried with about 15% of moisture left.

Bone Dry: Clay that has no moisture at all.

Biscuit: Clay that has been shaped and fired to make a object or art piece.

Glost Firing: The final stage of glazing and decorating the pottery. History and Development The potters wheel was created in 3000 BC to make pottery completely round. People would put their shaped clay over bonfires to absorb the moisture. People made pottery before 3000 BC as well but with their hands strictly and no pottery wheel, making them use more skill and time.
Many people in the early days only used pottery for most of their everyday uses such as, bowls, plates, etc. This was because clay was something easy to get and to some degree it was fairly easy to make. In 500 BC the Greek were known for having the most advanced and best looking pottery. This is because Greek people discovered and began to experiment with different types of clay. Now a days people still make pottery but more for fun then an essential need. Most people now have plates and cups made from glass but we have other things still in this time made from clay. Some of these things include vases, some floor tiles, and random objects like garden gnomes. Hand made clay sculpture from
before 3000 BC. Grey clay bottle made in 1500 BC. Clay gardening pots made in 2012. Evolution of Pottery
