Pottery is the craft of making ceramic materials or pottery wares using clay, creativity, and taste of the artist. Undoubtedly, pottery is the oldest craft of all times that has been invented and utilized to meet the material and metaphysicalneeds of life of human being in nature. Early potteries date back to 8000 BC which were made without using a pottery wheel and kiln. They were heated by the open fire of a cooking furnace and were generally used to keep and store food and other nutritious materials. The first pottery wheel and kiln were found in Kashan Silk Hill which reveals the significance of pottery in old Iran and emphasizes their great share of practice in making different types of earthenware in the old ages. Inventing pottery wheel in 3500 BC was a great achievement in pottery which has made a great change. Pottery is often made of clay and moldedby hand; yet black and white clay are sometimes used. The molding method was very common in making various types of round pots before the development of pottery wheel. Yet it is still used for unsymmetrical or very large types of pottery which cannot be made by the pottery wheel. It is possible to make any object of rotational symmetry on the pottery wheel. The crafted objects usually lose moisture as they are detached from the wheel. Leather-hard is the condition of the clay body when it has partially dried to the point where all shrinkage has completed and it has a consistency similar to leather. At this stage details such as handles and spouts are often attached to the main body, and many forms of decoration, including painting, may be applied by needles or other instruments. The decorations are carving, latticework, engraving, and relief which furnish the flat surface into an artistic decoration. When dried up, the pots are heated up to 950 degrees of centigrade in kiln and the product iscalled biscuit. These bodies are painted, glazed, and returned to the kiln for the second heating up to 1000 degrees of centigrade to make the glaze stuck to the main body. Paintings are either done under the glaze layer or over it. Flower, nightingale, and fish paintings are common in products of Isfahan;they are called seven colored painting. The under glaze painting in cyan colored pottery of Shahreza is commonly known in the world primarily for its black drawings. A distinguished product of Isfahan is the white clay pottery that is rarely produced due to its difficult stages of production. The white clay pots which are known as stone pots are made in Natanz city and decorated with under glaze paintings as well as relief glazed layer. Pottery evaluative factors are delicacy of paintings, unscratched glaze layer, lightness, and lack of raw lime pieces in the body.
