Ceramic products have accompanied people from the earliest times. Clay firing technology has been known for nearly all over the world, however, the shapes and colors of objects created in this way vary considerably from place to place. Traditionally, ceramic dishes and ornaments were stained with glazes, the color of which depended on the raw materials available in the region. In addition, painted patterns referred to local aesthetic tastes, which differed even in the neighboring provinces. Traditional art experts are able to determine the region and time of production on the basis of shape and ornamentation.
