Aegina has long been recognised as a major production centre of a variety of widely exported ceramic containers not only in the relatively recent past but also in Classical antiquity and especially during the Middle and Late Bronze Age. Moreover, the prehistoric ceramic industry based on Aegina has become an increasingly important phenomenon in recent scholarship dealing with the rise of complex societies in the Aegean world during 2nd millennium BC. Such persistence on pottery production on Aegina through time renders obvious that a combination of factors, such as socio-economic, historical and geographical ones, as well as the locally available raw materials and the attraction of Aeginetan ceramics at other sites, must be taken into consideration in addressing the development of a specialized potting centre on the island. This study is the first to undertake a comprehensive look at the Aeginetan ceramic industry during much of the Bronze Age (ca. 2500-1200 BC), aiming at shedding light upon the factors influencing transformations in potting traditions, and the growth and decline of a specialised pottery production centre on Aegina. Advocating a landscape approach, it concentrates not only on pottery production but also on supply and consumption of ceramic vessels on the island. The systematic stylistic study of the formal attributes of local products and imports at the site of Kolonna is combined with the investigation of their manufacturing technology and the compositional characterisation of their fabrics through petrographic and chemical analysis. This integrated archaeological and scientific examination of the pottery, together with research on the island's resources, replication experiments and ethnoarchaeology, provides the ground for the reconstruction of the local potting traditions and the understanding variability observed within and across certain periods of the Bronze Age.

Different Types of Pottery Clay

!±8± Different Types of Pottery Clay

Pottery clay is the clay used to make the three categories of pottery: earthenware, stoneware, and porcelain. Clay is baked in a kiln under intense heat, a process known as firing, and becomes solid. Firing is used both to harden the clay and to adhere glaze to it or color it. In this article, I will give a brief introduction as to the different types of clay available for pottery.

Earthenware - This type of clay is very common, and generally contains a fair amount of iron and is made from porous pottery clay fired at low temperatures. Because it is fired at low heat, the pottery clay retains its porous nature. Faience, delft, and majolica are all types of earthenware clays. Stoneware - Stoneware is a clay that is generally a mixture of other clays. It has a high degree of plasticity which means it is very easy to manipulate, and is fired at a high temperature, and so becomes nonporous. You have probably eaten off of dinner plates made of stoneware. Porcelain-This pottery is actually made with a mixture of several other types of clay and minerals. It is generally composed of kaolin, ball clay, feldspar and flint. Porcelain, also called china, is fired using very high heat, resulting in a white, nonporous, translucent pottery. It does not have much plasticity and can be a challenge to work with. Ball clay- Ball clay is a rare mineral found in few places around the world. Its name dates back to the early methods of mining when specialized hand tools were used to extract the clay in rough cube shapes. As the corners were knocked through handling and storage, these cubes became rounded and 'ball' shaped. This clay has a finer grain than fire clay, and shrinks a great deal during the firing process. For this reason, it is usually mixed with kaolin, as kaolin clay has a low degree of shrinkage. Fire clay- There are two types of fire clay: flint clay and plastic fire clay. Because of its stability during firing, it can be used to make complex items such as pipes and sanitary ware. Fire clay can be easy to work with or not, as its degree of plasticity is variable. It usually has a very rough texture, and is often added to stoneware. Kaolin- Kaolinite is a clay mineral and is very pure, with a white color. It does not shrink much when fired, and must be fired at a very high temperature. As it does not have a high degree of "plasticity," it is usually used in conjunction with other clays.
So there you have it. six different types of clay that you inspiring potters can try. I recommend trying them all and see what works best for you. Everyone has a different opinion on which one is best. Use your own judgment when trying them to come to a conclusion.
