Type definitions also incorporate additional information about dates, origins, costs and functions of pottery. This page is intended to illustrate the basic principals of visual ceramic type identification, which will allow users to access additional information. Most types of historic ceramics that is, post ceramics of European origin or inspiration are classified according to three primary attributes:.

The first step in identifying a pottery type should be the identification of paste type. You can click on the glossary links to see examples of paste types and colors. The next step involves the surface treatment. Once the paste type is identified, it is necessary to identify the general category of surface treatment. You can click on the links to see examples.

A Brief History of Ceramics and Glass

There are three basic categories of pottery: earthenware, stoneware and porcelain. They vary according to the clay used to make them, and the temperature needed to fire them. This is the longest-established type of pottery, dating back to the Stone Age. Although its composition can vary significantly, a generic composition of earthenware clay is: 25 percent ball clay, 28 percent kaolin, 32 percent quartz, and 15 percent feldspar.

It is the softest type, being fired at the lowest temperature.

Pottery identification is a valuable aid to dating of archaeological sites. Clay – mostly derived from sedimentary deposits brought by rivers, glaciers, wind etc.

Carbon dating of pottery and ceramic. Whether is it possible? Pottery and especially pottery sherds most often present at archaeological sites worldwide. They are preserved for long because of physical parameters of their matrix. In some cases they are used for dating sites ‘relatively’ taking into account their different peculiarities: form, picture and ornament, kind of matrix, kind of inclusion and additives etc.

Unfortunately such dating could not be applied for any sample and site.

MOST clays contain a few parts per million of uranium and thorium and a few per cent of potassium, so that the body of an ancient pot receives a radiation dose of the order of 1 r.

Some of this energy is stored in the constituent minerals of the clay either by the creation of new lattice defects or by the filling of existing impurity traps. On heating, some of this energy is emitted as visible light. The present communication reports the results obtained on potsherds ranging back to 8, years in age and widely spread in provenance.

Dating – Hall China Marks

A team at the University of Bristol has developed a new method of dating pottery which is allowing archaeologists to date prehistoric finds from across the world with remarkable accuracy. The exciting new method, reported in detail today in the journal Nature , is now being used to date pottery from a range of key sites up to 8, years old in Britain, Europe and Africa. Archaeological pottery has been used to date archaeological sites for more than a century, and from the Roman period onwards can offer quite precise dating.

But further back in time, for example at the prehistoric sites of the earliest Neolithic farmers, accurate dating becomes more difficult because the kinds of pottery are often less distinctive and there are no coins or historical records to give context. This is where radiocarbon dating, also known as 14C-dating, comes to the rescue.

Chinese ceramics vary greatly in their glazes and decoration, and the many technical terms involved can be daunting for collectors who are new to the category. So what is a glaze? The most important ingredient in the glaze is silica, and the variations in type depend on the addition of other materials. Glazes can be applied to the ceramic bodies either before or after firing — techniques known respectively as underglaze and overglaze decoration.

Glazes were originally used for practical reasons because many stoneware and earthenware pots were too porous to act as containers, but aesthetics also played a part. The first Chinese ceramics — handbuilt earthenware pots — date back tens of thousands of years to the Palaeolithic period, but it was not until the Sui and Tang dynasties — AD that technology developed sufficiently for craftsmen to be able to produce uniform vessels on the wheel and colourful glazes in the kiln.

A very rare and important sancai -glazed pottery figure of a female polo player, Tang dynasty AD During the Tang dynasty — AD , Sancai wares were widely used for burial goods such as vessels and figurines. So they left the features unglazed, and later painted them in with coloured pigments. With many of the pieces we see today, the pigment is lost because it’s mostly composed of organic materials, but the glaze remains vibrant.

The Song dynasty, in contrast to its predecessor, the Tang, is known for monochrome, very cool-toned glazes which resemble jade and silver, snow and ice. Song dynasty monochrome glazes have a very modern feel to them, even though they’re more than 1, years old. I never fail to be amazed at how they can achieve that very harmonious balance between the shape and the glaze,’ comments Chang.

This glaze is particularly special because it contains agate, which was extremely difficult to source at the time.

The following is a basic introduction to pottery in archaeology, focusing particularly on the ceramics of the medieval period. The bibliography at the end provides references to more detailed and comprehensive sources. Small fragments of pottery, known as sherds or potsherds, are collected on most archaeological sites. Occasionally whole vessels are found, particularly where they have been used as grave goods or cremation ‘urns’.

Since prehistoric times, engineered ceramic and glass materials have had significant roles in most technologies. Ceramics is one of the most ancient industries going back thousands of years. Once humans discovered that clay could be found in abundance and formed into objects by first mixing with water and then firing, a key industry was born. In this location, hundreds of clay figurines representing Ice Age animals were also uncovered near the remains of a horseshoe-shaped kiln.

The first examples of pottery appeared in Eastern Asia several thousand years later. It is believed that from China the use of pottery successively spread to Japan and the Russian Far East region where archeologists have found shards of ceramic artifacts dating to 14, BCE. Use of ceramics increased dramatically during the Neolithic period, with the establishment of settled communities dedicated to agriculture and farming.

However, earthenware can be made impervious to liquids by coating it with a ceramic glaze , which the great majority of modern domestic earthenware has. The main other important types of pottery are porcelain , bone china , and stoneware , all fired at high enough temperatures to vitrify. Earthenware comprises “most building bricks, nearly all European pottery up to the seventeenth century, most of the wares of Egypt, Persia and the near East; Greek, Roman and Mediterranean, and some of the Chinese; and the fine earthenware which forms the greater part of our tableware today” “today” being Outside East Asia , porcelain was manufactured only from the 18th century AD, and then initially as an expensive luxury.

After it is fired, earthenware is opaque and non-vitreous, [7] soft and capable of being scratched with a knife. Generally, earthenware bodies exhibit higher plasticity than most whiteware [8] bodies and hence are easier to shape by RAM press , roller-head or potter’s wheel than bone china or porcelain. Darker-colored terracotta earthenware, typically orange or red due to a comparatively high content of iron oxide , are widely used for flower pots, tiles and some decorative and oven ware.

Some studio potters follow the reverse practice, with a low-temperature biscuit firing and a high-temperature glost firing. The firing schedule will be determined by the raw materials used and the desired characteristics of the finished ware. Historically, such high temperatures were unattainable in most cultures and periods until modern times, though Chinese ceramics were far ahead of other cultures in this respect.
