Pottery is the process and the products of forming vessels and other objects with clay and other ceramic materials, which are fired at high temperatures to give them a hard, durable form. Major types include earthenware , stoneware and porcelain. The place where such wares are made by a potter is also called a pottery plural “potteries”. The definition of pottery used by the American Society for Testing and Materials ASTM , is “all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products. Clay as a part of the materials used is required by some definitions of pottery, but this is dubious. Much pottery is purely utilitarian, but much can also be regarded as ceramic art. A clay body can be decorated before or after firing. Clay-based pottery can be divided into three main groups: earthenware , stoneware and porcelain. These require increasingly more specific clay material, and increasingly higher firing temperatures.

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.

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.
Until now, archaeologists had to radiocarbon date bones or other organic materials buried with the pots to understand their age. But the best and most accurate way to date pots would be to date them directly, which the University of Bristol team has now introduced by dating the fatty acids left behind from food preparation. He said: “Being able to directly date archaeological pots is one of the “Holy Grails” of archaeology. This new method is based on an idea I had going back more than 20 years and it is now allowing the community to better understand key archaeological sites across the world.
There’s a particular beauty in the way these new technologies came together to make this important work possible and now archaeological questions that are currently very difficult to resolve could be answered.
Thames foreshore fragments and visual references
By the gradual curve of the rim sherd and the enameling on both sides, I would guess that it was once part of a large vessel meant to hold water or other liquids. My best, although very inexperienced, guesses for usage would be that it was either once a part of a water pitcher, or, if the West Room did, in fact, serve as a smith, at some point, that it was used to hold water for cooling hot iron. Perhaps the vessel they belonged to was passed down through generations and, eventually, found its final resting place in the West Room?
Rim sherds are very useful for determining the shape and size of the vessel and a good deal about the pot can be learn with a few sherds, which gives us hope for our artifacts, because we found at least five rim sherds. The current consensus seems to be that the West Room was likely constructed in the early to mid s, so, it possible, some of the pottery vessels were in use elsewhere, first.

When an archaeologist says that a site was inhabited, say, during the late s A. There are many methods used to date archaeological sites. Some, like radiocarbon dating of materials like burned wood or corn, measure the age of a sample directly and provide calendar dates. Unfortunately, not every site produces materials that can be dated in this way. In addition, radiocarbon dating often gives a date range with quite a large standard error, which may not be all that useful for certain time periods.
Dendrochronology , or tree-ring dating, is one of the best tools available to Southwestern archaeologists, but it requires wood from certain tree species, such as oak or Ponderosa pine. If the residents of a particular village used different species for construction, or if wood beams were not preserved at a particular site, dendrochronology is probably not an option for site dating.
This has been a problem in our research in the Mule Creek area; although we hold out hope for materials recovered during our excavations, none of the many samples that we have submitted for tree-ring dating have been datable thus far. This is where pottery comes in, particularly decorated pottery—which, luckily, is common on many Southwestern sites after about A. We know that many decorated pottery types were made and used during particular time periods in certain areas because they have been cross-dated; that is, archaeologists have found them regularly in excavated contexts that have been tree-ring dated.
Some parts of the southwest, such as the Cibola region on the Colorado Plateau, have very precise ceramic chronologies. As such, archaeologists feel confident that they know the production dates give or take 25 years for various pottery types made in the Cibola region, and they can assign dates to sites based on their relative frequencies of decorated ceramic types.

For thousands of years, people throughout the world have been using clay to make pottery containers of various forms for use in their daily lives. Pottery vessels are essential for storing, cooking, and serving food, but once they break and lose their usefulness, they are discarded along with other household refuse. Pottery, unlike other materials—such as paper or metal—does not decay in the ground.
It lasts for hundreds or even thousands of years for archaeologists to excavate and study. From a single sherd, a piece of a broken vessel, we try to determine what an object would have looked like and how it was used. This information, along with other discoveries, helps us understand how people lived in the past. There are three main types of clay: earthenware, stoneware, and porcelain.
All types must be fired, either in an open fire or in a kiln, to remove moisture and transform the clay into a ceramic object. Earthenware is fired at the lowest temperatures, porcelain at the highest—which gives porcelain the hardest body. Earthenware is porous unless it is glazed, whereas stoneware and porcelain vessels are generally watertight without glaze, although they are usually glazed to give them an attractive glossy surface.
Radiocarbon Dating Pottery
The most frequently found artefact on the archaeological excavation site is the potsherd. Sherds are broken remnant pieces of items such as bowls, jugs, drinking vessels and most commonly, pots. Most sites are literally smothered with potsherds, some large the size of a hand and some small only as big as a fingernail. It is relatively rare to find whole, undamaged pieces.

Safety Rules Other Forms of Research. China shards are the most helpful in figuring out the time of the former settlement’s disappearance – either before the 19th or 20th century. It is very easy to determine if the shards belong to the plateware manufactured before the 19th century. The old porcelain pieces show crackled glaze, spots without glaze, and brown-colored edges. The darker the color of edges, the older the shards. The 19th century porcelain shards can be distinguished from the older shards by the absence of crazing on glaze and availability of the manufacturer’s coat of arms stamped on plateware.
The characteristics that distinguish the 19th century shards from the 20th century ones were mentioned on page Fragments of old bottle glass also serve as indicators of the former dwelling site and may reveal the site’s age. The best way to distinguish old glass fragments from the modern ones is to look at the sun through the glass.

Yoghurt may have made it on to the menu for North Africans around 7, years ago, according to an analysis of pottery shards published today in Nature 1. The same team had previously identified the earliest evidence for dairying in potsherds nearly 9, years old from Anatolia 2. But the findings from 7, years ago still predate the emergence and spread of the gene variants needed for the adult population to digest the lactose found in milk, says biomolecular archaeologist Richard Evershed of the University of Bristol, UK, who led the study with archaeological scientist Julie Dunne.
He suggests that making yoghurt may have made dairy products more digestible. The Nature podacst team talks to Richard Evershed about finding 7, year old milk in clay jars. Although today this area is in the Sahara, 7, years ago it would have been more lush landscape capable of supporting dairy animals. The Takarkori shelter and others nearby are home to vivid and colourful rock art depicting cattle, some with full udders, and even pictures of people milking cows, but these images are nearly impossible to date precisely.
Archaeologists have also found fragments of domestic cattle bones at these sites, but these do not indicate whether the animals were kept for meat, dairying or other uses. Evershed and Dunne hoped to overcome these problems by examining fat residues left on the pottery shards. The researchers examined 81 shards, using mass spectrometry to identify specific animal fats and using the relative levels of carbon isotopes to pick out more exactly the origin of those fats in 29 of the samples.
Of those 29, at least half contained fats came from dairy foods. Carbon isotopes from milk fat can also point to the sorts of food the dairy animals ate, as different plants incorporate varying amounts of carbon relative to carbon
Learning from Pottery, Part 1: Dating
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.

Native Americans have made ceramics continuously in Virginia for more than 3, years. Pottery manufacture in North America first arose more than 4, years ago in the coastal plain of Georgia and spread north from there. Pottery production was a cottage industry, conducted by families with the knowledge of manufacture handed down from mother to daughter. Archaeologists have defined more than 60 Native American wares applicable to Virginia, recording the variables in vessel size and shape, temper, surface treatment and decoration of pottery from BCE to the present.
This wealth of pottery information provides archaeologists with ways to date sites, and to describe Native American social groups and interpret their interaction, movement, blending, and fluidity. Since the early 20th century, archaeologists have searched for the earliest ceramics in Virginia, discussed their origin of manufacture, and debated their impact on developing Native American societies.
Three radiometric samples yielded an average uncorrected date of BP. But, where did the idea originate for the earliest pottery in Virginia? There are two possible interpretations: 1 the technology evolved locally as an independent invention drawing inspiration from the manufacture of earlier containers such as soapstone bowls, and 2 pottery manufacture evolved elsewhere and was introduced into Virginia. Archaeologists have noted the close resemblance of early pottery and carved soapstone containers, which were manufactured in Virginia by BCE.
Native Americans fashioned soapstone into thick heavy oval and round shaped containers, a few appearing like mortars, but also rather elegant, thin bowls. Black smudges on soapstone vessels indicate that they were used for cooking. Soapstone vessel manufacture was limited to a few places in Virginia where the stone occurs naturally.
