ART 295 – Ceramics : Hand Building: Home

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.

Radiocarbon dating: radioactive carbon decays to nitrogen with a half-life of years. In dead material, the decayed 14C is not replaced and its concentration in the object decreases slowly. To obtain a truly absolute chronology, corrections must be made, provided by measurements on samples of know age. The most suitable types of sample for radiocarbon dating are charcoal and well-preserved wood, although leather, cloth, paper, peat, shell and bone can also be used.

Because of the somewhat short half-life of 14C, radiocarbon dating is not applicable to samples with ages greater than about 50, years, because the remaining concentration would be too small for accurate measurement. Thermoluminescence dating: this method is associated with the effect of the high energy radiation emitted as a result of the decay or radioactive impurities.

Ceramics can be poor sources for dating sites if used without considering the cultural contexts in which they are used, yet ceramics are the artifact.

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.

The Handbook of Texas is free-to-use thanks to the support of readers like you. Support the Handbook today. The history of pottery making in Texas may be divided into two broad eras. Central and South Texas pottery was heavily influenced, if not derived from, the first two. The earliest Texas pottery ca. This early pottery includes bone, clay, and sand tempered pastes, as well as sandy pasteware. Plain bone-tempered pottery in the Sabine drainage and Toledo Bend areas may reveal a relationship to early cultures in Arkansas.

Williams Plain ca. It is absent from the Western Sabine and Neches-Angelina basins. After A. Clay and bone tempering continued as the primary technological tradition until its replacement by shell tempering ca. Caddoan pottery also occurs as trade ware in east Central, Southeast, and possibly north Central Texas. North Central Texas received influence from several directions.

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.

Archaeologists have access to various techniques for dating different pottery styles, objects that belong to a specific period (eg, the historic.

Chinese pottery , also called Chinese ceramics , objects made of clay and hardened by heat: earthenware , stoneware, and porcelain , particularly those made in China. Nowhere in the world has pottery assumed such importance as in China, and the influence of Chinese porcelain on later European pottery has been profound. The earliest evidence for art in any form in ancient China consists of crude cord-marked pottery and artifacts decorated with geometric designs found in Mesolithic sites in northern China and in the Guangdong-Guangxi regions.

The dating for prehistoric culture in China is still very uncertain, but this material is probably at least 7, or 8, years old. The art of the Neolithic Period represents a considerable advance. The Yangshao Painted Pottery culture, named after the first Neolithic site discovered in , had its centre around the eastern bend of the Huang He Yellow River , and it is now known to have extended across northern China and up into Gansu province.

Yangshao pottery consists chiefly of full-bodied funerary storage jars made by the coiling, or ring , method. They are decorated, generally on the upper half only, with a rich variety of geometric designs, whorls, volutes, and sawtooth patterns executed in black and red pigment with sweeping, rhythmic brushwork that foreshadows the free brush painting of historical periods. Some of the pottery from the village site of Banpo c.

Dating for the dominant phase of the Yangshao culture may be put roughly between and bce. Over this span of two millennia the Yangshao culture progressed generally westward along the Huang He and Wei River valleys from sites in central China, such as Banpo, to sites farther west, such as Miaodigou, Majiayao, Banshan, and Machang. The art produced at these villages exhibits a clear and logical stylistic evolution, leading from representational designs to linear abstraction the latter with occasional symbolic references.

The last major phase of the Neolithic Period is represented by the Longshan culture , distinguished particularly by the black pottery of its later stages c.

Abundant, easy to identify, date and quantify, ceramics are one of the more ubiquitous types of finds on archaeological sites from the Neolithic period onwards. The Archaeology Department at Durham hosts a cluster of researchers working on ceramics using a broad range of approaches. Our interests stretch across almost all periods, and cover large parts of Europe, Africa and Asia.

For Historical archeologists, ceramics are a diagnostic tool for dating because many English ceramic types can be dated to within 5 or so years.

Radiocarbon dating is a standard technique, but what if your artefacts are inorganic? Rachel Brazil finds out how to accurately age pottery and even metals. Dating archaeological finds still routinely relies on typology and stratigraphy — what an artefact looks like and the context in which it was found. The introduction of radiocarbon dating in the post-war years provided a route to direct dating for organic material, but there are still few dating option for inorganic materials such as ceramics and metals.

In recent years several pioneering groups have been developing new approaches, based on chemical changes that can predictably mark time. Until recently, most dating methods made use of nuclear decay. In geology, radioisotope techniques have been used for over years , but radiocarbon dating for archaeological time-scales began as a result of scientific advances made in the Manhattan project, during world war two.

2. Background

In the archaeology of South Asia, pottery has been studied mainly to establish chronological and cultural typologies. Different pottery ‘wares’, have been identified in order to mark periods of time and sometimes the existence of particular cultural groupings in particular areas at those times. To this end, classifications have been based primarily on the most predominant formal technological and decorative characteristics of the potsherds themselves. In the pottery reports of excavation monographs dating from the 19th century to the present day, we find wares being defined on the basis of four main visible characteristics: the colour of the potsherd, the texture of the clay, the firing mode, and its surface treatment for further discussion, see Sinopoli

THC’s Historic Sites. Ceramic fragments are one of the most common finds during archeological investigations. Ceramics, especially those fired at high temperatures, are extremely durable. They are able to hold up against weathering and can withstand being buried for long periods of time. Because of this, ceramics are an excellent artifact type to use for analysis.

These archeologists can also gauge the extent of trade networks or better understand food preparation, storage, and eating patterns. There are also some ceramics that enable archeologists to make more specific predictions. Ceramic pieces that contain registry marks offer a great deal of information. Registry marks can be found impressed or stamped onto ceramic or glass, and they are an indication that the object was designed and manufactured in Britain between the years — The British Patent Office issued a diamond mark and registration number when manufacturers submitted their work for registration during that time period.

These diamond marks indicate the class of the material, but they also indicate the exact date that the design was registered. The British National Archives retains a record to this day of all ceramics registered. Those records contain a sketch or picture of the pattern, the name and address of the designer, and the number of items being registered known as a parcel or bundle. Willing researchers can discover a host of information from a small mark on a piece of pottery.

All rights reserved. Relative techniques were developed earlier in the history of archaeology as a profession and are considered less trustworthy than absolute ones. There are several different methods. In stratigraphy , archaeologists assume that sites undergo stratification over time, leaving older layers beneath newer ones.

Archaeologists use that assumption, called the law of superposition, to help determine a relative chronology for the site itself. Then, they use contextual clues and absolute dating techniques to help point to the age of the artifacts found in each layer. Learn how archaeologists dated the earliest metal body part in Europe.

Objects can be grouped based on style or frequency to help determine a chronological sequence. Relative dating has its limits. For a more precise date, archaeologists turn to a growing arsenal of absolute dating techniques.
