Pakeha Ceramics as Dating Tools Naomi Woods Ceramics are one of the most useful sources of information in historical archaeology, especially when it comes to dating activity at a site. Despite this, they have been somewhat neglected within the field here in New Zealand.
Chemical clocks for archaeological artefacts
Part of: Society for Historical Archaeology The origins of the New Jersey stoneware industry — and perhaps even the American stoneware industry — seem to lie in the late 17th century with an awareness that high-grade clays suitable for making dense, hard, durable pottery were present in the South Amboy area of Middlesex County in the Province of East Jersey. As early as , there are indications in the court records of Burlington County in West Jersey that such clays were known to early settlers.
This clay source was presumably Salt-glazed stoneware vessels and sherds found on 19th century sites are generally assumed to be of North American manufacture, unless they are highly decorated, but sherds from 18th century sites are usually identified as German made.

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.

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.

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.

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. Because of the half-lives of U, nd, and 40K are very long, their concentrations in the object, and hence the radiation dose they provide per year, have remained fairly constant.
The most suitable type of sample for thermoluminescence dating is pottery, though the date gotten will be for the last time the object was fired. Application of this method of age determination is limited to those periods of pottery and fired clay availability from about BC to the present. Beta Analytic, Inc. University Branch S.

Ceramics Identification is Clear as Mud
One of the most numerous types of artifacts that we find on campus includes various types of ceramics. This range from domestic whiteware plates, bowls and cups to more industrial earthenwares for pipes and flower pots. The type of pottery and the decorations on it are important towards not only dating a site, but also for understanding the economic and social status of an area.
For example, wealthier individuals tend to have porcelain dining sets with intricate designs whereas the lower classes had whiteware sets with less detailed patterns. Luckily, the identification of pottery is a fairly straightforward process based on looking at the paste, glaze and decoration. Since the pottery we find is often in smaller sherds or pieces, it is important to describe the artifact as fully as possible in order to gain as much information as we can from it.
Starting from questions about the nature of cultural diversity, this paper examines the pace and tempo of change and the relative importance of continuity and discontinuity. To unravel the cultural project of the past, we apply chronological modelling of radiocarbon dates within a Bayesian statistical framework, to interrogate the Neolithic cultural sequence in Lower Alsace, in the upper Rhine valley, in broad terms from the later sixth to the end of the fifth millennium cal BC.
The rate of ceramic change, as well as frequent shifts in the nature, location and density of settlements, are documented in detail, down to lifetime and generational timescales. This reveals a Neolithic world in Lower Alsace busy with comings and goings, tinkerings and adjustments, and relocations and realignments. A significant hiatus is identified between the end of the LBK and the start of the Hinkelstein group, in the early part of the fifth millennium cal BC.
On the basis of modelling of existing dates for other parts of the Rhineland, this appears to be a wider phenomenon, and possible explanations are discussed; full reoccupation of the landscape is only seen in the Grossgartach phase.

ANT – Historical Archaeology. Uses of Ceramics and other domestic artifacts! Introduction Rural and Domestic Life: In progress. Although there are some written descriptions of life on the frontier, archaeology is a key source. Immigrants took land grants, cleared forest, and built log houses. After their farms became well established, they replaced their houses with frame ones.

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.
Creamware, Pearlware, Whiteware left to right. Ceramics provide an effective means of dating historical sites or a particular soil layer because stylistic elements change over time. There are certain wares and decorative techniques that have very specific date ranges that archaeologists can utilize when dating a site if other non-diagnostic artifacts are present.
Here are our identifications for the ceramics we posted yesterday. For more info on identifying and dating historic ceramics, visit.
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.
Starting approximately in 9, BCE, clay-based ceramics became popular as containers for water and food, art objects, tiles and bricks, and their use spread from Asia to the Middle East and Europe.
