Introduction to Ceramic Identification

This project is meant to be an aid to help with identification of ceramics found on historic period archaeological sites in Nova Scotia. The collection of ceramics included in this database is not meant to be comprehensive, although future expansion of the database is expected at a later time. The focus is largely on ceramics dating from the eighteenth and nineteenth centuries. A bibliography at the end of the ceramic catalogue offers some references for more detailed descriptions of ceramic types. Technical support, bibliographic material, artifacts and computer access were provided by the History Section of the Nova Scotia Museum. Thanks to Dr. Stephen Davis SMU , who provided organization and design ideas throughout the project, as well as moral support. Barton, K.

Dating Techniques In Archaeology

Paste consists of the clay or a mix of clay and any inclusions temper that have been used in forming the body of the ceramic. Decoration is particularly important in identifying and dating post-colonial refined earthenware. We have also prepared an organization chart of ceramics and their characteristics as a visual aid.

Pottery is one of the most commonly recovered artefacts from archaeological sites.

Despite more than a century of relative dating based on typology and seriation 1 , accurate dating of pottery using the radiocarbon dating method has proven extremely challenging owing to the limited survival of organic temper and unreliability of visible residues 2 , 3 , 4. Here we report a method to directly date archaeological pottery based on accelerator mass spectrometry analysis of 14 C in absorbed food residues using palmitic C and stearic C fatty acids purified by preparative gas chromatography 5 , 6 , 7 , 8.

We present accurate compound-specific radiocarbon determinations of lipids extracted from pottery vessels, which were rigorously evaluated by comparison with dendrochronological dates 9 , 10 and inclusion in site and regional chronologies that contained previously determined radiocarbon dates on other materials 11 , 12 , 13 , 14 , Notably, the compound-specific dates from each of the C and C fatty acids in pottery vessels provide an internal quality control of the results 6 and are entirely compatible with dates for other commonly dated materials.

Accurate radiocarbon dating of pottery vessels can reveal: 1 the period of use of pottery; 2 the antiquity of organic residues, including when specific foodstuffs were exploited; 3 the chronology of sites in the absence of traditionally datable materials; and 4 direct verification of pottery typochronologies.

Here we used the method to date the exploitation of dairy and carcass products in Neolithic vessels from Britain, Anatolia, central and western Europe, and Saharan Africa.

If you walk across the area between the hexagonal basin of Trajan and the Tiber, there is virtually no soil because there is so much pottery. And at the moment, I think— at the British School at Rome, at the moment we have something in the region of 75 to 80 tonnes of pottery which have come from the excavation and which we are currently studying and preparing for publication.

And much of it comes from— indeed, most of it— comes from across the Mediterranean basin.

We show that the rehydroxylation (RHX) method can be used to date archaeological pottery, and give the first RHX dates for three disparate.

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.

Application of radiocarbon in the case gives a hope for site dating. Whether carbon dating is possible for pottery or not? It depends. Manufacture of early pottery was closely associated with the technologies in which except for the clay component for plasticity and strength were used organic additives grass, straw, river and lake silt and manure. The presence of this type of ceramic creates the preconditions for successful radiocarbon dating of many archaeological Neolithic sites.

The Oxford Handbook of Archaeological Ceramic Analysis draws together topics and methodologies essential for the socio-cultural, mineralogical, and geochemical analysis of archaeological ceramic. Ceramic is one of the most complex and ubiquitous archaeomaterials in the archaeological record: it occurs around the world and through time in almost every culture and context, from building materials and technological installations to utilitarian wares and votive figurines.

For more than years, archaeologists have used ceramic analysis to answer complex questions about economy, subsistence, technological innovation, social organization, and dating. Each chapter provides the theoretical background and practical guidelines, such as cost and destructiveness of analysis, for each technique, as well as detailed case studies illustrating the application and interpretation of analytical data for answering anthropological questions.

Pottery identification is a valuable aid to dating of archaeological sites. Pottery is usually the most common find and potsherds are more stable than organic.

Rehydroxylation [RHX] dating is a developing method for dating fired-clay ceramics. This reaction reincorporates hydroxyl OH groups into the ceramic material, and is described as rehydroxylation RHX. This weight increase provides an accurate measure of the extent of rehydroxylation. The dating clock is provided by the experimental finding that the RHX reaction follows a precise kinetic law: the weight gain increases as the fourth root of the time which has elapsed since firing.

The concept of RHX dating was first stated in by Wilson and collaborators [3] who noted that “results The RHX method was then described in detail in [1] for brick and tile materials, and in relation to pottery in RHX dating is not yet routinely or commercially available. It is the subject of a number of research and validation studies in several countries. The RHX method depends on the validity of this law for describing long-term RHX weight gain on archaeological timescales. There is now strong support for power-law behaviour from analyses of long-term moisture expansion data in brick ceramic, some of which now extends over more than 60 y.

The amount of water lost in the dehydration process and thus the amount of water gained since the ceramic was created is measured with a microbalance. Once that RHX rate is determined, it is possible to calculate exactly how long ago it was removed from the kiln. The RHX rate is largely insensitive to the ambient humidity because the RHX reaction occurs extremely slowly, and only minute amounts of water are required to feed it.

Sufficient water is available in virtually all terrestrial environments.

Rehydroxylation dating

Historical archaeologists have learned that excavated ceramics can be used to date the sites they study. The most useful ceramics for dating are the glazed, relatively highly fired, fine-bodied earthenwares common since the late eighteenth century. By around , European ceramic manufacturers had begun a concerted effort to mass-produce fine-bodied, durable earthenwares for the world market.

Their overall plan imitated the Chinese, who had already developed porcelain factories for the production of vessels explicitly designed for export. The Europeans also attempted to mimic the porcelain itself by initially producing white-bodied earthenwares with blue decorations similar to those found on the Asian wares. European potters viewed their glaze formulas, decorative motifs, and production techniques as company-owned trade secrets, and because they worked within a competitive commercial environment, they usually kept meticulous records of their patterns,

Decoration is particularly important in identifying and dating post-colonial is a visual guide of historic ceramics created by Joe Bagley, City Archaeologist of.

For those researchers working in the field of human history, the chronology of events remains a major element of reflection. Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.

There are two main categories of dating methods in archaeology : indirect or relative dating and absolute dating. Relative dating includes methods that rely on the analysis of comparative data or the context eg, geological, regional, cultural in which the object one wishes to date is found. This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years.

FLMNH provides a date range of production for this type of ceramic and it states that it Approaches to Material Culture Research For Historical Archaeologists.

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.

Other areas, such as the Upper Gila region, have less securely defined ceramic chronologies, particularly for the — interval following the Mimbres Classic abandonment of the area. Part of the problem is that local populations appear to have been relatively small at least compared to earlier and later time periods , and large numbers of decorated ceramics were not left behind at most sites.

The value of ceramics

View exact match. Display More Results. Aceramic Neolithic groups are more rare outside Western Asia. It is usually subdivided into six periods and is characterized by a variety of subsistence patterns and by a lack of ceramics. The first two periods up to BC represent a subsistence based on hunting.

changes are well documented, ceramics are easily dated and help archaeologists to date sites. The Alexandria Archaeology Museum is said to have the largest.

A mean ceramic date offers a quick and rough indication of the chronological position of a ceramic assemblage South The mean ceramic date for an assemblage is estimated as the weighted average of the manufacturing date midpoints for the ceramic types found in it. The weights are the frequencies of the respective types in the assemblages.

Types represented by more sherds have greater influence in the calculation. Manufacturing midpoint estimates, and the beginning and ending manufacturing dates from which they are computed, come from documentary evidence on the ceramic industry. Here we offer two different mean ceramic date queries. The first provides mean ceramic dates for the chosen level of aggregation.

The second provides ware-type frequencies. The manufacturing date range for each ware type was assigned using traditional documentary sources e. Noel Hume , Miller et al.

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.

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.
