Potsherds Archaeology Extant Ceramic

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.


Ceramic and pottery are often interchangeable archaeological terms but they do have specific differences. Stoneware and earthenware pottery are terms likely to be affixed in archaeology, to rudely made utilitarian items such as bowls, cups, jugs and pots. The clay in these everyday pieces has not been fired at high temperatures, was easy to make and therefore, less expensive. Extremely high-fired clay that fuses a glaze onto the body is generally referred to as ceramic. Ceramic artefacts are often very rare due to their thinner, brittle construction being easily broken.

The study of pottery can provide insight into the manner of how pottery items were manufactured in antiquity. In order to analyse pottery the expert in ancient ceramics will consider the known classifications of pottery and attempt to interpret artefacts in terms of their chronology, function and tradability. To achieve this task, specialist laboratories have been established in major universities, museums and in business using traditional and modern examination methods.

Process of Analysis

Firstly, the ceramic expert will identify and record all of the artefacts received from the digging site. It may be necessary to re-classify items that have been incorrectly labelled by inexperienced workers at the site. The next step is to provide a sensible date-range for batches of sherds and other artefacts. Dates fall into specific categories as defined by the chart of archaeological time periods introduced in 1819 by Thomsen's 'Three Age System' of Stone Age, Bronze Age, and Iron Age. The years before 5000 BC are believed to be the pre-pottery period, the first primitive stonewares being found in the late Neolithic age.

A Complex Jigsaw Puzzle

Undamaged artefacts are easy to recognise and classify. Potsherds, on the other hand, are like a tricky, three-dimensional jigsaw puzzle where all the pieces might not even be there. The reconstruction of a ceramic artefact by piecing together all of its sherds is a meticulous undertaking.

When an ancient settlement was violently conquered the victors would often destroy the buildings by pulling down its walls and/or totally razing it to the ground by fire. This resulted in great building stones being hurled down onto the ceramic items of everyday use. Most were shattered beyond recognition. Like a forensic investigator the ceramic expert needs to assemble all of the available sherds and carefully piece them together to reconstruct the original. Where missing pieces create a void, making a modern replacement piece fills the gap.

Dating Pottery

Have you ever marvelled at just how much information appears to be known about an antique when it is turned upside down by Antiques Roadshow presenters? Modern ceramics tell a lot about their history from the maker's marks usually found on the underside. Ancient pottery have very few marks, thus the dating of antiquities is more like detective work.

The analyst must search for clues in the historical references learned from lengthy studies of early ceramics. The raw material used, the process of forming or moulding, the colours applied, the style or shape, any patterns or inscriptions, the firing method and finally, any wear or usage marks, are all considerations necessary before an accurate estimation of the item can be proposed.

Learning More About Buried Cultures

Potsherds from a digging trench, by their style, form and colour will assist researchers to identify the culture extant at that time, provide a date for the stratum level and add to the chronological record further information about the buried civilisations slowly being uncovered.

I have an approximately 8 inch tall pot with square and rectangular designs in cream, black, brown and rusty colors that have been piped on it. Round at the base narrowing upwards then flaring out at the top. It has no lid. It has 3 painted male figures, upper body only, at equal distances one third of the way up from the base at the widest part with their arms spread as if they are supporting it or holding something back.These are painted also. It has been used to burn something inside at some time. Remnants are still in it and look as though someones fingers may have trudged throughbefore it dried. The remnants feel as hard as concrete and are light brown in color. No markings on the bottom. Any ideas on who may have produced it?Or what it was used for?

I dug a hole in my yard about the size of a basketball and found 30 pieces of pottery. They are nicely sized pieces. This is in Phoenix just south of the salt river. I would like to know how old it is as I found it about 8" down in hard packed soil. It's all over my yard.

Hi, I am a life science researcher. One of my hobbies is to routinely go to auctions and buy unique items, including antiques. Recently I bought two pieces of pottery that seem to have a lot of history associated with them and since I have no clue about anthropology. One of the pots has a bluish reddish pigment coating and has a leaf on side top and elephants on a relief (crude reconstructions). The other pot is more flatter with a narrow neck and has yellowish red pigment coating and has horses on the sides. Does anyone know which era these pots belong and also, the civilization and age if known. Many thanks for your help in advance. Please let me know if you have any questions. Kind regards, Moonie1977

bdaniels2234 - Your Question:
Hello I posted about the vessel I think that's what it is but if anyone could put me in the right way of helping I would greatly appreciate. It's patina is perfect and it looks like it was dug up there seems to be reminants of yellow and red paint. But the way the clay or dirt is in the cracks of the design on the neck and inside it it looks to be old and it would have taken awhile to form the way it is in there. I can send all the pics you want if anyone wants to see. It's heavy and you can tell it's not something mass manufactured and it's old. Thanks again,Brady

I was gifted a piece of native american Indian pottery about ten years ago and find that I need to sell it to help with living costs. I would like to know if you could identify the tribe and date it so I can figure out how much to ask for it. I believe there is gold dust mixed in to the clay and it was put near or on the fire and probably helped keep it hot longer.

I was listening to a Keith Jarrett concert on YouTube and he mentions at one point - "There's a Koreon method of glazing small pots and it is a half totally conscience, half totally accidental process, where they know what might happen but refuse to make anything happen particularly. And I would call that an influence on my music." Can you help a laymen and identify for me what Keith Jarrett is describing. Thank you.

I have found myself holding a box of it looks like from 3 different items of pottery, broken pieces. Some are hand painted, there seems to be two covers or lids?, one piece looks decorative, and others are plain. I can send you photo's - I know nothing about this pottery but in this box was a small remnant of paper which says "viking" and has some other info on it. I have no history where these came from, but I feel they may have some historical something? The previous owner of these items passed away, they were thrown in this box and left outside. Please advise.

As a student of anthropology , i have to go to an archeaological exploration or more precisely re-exploration in the archaeological sites of Pirtala of Sagardighi at west-bengal in India. i found some potsherds of neolithic period, those pot sherds are both hand made type and wheel made. A ceramic pot's base with designs of firoza colour and blue-green and also have striking resembling features of Mughal Period in Bengal had found. that experience was mervellous.
