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.

Hello there, My grandad found an old piece of pottery sticking out of a molehill near the site of a Middle Age church which is no longer standing (I never found out where, only that it was near an old medieval church site). I've never been able to work out what it is, but it is hollow and looks as if it once had handles. My initial thought was a candle holder but i'm no expert. There is the remnant of an indented design on it and it seems to be glazed white. I don't think it is Middle Age but it does seem rather old and I'd love someone to advise as to what it is if possible please. It stands up and looks to be made from some sort of stone, rather than pot, but again, I'm no expert (height 4.5cm width 3cm). Happy to share photos if possible. Thank you very much.

I found a large part of an old reddish clay flower pot under the original 9thgolf green at the world's oldest golf course. during reconstruction, The golf green has never been dug up before and the flower pot looks to have been used as a golf hole cup. Inside the flower pot, it has discolouration and it has wear in the bottom centre hole where a small golf pin would have been placed. Iam trying to get a date of the pot as this will tell us when the golfers stopped taken sand out of the hole to use as a tee to play their next shot. Do you know how I can get adate to pot?

I’ve recently inherited a plate, it’s age 1865 thats been worked out through the stamp on the back however it has the ‘makers’ stamp THE RAOLIN GARDNERS’ which seems to be unheard of through the internet can’t find anything. If anyone can help give any information about this piece, value etc, it would be gratefully received. Thank you

I have an earthenware plate, blue and white, flowers and leaves round rim, no markings, has spiderings throughout and a few imperfections in the glaze. Bird, perhaps a Jay, flowers could be peonies, though that's only through looking online, so I may be wrong, could be cherry blossom! There is also a dragonfly/small winged beastie in the air and a round fruit with leaves on (perhaps apple with bit taken out?) at the top of a branch. Few very dark blues round rim, dark blue solid leaves within, flowers light blue lines. Very curious, help appreciated! Thank you ??

Alisa - 22-Apr-19 @ 7:34 AM
I found a small piece of potary with a lot if wear and lots of small markings. Looks like there was handles on it and one point and they broke off and the areas of where they used to be are so soft and smooth so i think this price os very old. The clay is a blueish black and the glazing looks very different from any ive seen. Small tiny marking underneath that looks like a flower almost?..really pretty design. I would really love to know exactly how old this peice is.

A Greek wine cup An early flagon (would like to know rough age if genuine) A Roman glass scent bottle. I would really appreciate your experiences opinion on these items, if you can help please let me know and I’ll get some pictures sent over. If you are unable to help, could you point me in the direction of somebody who could? Thanks in advance Chris white.
