October’s find of the month was found just this week; during works around the forthcoming Chadwick Centre, at the International Bomber Command Memorial Site. Several large pieces of waster pots were found in a pit near to where three kilns had already been excavated back in 2014. Hopefully we could find another one!
We started work at the site in 2014. During an excavation in 2014, the three kilns were uncovered and have all been dated to the Romano-British period: probably towards mid to late 3rd Century. They are all fairly small, indicating that they were more likely to have been small subsistence kiln’s filling the needs of the local area, rather than a business. Earlier work has shown that the area has generally been in agricultural use; with multiple corn dryers, which would link into the local use of the kilns in a rural area.
A pottery kiln normally consists of a dome shaped superstructure which keeps the heat in, and around, the pottery being fired. A long triangular or oval shaped stokehole pit lies in front of the circular oven , which was where the fire was originally started and also where the ashes would be pulled out of the kiln into. Stokeholes are often very distinguishable due to their black, charcoaly appearance. Throughout the kiln structure you can find wasters. Wasters are piece of pottery that have not made the grade for whatever reason; be it a deformity such as a crack, a poor firing reducing the integrity of the structure, or an air bubble within the clay. You are less likely to find a complete rim of a vessel, which is why the one seen here is particularly exciting You can see on the picture of the little base, a small depression which would have been an air bubble that was trapped in the clay but burst during the firing. This not only creates a poor finish but it weakens the pottery.One kiln found during the excavation had very little pottery wasters near, or in it, which suggests that it might have been used for something other than pottery. It could have been a bread oven, or as the more imaginative of us like to think; a pizza oven!
