2nd century Pottery kiln No 20. excavated at Sheepen. On the north side part of the clay wall was preserved against the clay of kiln 21 to a height of 3ft 3" from the floor. The central support was of clay blocks and measured 15" long by 5" wide and 12" high. The oven floor had completely disappeared. The structure of the stoke-hole was of interest. In the main it consisted of three heavy cylinders or tubes on each side, filled with clay, and in one case containing a smaller tube, set upright on the ground and embedded in clay. The tubes, or some of them, were continued upwards by columns of faulty colour-coated beakers inverted one upon the other. The uppermost vessels were shattered, and there was no indication of how this arrangement was finished at the top. The whole was luted together with clay, most of which had fallen away. In this case the kiln does not appear to have been dismantled and the pottery found in immediate association probably belonged to it.<1><2>
