Reconstruction of one of the Medieval ovens excavated at Sneyd Green

Kilns now used coal instead of wood as their fuel and the result was the development of multi-flued kilns. As coal takes time to heat up, several fire mouths were needed to ensure the pots reached their correct firing temperature. Few actual superstructures survive, as they would have been of a temporary build and erected for each firing. However, the bases of some of these kilns have survived  but they are few and far between. This period also saw the first use of specific wares being made for the soul purpose of housing vessels during firing.
