Bottle oven

A bottle oven is protected by an outer hovel which helps to create an updraught. The biscuit kiln was filled with saggars of green flatwares (bedded in flint) by placers. The doors (clammins) were bricked up and the firing began. Each firing took 14 tons of coal. Fires were lit in the firemouths and baited ever four hours, Flames rose up inside the kilns, heat passed between the bungs of saggars. They controlled the temperature of the firing using dampers in the crown. The temperature was gauged by watching the contraction of bullers rings place in the kiln. A kiln would be fired to 1250C

The biscuitwares are glazed and fired again in the bigger glost kilns- again they are placed in saggers, separated by kiln furniture such as stints, saddles and thimbles.

The enamel (or muffle kiln) is of different construction- it fired at 700C.

The pots were stacked on 7 or 8 levels of clay bats (shelves). The door was iron lined with brick.
