Enamel Kiln</Strong>
Decorated pottery was often coal fired in an enamel (or muffle) kiln.
Enamel kilns are much smaller than bottle ovens, and because the whole inside of the kiln is made from refractory material do not need saggars.
The firing temperature is much lower and therefore the firing time is much shorter than the intial firing to harden the ware.
