Updraught kiln

An updraught kiln is:
 * 1) a kiln in which the heat enters the kiln chamber from the bottom and passes through the ware (Ries 1912)
 * 2) an intermittent kiln in which the hot gases rise up through the bricks to an open top. Newcastle, Suffolk and Scotch kilns are updraught kilns (Brunskill 1990)
