ABSTRACT:
Apparatus for firing ceramic greenware including a container and a plurality of independently movable granules disposed within the container so as to provide a readily levelable minimum friction support surface for supporting the ceramic greenware. During firing, those granules which contact the greenware move in correspondence with the shrinkage of the greenware so that friction related distortion of the greenware is reduced. The ceramic greenware is fired by a method which includes providing a sufficient depth of granules to permit relative movement of those granules in contact with the ceramic greenware, leveling the surface of the granules, placing the greenware on the level surface and firing the ceramic greenware.
