ABSTRACT:
A ceramic workpiece holder for use in kiln treatment of ceramics includes a base member of generally elongated configuration. This base can have two, three or four or more legs and can be formed with an upstanding support post intermediate its ends. Each leg of the base member carries a pair of blade members which can extend in any direction and can especially be placed parallel to its longitudinal axis. The blades can be positioned at an angle or can extend vertically upwardly with the upward edges extending parallel to the horizontal or at an angle thereto. Located in the support post are a plurality of pin members also extending generally parallel to the longitudinal axis of the base member and are spaced apart to define support points. A pair of grooves extend along each leg, one each for holding each blade. These grooves extend further than the length of each blade and are of a length and width to accommodate a blade during expansions and contractions. In use, a ceramic plate to be fired in a kiln may be supported with the edge thereof engaged by the upper edges of the blade members and with a back surface portion engaged by the ends of some of the pin members.
