A shelf support for a ceramic-ware support structure in which a transverse groove extends across the upper shelf supporting surface to provide a dust trap. The support is intended for use with movable shelves of refractory material and prevents quantities of ceramic dust from falling onto the ware supported by the structure when the shelves are slid into position. Additionally, chamfers are provided on the shelf support and the associated uprights of the structure to reduce the amount of dust abraded from the shelves during insertion and removal.
