Disclosed are method and apparatus for forming tab samples of material, such as ceramic, having a metal or ceramic base. A form body comprises a recess between two extending arms and a shelf positioned to face the recess between the arms. A base may be positioned on and anchored to the shelf facing into the recess. Ceramic material may be formed on the base within the lateral confines of the recess as defined by the arms. Opaque ceramic material may be formed on the base as an underlayer of the ceramic sample. The ceramic may be fired on the base, and the finished ceramic sample may serve as a shade sample. Plastic or wax material may be formed on the shelf in a replica of such a base to construct a mold for use in forming the base.
