Abstract
A pad eliminatable by heat prior to casting has a patterned surface and a non-porous backing. The pad is sized and shaped into at least part of the appliance and the patterned surface is conformed to the desired bonding surface contour. The patterned surface yields irregularities in the cast bonding surface which increases bondability.
