ABSTRACT:
A mold for candles having a three dimensional surface pattern is formed of a split elongated shell having juxtaposed edges detachably connected together. Lining the shell is a split sleeve having an inner surface bearing the selected three dimensional pattern and longitudinal edges in close face to face juxtaposition. The sleeve is formed of silicone rubber initially formed in its final molding configuration so that after molding, the shell may be removed from the sleeve and the split sleeve may be peeled back from the molded article, resiliently returning to its mold configuration when the article is removed. Flexibility of the sleeve permits it to be removed from undercut surface of the pattern.
