ABSTRACT:
Candles are cast in multiple, tubular, upright molds set in a housing having a normally horizontal top plate, the molds having spherically arcuate top end portions which slightly project beyond the top plate so that a unitary body of molten wax which initially fills the molds and covers the top plate shrinks during its solidification sufficiently that the top end portions of the molds are exposed, and the wax in the molds pulls away from the wax on the top plate, whereby manual finishing of the candle ends may be avoided.
