Abstract: To form a candle blank, a volume of hot liquid candle wax is injected into a generally cylindrical chamber having a length and a diameter. The hot liquid candle wax is then cooled and the length of the generally cylindrical chamber is reduced as the wax cools, so that the volume of the chamber remains substantially that of the volume of the shrinking wax. By operating in this manner, there is no room for a void to form. An apparatus to carry out the process comprises a block, a piston, a gate, a means to inject the wax, and a means to move the piston so that it follows the shrinkage of the wax as it solidifies. The block defines a generally cylindrical mold chamber for the candle blank. The mold chamber has a generally vertically positioned longitudinal axis, an upper end, and a lower end. The piston is positioned in the chamber to slide from the upper end to the lower end of the chamber. The gate is positioned at a lower end of the chamber.
