The end of the twisted wick is fastened to the stick on the top of the mould, and is drawn by a piece of hooked wire, through each mould in succession, leaving a loop outside the bottom points of the mould; the loops are secured there by the bottom stick passing through them; the wicks are to be drawn tight and the last end tied to the upper stick.

The melted tallow is then poured into the moulds and allowed to stand about 6 hours in a cool place, after which the bottom stick must be taken out of the loops, and the candles withdrawn from the moulds. The tallow should not be heated much more than is necessary to melt it.
