Under no circumstances use a candle which has already adorned a dinner table or been used as a bedroom candle or night-light. There is a very good occult reason for not using anything but virgin materials in magic. Vibrations picked up by secondhand materials or equipment may disturb your workings and negate their effectiveness. Some magicians who are artistically inclined prefer to make their own candles for ritual and magical use. This is a very practical exercise because not only does it impregnate the candle with your own personal vibrations, but the mere act of making your own candle is magically potent.
Specialist shops sell candle wax and molds together with wicks, perfumes, and other equipment.
The hot wax is heated until liquid and then poured into the mould through which a suitably sized wick has already been threaded. The wax is then left to cool and once is this has occured the mould is removed, leaving a perfectly formed candle. Special oil-soluble dyes and perfumes can be added to the wax before the cooling process is complete to provide suitable colors and scents for a particular magical ritual. Once you have purchased or made your ritual candle it has to be oiled or 'dressed' before burning. The purpose of dressing the candle is to establish a psychic link between it and the magician through a primal sensory experience.
