In the 16th century the celebrated Venetian courtesan, Veronica Franco, was hauled before the inquistion for practicing ceromancy to discover the idenity of a thief in her household. She initially beat the charge of heresy by admitting she had particpated in the ceremony but didn't believe in it. (One must hold a false belief in order to be a genuine heretic.)
Most people simply light a taper and tip the candle at about a 145 degree angle over a pan of water to allow the wax to drip into the cold water.
One Italian method of ceromancy is recorded in Judika Illes, The Element Encyclopedia of 5000 Spells, 2004 (p. 307)
Bind two tapers--not dripless beeswax candles--with scarlet ribbons. Set these candles standing up right in a pan of cold water. Place in the water, nettle leaves,cumin seeds, three rose hips, and a few sprigs of rue.
Light the candles. Observe the wax dripping into the cold water. Interpret any shapes formed by the hot wax solidifing in the cold water. The ultimate interpretation of what a shape is and what it means is up to you.
Below are some "commonly accepted" meanings for the shapes that sometimes result. I do not know if any of these meanings are associated with Italian folklore or not.
