Ceromancy ~ The art of divination by dropping melted candle wax in a pan of cold water is a old practice. Traditionally, the ritual uses a brass bowl. Water is added to the bowl and a candle is then lit. The melted wax is poured into the bowl and the resulting shapes are interpreted by the reader.
-A bowl of water.
Today there are many ways to a ceromancy reading. Usually a candle is blessed or a chant is done while holding the candle. Herbs can be added to the water to help the reading along.
Watch the candle flame when you lit it. It will tell you something about the mood of the reading. A fast burning candle is usually a really good sign. A candle that hisses, sizzles or makes other noises can mean that your going to get a important message. A candle that burns really slowly is usually not a good sign. If the candle won’t light at all you should try to do the reading at another time.
When doing a reading about two people (like love or friendship) you can take 2 candles and tie them together with a colored ribbon. (red for love, yellow for friendship, ect) Watch how they burn if one candle is buring faster or dripping wax over the other candle can mean one persons desire is bigger than the other, or a friend is putting pressure on another friend, ect.
You can use any kind of candle but I usually keep come candle apart I only use for divination. I won’t use them for other things. Taper candle you can just hold above the water and let it drip down into it. A pillar candle I will usually let burn for a little while than dropped the melted wax into the water. Than take a spoon and fish the wax out of the water.

As far as I know there are no books specifically on Ceromancy. You might find some info in Pagan books or books on Divinatory Practices.
