You'll find chime candles in your local metaphysical shop, on Ebay, and many other places. Chime candles are small taper shaped candles that burn without dripping and are completely consumed before burning out. They are used for spell craft most usually.
Chime candles come in many colors and you can purchase holders for them, but most serious practitioners will tell you that crumpled aluminum foil works well as a chime candle holder. Candle magic is a worthy subject and I don't mean for a second to portray it as simple. However, as with all spell craft, the magic is in the intention, so the simplest of chime candle spells can be very effective.
Generally, the simplest candle magic has to do with diminishing something that is represented by the wax that is burned away by the candle flame. Color is a matter of taste but there are some common correspondences. You can look them up on the internet. Just know that you aren't "doing it wrong" if you use a color that someone else thinks is "for something else."
Sacred space is created and the candle is "dressed" and other wise prepared for the working. To dress a candle, sacred oil (blessed oil) is spread thinly with a finger from stump end to wick end in long straight strokes. Do this all around the candle. However, if your spell includes inscribing your chime candle with symbols or words, do this before "dressing" the candle with oil for easiest handling.
This article isn't meant to explain spell craft. If you need to study more to understand sending your intention into the ether, then I recommend reading "The Compleat Magickal Path," by John Cross as an excellent beginner treatise. Raymond Buckland's essential candle magic book is a great resource as well.
Once your candle is "dressed" and inscribed if desired, place it in a holder and light the wick with intention, usually involving a rhymed incantation of your own writing. The incantation should describe *in detail* the desired outcome of your spell working. You can close your circle and place your candle somewhere safe to burn. Watch the candle carefully until it burns down. If any wax remains (it won't usually), bury it. Think no more on the spell. It is done.
