Things You'll Need
Double boiler or two saucepans
Luster or clear crystals
Jar or mold
Wax will harden when cooled, but that wax can soft and pliable. Soft wax will burn faster and in an unpredictable manner. Candles that are made of soft wax will allow the wick to freely move around the container it is placed in. The wick can be lost, and the candle will be useless thereafter. Additives can be placed in the wax when melted to create a denser, longer-burning wax.
Melt the wax in a double boiler at a medium temperature setting. Do not get water in the wax or on the wick. Water will leave pockets in the wax and cause a crackle when burning.

Place the additive ingredients into the wax, calculating the amounts in relation to the quantity of wax by weight and volume. Add 10 percent of stearin and one tablespoon of luster crystals or clear crystals per one pound of wax.
Pour the wax into the intended container. Place the wick; make sure it is centered. A centered wick ensures an even burning, retaining the life of the candle. Allow the candle to cool and set.
Trim the wick, leaving a ¼-inch section; make sure the wick is standing straight up and centered. Light the candle.
