Things You'll Need
Heavy duty freezer bag
If you regularly burn candles, then you know how often you have remnants of old candles that are no longer big enough to be burned. Instead of tossing these candle pieces away, you can recycle the wax pieces by melting them down to make new candles. One way to do this is to use a boil bag, which sits in boiling water that will melt the wax chunks inside the bag.
Cut up used candles into 1-inch chunks. Discard any used wicks.
Place the wax chunks into a heavy duty plastic freezer bag. Tie the top of the bag loosely with a rubber band.
Fill a pot with water, and place the bag inside the water.
Boil the bag over medium heat until the wax completely melts.
Place weighted wicks inside the candle molds you are going to use.
Tape the rubber band off of the plastic bag, and pour the melted wax into the candle molds until they are nearly full.
Allow the wax to cool completely before using the candles.
