How do you burn a candle?
Trim the candle wick to 1/4 inch prior to each use, light in an area not close to drapes or hanging objects, and that is also not very drafty. Allow the candle was to melt all the way across the jar each burn to prevent tunneling, whent the candle burns only a narrow hole, and unsed wax is left on the sides. Never leave candles unattended. Burn candle for 2-3 hours at a time, then allow the aromas to mellow in your space.
