  Candle Burning 101

The first time you light a candle, burn it one hour for every inch of the diameter.  This will allow the pool of wax to extend to the outside rim and prevent your candle from forming a "canyon or tunnel" in its center.  Burning your candle this way will also set its memory for future burns.  Each time you re-light the candle it will "remember" to burn out to the rim of the container.
Keep you wick trimmed!  This is essential for a clean, smoke free burn.  Many people complain about candles that smoke and this can be eliminated by trimming the wick to 1/4" inch every time right before you burn your candle.  This is true for all types of candles.
If your candle is smoking despite trimming the wick and checking for debris in the melt pool, extinguish the candle immediately.  Trim the wick again a little more and allow to cool before relighting.  The smoking will stop.  With a quality candle, you shouldn’t have problems with smoking, but it is worth remembering that scented candles may smoke more than unscented candles.
When you burn a highly scented candle, sometimes "mushrooming" will occur on the wick.  Treat this as a friendly reminder that you need to trim the wick. 
Candles need to breathe.  If you burn a candle in a small room, it is likely to smoke.  Please consider the size of your room when you display your new candles.
Never "blow out" a candle.  Blowing will spray the wax everywhere and cause the candle to smoke.  Not to mention may cause a fire.  The most effective way to extinguish the flame of a candle is to use a wick dipper (we also sell these).  This not only cuts back on smoking, but it also primes your wick for the next burning.
