On your first lighting, please allow the wax to melt to the edge of the container.  Expect some hang up with this being a coconut soy wax.  You will get a full melt pool at about the 3rd or 4th burn.  Trim the candle wick to 1/4 inch before each burn.  Remove any fallen pieces of wick from the candle before lighting.  Burn your candle for no more than 4 hours at a time.  As your candle burns down, it gets less oxygen causing your flame to get larger and increase the possibility of soot.  Please extinguish your candle, trim the wick and relight.  Stop burning when only 1/4 inch of wax remains.
