Wood wicks light trickier than cotton wicks. It is like lighting a fireplace. Sometimes you have to re-lit it a couple of times or hold your lighter close to the wick for more than 10 seconds. For the first burn, allow your candles to burn 2-3 hours to create a full melt pool reaching to the edge of the glass. Keep wood wick trimmed to ⅛” for best results. Before lighting again, gently break off burned edges with fingertips or paper towel and discard. Never leave a burning candle unattended. Once the candle has reached about 1/2″ of wax remaining, stop burning it. Continuing to burn past this point is a fire hazard. Soy wax candles burn slower and are more temperature-sensitive than paraffin candles. It takes a while to finish a tin can so you will enjoy a good scented candle for a long time.
Tin cans can be reused and recycled just clean them with warm soap and water.
