Avoid excessive burn time, no more than 4 hours is recommended. Trim the wick to 1/4 " tall before every burn to keep the wax clean and burning nicely Burn on a stable, heat-resistant surface away from flammable objects. Do not burn on wood as the candle jar can heat up and cause a burn on non heat resistant surfaces. Never leave a burning candle unattended Candles with dried flowers: please remove or cut down as close to wax level as possible prior to burning Keep out of reach of pets and children Crystals can be left in or taken out prior to burning. Watch the crystal is not in direct flame. If you notice your flame is not burning fully, it's best to remove the crystals and light the candle without obstruction. Allow candle to melt to the edge of the vessel. This prevents future tunneling STOP BURNING WHEN THERE IS LESS THAN 1/4" OF WAX LEFT IN THE GLASS - When the majority of the wax has been consumed, the flame will heat the container making the bottom of the jar hot. To prevent possible heat damage to your container and surface, stop burning after only 1/4" of your candle is left.
