We recommend burning for 3-4 hours at a time. Allow the melted wax to reach the edges of the jar to prevent wax from building along the sides of the jar and tunneling, especially with the larger size. Never leave a candle burning unattended or within reach of drafts, pets, or small children. Candle jar will be hot after burning, so allow wax to cool completely before handling. And of course, don’t forget to trim your wick to 1/4“ (.6 cm) after each burning for best results.
