When you first light your sacred scented candle, allow the melted wax pool to reach the sides of the jar before putting the candle out.  This will help prevent wax from building up on the inside of the jar, as well as prevent tunneling of the candle during future burns. We recommend a burn time of around 3 hours, and no more than 4 hours.  Candle jar will be hot during and after burning, so allow the wax to cool before handling the jar.
