Get the ultimate home fragrance experience by taking good care of your scented candle and prolong its lifecycle. Keep your candle from tunneling down the middle by creating a melt pool from the very first burn: Allow the wax approximately 1-2 hours of burn time and make sure the wax has turned into a complete melt pool before extinguishing. A melt pool is when the candle melts from edge to edge of the glass jar. Simple, yet effective!
