The initial burn of your candle needs to be approximately 3 hours to form a melt pool that is edge to edge and about 1/4" deep. We recommend that subsequent burning can vary in duration, but always needs to burn long enough to produce a full melt pool.
**We do NOT recommend burning your candles for more than 4 hours at at time. If you insist on burning your candles continuously, be sure you are extinguishing the flame every 3-4 hours and trimming your wick for the safest burning.**
