Trim your wick 1/4 inch before each burn. A large flame may indicate that your wick is too long.
Trim to ensure a clean burn.
The first burn
The first time you light your candle let it burn 1-4 hours until the pool of wax reaches the edge of the glass, this will prevent tunneling which will extend the life of your candle.
Do not burn for more that 4 hours at a time.
Discontinue Use Before Empty
Discontinue use of your candle once the remaining wax reaches less than 1/4 to the bottom of the jar.
