Candle care:
Trim the wick! You must always trim the wick to 1/4” before lighting, including the first burn to ensure a safe, even burn. You must allow the candle to reach a full melt pool (where the melted wax has reached the sides of the jar) for the first burn to prevent your candle from tunnelling.
 

A candle should not be lit for more than 4 hours at a time and never leave a lit candle unattended. Discontinue burning the candle when 1/4 inch of wax is all that remains in the jar.
