Burn candle for extended periods of time.
Burn candles roughly 1 hour per inch in diameter (e.g. 3" pillar should be
burned for at least 3 hours per session.) Burning for extend time ensures
that the wick burns the candle evenly out to the edge. This also helps to
avoid tunneling and relighting issues.
Keep the wick trimmed to 1/4".
It's important to trim the wick during or immediately after burning your candle.
The wick itself becomes potentially fragile when cooled do to the amount of
beeswax still remaining in the wick. Trimming a cold wick may break the wick
off, making relighting it difficult.
