I believe everything in this world needs a little bit of TLC. And your candle is no exception.
Every time you light your candle (including the first time), please trim the wick. Simply snip off the tip. This will help your candle burn evenly.
Always light your candle long enough to get an even burn pool (where the top layer of melted wax reaches the sides of the container). This way the wax will melt down evenly and you should get an even, clean burn without tunnelling or any wax left on the sides of the container.
Keeping you and your candle safe!
Never leave a burning candle unattended. Burn candles out of reach of children and pets. Always leave at least 10cm between burning candles. Do not burn your candle on or near anything that may catch fire. Only burn your candle on a level, heat resistant surface.
Never burn a candle for more than 4 hours at a time. Do not allow the flame to touch the glass. On the first burn, always burn for 3-4 hours to ensure an even melt pool. Ensure the wick is upright, above the wax and central before the wax sets. Always trim the wick to 5mm before lighting to avoid smoking and damage to the container. The candle container may become hot during use. Extinguish when 5mm of wax remains and do not relight until the candle has set.
