Maintaining a safe and effective wick height will ensure the candle burns just as it should. Always trim your candle wick to 5mm in height before each burn (don't worry, we've done this for you, ready for the first burn). Trimming your wick will also ensure that the candle does not burn too hot/too quickly, allowing for a safe, clean burn all the way down. Our wicks are also engineered to have a small amount of wax left at the bottom of the candle; this is so you can't burn the candle when there's not enough wax left, preventing the vessel from becoming too hot and breaking.
