Candle Safety
Never leave lit candles unattended
Burn candles away from pets and children
Burn your candle in a well ventilated place but away from draughts
Choose a space for your candle away from objects that can catch fire
Do not burn for more than 3-4 hours at a time. This can cause the wick to move from its central position
Do not burn the last 10mm of wax at the bottom of the candle

Candle Advice
Keep candle wicks trimmed to 4 - 6mm to avoid the wick ‘mushrooming’. This will give a cleaner burn and prevent smokey burn marks forming on the candle container.
Use a sharp wick trimmer or scissors to trim the wick to avoid fraying.
Make sure you remove any trimmings or other debris from the surface of the candle.
When you first light your candle do not extinguish it until the wax has melted across the top of the candle. This will prevent tunnelling, where the wick sinks in the centre of the candle becoming difficult to light. Tunnelling leaves wasteful unmelted wax around the edge of the candle container.
Keep your candle away from flowing air. Moving air can contribute to black smokey stains on the container edges.
Troubleshooting

If your flame burns too weak the wick has been trimmed too short. Extinguish the flame and pour off some of the excess liquid wax into a safe container then relight
If your flame burns too high and flickers the wick is too long or the candle is in a draught. Extinguish candle and trim wick when cool enough to do so safely.
If the wick moves from the centre of the candle reposition after extinguishing the flame. The candle container could overheat and crack if the wick is not repositioned.
To prevent smoke emitting from the wick when it is extinguished dip the wick into the liquid wax rather than blowing it out, alternatively use a snuffer.
