1. Trim The Wick
For optimal burning, trim wicks to a 6mm ( ¼” )before each light to avoid smoking and overheating with your scissor or wick trimmer. Once the flame is extinguished make sure the wick is upright and centred.
2. First Burn
As with all candles, the first burn is the most important. To begin, let the wax melt all the way across. Once your candle's lit, don't blow it out until the top layer of wax has melted the entire top layer of wax to avoid tunnelling.
3. Each Burn
Candles should not be burned for more than four hours at a time. It is recommended that after burning for four hours, candles be extinguished, allowed to cool for two hours, and trimmed before relighting. Never leave burning candles unattended.
4. Fix From Tunnelling
You can get rid of that unsightly tunnel by folding a piece of aluminium foil in half, wrapping it around the candle, and then folding it up over the flame like a tent (leaving a hole for it to get oxygen). Keep the foil on for about 30 minutes, and all of that built-up wax should be melted off the sides.
5. Putting Candle Out
Use a snuffer or a dipper to put out your candle. It's safer than blowing them out, which can send sparks and hot wax flying and the wick may continue to glow and emit smoke. Double-check your candle is extinguished.
6. Leave The Last Bit
Don't burn the candle when the wick is shorter than 6mm ( ¼” ) in case of the candle jar crack because of overheat.
7. Reuse Your Jar
After finishing the candle, just wash out the residue with running water and detergent in order to reuse the jar whatever you want for a cleaner future.
