The Art
Of Burning


To fully enjoy your candle and keep its aesthetic intact, there is a burning ritual to carry out.

In order to guarantee optimal use, The CANDUAL Team recommends that you follow the safety instructions and always keep your candle under surveillance.

1. Trim the wicks regularly. They should not exceed 0,5cm (1/4 inch).

2. Wait until the whole surface becomes liquid before putting out your candle.

3. NEVER exceed one hour of burning once the whole surface is liquid.

4. NEVER burn the last 1cm (1/2 inch) of wax to avoid flames burning against the glass.
A flame burning against the glass may cause the glass to break !

5. Before the wax becomes totally solid, reposition the wicks vertically to their initial place.
Regularly clean the inside of the candle to avoid the appearance of soot.

6. Most of our candles are REVERSIBLE, use only one side the same days…
Or wait at least 3H before returning your CANDUAL.

If you want to take full advantage of your 2nd fragrance, it is better to wait until the next day before returning your CANDUAL.

Safety A Priority !
