Our wooden wicks should burn down with the candle but can be easily trimmed with nail clippers if the flame gets too high, it is recommended to keep the wick at 5mm above the wax for optimal burn.
In the unlikely event that the glass should crack, as can happen to all glass when heated, please extinguish the flame and contact us to arrange return of the candle for a free of charge replacement.
As with all candles it is important not to leave them burning unattended and to only light on a level, fire-resistant surface.
