Glass can crack when there isn’t enough wax left to absorb the heat of the flame - this causes the vessel to overheat over time. To avoid this, stop burning your candle when 1cm of unmelted wax remains.

Cracking can also occur if the wicks shift and come into contact with the glass. This may happen if a candle burns longer than the recommended time, causing the wax pool to expand and the wicks to become unstable.

If your glass has cracked and you believe it wasn’t due to the above causes, please take photos and email us at orders@maisonblanche.com.au and we’ll be happy to look into it.
