Candle Care
To avoid tunnelling, give your candle plenty of burn time to allow it to melt and reach the edge of the vessel. To light the wood wick, light from edge to edge to ensure even burn. Wood wick may need a second lighting straight after the initial one to imbed memory.
Sit candle on a flat surface away from anything above that could overheat or catch alight. Trim your wick before each use after initial light.
