Issue: ‘Tunnelling’, whereby the candle is left with a hole down the centre, reducing the amount of light from the flame and increasing the wax lost.
Reason: The candle has not been left to burn for long enough.
Tip: Allowing the entire top layer of the candle to melt to the sides of the jar on first use creates a ‘burn memory’. Doing this means subsequent uses should follow the same pattern, avoiding the tunnelling effect. Pooling time for our small jars is approximately 45mins and 90 mins for the large jars.
Result: Maximum burn time using all of the wax, cleaner glass container and more light from the flame!
