What is a burn pool and candle memory?
When you burn a candle the melted wax begins to form a pool. This is referred to as the burn pool. This burn pool creates a future burn pattern for the candle (or “memory”). Therefore, if a candle is not allowed to pool to the edges, the next time you light it, it will most likely not burn past that point and you may end up with a tunnel effect. If you are burning cheap candles, this is likely to happen anyway.
