The wax around the wick is depressed, and requires a second fill.
Erin Huffstetler
Sometimes you'll end up with a depressed area around the wick of the candle. This is a common occurrence and an easy problem to remedy. Just melt some more wax, and pour it into the void. Then, once the new wax has hardened, simply trim the wick down to size; and your candle is ready for use!
