My candle does not burn evenly. Is this normal?

To ensure your candle burns evenly, it is essential, during the first use, to let it burn for 2 to 3 hours so that all the wax melts on the surface. Finally, it is important to avoid draft and to trim the wick to 3 to 5 mm in height as well as to recenter it after each use (while the wax is still liquid).
