The most common reason for a candle to tunnel is not burning long enough the first time it was lit. The first light of a candle is very important in ensuring a clean and even burn for every burn afterward.
When you receive your new Antique Candle Co.™ candle, let it burn long enough to allow the melted wax on the surface to reach the edge of the jar. This may take 2-4 hours depending on the size of your candle.
If the candle does not burn long enough in a large room, you may not be able to smell the wonderful aromas as strongly. After you burn it, your candle may have a bumpy or rough surface. 100% soy wax naturally solidifies this way, and does not effect the quality of the candle in any way.
