First Burn Give your candle enough burning time to develop a melted wax pool that goes all the way to the edge of the container on the first use - this can take up to three hours. If the wick won't stay lit If the wick doesn't stay lit or light up is probably because the wick needs to be trimmed and clean of charred material. Trim the wick, and give the candle a good long burn until the wax is melted to the edge of the jar.
