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 your candle stays lit, give it a good long burn until all the wax is melted to the edge of the jar, and you've effectively "reset" the memory of the wax. If your candle doesn't stay lit because it is "drowning" in a wax pool, try using a paper towel or napkin to soak up some of the excess wax.
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. You can use a napkin and your fingers to gently break off the burnt parts of the wick and remove a little of the wax from around the wick.
Taper Burning Tips
Place the candle in a secure holder. The candle is made to burn down into itself consuming all of the wax when burned properly.
Keep candles away from open windows, fans, or airflow of any kind. Place your hand behind the flame when blowing out.
The approximate burn time is one hour per inch.
