Testing Your Wick

Before using your wick for a soy candle, it is important to do a test to ensure proper performance. This will help you to adjust the wick size and shape, if needed, before you make the entire candle. To properly test your wick, all you have to do is:

  • Fill a container with soy wax and let it cool.
  • Position the wick at the centre of the container. Make sure to keep it straight and secure it in place with a skewer.
  • Light the candle and observe the flame size and shape.
  • If the wick doesn’t burn with the desired flame, trim the wick and start the test again.

Common Wick Problems

There are several problems that may arise when choosing the wrong wick for soy candles.

  • Mushrooming: This usually happens when the wick is too large, causing the flame to become overly large and releasing too much carbon dioxide.
  • Tunneling: This happens when the wick is too small for the candle and causes the wax not to completely burn, creating “tunnels” in the candle.
  • Smoke or Soot: This is usually caused by an incorrect wick or when the flame is too far away from the wick.


Soy candles are gaining more popularity with each passing day, especially as people become more aware of environmental concerns and the health hazards of burning traditional candles. As a result, it is important to select the right wick for soy candles to ensure a clean and optimum burn. The best wicks for soy candles include cotton and bamboo, while selecting the right size is determined by the container size, wax type, and fragrance load. If the wick is the right size and material, then the best way to test it is to fill a container with wax, position it carefully and light the wick. This will help to ensure that you don’t experience any common wick problems.
