As the owner of Calen, a shop specializing in non-toxic, eco-friendly 100% natural soy candles, body care, and fragrances, I've often encountered questions from customers about a common issue known as "candle tunneling." In this blog post, I'll explain what candle tunneling is, why it happens, and provide some tips to help you fix it.
What is Candle Tunneling?
Candle tunneling occurs when a candle burns down the center, creating a deep, narrow well or "tunnel" in the wax, while the outer edges of the candle remain solid and unburned. This can be frustrating for candle lovers, as it can lead to an uneven, inefficient burn and a shorter lifespan for the candle.
Why Does Candle Tunneling Happen?
There are a few common reasons why candle tunneling occurs:
-
Wick Placement: If the wick is not centered properly in the candle, it can cause the flame to burn unevenly, leading to tunneling.
-
Wax Composition: Some wax types, such as paraffin, are more prone to tunneling than others, like soy wax. The composition and quality of the wax can affect how it melts and burns.
-
Candle Container: The size and shape of the candle container can also play a role. Taller, narrower containers are more susceptible to tunneling than wider, shallower ones.
-
Burning Time: If a candle is burned for too long in a single session, it can also contribute to tunneling. The wax around the wick melts faster than the outer edges, creating the tunnel effect.
How to Fix Candle Tunneling
Fortunately, there are a few steps you can take to prevent or fix candle tunneling:
-
Trim the Wick: Before lighting your candle, make sure to trim the wick to about 1/4 inch. This helps ensure an even, consistent burn.
-
Allow the Wax to Melt Fully: When you first light your candle, let it burn until the entire surface of the wax has melted. This helps establish an even, level burn pool.
-
Avoid Burning for Too Long: Limit your candle-burning sessions to 2-4 hours at a time to prevent the wax from tunneling.
-
Use a Wick Dipper: If you notice tunneling starting to occur, use a wick dipper or other tool to gently push the wick back into the center of the candle.
-
Consider Soy Wax Candles: As mentioned earlier, soy wax is less prone to tunneling than paraffin. Switching to soy-based candles can help prevent this issue.
By following these tips, you can help ensure your candles burn evenly and efficiently, maximizing their lifespan and enjoyment. If you have any other questions about candle care or our products at Calen, don't hesitate to reach out. Happy candle burning!
