Candle tunneling is a common issue that can be frustrating, especially when you’ve invested in a high-quality candle. It occurs when a candle burns down the center, leaving a ring of unburned wax around the edges. This not only wastes wax but also shortens the overall burn time of the candle.

Here’s a closer look at why candle tunneling happens and how you can prevent or fix it.

What Causes Candle Tunneling?

Candle tunneling usually happens when the candle doesn’t burn long enough for the wax to melt evenly across the entire surface. Here are some common reasons:

        •       First Burn Mistake: When you first light a candle, it’s essential to let it burn long enough for the top layer of wax to melt completely, reaching the edges of the container. If you extinguish the flame too early, it sets the stage for tunneling.

        •       Wick Issues: Using the wrong wick size can also cause tunneling. A wick that’s too small won’t produce enough heat to melt the wax evenly across the surface.

        •       Environmental Factors: Drafts or uneven surfaces can cause candles to burn unevenly, promoting tunneling.

How to Prevent Candle Tunneling

        1.      First Burn is Key: Always allow your candle to burn for 2-4 hours on its first burn or until the wax pool reaches the edges of the container. This creates an even “memory burn” for future uses.

        2.      Trim Your Wick: Regularly trim the wick to about 1/4 inch to ensure an even burn and to prevent issues like smoking or uneven melting.

        3.      Keep Candles Away from Drafts: Ensure your candle is in a location free from drafts and uneven surfaces to maintain a steady and even burn.

How to Fix Candle Tunneling

If your candle has already tunneled, don’t worry! Here are a few ways to fix it:

        •       Aluminum Foil Method: Wrap a piece of aluminum foil around the top of the candle, leaving an opening at the center for the flame. The foil will trap heat, helping to melt the unburned wax on the edges. After about 30 minutes, remove the foil, and your candle should have an even wax pool.

        •       Use a Heat Gun: For extreme tunneling, a heat gun can melt the top layer of wax evenly, resetting the candle’s surface.

By following these simple steps, you can extend the life of your candle and enjoy a perfect burn every time. Tunneling may seem like a small issue, but resolving it will make sure you get the most out of your candle.
