Why Does Candle Tunneling Happen?

As candle enthusiasts, there's nothing more disappointing than lighting a beautiful candle, only to find that it burns unevenly, creating a dreaded tunnel. This frustrating phenomenon, known as candle tunneling, can reduce the lifespan and overall quality of your candle. But why does it happen? In this article, we will explore the reasons behind candle tunneling and provide some tips to prevent it from happening.

What is Candle Tunneling?

Before we delve into the reasons behind tunneling, let's define what it actually is. Candle tunneling occurs when a candle burns down the center, leaving a thick wall of wax around the edges of the container. This creates a hollow tunnel, making it difficult for the candle to burn properly.

Poor Wick Placement

One of the most common causes of candle tunneling is improper wick placement. When a wick is not centered or too close to the edge of the container, it can cause uneven heat distribution. As a result, the wax closest to the wick melts faster, while the outer edges remain solid. This leads to tunneling.

Poor Quality Wax

The type of wax used in a candle can also contribute to tunneling. Poor quality wax or a low-quality blend may have additives or impurities that affect the way it burns. These additives can cause uneven melting, resulting in tunneling. Investing in high-quality candles made from natural waxes can help minimize this issue.

Improper Burning Technique

Believe it or not, the way you burn your candle can also be a factor in tunneling. Burning a candle for too short of a time, especially during the first burn, can create a memory ring. This means that the wax will only melt up to the point where it initially melted. Subsequent burns will then follow this tunnel, causing uneven melting and tunneling. To avoid this, make sure to burn your candles for a few hours during the first use to allow the wax to melt evenly across the entire surface.

Large Diameter Candles

Candles with a larger diameter are more prone to tunneling. This is because a larger circumference requires more heat and time to melt the outer wax layers. If you find that your large candles are tunneling, try burning them for a longer period or consider using multiple wicks to evenly distribute the heat.

Drafts and Airflow

Another factor that can contribute to tunneling is drafts or excessive airflow around the candle. When there is too much airflow, the flame can become unstable and flicker or lean to one side. This uneven heat distribution can lead to tunneling. To prevent this, make sure to place your candles away from open windows, fans, or air conditioning vents.

Trimming the Wick

Not trimming the wick of your candle before each burn can also contribute to tunneling. A long wick can cause the flame to burn too hot, causing the wax to melt too quickly and unevenly. By trimming the wick to about ¼ inch before lighting, you can ensure a more controlled burn and minimize tunneling.

Containers that Trap Heat

The type of container in which your candle is housed can also affect tunneling. Containers that trap heat, such as those with narrow openings or deep bottoms, can prevent heat from dissipating properly. This causes the wax to melt unevenly, leading to tunneling. Opt for containers with wider openings and shallow bottoms to promote a more even burn.

Overly Scented Candles

While we love a strongly scented candle, using too much fragrance oil in the wax can contribute to tunneling. Excessive fragrance oil can affect the way the wax burns, causing it to tunnel instead of melting evenly. If you enjoy highly scented candles, make sure to follow the recommended fragrance load to avoid tunneling.

Preventing Candle Tunneling

Now that we understand the reasons behind tunneling, let's explore some tips to prevent it from occurring:

1. Trim the wick:

Before each burn, trim the wick to approximately ¼ inch. This will help create a steady and even burn.

2. Burn candles for a sufficient amount of time:

During the initial burn, allow the wax to melt evenly across the entire surface of the candle. This will prevent the development of a memory ring and promote a more even burn in subsequent uses.

3. Avoid drafts and excessive airflow:

Ensure that your candles are placed in a draft-free area to prevent flickering and uneven heat distribution.

4. Select the right container:

Choose containers with wider openings and shallow bottoms to encourage even wax melting and minimize tunneling.

5. Use high-quality candles:

Invest in candles made from natural waxes, free from additives and impurities that can contribute to tunneling.

6. Follow fragrance load guidelines:

If you use scented candles, make sure to adhere to the recommended fragrance load to ensure optimal burning and avoid tunneling.

The Perfect Candle Burning Experience

Candle tunneling can be a frustrating experience, but by understanding its causes and implementing preventive measures, you can enjoy a perfect candle burning experience every time. Remember to trim the wick, burn your candles for a sufficient amount of time, avoid drafts, choose the right container, and use high-quality candles. By following these tips, you'll create an inviting atmosphere with a beautifully burning candle that enhances any space.
