How To Keep Candle From Tunneling


What is Candle Tunneling?

Candle tunneling refers to a common problem encountered when burning candles. It occurs when the candle burns down the center, leaving an untouched ring of wax around the edges. This creates a tunnel-like formation, making it difficult for the candle to burn evenly and efficiently. Candle tunneling not only reduces the lifespan of the candle but also diminishes its aesthetic appeal.

When you light a candle, it is important for the wax to melt evenly across the surface. This allows for a full pool of melted wax, ensuring a clean and consistent burn. However, if the candle is not burned properly, tunneling can occur. The melted wax from the initial burn sets a memory ring, and subsequent burns will only reach the edge of this ring, creating a tunneling effect.

Tunneling can happen for various reasons, including the type of wax used, the wick size, and even the burning techniques utilized. It is important to understand the causes of tunneling in order to prevent it from happening and prolong the life of your candles.

Why does Candle Tunneling Happen?

Candle tunneling can occur due to several reasons, and understanding these causes is crucial in preventing this issue from happening. Here are some common factors that contribute to candle tunneling:

  • Improper Wick Placement: When the wick is placed too close to the edge of the container, it creates an uneven heat distribution. This causes the wax to melt faster along the side where the wick is located, leading to tunneling.
  • Poor Quality or Incorrectly Sized Wick: Using a wick that is too small or low-quality can result in inadequate heat and flame production. This can prevent the candle from reaching a full melt pool and cause tunneling.
  • Inadequate Burning Time: Burning a candle for too short of a time period can contribute to tunneling. It is essential to allow the candle to burn for a sufficient amount of time until the entire surface has melted to avoid the memory ring formation.
  • Drafty Environment: Placing a candle in a drafty area can disrupt the flame’s stability and affect the even burn of the wax. Inconsistent heat distribution can lead to tunneling.
  • Poor Candle Quality or Formulation: Some candles are more prone to tunneling due to their wax formulation or poor manufacturing techniques. Lower-quality candles may not have the ideal composition to promote an even burn.

Combining any of these factors can increase the likelihood of tunneling. To prevent this issue, it is essential to choose quality candles, properly place the wick, and ensure optimal burning conditions.

Choosing the Right Candle

When it comes to preventing tunneling, selecting the right candle is essential. Here are some important factors to consider when choosing a candle:

  • Wax Type: Opt for candles made from high-quality wax, such as soy wax or beeswax. These types of wax have a lower melting point, allowing for a more even and consistent burn.
  • Container Size: Consider the size of the candle container. Smaller containers tend to promote tunneling as the heat is concentrated in one area. Choose candles with wider containers that allow for a larger melt pool.
  • Wick Size: Ensure that the candle has the appropriate wick size for optimal burning. A wick that is too small may not generate enough heat to melt the wax evenly, leading to tunneling.
  • Quality: Invest in candles from reputable brands known for their quality craftsmanship. High-quality candles are more likely to have consistent wax formulation and wick placement, reducing the chances of tunneling.
  • Fragrance Level: Fragrance oils can impact the candle’s burn. Candles with a high concentration of fragrance oil may burn hotter, increasing the likelihood of tunneling. Opt for candles with a balanced fragrance-to-wax ratio.

By considering these factors, you can choose candles that are less prone to tunneling, ensuring a longer-lasting and more enjoyable burn.

Prepping Your Candle

Properly preparing your candle before lighting it can play a significant role in preventing tunneling. Follow these steps to ensure an even burn:

  1. Trim the Wick: Before lighting the candle, trim the wick to approximately a quarter of an inch. This helps to prevent excessive flickering and uneven burning.
  2. Remove Debris: Clear away any debris, such as dust or burnt wick, from the surface of the candle. This ensures a clean burn and reduces the chances of tunneling.
  3. Center the Wick: Check to ensure that the wick is centered in the middle of the candle. If it is off-center, use a wick centering tool or gently adjust it to the correct position.
  4. Level the Wax: If the wax surface is uneven, gently melt the surface using a hairdryer on low heat or a candle warmer. This helps to create an even starting point for the candle to burn from.
  5. Pre-Burn Technique: Before the first burn, allow the candle to burn for a sufficient amount of time to create a full melt pool that reaches the edges of the container. This helps to prevent the formation of a memory ring and promotes an even burn.

By following these prepping steps, you can ensure that your candle is ready for a clean and even burn, reducing the chances of tunneling and enhancing its overall performance.

Proper Lighting Techniques

Lighting a candle correctly is essential for promoting an even burn and preventing tunneling. Follow these tips to ensure proper lighting:

  1. Use a Long-Handled Lighter or Matches: When lighting a candle, it’s best to use a long-handled lighter or matches to reach the wick without accidentally extinguishing the flame.
  2. Avoid Blowing Out the Flame: Instead of blowing out the flame, use a snuffer or gently dip the wick into the melted wax and then straighten it back up. This helps to prevent the wick from being disturbed and promotes an even burn.
  3. Burn for an Adequate Length of Time: Allow the candle to burn for at least one hour or until the melt pool reaches the edge of the container. This ensures that the memory ring is not formed and helps to prevent tunneling.
  4. Avoid Drafty Areas: Place the candle in an area where it won’t be exposed to drafts or strong air currents. Drafts can cause uneven burning and lead to tunneling.
  5. Monitor the Burn: Pay attention to the candle while it is lit. Make sure the flame is stable and the melt pool is even. If you notice any signs of tunneling, correct it immediately by carefully repositioning the wick.
