What is Tunneling
Tunneling is a common issue that can occur when making candles. It refers to the phenomenon where a candle burns straight down in the center, leaving unused wax on the sides of the container. This creates a tunnel-like appearance and reduces the overall burn time of the candle. Understanding what causes tunneling and how to prevent it is essential for achieving beautifully burning candles.
Tunneling Process and Causes
Tunneling occurs when a candle does not achieve a full melt pool during each burn. A full melt pool means that the entire surface area of the candle has liquefied, from edge to edge, creating an even layer of molten wax. When tunneling happens, only a small portion of the wax around the wick melts, creating a tunnel-shaped cavity while leaving unused wax along the sides.
Several factors contribute to tunneling in candles. One common cause is using an improper wick size. If the wick is too small for the diameter of the candle or if it doesn’t produce enough heat to create a full melt pool, tunneling can occur. Another factor is using wax that has poor melt characteristics or contains additives that inhibit proper burning.
The good news is that there are several steps you can take to prevent tunneling when making candles.
Firstly, choosing the right wax is crucial. Look for container waxes specifically designed for minimal or no tunneling issues. These waxes often have additives that help promote an even burn and prevent tunneling.
Secondly, selecting an appropriate wick size is important for preventing tunneling. It’s recommended to use a larger size wick that matches your candle’s diameter to ensure sufficient heat generation and encourage a full melt pool.
Lastly, maintaining your candles properly plays a significant role in avoiding tunneling. Trim your wick before each use to about ¼ inch in length to avoid excessive soot and ensure a steady flame. Additionally, make sure the wick is centered in the container to allow for an even burn.
By addressing these factors and following proper candle-making techniques, you can effectively prevent tunneling and enjoy beautifully burning candles that provide optimal brightness and longevity.
Common Causes of Tunneling
Tunneling is a common problem that candle makers often face. It refers to the uneven burning of a candle, where a hole forms down the center and wax accumulates around the edges, thus wasting valuable wax and reducing the burn time of the candle. Understanding the common causes of tunneling is crucial in order to prevent this issue and create beautiful, long-lasting candles.
One of the main causes of tunneling is using an improper wick size. If the wick is too small for the diameter of the candle, it will not generate enough heat to melt the wax evenly across the entire surface area. As a result, only a small portion in the center will melt while leaving untouched wax along the sides. This leads to tunneling.
The type and quality of wax used can also contribute to tunneling. Different waxes have different melting temperatures and densities, which can affect how evenly they burn. It is important to choose a wax that is specifically formulated for container candles and has a lower melting point.
Furthermore, improper candle maintenance can also cause tunneling. If the wick is not trimmed properly or not centered in the container, it can lead to uneven burning and tunnel formation. Trimming the wick to about 1/4 inch before each use helps ensure that it burns at an optimal rate.

Frequently Asked Questions
How do you stop candles from tunneling?
To stop candles from tunneling, there are a few steps you can take. Firstly, it’s important to always trim the wick of your candle before lighting it. This helps to maintain an even flame and prevents excessive heat build-up, which can contribute to tunneling.
Additionally, when you initially light your candle for the first time, allow it to burn long enough for the entire surface of the wax to melt evenly. This forms what is called a “memory ring,” preventing future tunneling. If you continue to experience tunneling, try switching to a larger wick size or using a wick trimmer tool to slightly expose more of the wick.
Why are my candles tunneling after pouring?
Candles can sometimes experience tunneling after pouring due to various factors. Tunneling occurs when the outer edges of the wax do not fully melt and instead form a tunnel-like cavity in the center of the candle while burning. One common reason for this is burning the candle for too short of a time during its initial lighting.
If the wax is not given enough time to melt across the entire diameter on its first burn, subsequent burns may result in tunneling. Another factor could be using a wick that is too small or placing multiple candles too close together, causing insufficient heat distribution and resulting in tunneling.
Does candle warmer fix tunneling?
Candle warmers are designed primarily for fragrance purposes rather than fixing tunneling issues in candles. While candle warmers can help release scented oils and fragrance from candles without actually burning them, they don’t necessarily fix or prevent tunneling problems that may exist in certain candle designs or formulations.
The heat provided by candle warmers may be different from that of an open flame, so relying solely on candle warmers might not address specific issues related to uneven melting or improper wick sizes that contribute to tunneling. It’s still important to consider proper care techniques such as trimming wicks and allowing sufficient burn times when seeking to prevent tunneling in candles.
