There’s nothing quite as relaxing as lighting a candle and enjoying its flickering glow. However, have you ever noticed that sometimes your candles develop a sinkhole in the middle as they burn? This can be both frustrating and disappointing, especially if you’ve invested in high-quality candles. But why does this happen?

The sinking of candles in the middle is a common issue that many candle lovers experience. It occurs when the wax in the center of the candle melts faster than the wax at the edges, causing a depression or sinkhole to form. Not only does this affect the appearance of the candle, but it can also impact its burn time and fragrance throw.

In this article, we will explore the various causes of sinking candles and how you can prevent this issue from occurring. By understanding the underlying reasons, you’ll be able to enjoy aesthetically pleasing and long-lasting candles every time you light them.

Causes of sinking candles

There are several factors that can contribute to the sinking of candles in the middle. Let’s delve into each one to gain a better understanding:

1. Inadequate wick size: The size of the wick plays a crucial role in the even burning of a candle. If the wick is too small for the diameter of the candle, it may not generate enough heat to melt the wax evenly. As a result, the center of the candle will burn at a slower rate, leading to the formation of a sinkhole.
2. Poor quality wax: The quality of the wax used in a candle can also affect how it burns. Cheaper or lower quality wax may contain additives or impurities that hinder its ability to burn evenly. In such cases, the candle is more likely to sink in the middle as the inferior wax melts at an uneven pace.
3. Uneven cooling: After a candle has been burned, it needs to cool down evenly to maintain its shape. If a candle is not given enough time to cool properly or is exposed to sudden temperature changes, the center may collapse inward. This can happen if you extinguish the candle before it has completely formed a full melt pool or if you move it while the wax is still hot.
4. Drafts and air circulation: Candles placed in drafty areas or areas with strong air circulation can experience uneven burning. When a draft disturbs the flame, it can create turbulence in the melt pool, causing the center of the candle to burn slower and create a sinkhole.
5. Overheating: It’s essential to follow the recommended burn time guidelines for each candle. Overheating a candle by burning it for too long can cause the center to soften and sink. Additionally, exposure to direct sunlight or high temperatures can also lead to the melting of the wax in the middle, resulting in a sinkhole.

Understanding these causes will help you identify the potential reasons behind your sinking candles. By addressing these factors, you can take proactive steps to prevent your candles from sinking in the future.

Inadequate wick size

The size of the wick used in a candle plays a crucial role in its performance. When the wick is too small for the diameter of the candle, it may not generate enough heat to melt the wax evenly. As a result, the center of the candle burns at a slower rate compared to the outer edges, leading to the formation of a sinkhole.

Choosing the correct wick size depends on several factors, including the type of wax used, the diameter of the candle, and the desired burn time. If you’re experiencing sinking candles, it may be worth considering whether the wick size is appropriate for your candles.

To determine the correct wick size, you can refer to the wick size chart provided by candle-making suppliers. This chart suggests the appropriate wick size based on the diameter of your candle. For instance, a larger candle with a wider diameter will require a thicker wick to ensure proper heat distribution and even melting.

If you’re making your own candles, it’s important to experiment with different wick sizes to find the optimal one for your specific wax and container. Keep in mind that environmental factors, such as drafts or air circulation, can also affect the burn rate of the candle, so it’s essential to consider these factors when choosing the wick size.

By selecting the right wick size, you can ensure that your candles burn evenly and prevent the formation of sinkholes. A properly sized wick allows for a consistent melt pool to form, ensuring that all the wax is utilized and avoiding any wasted wax in the center of the candle.

Furthermore, using the correct wick size not only helps in preventing sinking candles but also promotes other desirable qualities such as a steady flame, maximum fragrance throw, and an extended burn time.

Uneven cooling

Proper cooling is an important aspect of candle making and burn quality. When a candle is not allowed to cool evenly, it can lead to the formation of sinkholes in the center.

After you have extinguished a candle, it’s crucial to give it enough time to cool down completely before relighting or moving it. If a candle is moved or disturbed while the wax is still hot and malleable, it can result in an uneven surface and cause the center to collapse inward.

To ensure even cooling, it’s recommended to follow these guidelines:

1. Allow for a full melt pool: When you light a candle, it’s important to let it burn until a full melt pool forms. A melt pool refers to the melted wax that reaches the edges of the container. This helps to ensure an even burn and prevents the formation of sinkholes. If a candle is not allowed to create a full melt pool during the initial burn, it may result in uneven cooling and sinking in the center.
2. Avoid extinguishing the candle too soon: Extinguishing a candle before a full melt pool has formed can also contribute to uneven cooling. If you blow out the flame prematurely, the wax may not have had enough time to completely melt and distribute heat evenly. This can lead to a sinkhole forming in the center of the candle.
3. Avoid moving a hot candle: It’s essential to let the candle cool down completely before moving it. Moving a hot candle can disrupt the cooling process and result in an uneven surface. If you need to change the location of a candle, ensure that the wax has solidified and is no longer malleable.
4. Avoid placing candles in a drafty area: Air circulation around a burning candle can affect how evenly it burns and cools. Placing candles in drafty areas or areas with strong air currents can disrupt the heat distribution and result in uneven cooling. This can cause sinkholes to develop in the center of the candle.

By implementing these cooling techniques, you can help prevent the formation of sinkholes and ensure that your candles maintain a smooth and even surface. Proper cooling not only enhances the visual appeal of your candles but also contributes to their longevity and burn quality.
