How To Fix Candle Sinkholes

Common Causes of Candle Sinkholes

Candle sinkholes are a common issue that many candle lovers encounter. These unsightly depressions can occur in the center or sides of a candle, disrupting its overall appearance and burning performance. Understanding the causes of candle sinkholes can help you prevent and fix them effectively. Here are some common factors that contribute to candle sinkholes:

Inadequate Cooling Time: When candles are not given sufficient time to cool and solidify after being poured, it can lead to sinkholes. Rushing the cooling process may result in the exterior of the candle hardening while the interior remains molten, causing the wax to collapse and form sinkholes.
Poor Wax Quality: Using low-quality or inferior wax can also contribute to candle sinkholes. Wax that contains impurities or that is not formulated for candles may shrink or develop sinkholes during the cooling process.
Incorrect Wick Size: Choosing the wrong wick size for your candle can affect its burn performance and lead to sinkholes. A wick that is too small may not generate enough heat to melt the surrounding wax evenly, causing sinkholes to form.
Uneven Pouring Temperature: Pouring the wax at inconsistent temperatures can result in sinkholes. When the initial pour is too hot, it can cause the center of the candle to collapse as it cools. Conversely, pouring wax that is too cool can cause sinkholes to form near the sides of the candle.
Presence of Air Bubbles: A lack of thorough stirring or the presence of air bubbles in the wax can contribute to sinkholes. When the wax solidifies around trapped air pockets, it can create empty spaces and cause sinkholes to develop.

By being aware of these common causes, you can take proactive measures to prevent the formation of sinkholes in your candles. In the next section, we will explore some precautions you can take to minimize the occurrence of candle sinkholes.
