When a candle makes popping noises, it can indicate that the candle is burning improperly or that there are impurities in the wax. When a candle burns, it can create small air pockets within the wax. As the flame burns down to the bottom of the pocket, it can cause a popping sound as the air escapes. This is a normal occurrence and does not necessarily mean the candle is dangerous.
However, if the popping sound is accompanied by a large flame, excessive smoke, or a strong odor, it could be an indication that the candle is burning improperly. Additionally, if the candle has impurities such as water or air bubbles in the wax, it can cause it to pop and potentially splatter hot wax, which could be dangerous.
Reasons Why Candle Makes Popping Noises
Air Bubbles
One of the most common causes of candle popping noises is air bubbles trapped within the wax. As the candle burns, the heat causes the air bubbles to expand, according to Harvard University, which can create a popping or crackling sound.
This is especially common in candles poured into containers, as the wax can trap air bubbles between the candle and the container. To avoid this issue, it’s important to properly mix the wax and pour it slowly to prevent air bubbles from forming.
Moisture
Another common culprit of popping noises in candles is moisture. If the wick or wax is damp, it can create a hissing or popping sound as the moisture is burned off. This can be caused by storing candles in a damp environment or accidentally spilling water on the candle. To prevent this issue, it’s important to store candles in a cool, dry location and to keep them away from any sources of moisture.
Impurities in the Wax
Impurities in the wax refer to any foreign material introduced into the candle wax during the manufacturing process or while the candle is being made. Some common impurities include air bubbles, water, dust, or other debris. These impurities can affect the quality of the candle and cause it to burn improperly or create popping noises.
Wick Size and Type
The size and type of wick used in a candle can also contribute to popping noises. If the wick is too thick or too long, it can create a larger flame that burns through the wax too quickly. This can cause air pockets to form within the wax, which can lead to popping noises.
Additionally, some wick materials, such as cotton or fiber, can create a crackling sound as they burn. To prevent this issue, it’s important to choose the right wick size and material for the type of wax being used.
The Danger of Popping Noises in Candles
Popping noises in candles are not necessarily dangerous, but they can indicate that the candle is burning improperly or has impurities in the wax.
When a candle burns, it can create small air pockets within the wax. As the flame burns down to the bottom of the pocket, it can cause a popping sound as the air escapes. This is a normal occurrence and does not necessarily mean the candle is dangerous.
However, if the popping sound is accompanied by a large flame, excessive smoke, or a strong odor, it could be an indication that the candle is burning improperly. Additionally, if the candle has impurities such as water or air bubbles in the wax, it can cause it to pop and potentially splatter hot wax, which could be dangerous.
To prevent popping noises and ensure safe burning, it is important to always trim the wick to ¼ inch before lighting the candle and keep it away from drafts or other sources of airflow. It is also important to never leave a burning candle unattended and to keep it away from flammable materials.
Tips to Prevent Popping Noises in Candles
Candles are a great way to create ambiance and add warmth to any room. However, some candles’ popping and crackling sounds can be annoying and distracting. Here are some tips to prevent your candles from making popping noises:
Trimming the Wick
An untrimmed wick is one of the most common causes of candle popping noises. If the wick is too long, it can create a larger flame, which can cause the wax to melt too quickly and produce popping sounds. To prevent this, trim the wick to 1/4 inch before lighting the candle. You can use scissors or a wick trimmer to do this.
Choosing the Right Candle Size
The size of the candle can also affect whether or not it makes popping noises. For example, if the candle is too small for its container, it can cause the wax to heat unevenly and create popping sounds. To prevent this, choose the right size candle for the container. You can also choose candles that are specifically designed for the container you have.
Storing Candles Properly
Based on experience, if the candle is exposed to moisture, it can create air pockets in the wax, which can cause popping sounds. To prevent this, store your candles in a cool, dry place. You can keep them in a container or jar to protect them from impurities and moisture.
