Air bubbles in candles are small pockets of air that become trapped within the wax while the candle is being made. These bubbles can appear as small pockets of space in the wax, or they can appear as small white spots on the surface of the candle.
They may appear to be harmless, however, they can have a significant impact on the burning, throw, and appearance of the candle. Air bubbles can cause uneven burning, causing the candle to the tunnel, which can make it difficult to light or extinguish the candle, also make the burn unevenly and create a wick that burns too quickly.
They can also affect the fragrance release, and hot and cold throw of the candle. Therefore it is important for candle makers to take steps to prevent air bubbles from forming in their candles.
How Air Bubbles Form?
Air bubbles in candles can form for a variety of reasons, including:
Pouring the wax at the wrong temperature: If the wax is too hot, it can cause air bubbles to form as it cools.
Pouring too quickly: If the wax is poured too quickly, it can cause air bubbles to form as it cools.
Cooling too quickly: If the wax is cooled too quickly, it can cause air bubbles to form as the wax contracts.
Humidity: High humidity can cause the wax to absorb moisture, which can then form bubbles as the candle cools.
Agitation: If wax is agitated during the pouring process, it can cause bubbles to form and become trapped in the wax.
Wax type: certain wax type tend to form more air bubbles than others, this is dependent on the wax’s properties.
Once the air bubbles are surrounded by wax, it can be difficult or impossible to remove them. In general, if the bubbles are small, they may not have much impact on the burning or appearance of the candle, but larger bubbles can cause issues. Some candle makers try to prevent air bubbles by poking the surface of the wax with a tool to release any bubbles that have formed. However, this is not a guarantee that all the bubbles will be removed.
Problems Caused by Air Bubbles
Air bubbles in candles can cause a number of problems, including:
Uneven Burning
Air bubbles can cause the candle to burn unevenly, which can produce a tunneling effect. This means that the candle will burn down the middle, leaving the outer wax untouched. This can make the candle difficult to light or extinguish, and can also make the candle burn for a shorter period of time.
Burning Too Quickly
Air bubbles can also cause the candle to burn too quickly. Because the wax around the wick is not solid, the wick can burn faster than it should, which can cause the wax to melt away from the wick and extinguish the flame.
Unattractive Appearance
Air bubbles can also make the candle look uneven or unattractive. They can appear as small white spots on the surface of the candle, which can be unsightly. This can affect the general appeal of the candle, making it less desirable to buyers.
Affecting Fragrance
Air bubbles can also affect the fragrance release of the candle, especially if they are larger and/or closer to the wick, this can also affect the throw of the fragrance both hot and cold.
These issues can cause problems for candle makers and consumers alike, and that’s why it’s important to take steps to prevent air bubbles from forming in candles.
Preventing Air Bubbles
Candle makers can take a number of steps to prevent air bubbles from forming in candles, including:
Pouring the Wax at the Correct Temperature
The wax should be heated to the correct pouring temperature, this varies depending on the type of wax used, too hot or too cold can cause bubbles to form.
Being Careful When Pouring
Candles makers should pour the wax slowly and carefully to minimize the formation of air bubbles.
Tap the Mold After Pouring
Tapping the mold gently after pouring can help release any trapped air bubbles.
Cooling Slowly and Evenly
Allowing the candle to cool slowly and evenly, avoiding rapid changes in temperature can prevent bubbles from forming.
Reduce Agitation
Reducing the agitation during the pouring process will minimize the amount of bubbles formed.
Using De-bubbling Agents
some candle makers use de-bubbling agents that are added to the wax mixture, which can help to reduce the formation of bubbles.
Using Tools
Some candle makers also use tools such as a needle or a skewer to poke the surface of the wax, to release any bubbles that have formed, this is not a guaranteed way of removing bubbles but it can help release some of them.
These steps can help to prevent the formation of air bubbles in candles, but it is important to note that bubbles may still form despite best efforts. It is essential for candle makers to do their own testing and experiments to find what works best for them in terms of preventing air bubbles in their candles.
How It Affects the Hot Throw, Cold Throw, and the General Appearance of the Candle.
Air bubbles can have a significant impact on the burning of a candle, the hot throw, cold throw and general appearance.
Uneven Burning
Air bubbles can cause the candle to burn unevenly, which can produce a tunneling effect. This means that the candle will burn down the middle, leaving the outer wax untouched. This can make the candle difficult to light or extinguish, and can also make the candle burn for a shorter period of time.
Burning Too Quickly
Air bubbles can also cause the candle to burn too quickly. Because the wax around the wick is not solid, the wick can burn faster than it should, which can cause the wax to melt away from the wick and extinguish the flame.
Affecting Fragrance
Air bubbles can also affect the fragrance release of the candle, especially if they are larger and/or closer to the wick. This can negatively affect the throw of the fragrance both hot and cold.
Unattractive Appearance
Air bubbles can also make the candle look uneven or unattractive. They can appear as small white spots on the surface of the candle, which can be unsightly. This can affect the general appeal of the candle, making it less desirable to buyers.
Overall, preventing air bubbles in candles is essential for achieving a quality burn and fragrance release, as well as having a visually pleasing candle. It is important for candle makers to test and experiment with different techniques to reduce the formation of bubbles in their candles, finding what works best for them.
