In candle-making, a 'wet spot' refers to an air pocket that occurs as the wax cools down, causing it to pull away from the container's edge. This results in an uneven finish that some candle makers find displeasing. While wet spots are considered a cosmetic issue that does not impact a candle's performance, extreme cases can cause the candle to fall out of its container. They are caused primarily by temperature changes, with wax expanding when heated and contracting as it cools. Since it is challenging to control temperature fluctuations, especially during transportation and storage, wet spots are common and difficult to avoid entirely. Candle makers can mitigate wet spots by using specific wax types, adjusting pouring temperatures, and selecting different container colours. Ultimately, while wet spots may concern makers, many consumers prioritize scent and even view handcrafted irregularities as desirable.

Causes of wet spots in candles
In candle-making, "wet spots" refer to patches that appear on the sides of a candle. They are caused by multiple factors, but the main cause is temperature change. When the wax melts, it turns into a liquid, and once it is poured into a jar and cools down, it starts to shrink and contract. This contraction separates the wax from the jar, creating a wet spot. These spots may not appear immediately and can show up after a few weeks, depending on the temperature surrounding the candle.
Candles typically experience small temperature changes throughout their lifecycle. Whenever there is a temperature change, the likelihood of candle wax pulling away from the jar sides increases. While the most noticeable volume change occurs right after pouring the candle, you may also observe the pulling during curing, shipping, or storage.
The adhesion problems that cause wet spots are unavoidable due to environmental changes. Moisture in the container can also cause adhesion issues, impacting the candle's appearance. To mitigate these issues, candle-makers can clean containers with dish soap, white vinegar, and hot water before pouring wax. Ensuring the jar is completely dry before pouring wax is crucial, as moisture can negatively affect the candle's appearance.
While wet spots can be visually unappealing, they do not affect the candle's performance or burnability. They are purely aesthetic issues, commonly found even in big brands and retail stores. To cover wet spots, you can place a label or use a coloured jar to hide the spot from view.

How to prevent wet spots
Wet spots are caused by temperature changes during the candle's lifecycle, which increase the likelihood of candle wax pulling away from the jar's sides. While they are only cosmetic and do not impact performance, if you are looking to prevent wet spots, here are some tips:
Firstly, clean your containers ahead of time using dish soap and/or white vinegar, followed by a hot water scrub. Ensure the jar is completely dry before pouring in any wax. You can do this by resting the jar upside down on a towel or using a heat gun to accelerate the drying process. Moisture in the container can negatively impact the appearance of your candle.
Next, consider pouring your wax at a cooler temperature into a pre-heated container. This reduces the temperature difference between the wax and the jar. If the sides are too cool, differential cooling will occur, causing the sides to cool faster than the top or middle, leading to poor adhesion. Aim for the temperature of the room, and if it is a bit colder or hotter, adjust the pouring temperature accordingly.
You can also try changing the colour of your jar. Transparent jars make wet spots more visible, so switching to a coloured jar can help hide them from sight.
Additionally, consider changing the type of wax you are using. Some waxes, such as soy wax, are known to provide more consistent results and are less prone to wet spots.
Finally, while it is impossible to completely prevent wet spots due to their sensitivity to environmental changes, you can focus on creating safe, high-performance candles with strong scents and even burning. Customers often care more about the aroma and functionality of the candle rather than the appearance of wet spots.

How to fix wet spots
Wet spots are caused by temperature changes during the candle's lifecycle. When the wax melts, it turns into a liquid, and once it is poured into a jar and cools down, it starts to contract, slightly separating the wax from the jar. This results in an air pocket, giving the appearance of a wet spot. While these spots are only cosmetic and do not impact the candle's performance, there are several ways to address them.
Firstly, you can change the colour of your jar. Transparent jars make wet spots more visible, so switching to a coloured jar can help hide these imperfections.
Secondly, consider changing the type of wax you are using. Some waxes, like paraffin wax, are more prone to wet spots than others. Opt for waxes with excellent glass adhesion properties to reduce the likelihood of wet spots forming.
Another strategy is to control the temperature during the candle-making process. Pouring the wax at a cooler temperature into a pre-heated jar can help reduce the formation of wet spots. Aim for a wax pouring temperature that is close to the room temperature. Additionally, ensure that the room where the wax is cooling is not too cold; 70-72 degrees Fahrenheit is ideal.
Properly cleaning and drying your containers before pouring wax can also help. Use mild soap or a combination of dish soap and white vinegar, followed by a hot water scrub, to clean your jars. Ensure they are completely dry before pouring wax by turning them upside down on a towel or using a heat gun to accelerate the drying process.
Finally, while not a solution to fix wet spots, you can use labels or stickers to cover them. This is a simple way to hide the wet spots from view.

Customer perception of wet spots
Wet spots on candles refer to patches that appear on the sides of a candle, caused by temperature changes that lead to air pockets as the wax cools and contracts, pulling away from the container edge. While these spots are considered unsightly by candle makers, customers often do not seem to mind them. In fact, many customers who have purchased candles with wet spots have expressed that they are not deterred by these imperfections as long as the candle burns well and smells good.
Some customers even embrace the handcrafted look that wet spots create, understanding that irregularities are inherent to handmade products. This perspective is especially prevalent among buyers of Etsy products, who often value the unique and artisanal nature of the items they purchase.
While some candle makers worry that wet spots will negatively impact their sales, customer feedback suggests that scent and even burning are more important factors in their purchasing decisions. In fact, some customers specifically seek out strongly scented candles, regardless of their appearance. This suggests that candle makers may be overly critical of their own products, as even major brands and retail stores sell candles with wet spots.
To address the issue of wet spots, some candle makers have suggested using coloured jars or different types of wax with better adhesion properties. However, it is important to prioritise safety standards and scent throw, as these are the key factors that bring customers back for more. Ultimately, while wet spots may be a concern for candle makers, they do not seem to significantly impact customer satisfaction or loyalty.

Impact of wet spots on candle performance
The presence of wet spots on candles can impact their aesthetic appeal, but these cosmetic issues do not influence the functional performance of the candles. Wet spots are caused by temperature changes during the candle's lifecycle, which leads to the wax pulling away from the container's edge, creating air pockets and an uneven finish. While some customers may not notice or care about these imperfections, others may find them displeasing.
The occurrence of wet spots is a common issue in the candle-making industry, affecting even prominent brands and retail stores. These adhesion problems are primarily caused by fluctuations in temperature and environmental conditions, which are challenging to control. Candle makers can employ strategies such as using different types of wax with better adhesive properties, altering the pouring temperature, or switching to coloured jars to mitigate the visibility of wet spots. However, completely avoiding wet spots is a difficult task.
Although wet spots do not impact the performance or safety of the candle, they can be undesirable from a presentation standpoint. Candle makers may feel anxious about the appearance of their products and worry about customer satisfaction. In some cases, the adhesion issues may cause concern if the candle might pop out of its container. However, these concerns are often unfounded, as customers who appreciate handcrafted items are typically understanding of irregularities and imperfections.
To address wet spots, some candle makers use heat guns to re-melt and settle the wax. While this technique can be effective, it may introduce more problems than it solves. Instead, focusing on creating safe, high-performance candles with appealing scents and even burning is recommended. Ultimately, while wet spots may be visually unappealing, they do not affect the functionality of the candle, and customers primarily value scent, safety, and even burning in their purchases.
In conclusion, wet spots on candles are a common occurrence that results from temperature changes and environmental factors. While they may detract from the candle's aesthetic appeal, they do not hinder its performance or safety. Candle makers can employ various strategies to minimise the appearance of wet spots, but ultimately, focusing on scent, safety, and functionality is more critical to customer satisfaction.
