Repouring a candle involves adding a thin layer of melted wax to a candle after it has cooled to smooth out its surface and improve its appearance. Candle repouring is typically done for aesthetic purposes, as uneven surfaces or indentations may form during the cooling process, particularly when using hard waxes or pouring in a cold room. Repouring can also be necessary if the wrong wick is used or an additive is forgotten. To repour a candle, one must first melt and remove the existing wax, which can be done by placing the candle in a saucepan with water and heating it. While repouring can help address surface issues, it is important to note that it may result in a loss of fragrance and should be done carefully to avoid overheating the wax.

What You'll Learn
When the wax has an uneven surface after cooling
Repouring a candle is typically done to add a thin layer of melted wax to the top of the candle after it has cooled, to smooth out any unevenness and enhance its appearance. This process is often referred to as the "second pour".
Candle makers usually repour candles for aesthetic reasons, as uneven surfaces can make the candles look less appealing. Divots or indentations around the wick are common occurrences, as wax tends to cool and harden faster around the edges of the container and wick, while the centre cools more slowly. This can result in the wax pulling inwards and creating indentations.
Certain types of wax are more prone to forming uneven surfaces. Hard waxes, such as beeswax, pillar wax, paraffin, and blends with high paraffin content, are more likely to produce uneven tops due to their faster cooling and hardening properties. Pillar blends are designed to shrink as they cool, which can aid in removing the candle from the mould but may also contribute to an uneven surface. In contrast, soft waxes typically yield smoother tops on the initial pour and are often referred to as single-pour waxes. Popular blends like Ceda Serica, CB2, and EC-26 usually result in smooth tops in candle jars. Soy wax falls in between these categories and may require a second pour, depending on factors such as room temperature and pouring temperature.
To address an uneven surface after the candle has cooled, you can perform a second pour by adding a thin layer of melted wax to the top of the candle. This process will smooth out any unevenness and improve the overall appearance of the candle. Alternatively, for minor imperfections, you can use a heat gun to gently melt the surface and even it out. However, for deeper divots or sinkholes, repouring is the recommended approach.

If the wax shrinks away from the container
Repouring a candle involves adding a thin layer of melted wax to a candle after it has cooled to smooth out its surface and improve its appearance. This process is typically done for aesthetic purposes, as it does not usually affect the candle's burning performance.
To prevent significant shrinkage and ensure a smooth finish, it is recommended to pre-heat the container before pouring the wax. Warming the container helps slow down the cooling process of the wax, reducing the likelihood of shrinkage. An effective method is to pre-heat glassware in a warm oven set below 100 degrees Fahrenheit. This technique is especially useful for soy wax, which falls in the middle of the hardness spectrum and may require a second pour depending on room temperature and pouring temperature.
Additionally, it is crucial to pour the wax slowly into the containers. This slow pouring minimizes the introduction of additional air into the wax, promoting an even cooling rate. Gently tapping the sides of the containers after pouring can help release any trapped air bubbles. Spacing the candles about 4 inches apart during the cooling process and using a wire cooling rack instead of a solid surface can also encourage even cooling and reduce the chances of the wax pulling away from the container.
In some cases, if the candle has already shrunk away from the container, you may need to melt and repour the entire candle. This process involves removing the existing wax from the container by warming it in a saucepan with water or using an oven to melt the wax. Once the wax is soft, it can be removed, and new wax can be poured, ensuring a more even finish.

To smooth out the tops of candles
Temperature plays a significant role in the smoothness of a candle's surface. When wax cools, it contracts and hardens faster around the edges of the container and wick. This can cause the rest of the wax to be pulled inwards, creating indentations and divots. These indentations are more likely to form if you pour your candles in a cold room. Additionally, soft waxes typically create smoother tops on the first pour, while hard waxes like beeswax, pillar wax, and paraffin blends tend to cool faster and produce larger indentations. Soy wax falls in the middle, and some soy candles may require a second pour.
To smooth out the tops of your candles, you can use the "repour" technique, which involves adding a thin layer of melted wax, also known as a second pour. This method is particularly useful for deeper divots or sinkholes. Alternatively, you can use a heat gun or hairdryer to melt and smooth the surface of your candles. A heat gun is more suitable for minor surface issues, while repouring is ideal for more significant imperfections.
To prevent temperature-related issues, you can heat the containers before pouring the wax or store them in a warm area as they cool. Preheating your oven to a low temperature, turning it off, and placing the newly poured candles inside can also help slow the cooling process and promote even cooling. Additionally, maintaining a consistent room temperature and ensuring proper fragrance oil mixing can help achieve smoother candle tops.
Another technique to achieve a smooth top is to use the "top pour" method. This involves leaving a few millimeters of empty space at the top of the jar, allowing the wax to set, and then pouring additional wax on top to create a smooth surface.
Remember, it's always a good idea to make a test candle before creating a large batch. This will help you determine if your wax requires a second pour and allow you to choose the right wick for your candles.

To fix deeper divots
Repouring a candle involves adding a thin layer of melted wax to the candle after it cools to smooth out its surface and improve its appearance. This process is typically done for aesthetic purposes, as divots or indentations around the wick do not usually affect how the candle burns. However, deeper divots can be more noticeable and may require a second pour or repouring.
- Test: Before attempting to fix deeper divots in a large batch of candles, it is advisable to make a test candle. This helps you determine if your wax blend requires a second pour and choose the appropriate wick.
- Prepare: Choose a wax blend that is suitable for your project. Soft waxes, such as Ceda Serica, CB2, and EC-26, typically create smooth tops on the first pour and are known as single-pour waxes. Hard waxes like beeswax, pillar wax, paraffin, and paraffin blends tend to cool more quickly, resulting in larger indentations. Soy wax falls in the middle, and some soy candles may need a second pour, depending on factors like room temperature and pouring temperature.
- Melt: To fix deeper divots, you will need to melt and repour the candle. Place the candle in a saucepan filled one-quarter full with water and heat it gently on the stove like a double boiler. This will soften the wax without requiring direct heat, which can be unsafe.
- Remove Old Wax: Once the wax around the edges has softened, carefully remove the candle from the saucepan and extract the old wax. You can use tongs or similar tools to lift the wax out gently.
- Prepare for Repour: Return the old wax to your wax melting pot to melt it down again. Ensure you have enough melted wax to fill in the deeper divots and create a smooth top.
- Repour: Carefully pour the melted wax into the candle container, filling in the divots and creating an even surface. Allow the wax to cool and harden, then inspect the results.
- Repeat if Necessary: Depending on the depth of the original divots and the amount of wax used in the repour, you may need to repeat the process to achieve a completely smooth surface.
By following these steps, you can effectively fix deeper divots in your candles, creating a more aesthetically pleasing result. Remember to work carefully with hot wax and always supervise the melting process to ensure safety.

If you used the wrong wick
Repouring a candle involves adding a thin layer of melted wax to a candle after it has cooled to smooth out its surface and improve its appearance. Candle repouring is typically done for aesthetic purposes, as uneven surfaces or indentations around the wick can make candles look sloppy.
To determine if you need to use a larger or smaller wick, pay attention to the amount of smoke produced and the size of the melt pool. If you see a thick, steady stream of smoke or large puffs of smoke, it indicates that your wick is too thick, and you should use a smaller size. Conversely, if the wick is too small, the flame may only melt the middle of the candle, and you should try using a larger wick.
When repouring a candle due to a wick issue, it is necessary to start over from scratch. This involves removing the existing wax from the container by warming it and melting the wax. An easy method is to place the candle in a saucepan partially filled with water and heat it gently. Once the wax softens, remove it from the container and return it to your wax melting pot. Then, follow the standard candle-making process, ensuring you choose the appropriate wick size for your new candle.
To avoid the hassle of repouring, it is recommended to make a test candle before producing a large batch. This allows you to choose the right wick size and determine if your wax blend requires a second pour to achieve a smooth surface.
