What You'll Learn
Prevent sinkholes by poking holes around the wick to release air.
Candle sinkholes are a common problem that can cause your candle to burn unevenly or even extinguish. They are caused by air bubbles becoming trapped beneath the surface of the wax as it cools and solidifies, leaving an air pocket. This can happen when the wax around the edges and the wick set too quickly, not allowing enough time for the air bubbles to escape.
To prevent sinkholes, one method is to poke holes around the wick while the wax is still soft. This allows any trapped air to escape and can prevent sinkholes from forming during the cooling process. It is recommended to use a toothpick to create these holes, being careful not to damage the wick.
By poking these holes, you create a pathway for the air to escape, reducing the likelihood of air pockets forming. This technique is especially useful if you are in a rush and need to speed up the cooling process. For example, if you have placed your candle in the refrigerator or outside on a cold day to cool it down quickly, poking holes around the wick can help prevent sinkholes from forming.
Additionally, allowing your candle to cool down slowly at room temperature is always recommended. Harder waxes, such as pillar and votive waxes, are more prone to sinkholes because they have a higher melting point, so using softer waxes can also help prevent sinkholes.
While poking holes around the wick is a useful technique, it may not always completely prevent sinkholes. In case a sinkhole still forms, you can use the second pour method to fill it in. This involves remelting some of the wax and slowly pouring it into the sinkhole to create a smooth surface.

Use a heat gun to fill sinkholes by melting the top layer of wax
Fixing candle sinkholes can be frustrating, but it's doable. One way to do this is by using a heat gun to melt the top layer of wax and fill in the sinkhole. Here's a step-by-step guide to help you through the process:
Step 1: Prepare Your Workspace
Before you begin, ensure you have a heat gun, extra wax, and a controlled cooling environment. It is important to work in a well-ventilated area when using a heat gun. Also, cover your workspace with newspaper or a heat-resistant mat to catch any wax drips.
Step 2: Understand Sinkholes
Sinkholes are cavities or craters that form in candles as the wax cools and sets. They can be a huge disappointment and affect how your candle burns. Understanding why they occur is essential to fixing them effectively. Temperature control is critical to preventing and fixing sinkholes.
Step 3: Use the Heat Gun
Hold the heat gun about 6 inches away from the candle's surface. Turn it on and set it to a low or medium heat setting. You don't want to melt the entire candle, just the top layer. Gently move the heat gun back and forth over the sinkhole area. Be careful not to overheat any single area, as this can cause the wax to warp or create new sinkholes.
Step 4: Fill the Sinkhole
As you gently heat the surface of the candle, the wax will start to melt. Continue until the wax around the sinkhole has slightly melted. Be careful not to scorch the wick. Once the wax is melted, carefully pour the same type of melted wax into the sinkhole. Ensure the wax is not too hot to avoid melting the surrounding wax excessively. Fill the sinkhole up to the original level of the candle, being careful not to overfill.
Step 5: Let It Cool
After filling the sinkhole with melted wax, allow the candle to cool and solidify completely. This second cooling process should be done in the same controlled environment as the first cooling to ensure even setting. You can place the candle in an oven set to a very low temperature (around 170°F or lower) to aid in the gradual cooling process.
Step 6: Smooth the Surface (Optional)
Once the candle has cooled and the wax has solidified, you may notice some unevenness or bumps on the surface. To fix this, gently melt the top layer of the entire candle with the heat gun. This will help create a smooth, even surface. You can also use a spatula or similar tool to gently smooth the surface, being careful not to apply too much pressure.
Remember, temperature control is crucial when working with wax. Always monitor the temperature of your tools and materials to prevent overheating and creating new sinkholes. With patience and practice, you'll be able to fix candle sinkholes like a pro!

Use a hairdryer to melt the wax and fill in sinkholes
Fixing candle sinkholes can be done in a few simple steps using a hairdryer. Firstly, set your hairdryer to a low or medium heat setting. You want to melt the wax, not the entire candle, so a gentle heat is best. Next, hold the hairdryer about 6 inches away from the candle's surface and move it back and forth over the sinkhole. The heat will gently melt the top layer of wax, allowing it to fill in the sinkhole. Once the sinkhole is filled, turn off the hairdryer and let the candle cool and set.
If the wax doesn't completely fill the sinkhole, it might be because the wax cooled too quickly. Try reheating it gently for a bit longer, ensuring it flows into the entire sinkhole area. If the surface of your candle is still uneven after your repair attempts, use the hairdryer method again, but this time focus on gently melting the top layer of the entire candle. This can help level out any unevenness.
When using a hairdryer, keep the tool moving and avoid overheating any area, as this can cause the wax to warp or create new sinkholes. It is also important to be careful not to scorch the wick while heating the wax.
The hairdryer method is a clever and easy way to fix sinkholes without needing professional tools. It is a great alternative to using a heat gun, which is the tool often recommended for fixing candle sinkholes.

Avoid rapid temperature changes when making candles to prevent sinkholes
When making candles, it is important to avoid rapid temperature changes to prevent sinkholes from forming. Sinkholes are cavities that can form within your candle, often next to the wick, and they can cause the candle to burn unevenly or even extinguish prematurely.
To avoid rapid temperature changes, resist the temptation to use methods that rapidly cool your candles, such as placing them in the refrigerator, setting them outside in cold temperatures, or using a fan. These quick-cooling methods can increase the likelihood of sinkhole formation. Instead, allow your candles to cool slowly at room temperature.
Additionally, choose the right type of wax for your candles. Harder waxes, like pillar and votive waxes, tend to have higher melting points, which can make them more prone to sinkholes. Opt for waxes with lower melting points or use blended candle waxes to reduce the risk of sinkholes.
Another way to prevent sinkholes is to heat your glass containers or moulds before pouring the wax. This helps to prevent poor adhesion, also known as candle wet spots, which can occur when there is trapped air between the container and the wax. Warming the container creates a better bond between the wax and the container, reducing the chances of sinkholes.
Finally, be mindful of the pouring temperature of your wax. Pouring wax that is too hot can contribute to sinkhole formation. Aim for a lower pouring temperature, but also consider the specific type of wax you are using. Some waxes, like Ecosoya CB Advanced, perform better when poured at slightly higher temperatures, while others do better at cooler temperatures. Experiment with different pouring temperatures to find the optimal range for your chosen wax.

Use blended candle waxes to prevent sinkholes
Blended candle waxes can be used to prevent sinkholes in candles. This is because sinkholes are caused by wax expanding when heated and becoming liquid, then shrinking and contracting when it cools and returns to its solid state. Harder waxes with a higher melting point, such as pillar and votive waxes, are more prone to sinkholes. Therefore, using a blend of waxes with different melting points can help to prevent sinkholes from forming.
To fill sinkholes, you can use a hairdryer on a low or medium heat setting, held about 6 inches away from the candle's surface. Gently move it back and forth over the sinkhole to melt the top layer of wax, allowing it to fill in the sinkhole. Once the sinkhole seems filled, turn off the hairdryer and let the candle cool and set.
Another way to prevent sinkholes is to poke relief holes around the wick with a toothpick after the first pour when the wax is still slightly soft. These holes help air escape and can prevent sinkholes from forming during the cooling process. If a sinkhole still forms, you can use the second pour method to fill it in. For this, ensure the wax is liquid enough to flow smoothly into the sinkhole without creating air pockets.
Additionally, heating the glass before pouring and pouring the wax at a lower temperature can also help to prevent sinkholes. Allowing candles to set slowly at room temperature is also recommended, as placing them in a refrigerator, setting them outside on a cold day, or running a fan on them can increase the likelihood of sinkhole formation.
