How to Fix Candle Sinkholes Without a Heat Gun

Candles are a delightful addition to any home, creating a warm and inviting atmosphere. However, sometimes during the candle-making process or when burning candles, sinkholes can form in the wax, leaving an uneven surface and affecting the overall aesthetics of the candle. While using a heat gun is a common method to fix sinkholes, not everyone may have access to one. But worry not, there are alternative techniques to address this issue without the need for a heat gun. In this guide, we’ll explore some simple yet effective methods to fix candle sinkholes using everyday household items.

What Causes Sinkholes in Candles?

Before we delve into the solutions, it’s essential to understand what causes sinkholes in candles. Sinkholes typically occur due to the contraction of the cooling wax. As the melted wax cools and solidifies, it shrinks, leaving depressions or sinkholes on the candle’s surface. Other factors, such as air bubbles in the wax or poor-quality wax, can also contribute to the formation of sinkholes.

My trick to avoiding sinkholes (not just a heat gun)

Method 1: Using a Hairdryer

A hairdryer can be an excellent alternative to a heat gun for fixing candle sinkholes. Here’s how to do it:

1. Prepare the Candle: Ensure the candle is placed on a flat, heat-resistant surface. You can place a towel or cloth under the candle to protect the surface.
2. Set the Hairdryer: Turn on the hairdryer to its highest heat setting. Hold the hairdryer about 6 to 8 inches away from the candle.
3. Heat the Sinkholes: Direct the hot air from the hairdryer towards the sinkholes on the candle’s surface. Move the hairdryer in a circular motion to evenly distribute the heat.
4. Observe Carefully: Be patient and observant during this process. As you apply heat, the sinkholes should start to fill in as the wax becomes more malleable.
5. Smooth the Surface: Once the wax around the sinkholes becomes soft, use a spoon or the back of a butter knife to gently press down on the softened wax, filling in the sinkholes and creating a smoother surface.
6. Let it Cool: Allow the candle to cool and solidify again. You should now have a candle with a more even surface.

Method 2: Using a Cotton Swab

Another simple method involves using a cotton swab to fix minor sinkholes. Here’s how:

1. Melt the Wax: Light the candle and let a small pool of wax form around the sinkholes. Allow the wax to melt slightly.
2. Dip the Cotton Swab: Take a cotton swab and dip it into the melted wax. Make sure the cotton swab is not soaked in wax; a thin layer is enough.
3. Fill the Sinkholes: Gently apply the melted wax from the cotton swab into the sinkholes on the candle’s surface. Be careful not to overflow the wax.
4. Smooth the Surface: Use the back of a spoon or a butter knife to smooth out the surface and blend the newly added wax with the existing wax.
5. Let it Cool: Allow the candle to cool and solidify completely before lighting it again.

Method 3: Double Boiler Method

If you have access to a double boiler, you can use it to fix sinkholes in your candles. Here’s how:

1. Prepare the Double Boiler: Fill a pot with water and place it on the stove. Set the heat to low or medium-low. Place a heat-resistant glass or metal container (the double boiler) into the pot.
2. Add the Candle Wax: Take the candle you want to fix and carefully shave some wax from the bottom using a butter knife or a grater. Place the shaved wax into the double boiler container.
3. Melt the Wax: Allow the wax to melt gently in the double boiler. Stir it occasionally to ensure even melting.
4. Fill the Sinkholes: Once the wax is fully melted, use a dropper or a small spoon to carefully add melted wax into the sinkholes on the candle’s surface.
5. Let it Cool: Allow the candle to cool and solidify in a cool and undisturbed area.

Method 4: Using a Warm Water Bath

If you don’t have access to a heat gun or hairdryer, you can use warm water to fix sinkholes. Here’s how:

1. Prepare a Bowl: Take a bowl large enough to accommodate your candle and fill it with warm (not hot) water.
2. Place the Candle: Gently place the candle with sinkholes into the warm water bath. Make sure the water level does not go above the candle’s top.
3. Wait for Softening: Allow the candle to sit in the warm water for a few minutes. The heat will soften the wax around the sinkholes.
4. Fix the Sinkholes: Using your fingers or the back of a spoon, gently press down on the softened wax to fill in the sinkholes and create a smoother surface.
5. Let it Cool: Remove the candle from the water bath and let it cool and solidify on a flat surface.

Prevention Tips

While these methods can effectively fix sinkholes in candles, prevention is always better than cure. Here are some tips to help prevent sinkholes in your future candle-making endeavors:

1. Choose Quality Wax: Opt for high-quality candle wax that is specifically designed for the type of candles you want to make.
2. Proper Cooling Time: Allow your candles to cool and solidify at room temperature without any sudden changes in temperature or drafts.
3. Avoid Overheating: Be cautious not to overheat the wax during the melting process, as extreme temperatures can contribute to sinkholes.
4. De-Airing the Wax: Before pouring the melted wax into molds, allow it to cool slightly and then gently stir to release any trapped air bubbles.
5. Layering Technique: For larger candles, consider pouring the wax in layers to minimize the chances of sinkholes forming as the wax cools.

By following these tips and using the methods outlined above, you can easily fix sinkholes in candles and create beautifully smooth and even surfaces for your creations.

Remember, candle-making is a creative and enjoyable process, so don’t be discouraged by the occasional sinkhole. With a bit of practice and these handy techniques, you’ll be making stunning candles in no time!
