Melt wax to fill in cracks
While it is possible to repair a broken candle, it will never look as perfect as it did before. That said, there are a few ways to fix a cracked candle by melting wax to fill in the cracks.
First, melt a small amount of candle wax in a double boiler. If you have a broken beeswax taper, melt beeswax. If you have a broken paraffin candle, melt paraffin wax. You can also melt wax by placing glass jars directly into hot water. Alternatively, chunk the wax and then put the melting pot into the water.
Next, lay the broken candle on some old newspaper, wax paper, or baking parchment paper. If there is a noticeable gap, drip the wax of a like-coloured taper into the crack, allowing each layer to harden, and then drip additional wax onto the layers until sufficient bulk has been formed to fill in the crack. Work quickly, as the wax will cool as soon as it touches the air. You can also use a paintbrush to paint some wax inside the crack.
If you are making candles in a country where AC usage is prevalent, your candles may crack due to cooling too quickly. To prevent this, allow your candles to cool down gradually and maintain a steady temperature in the room. Keep your candles away from the freezer, as they will become brittle and likely break.
When candles are cooled, they will cool unevenly if kept close together. To prevent this, ensure there is a distance of 2 to 3 inches between jars. Elevate the candles with a wire rack or a towel beneath them and cool them from the bottom up.

Use a heat gun to smoothen the surface
If your candle has cracks on its surface, one way to fix it is by using a heat gun. A gentle blast from a heat gun can help smoothen the surface of the candle and fill up the cracks. This method is especially useful if the cracks are caused by over-stirring, which creates small air bubbles that burst and cause the surface to crack.
To use a heat gun effectively for this purpose, follow these steps:
Firstly, ensure that you are working in a well-ventilated area as the heat gun will produce hot air and fumes. Always exercise caution when operating any heating equipment, including a heat gun. Before beginning, make sure the candle is placed on a heat-resistant surface to avoid damaging your work area.
Next, turn on the heat gun and adjust the temperature to a suitable setting. You may need to experiment with different temperature settings to find the optimal level that will effectively melt the candle's surface without causing further issues.
Hold the heat gun at a safe distance from the candle, approximately 2 to 3 inches away. You don't want to hold it too close, as this may cause the wax to melt too quickly or unevenly. Slowly move the heat gun across the surface of the candle, focusing on the cracked areas.
As you apply heat to the candle, you will notice that the wax begins to melt and soften, filling in the cracks. Continue applying heat until the cracks are visibly smoothed out and filled. Take your time with this process, as rushing may result in uneven results or further cracking.
Finally, allow the candle to cool down gradually. This step is crucial, as cooling the candle too quickly was likely the cause of the surface cracking in the first place. Maintain a steady room temperature of around 18°C to 20°C during the cooling process.
By following these steps and using a heat gun, you can effectively smoothen the surface of a cracked candle and give it a more uniform appearance.

Avoid quick cooling
The most common cause of candle cracking is cooling the candles too quickly. This often happens when candles are crafted in countries with high AC usage, like the United Arab Emirates. To prevent this, it is recommended to maintain a steady room temperature of around 18-20°C when cooling your candles. Avoid placing candles near the freezer, as this will cause them to become brittle and more prone to breaking.
To ensure a gradual cooling process, keep your candles at room temperature and avoid extreme temperatures. You can also pre-heat your candle vessels before pouring the wax to slow down the cooling. Maintaining a consistent temperature throughout the room is crucial to preventing rapid cooling and potential cracking.
When cooling multiple candles, keep a distance of 2 to 3 inches between the jars or containers. This spacing prevents heat from being trapped between adjacent candles, which can lead to uneven cooling and cracking. Elevating the candles on a wire rack or placing a towel underneath them can also aid in achieving even cooling.
Additionally, consider using a heat gun to gently re-melt the candle's surface, smoothing out any cracks that may have formed during the initial cooling process. This technique can be particularly effective for quick fixes if you notice cracks appearing on the surface.

Maintain a safe distance between jars
Maintaining a safe distance between jars is crucial to prevent cracking in your candles. When glass containers are placed too close together, heat becomes trapped on adjacent sides, causing uneven cooling. As a result, the sides of the jar cool more slowly than the rest, leading to cracks on the surface.
To avoid this issue, ensure a distance of 2 to 3 inches between each jar. This spacing allows for proper airflow and even cooling of all sides of the jars. Elevate the jars with a wire rack or place a towel underneath them to enhance airflow and promote even cooling from the bottom up.
Additionally, it is essential to control the room temperature when making candles. Aim for a steady temperature of around 18°C to 20°C (64°F to 68°F) to prevent rapid cooling, which can also cause cracking. Avoid using air conditioning or placing candles near open windows, as sudden temperature changes can affect the cooling process and increase the likelihood of cracks.
Taking these precautions and maintaining a safe distance between jars will help ensure your candles cool evenly and reduce the chances of surface cracking. By controlling the temperature and providing adequate airflow, you can create smooth and aesthetically pleasing candles.

Use a pouring pot to pour wax slowly
To fix a cracked candle, you can use a pouring pot to pour wax slowly and fill in any cracks or holes. Here's a step-by-step guide:
First, prepare your workspace by laying out some old newspaper, wax paper, or baking parchment paper. This will protect your work surface from any spills or messes. Then, gather your materials, including a pouring pot, the candle you want to repair, and some extra wax. The extra wax should be the same type as the candle you're repairing, such as beeswax or paraffin wax.
Next, melt a small amount of the extra wax in the pouring pot. You can do this by placing the pot directly into a pot of boiling water or using a double boiler. Ensure that the wax is fully melted and liquefied before proceeding. If you need to add colour or scent to match your candle, do so now. It is important to work quickly as the wax will start to cool and solidify as soon as it is removed from the heat source.
Once your wax is melted, slowly and carefully pour it into the cracks or holes of the candle. Hold the candle and the pouring pot steady to avoid any spills. You can use a toothpick or a similar tool to help guide the wax into the cracks and ensure it penetrates deep into the candle. Take your time with this step to avoid making a mess or causing uneven pouring.
After filling the cracks, allow the wax to cool and harden completely. This may take some time, depending on the amount of wax you used and the temperature of your workspace. Do not move or disturb the candle during this process to avoid any distortions or new cracks forming.
Finally, inspect your work. If there are still noticeable cracks or gaps, you may need to repeat the process or use a different method to fill them. However, if you are satisfied with the results, your candle is now ready to be burned or displayed again. Remember always to burn candles safely and never leave them unattended.
