Making beeswax candles is a fun and rewarding project, but it can be frustrating when things go wrong. One common issue is the formation of cauliflower tops or bumpy tops on the candles due to polymorphism, which occurs when there are temperature fluctuations as the liquid wax cools and solidifies. To prevent this, it is important to place your candles on a wire rack instead of a solid surface, as solid surfaces can cause the wax to cool too quickly and unevenly. Additionally, ensuring that your candles cool slowly in a warm environment can help prevent this issue. Another tip is to use softer waxes or blend them with harder waxes, making it less likely for the wax to contract and pull away from the glass. By following these suggestions, you can create smooth and aesthetically pleasing beeswax candles.

Avoid quick cooling to prevent cracks
Beeswax candles are prone to cracking, especially if they are large-diameter candles. This is because beeswax shrinks as it cools, and rapid cooling can cause the wax pool to harden and crack. To avoid cracks, it is important to cool your candles gradually in a warm area. Here are some tips to prevent quick cooling and reduce the likelihood of cracks forming in your beeswax candles:
Firstly, maintain a steady temperature in the room to keep your candles at room temperature. Avoid placing your candles near air conditioning units or in rooms with high air circulation, as this can cause the candles to cool too quickly. If possible, cool your candles in a warm area of your house, such as on top of a stove or in an oven that has been turned off. This will help to prevent extreme temperature changes that can lead to cracking.
Secondly, try to avoid quick cooling by allowing your candles to cool down gradually. Instead of placing them in a freezer or cold environment, let them cool at room temperature. You can also try slowing down the cooling process even further by placing the candles in an oven that has been turned off, leaving them overnight to cool gradually.
Additionally, when making container candles, it is important to pour the wax at the right temperature. If the wax is too hot, it can cause cracking. The ideal temperature for pouring beeswax is between 155-160°F (68-71°C). At this temperature, the wax will start to form a film on the top, indicating that it is ready for pouring.
Furthermore, when making large container candles, it is recommended to pour at a lower temperature for your first pour to reduce shrinkage and cracking. Try pouring at around 150°F (65°C), just above the temperature where the wax starts to skin over. Then, wait for the first pour to solidify before proceeding with the second pour at a higher temperature of around 185°F (85°C).
By following these tips, you can help prevent quick cooling and reduce the likelihood of cracks forming in your beeswax candles. Remember, if cracks do occur, it is not a flaw in your candle-making process but a natural occurrence due to the properties of beeswax.

Maintain a steady room temperature
Beeswax candles are prone to cracking, especially if they are large container candles. This is because beeswax shrinks as it cools. The larger the diameter of the candle, the more likely it is to crack on top after cooling.
To prevent cracks, it is important to maintain a steady room temperature to keep your candles at room temperature. Avoid using air conditioning as this can cause the candles to cool too quickly. If you live in a hot country, try using a fan instead of air conditioning to keep the room temperature steady.
Let the candles cool slowly in a warm area of your house. You can also try letting a batch cool slowly in the oven with the door shut. Keep the oven temperature low and warm rather than hot.
If you are making candles in a cold climate, make sure the room is warm enough so that the wax doesn't harden into clumps and splash into the container as you pour.
If you are making candles in a warm climate, make sure the room temperature is not too hot, as this can cause the wax to crack or form air bubbles.

Don't freeze beeswax candles
While beeswax candles can freeze, it is not advisable to freeze them. This is because the wax can crack as a result of the freezing temperature. Freezing beeswax candles will not change their crystalline structure, and therefore will not have any significant effect on the candle.
Beeswax candles should be stored in a cool, dry place, away from direct sunlight. Extreme temperatures can negatively affect beeswax candles. If the temperature is too high, beeswax can become soft and misshapen. Very cold temperatures can cause the wax to become brittle and crack. The ideal storage temperature for beeswax candles is between 60-80°F (15-27°C).
Beeswax candles are a natural, eco-friendly lighting option for your home. They offer a hypoallergenic option, ideal for those with sensitivities. They burn clean and bright, with a subtle honey scent, and have a long burn time. To keep them in optimal condition, it is important to store and care for them properly.
Beeswax candles may develop a white, powdery film on their surface, known as beeswax bloom. This is a natural process caused by the movement of natural oils to the surface of the wax. While beeswax bloom is harmless and does not affect the quality or burn of the candle, it can be removed by wiping the candle with a soft cloth or gently warming the surface with a hairdryer.

Prevent air bubbles by minimising stirring
Beeswax candles are a natural and sustainable product, but they can be prone to cracking, especially if you live in a hot country where the wax cools quickly. One way to prevent cracks is to minimise stirring during the candle-making process. Small air bubbles can be created by over-stirring, which then get trapped during the cooling process. As the bubbles get smaller, they eventually burst, leading to a cracked surface.
To prevent this, you should only stir your mixture gently and slowly. You can also use a heat gun to re-melt the candle surface, which helps to smoothen it out and fill in any cracks. If you are adding essential oils to your candles, you will need to stir the mixture, but only do so gently and avoid over-stirring.
Another way to prevent cracks is to control the temperature of the wax during the cooling process. Beeswax cracks when it cools too quickly, so it is important to let your candles cool down gradually in a warm area of your house. You can also try letting them cool slowly in the oven with the door shut. Avoid putting your candles in the freezer, as this will make the wax brittle and more likely to crack.
Finally, you can prevent cracks by pouring your wax at the right temperature. The ideal temperature for pouring beeswax is between 155-160°F, or when a film starts to form on top of the wax. If you pour your wax too hot, it can cause cracking or air bubbles.

Keep jars at a distance from each other
When making beeswax candles, it is important to consider the cooling process carefully to avoid cracks forming on the tops of the candles. One way to ensure this is by keeping jars at a distance from each other.
When candles are cooling, they need to be kept at room temperature, and the room temperature should be maintained at a steady level. If candles are cooled too quickly, beeswax will shrink and form cracks. This is more likely to happen in countries with high AC usage, like the United Arab Emirates.
To avoid this issue, it is recommended to keep a distance of 2 to 3 inches between jars. This is because when glass containers are placed too close together, heat gets trapped on adjacent sides, causing the sides of the jar to cool more slowly than the rest of the candle. This results in uneven cooling, which can lead to cracks.
To ensure even cooling, it is also helpful to elevate the candles with a wire rack or a towel beneath them and to encourage airflow under the candles. This will help to prevent cracks from forming on the tops of beeswax candles.

Frequently asked questions
Beeswax candles crack on top due to the shrinkage of beeswax as it cools. Larger candles are more prone to cracking than smaller ones.
To prevent cracks, cool your candle gradually in a warm area. Avoid cooling candles in close proximity to each other, as this will cause them to cool unevenly.
The ideal temperature for pouring beeswax is 155-160° F. Pouring at a lower temperature of around 150° F will reduce shrinkage and help prevent cracks.
Small air bubbles can be created by over-stirring, which will burst during the cooling process and cause cracks. To prevent this, try to stir as smoothly as possible.
If your candle has already cracked, you can use a heat gun to re-melt the surface and smooth it out. Alternatively, you can fill in any cracks with extra wax.
