Candle-making is an enjoyable craft, but it can be frustrating when your candle gets stuck in its mould. This often happens with candles made from beeswax, which does not shrink as it cools. To prevent this, you can use a mould release agent, which acts as a barrier or lubricant between the wax and the mould. There are several types of release agents available, including sprays, oils, and waxes. However, some moulds, such as silicone moulds, do not require a release agent as most waxes won't stick to them. Additionally, the type of wax you use can impact the ease of mould release, with harder waxes like paraffin being easier to remove from moulds.

What You'll Learn
Choosing the right wax
Type of Candle
The type of candle you want to make will determine the best type of wax to use. For example, beeswax is ideal for crafting free-standing pillar candles due to its hardier nature, while paraffin wax is versatile and can be used for everything from container candles to thick pillars. If you're making decorative candles, consider using gel, which creates a see-through look and allows you to add small objects like dried flowers or seashells.
Fragrance
The type of wax you choose will impact the fragrance of your candle. Paraffin wax is considered the best option for achieving a strong fragrance as it holds onto scent well. Other waxes, like coconut wax, are also known for their excellent scent throw, while soy wax is somewhere in the middle when it comes to fragrance performance.
Budget
Cost is an important consideration when choosing a wax. Paraffin wax is generally the most inexpensive option, making it a popular choice for candle makers. Soy wax is also budget-friendly, while beeswax and coconut wax tend to have higher price points.
Clean Burn and Eco-Friendliness
If a clean burn and sustainability are important to you, consider waxes like beeswax, coconut wax, or rapeseed wax. These waxes burn cleanly with minimal soot production and are more eco-friendly options. Paraffin wax, on the other hand, is derived from the oil industry and releases soot when it burns, raising questions about its environmental impact.
Customisation
If you want to customise your candles, consider using blended waxes. These allow you to fine-tune the performance of your candles by combining the benefits of natural and synthetic waxes. You can experiment with different blends to achieve the perfect balance between fragrance, burn quality, and aesthetic.
In summary, the right wax for your candle-making project depends on various factors, including the type of candle, fragrance strength, budget, sustainability, and customisation options. By considering these factors, you can choose the wax that best aligns with your preferences and project requirements.

Using mould release spray
Candle-making can be a fun and rewarding hobby, but it's essential to take the necessary steps to ensure a smooth and stress-free process. One crucial aspect is using mould release spray, which can make releasing your candles from their moulds a breeze. Here are some detailed instructions on using mould release spray effectively:
Clean the Mould:
Before applying the mould release spray, ensure that the mould is clean and free of any debris, grease, oil, or dirt residues. Use a clean cloth and rubbing alcohol to wipe the inside of the mould, removing any buildup. This step is crucial as oil and grease can inhibit the effectiveness of the mould release spray.
Prepare the Mould Release Spray:
Shake the can of mould release spray thoroughly to ensure the contents are well mixed. Mould release sprays are typically available as aerosol sprays, making them easy to apply. You can find these sprays at craft stores, online, or even on Amazon.
Apply the Mould Release Spray:
Hold the can of mould release spray 8 to 12 inches away from the mould and coat the entire surface evenly. Spray as finely as possible to ensure a thin, even layer of the release agent on the mould's surface. This layer will act as a barrier between the wax and the mould, making it easier to remove the candle once it has set.
Allow Drying Time:
After applying the mould release spray, wait for it to dry completely. This usually takes just a few minutes. Once dry, you can proceed with pouring your wax into the mould.
Release the Candle:
Once your candle has completely cooled and hardened, it's time to release it from the mould. Gently twist and turn the mould to release the candle. Avoid forcing it out, as this can lead to breakage. If needed, place the mould in the freezer for a few hours before attempting to release the candle, as this can help shrink the wax and make removal easier.
By following these steps and using mould release spray, you can ensure that your candles release smoothly from their moulds, resulting in beautiful, intact creations. Happy candle-making!

Using mould release oils
Candle-making can be a fun and rewarding hobby, but it's not without its challenges. One of the most common issues is getting your handmade candles out of their moulds without breaking or ruining them. This process is called "demoulding" or "release", and there are several techniques and tips to ensure it goes smoothly. One effective method is to use mould release oils.
Mould release, in the context of candle-making, refers to a substance that prevents the candle wax from sticking to the interior of the mould. It creates a barrier or acts as a lubricant, making it easier to remove the candle once it has cooled and solidified. There are various types of mould release agents, and one popular and effective option is mould release oils.
Mould release oils, also known as release agents, are typically natural oils such as vegetable oil, coconut oil, or mineral oil. These oils are applied to the interior of the mould before pouring in the wax. They create a thin, even layer that acts as a barrier, preventing the wax from sticking to the mould and making demoulding a breeze.
To use mould release oils effectively, follow these steps:
- Start with a clean mould: Ensure the mould is free of any debris, residue, grease, or dirt from previous candle-making sessions. Wipe the inside of the mould with a clean cloth and rubbing alcohol to remove any impurities.
- Apply the mould release oil: Using a soft, lint-free cloth, rub a thin layer of the oil onto the inside of the mould. Stand the mould upside down on a newspaper and let any excess oil drip away. Give it a final wipe before pouring in the wax.
- Prepare your wax and mould: Different types of wax may impact the ease of mould release. Additionally, consider using additives such as stearin or other hardeners to help the candle pull away from the sides of the mould.
- Allow the candle to cool and harden completely: This step is crucial. Let the candle cool for several hours, depending on its size and type. You can also place the mould in the freezer for a few hours to help shrink the wax and make removal easier.
- Remove the candle from the mould: Once the candle is fully set, gently twist and turn the mould to release it. Avoid forcing it out, as this can lead to breakage.

Preparing the mould
Clean the Mould:
Start by thoroughly cleaning the mould to ensure any residual wax, dirt, or debris from previous candle-making sessions is removed. Use a clean cloth and rubbing alcohol to wipe down the inside of the mould, eliminating any buildup. This step is essential, especially when using silicone moulds, as oil and grease can inhibit the effectiveness of the releasing agent.
Apply a Release Agent:
The next step is to apply a release agent, also known as a mould release spray or oil, to the inside of the mould. This creates a barrier between the wax and the mould, making it easier to release the candle once it has hardened. There are several types of release agents available:
- Release Sprays: These aerosol sprays are designed specifically for candle-making. They create a thin, even layer on the mould's surface, allowing the candle to slide out easily.
- Release Oils: Natural oils such as vegetable oil, coconut oil, or mineral oil can be used. These act as a barrier and make demoulding a breeze.
- Paraffin Wax: Some candle makers use a thin layer of melted paraffin wax as a release agent. It helps the candle separate from the mould smoothly.
When applying the release agent, it's crucial to use the right amount. Test it on a small area of the mould first to ensure compatibility with your specific mould and wax combination.
Choose the Right Wax:
The type of wax you use also impacts the ease of mould release. Beeswax, for example, tends to be sticky and may require a release agent. On the other hand, waxes like paraffin and soy wax naturally shrink as they cool, often releasing from the mould without additional help. Harder waxes with higher melting points are better suited for free-standing candles.
Consider the Mould Material:
The mould material also plays a role in preparing for an easy release. Silicone moulds are often non-stick and may not require a release agent. They are durable and can withstand high temperatures, but they are costly. Metal moulds, on the other hand, usually require a release agent, especially when using sticky waxes like beeswax.
Remember, proper mould preparation is key to a stress-free candle-making experience. Take your time, follow these steps, and enjoy creating your candle masterpieces!

Cooling and removing the candle
Cooling and removing your candle from its mould is a delicate process. It is important to be patient and let the candle cool completely before attempting to remove it. The cooling time can vary depending on the size and type of candle, as well as factors such as ambient temperature and humidity.
To speed up the cooling process, you can place the mould in the refrigerator, which will help the wax set and separate from the mould. However, do not leave the mould in the refrigerator for too long, as this can cause the wax to shrink too much and crack. Flip the mould every 30 minutes to ensure even cooling. If you are in a hurry, you can also place the mould in the freezer for at least half an hour. This will cause the wax to contract, making it easier to remove.
Once the candle has cooled and hardened, you can try to remove it from the mould. If you are using a rubber mould, you will need to unwrap the wick before removing the candle. For silicone moulds, simply flex and peel back the sides of the mould until the candle slips out. If you are using a metal mould, you can try using a heat gun or blow dryer on the lowest setting to soften the wax and free the candle.
If the candle is still stuck, you can try tapping on the bottom of the mould or gently tugging on the wick. For latex rubber moulds, a mixture of vybar and paraffin wax is recommended. You can also use a small amount of mould release spray or oil to create a barrier between the wax and the mould, making it easier to release the candle.
If all else fails, you may need to use boiling water to remove the candle. Place the mould in a metal dish filled with boiling water and wait for the candle to soften. After a few minutes, you can retrieve the candle using tongs or a wooden spoon. While this may not save your candle, you can melt down the wax for your next attempt.
