What You'll Learn
Use harder waxes like paraffin wax, beeswax, or pillar wax blends
When making candles, one of the most crucial steps is demoulding—removing the candle from its mould without causing any damage. Harder waxes, such as paraffin wax, beeswax, or pillar wax blends, are better for moulds. Harder waxes tend to shrink away from the edges of the container as they cool down, making it easier to pop the candle out of the mould. Paraffin wax is durable and will shrink slightly as it cools, making it easier to demould. Pillar wax blends are specifically formulated for pillar candles and other moulded candles, and they pair well with paraffin wax. Beeswax also tends to shrink like paraffin wax, but some find it harder to work with.
If you are using a silicone mould, you can carefully make a slit along the backside of the mould to ease the removal of the finished candle. Use a sharp craft knife to make a clean, precise cut. You can reinforce the slit with rubber bands or clips during pouring to prevent leakage.
Additionally, you can use vegetable cooking oils as a natural release agent in steel or plastic moulds. Rub a thin layer of oil onto the inside of the mould with a soft, lint-free cloth, then let the excess oil drip away. You can also use olive oil in the same way.
For latex rubber moulds, a mixture of 0.5-1% vybar and paraffin wax works well. Avoid stearin, as it rots these flexible mould types. For metal moulds, use a candle release spray or lotion, with or without silicone.
Remember to be patient and efficient when removing the candle from its mould. Allow the mould to cool completely before removing the candle, as trying to remove it too early may cause the surface of the candle to tear and crumble. You can speed up the cooling process by placing the mould in the refrigerator, flipping it every 30 minutes to ensure even cooling.

Avoid soft waxes like soy wax or coconut wax
When making candles, it is important to choose the right type of wax for the desired outcome. Soy wax and coconut wax are both soft waxes that are popular for hair removal, but they may not be the best choice for candle-making.
Soy wax is a natural, user-friendly product that is easy to handle, measure, and melt, making it a great option for beginners. It has a strong fragrance throw and an extended burn time, but it can be tricky to achieve a strong scent. Soy wax often has a bumpy or cratered surface after burning, and it adheres easily to the walls of containers. This can be beneficial for those who want to ensure they are using a natural product, but it may not be desirable for those seeking a smooth finish. Soy wax is best suited for container candles, tealights, wax melts, and tarts.
Coconut wax is another soft wax that is commonly used for hair removal. It has a creamy texture and a sweet coconut scent, making it a pleasant option for waxing. Coconut wax is formulated with premium-quality hypoallergenic resins and titanium dioxide, which make it easy to spread and gentle on the skin. While coconut wax may have benefits for skincare, it may not be the best choice for candle-making due to its soft and creamy nature.
To avoid the challenges that come with using soft waxes, candle makers can opt for harder waxes such as paraffin wax or beeswax. These waxes may provide more stability and ease of removal from moulds. Additionally, additives like stearin can be mixed into the wax to harden it and aid in the demoulding process.
Overall, while soy wax and coconut wax have their advantages in other applications, they may not be the ideal choice for candle-making due to their soft and sticky nature. Harder waxes and appropriate additives can help ensure that candles release more easily from their moulds.

Use mould release sprays or lubricants
Mould release sprays or lubricants are a great way to prevent candles from sticking to the mould. These sprays or lubricants create a thin, even layer on the mould's surface, acting as a barrier between the wax and the mould. This makes it easier for the candle to slide out once it has set.
There are a variety of mould release sprays and lubricants available, each with its own advantages and considerations:
- Release Sprays: These are aerosol sprays specifically designed for candle-making. They are easy to use and create a thin, even layer on the mould's surface. However, it is important to note that all release sprays are flammable, so they should be used in well-ventilated areas away from open flames.
- Release Agents or Oils: Natural oils such as vegetable oil, coconut oil, mineral oil, or olive oil can be used as release agents. These oils are applied to the mould's interior, creating a barrier that makes it easier to remove the candle. They are a cost-effective and natural alternative to other release sprays.
- Paraffin Wax: A thin layer of melted paraffin wax can be brushed onto the interior of the mould as a release agent. This creates a barrier that helps the candle separate from the mould. However, it is important to use the correct amount as too much can affect the appearance of the candle's surface, and too little may not provide adequate release.
- Dishwashing Liquid: For latex rubber moulds, rub dishwashing liquid onto the outside of the mould and pull it back on itself. This helps with candle release, especially with flexible mould types.
When using any mould release spray or lubricant, it is important to follow the instructions on the product and test it on a small area of the mould first to ensure compatibility with your specific mould and wax combination. Additionally, some moulds, such as plastic moulds, may not require a mould release agent if they have a smooth and non-stick surface.

Cool candles in the fridge to loosen them
Cooling candles in the fridge is an effective way to loosen them from their moulds. This method works because the wax shrinks slightly as it cools, making it easier to remove the candle without damaging it. It is important to wait until the candle has completely set and cooled to room temperature before placing it in the fridge, as a drastic temperature change can cause the candle to crack.
The length of time the candle spends in the fridge depends on the type of mould. Plastic, glass, acrylic, or polycarbonate moulds should be placed in the fridge for around 20 minutes. Metal moulds can be placed in the fridge for longer, and silicone moulds can be left in until the wax has fully set and cooled. It is important to note that the candle should not be left in the fridge for too long, as this can cause cracking.
Before placing the mould in the fridge, it is important to ensure that the mould is prepared properly. The mould should be clean and free of any debris or residue from previous candle-making sessions. A release agent, such as a thin layer of oil or mould release spray, can be applied to the inside of the mould to create a barrier between the wax and the mould, making it easier to remove the candle.
Once the candle has been in the fridge for the appropriate amount of time, it can be removed from the mould. This can be done by gently twisting and turning the mould to release the candle. If the candle is still stuck, other methods can be used, such as lightly tapping on the bottom of the mould or gently tugging on the wick.

Use vegetable oil or olive oil as a natural release agent
To prevent candles from sticking to moulds, you can use vegetable oil or olive oil as a natural release agent. This method works well with steel or plastic moulds and does not cause mould erosion.
To use this method, start by rubbing a thin layer of vegetable oil or olive oil onto the inside of your mould. Use a soft, lint-free cloth to avoid scratching the mould. Place the mould upside down on a newspaper and let any excess oil drip away. Give it a final rub, and you're ready to pour your candle wax.
If you're using olive oil, you can add your favourite candle scents or essential oils. You could even add dried herbs for a natural scent. However, it's important to note that olive oil may not be suitable for wicks, as it has a lower flash point than other oils, and it will consume the wick quickly.
If your candle is already stuck in the mould, you can try running boiling water over the outside of a metal mould for a few seconds, then pulling hard on the wick. Alternatively, place the mould, wax, and all into a metal dish with boiling water to melt the candle out.
