Use a mould release spray
Using a mould release spray is an effective way to remove a soy candle from its mould. This method involves spraying a thin layer of mould release spray on the inside of the mould before pouring in the wax. This creates a barrier between the wax and the mould, making it easier to remove the candle without causing damage.
It is important to note that not all mould release sprays are compatible with silicone moulds, so it is crucial to double-check the compatibility of the products before use. Additionally, when choosing a mould release spray, consider the type of wax being used and the complexity of the mould. Some lubricants may work better with certain types of wax, so experimentation may be necessary to find the perfect match.
To begin the process of removing the candle from the mould, gently pull the mould apart to break the contact between the mould and the wax. Once the wax has been loosened, start peeling the mould away from the wax, being cautious with any areas that feel particularly resistant. This technique helps to prevent the candle from sticking to the mould and reduces the risk of cracks, dents, or other imperfections.
For intricate moulds, it is recommended to use release slits. These are created by cutting a slit around the problem area with a sharp blade and then using duct tape to join the mould back together before pouring in the wax. When the wax is ready to be removed, start by loosening the mould from the slit, gently peeling it away. This method is particularly useful for delicate designs that are prone to wax breakage or sticking.
By following these steps and using a mould release spray, you can effectively remove a soy candle from its mould, achieving a professional and flawless finish.

Let the wax cool completely
Allowing the wax to cool completely is a crucial step in the candle-making process. Patience is key when it comes to achieving a professional finish for your soy candle. While it may be tempting to speed up the process, attempting to remove the candle from its mold too soon can result in unwanted cracks and dents on its surface.
The time it takes for the wax to cool and harden depends on the size of the mold. Typically, wax cools within a few hours, but it is recommended to wait a full day before attempting to remove the candle. This extra time allows the wax to fully harden and maintain its shape. During this waiting period, it is important to ensure that your workspace remains clean and debris-free to prevent any unwanted particles from sticking to your candle.
To speed up the cooling process, you can place the mold in a refrigerator for a few minutes. This helps the candle wax shrink and separate from the sides of the mold, making it easier to remove. However, it is crucial not to leave the mold in the refrigerator for too long, as extended exposure to cold air can cause the wax to shrink excessively and may result in cracks. As an alternative to the refrigerator, you can also place the mold in a cooler room or use a fan to speed up the cooling process.
While you wait for the wax to cool, it is important to prepare your workspace by gathering the necessary tools. These may include a wick trimmer or scissors, gloves to prevent fingerprints and smudges, and a mold release spray or lubricant to create a barrier between the wax and the mold. A clean and organized workspace will help ensure a smooth and efficient process once the wax is ready to be removed.
Once the wax has completely cooled and hardened, you can begin the process of removing your soy candle from the mold. Gently loosen the mold by pulling it apart slightly to break contact with the wax. Then, start peeling the mold away from the wax, taking extra time and caution with any areas that feel particularly resistant. With patience and care, your soy candle will emerge from the mold flawlessly, ready for the final touches.

Put the mould in the fridge
Putting the mould in the fridge is a useful technique to employ when removing a soy candle from its mould. This method is particularly effective because, as the wax cools, it shrinks, making it easier to remove from the mould.
However, it is important to note that the mould should not be left in the fridge for too long. While wax typically cools within a few hours, it is recommended to wait a full day before attempting to remove the candle from the mould to allow the wax to fully harden and maintain its shape. Placing the mould in the fridge for a few minutes before removal can be helpful, but extended exposure to cold air can cause the wax to shrink too much, potentially resulting in cracks. Therefore, it is suggested to avoid leaving the mould in the refrigerator for more than ten minutes.
The type of wax used also plays a significant role in the mould-removal process. Soft waxes are generally recommended for containers, while hard waxes are more suitable for pillars and moulded candles. Additionally, the design of the mould should be considered. Custom-made moulds with intricate details may require a release agent, such as mineral oil or vegetable cooking oils, to be applied before pouring the wax.
It is worth noting that this technique of using the fridge is not the only method available for removing soy candles from their moulds. Alternative approaches include using flexible silicone moulds, which can be turned inside out, or creating a release slit on the side and sealing it with a rubber band. However, for those seeking a quick solution, placing the mould in the fridge can be a convenient option.

Use a flexible silicone mould
Using a flexible silicone mould for your soy candle-making is a great option, as silicone moulds are durable, flexible, and reusable. They are also capable of capturing intricate details, making them a popular choice for both professionals and hobbyists. Here are some detailed instructions on how to remove your soy candle from a flexible silicone mould:
Prepare the Mould:
Before pouring the wax into your silicone mould, it is important to prepare it properly. Apply a thin layer of lubricant or a mould release spray specifically designed for silicone moulds. This will help prevent your candle from sticking to the mould and make the removal process easier. You can also use natural alternatives like olive oil, but they may not be as effective as specially formulated products.
Allow the Wax to Cool:
It is crucial to let the wax completely cool and harden before attempting to remove your candle from the mould. This typically takes a few hours, but it is recommended to wait a full day before demoulding to ensure the wax has fully set. Placing the mould in a refrigerator or a cooler room can help speed up the cooling process and make it easier to remove the candle. However, be cautious not to leave the mould in the fridge for too long, as a drastic temperature change can cause the candle to crack.
Remove the Candle:
When the wax has fully cooled and hardened, it's time to remove your soy candle from the flexible silicone mould. Start by gently peeling the mould away from the candle, being careful not to pull or tug too hard, as this can damage both the candle and the mould. For intricate designs, take extra care to peel slowly and evenly to avoid breaking any delicate parts. If your candle is stuck, try placing the mould in the freezer for a few minutes, as the cold will cause the wax to contract, making it easier to remove.
Clean the Mould:
After successfully removing your soy candle from the mould, it is important to clean the mould promptly to prevent any wax or fragrance residue from hardening and becoming more difficult to remove. Gently scrape out any remaining wax or residue from the mould, being careful not to use sharp objects that could scratch or tear the flexible silicone surface. Finally, rinse the mould thoroughly with warm water and dry it completely before storing it in a cool, dry place away from direct sunlight or extreme temperatures.

Use a lubricant
Soy wax is a softer wax, which tends to stick to the sides of the mould. This makes it great for container candles but not ideal for moulds. Harder waxes, like paraffin wax, beeswax, or pillar wax blends, are better suited for moulds as they shrink away from the edges of the container as they cool. Therefore, if you are set on using soy wax, it is recommended to blend it with a harder wax or add an additive like stearic acid to harden it. This will make it easier to remove from the mould.
Now, to ensure your soy candle can be removed from the mould, you must use a lubricant. There are a few different types of lubricants or release agents that can be used:
Release Sprays
These are aerosol sprays specifically designed for candle-making. They create a thin, even layer of the release agent on the mould's surface, making it easier for the candle to slide out once set. You can spray the inside of the mould with a release spray one to two times. A thin coat will do the trick. Alternatively, you can use a vegetable oil spray like olive oil or coconut oil.
Release Agents or Oils
Certain oils or substances, such as vegetable oil, coconut oil, or mineral oil, can be applied to the mould's interior. These oils act as a barrier between the wax and the mould, making demoulding easier. You can pour the oil into a spray bottle and spray it on the inside of the mould, spreading it evenly with a paper towel.
Paraffin Wax
Some candle makers use a thin layer of melted paraffin wax brushed onto the interior of the mould as a release agent. This creates a barrier that helps the candle separate from the mould. It is important to use the right amount of release agent. Too much can affect the appearance of the candle's surface, and too little may not provide adequate release. Before using a release agent, test it on a small area of the mould to ensure compatibility.
It is important to note that the type of lubricant you use may depend on the type of mould. For example, for plastic and acrylic moulds, avoid silicone sprays as they can erode plastic. Use wax release alternatives specifically made for plastic moulds instead. For metal moulds, use a candle release spray or lotion, which may contain silicone.
