What You'll Learn
Allow the wax to cool and cure completely
Allowing the wax to cool and cure completely is a crucial step in the candle-making process. Rushing this step can lead to soft spots, warping, and even cracks in your candle. Patience is critical to achieving a smooth finish. The time it takes for the wax to cool and cure will depend on the type of wax and the size of the mould. While wax typically cools within a few hours, it is recommended to wait a full day before demoulding to give the wax extra time to fully harden and maintain its shape.
During the cooling process, it is important to follow the manufacturer's instructions for the specific type of wax you are using. Each type of wax has its own curing time and temperature requirements. Adhering to these guidelines ensures that the wax sets correctly, making demoulding easier and more successful.
To speed up the cooling process, you can place the mould in the refrigerator. This will help the wax set and separate from the mould. However, it is important not to leave the mould in the refrigerator for too long, as extended exposure to cold air can cause the wax to shrink too much and potentially crack. It is recommended to flip the mould every 30 minutes to ensure even cooling.
If you are working with a large number of candles, you can place them in a cooler room or cool the room they are in before demoulding. This will help speed up the cooling process without the risk of over-chilling the wax.
Once the wax has cooled and cured completely, you can begin the process of removing the candle from the mould. This may involve slowly loosening the mould from the wax by gently pulling it apart, or tapping on the bottom of the mould to shake the candle loose. With patience and efficiency, you will be able to successfully remove your candle from the mould without causing any damage.

Use a release agent or lubricant to prevent sticking
When making pillar candles, it's important to select the right type of wax for your project. However, you can also use a release agent or lubricant to prevent the candle from sticking to the mould. This will make it easier to remove the candle once it has cooled and solidified. Here are some options for release agents and lubricants:
Release Sprays
Release sprays 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 it's set. Not all release sprays are compatible with silicone moulds, so be sure to double-check before use.
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 it easier to remove the candle. Natural release agents like vegetable cooking oils work well in steel or plastic moulds and cause no mould erosion.
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. However, it's important to use the right amount of release agent, as too much can affect the appearance of the candle's surface.
Stearin
You can add up to 10% stearin to your candle wax to help prevent sticking. This additive hardens the wax and causes it to shrink slightly, allowing the candle to pull away from the sides of the mould and slide out easily.
Silicone Lubricant
If you're using a silicone mould, a non-stick silicone lubricant can be used to prevent sticking. This type of lubricant is colourless, odourless, and helps to ensure that your project doesn't stick to the mould.

Chill the wax to shrink it
It is important to wait for the mould to cool completely before attempting to remove the candle. This can take a few hours, but it is recommended to wait a full day before demoulding to allow the wax to fully harden and maintain its shape. If you try to remove the candle before the wax has set, the surface of the candle may tear and crumble.
Chilling the wax is an effective way to shrink it and make it easier to remove from the mould. Place the mould in a refrigerator to speed up the cooling process and help the wax set and separate from the mould. Flip the mould every 30 minutes to ensure even cooling. Do not leave the mould in the refrigerator for more than 10 minutes, as extended exposure to cold air can cause the wax to shrink too much and potentially crack.
If you have a large number of candles to remove, you can place them in a cooler room or cool the room they are in before demoulding. You can also put the mould in the freezer for five minutes if the candle is particularly difficult to dislodge.
The type of wax used also affects how easily a candle can be removed from the mould. Harder waxes, such as paraffin wax, beeswax, or pillar wax blends, tend to shrink away from the edges of the container as they cool, making them better suited for moulds. Softer waxes, like soy, coconut, or coconut apricot wax, tend to adhere to the edges and are more suitable for containers.
To prevent issues with stuck candles, it is recommended to warm up the candle mould before pouring the wax. This can be done by using a heat gun or placing the mould in a low oven. Pre-heating the mould helps to prevent issues with air bubbles and sinkholes, and it also allows the wax to cool down gradually.

Loosen the mould from the wax before removing
It is crucial to ensure that your candle has completely cooled and cured before attempting to remove it from its mould. The time required for this process varies depending on the type of wax used, so be sure to follow the manufacturer's instructions. Rushing this process can cause incomplete curing, resulting in soft spots, warping, or cracks in your candle.
Once your candle is fully cured and cooled, it's time to loosen the mould from the wax. Start by pressing the sides and bottom of the mould to help loosen the candle. The flexibility of silicone moulds makes this step easier. Avoid pulling or tugging on the wick, as this can damage both the candle and the mould. Instead, gently peel the mould away from the wax. Take extra time and caution with any areas that feel particularly resistant.
If you encounter resistance while peeling the mould away, you can try using a release agent or lubricant. Applying a thin layer of lubricant or mould release spray to the inside of the mould before pouring the wax can create a barrier that makes it easier to remove the candle later. Mineral oil, soy-based lubricants, and plant-based lubricants like olive oil are all common choices.
For intricate mould designs with delicate details, you may need to experiment with release slits. Cut a release slit around problem areas with a sharp blade or knife, then use duct tape to join it back together before pouring in the wax. When the wax is fully cured and cooled, start peeling the mould away from the release slit first.
To speed up the cooling process and help the wax separate from the mould, you can place the mould in the refrigerator. Ensure the mould has cooled to room temperature before refrigeration, and flip the mould every 30 minutes to ensure even cooling. Do not leave the mould in the refrigerator for more than 10 minutes, as extended exposure to cold air can cause the wax to shrink and crack.

Remove the candle over a soft surface
Removing a candle from its mould can be challenging, but with the right tools and techniques, it can be done flawlessly. Here are some detailed instructions for removing your candle over a soft surface:
Firstly, it is crucial to let the wax cool and cure completely before attempting to remove the candle from its mould. Patience is key here, as rushing this process can result in soft spots, warping, or cracks in your candle. Leave the mould on a flat surface while it cools, and refer to the manufacturer's instructions for specific curing times and temperatures for your chosen type of wax.
Once the wax has fully set, you can begin the process of releasing it from the mould. Start by slowly loosening the mould from the wax. Gently pull the mould apart just enough to break the contact between the mould and the wax. Take your time with this step, especially in areas that feel resistant.
Next, you can start peeling the mould away from the wax. This is where a soft surface comes into play. Place a pillow or another soft surface underneath the mould so that when you pop the candle out, it has a gentle landing and doesn't hit a hard table, which could cause dents or cracks. You can also try dipping the mould in a bowl of hot water to help loosen the wax, but be cautious as this could also melt the wax too much.
If your mould has intricate details or fragile components, consider using a release agent or mould release spray before pouring the wax. These products are designed to prevent the wax from sticking to the mould, making it easier to remove the candle without damage. However, be sure to choose a release spray that is compatible with silicone moulds.
Finally, if you're working with a stiff or custom mould, a flexible silicone mould is highly recommended. Silicone moulds can be stretched, turned inside out, or even cut on the side and sealed with a rubber band, making it easier to remove the candle without breaking it. Remember that practice makes perfect, and don't be discouraged if your first few attempts don't go as smoothly as expected!
