Cardboard is a cheap and easy material to use for making candle moulds. Candle makers often use mould release substances to prevent candle wax from sticking to the interior of the mould. However, when using cardboard as a mould, do you need to grease it first? Cardboard candle moulds can be made from toilet paper rolls, cereal boxes, or shoe boxes. To make a candle using a cardboard mould, candle wax is poured directly into the mould, so greasing the cardboard is not necessary.

What You'll Learn
Use vegetable oil as a natural release agent
Cardboard can be used as a functional and easy candle mould. When making candles, it is important to use a release agent to prevent the candle wax from sticking to the interior of the mould. This is a substance that acts as a barrier or lubricant, making it easier to remove the candle from the mould once it has cooled and solidified.
Vegetable oil can be used as a natural release agent. Oils act as a barrier between the wax and the mould, making it easier to remove the candle from the mould. To use vegetable oil as a release agent, simply apply a thin layer of oil to the interior of the cardboard mould before pouring in the wax. It is important to use the right amount of oil. Too much can affect the appearance of the candle's surface, and too little may not provide adequate release.
In addition to vegetable oil, other natural release agents can be used, such as coconut oil or mineral oil. Alternatively, you can use release sprays, which are aerosol sprays specifically designed for candle-making. These sprays create a thin, even layer of release agent on the mould's surface. Another option is to use a thin layer of melted paraffin wax as a release agent, which creates a barrier between the wax and the mould.
When making candles in cardboard moulds, it is important to ensure that the mould is stable and secure. This can be done by using hot glue to secure a toilet paper tube to a square base. It is also important to allow the glue to dry completely before pouring in the wax. Additionally, make sure that the wax is not too hot, as it can melt the glue and leak out of the mould.

Try a release spray for easy removal
Cardboard can be used as a candle mould, and it is easy to use. However, if you are using glue to seal the cardboard, make sure it is high-temperature glue, as regular glue may melt when you pour in the hot wax. Even with high-temperature glue, you may still encounter issues with the wax leaking out of the mould.
To avoid this problem, you can use a release spray, which will act as a barrier or lubricant to make it easier to remove the candle from the mould once it has cooled and solidified. 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.
Before using a release spray, it's a good idea to test it on a small area of the mould to ensure it works well with your specific mould and wax combination. You should also follow the manufacturer's instructions for how much release spray to use. Too much can affect the appearance of the candle's surface, and too little may not provide adequate release.
If you are having trouble finding a release spray, you can use a silicone spray or a baking spray instead. You can also use a thin layer of melted paraffin wax brushed onto the interior of the mould as a release agent.

Use wax as a mould release
When making candles, it is important to use a mould release to prevent the candle wax from sticking to the interior of the mould. This is especially important when using cardboard candle moulds, as the wrong type of glue can melt when hot wax is poured in.
Mould release wax is a traditional and commonly used release agent in resin casting and composites. It can be used on its own or in conjunction with other release agents, like oils, to create a barrier that prevents the candle wax from adhering to the mould. This helps to prevent damage to the finished candle and makes the demoulding process smoother.
To use wax as a mould release, start by ensuring that the mould surface is properly sealed, clean, and free of contaminants. Using a clean, lint-free cloth, collect a small amount of wax and apply it to the surface of the mould in small circular motions. Pay particular attention to covering the entire surface, especially any tight corners. Allow the wax to dry, which will cause its appearance to 'matt off' slightly, making the swirls more apparent.
Using a different, clean, lint-free cloth, gently skim the cloth over the surface of the mould to smooth out the swirl pattern of the wax. Keep the pressure very light, as you want to polish the wax, not remove it. Repeat the application of the wax about three more times, each time following the same procedure, until the surface of the mould looks completely swirl-free and shiny.
It is important to note that using too much wax can affect the appearance of the candle's surface, while using too little may not provide adequate release. Therefore, it is recommended to test the wax release on a small area of the mould before proceeding. Additionally, wax mould releases may not be ideal for intricate mould surfaces with narrow areas, as they can be difficult to apply evenly and may leave bare spots. In such cases, a mould release spray may be a more suitable alternative.

Don't use glue sticks, they'll melt
When making candles, it is important to ensure that the wax does not stick to the interior of the mould. This can be done by using a mould release agent, such as release sprays, oils, or paraffin wax. Cardboard can be used as a functional and easy candle mould.
However, when using cardboard as a candle mould, it is important to avoid using glue sticks to seal the bottom of the mould to another piece of cardboard. This is because the hot wax poured into the mould can melt the glue, causing it to leak out. To prevent this issue, it is recommended to use high-temperature glue or hot glue instead of glue sticks. High-temperature glue can withstand temperatures up to 350-410 degrees Fahrenheit, which is significantly higher than the melting point of candle wax.
Glue sticks, on the other hand, typically have a lower melting point. Low-temperature glue sticks, for example, melt around 250-260 degrees Fahrenheit, which is within the range of temperatures at which candle wax is heated. Therefore, when using a glue stick to seal a cardboard candle mould, it is important to opt for a high-temperature formulation to avoid melting.
Additionally, it is worth noting that even with high-temperature glue, it is crucial to allow the glue to dry completely before pouring in the wax. This can take several hours, depending on the ambient temperature and humidity. By taking these precautions, you can avoid the issue of melted glue and create a stable and secure cardboard candle mould.

Cardboard is a functional, easy-to-use mould
Cardboard is a functional and easy-to-use mould for candle-making. It is a cheap and versatile material that can be used to create candle moulds of various shapes and sizes. Cardboard tubes, such as toilet paper rolls, can be used as a base for cylindrical candles, while cardboard boxes, such as cereal or shoe boxes, can be cut and rolled into cylinders to create moulds for pillar candles.
To create a cardboard candle mould, start by measuring the desired height of your candle and cut a piece of cardboard slightly longer than that measurement. Roll the cardboard into a tight and smooth cylinder, securing it with tape. Cut a circle of cardboard slightly larger than the cylinder's diameter and cut a small hole in the centre for the wick. You can use a toothpick or a skewer to make the hole. Secure the wick in place with tape or glue, then attach the circular base to one end of the cylinder.
It is important to use high-temperature glue or a hot glue gun when assembling cardboard candle moulds to prevent the glue from melting when the hot wax is poured in. Allow the glue to dry completely before pouring in the wax. You can also use a mould release agent, such as vegetable oil, coconut oil, or mineral oil, to coat the interior of the mould and make it easier to remove the candle once it has set.
Cardboard moulds are easy to use and can be customised to create candles of different sizes and shapes. They are a great option for making container candles or floating candles, and you can add colour, fragrance, and decorations to personalise your creations. Cardboard is readily available and can be upcycled from household items, making it a sustainable and cost-effective choice for candle-making enthusiasts.
