Candle casting is a centuries-old craft that has been used to create candles for both decorative and spiritual purposes. The process involves melting wax and pouring it into a mould, with various techniques and materials that can be used to create unique candles. Candle casting can be an eco-friendly practice, as it allows for the reuse of old wax and the creation of custom, handcrafted products. To get started, candle-makers will need a few basic supplies, such as wax, wicks, moulds, and a heat source. The type of wax and mould can vary depending on the desired outcome, and additional materials such as essential oils, dyes, and fragrances can be added to create scented and coloured candles. With a little practice and creativity, anyone can learn the art of candle casting and enjoy the warm and welcoming atmosphere it brings to their home.

What You'll Learn
Choosing a mould
One popular method is to use sand as a mould. Sand is a versatile and inexpensive choice, allowing you to create an infinite number of do-overs. To make a sand mould, dampen the sand so it clumps together when squished in your hand. Add the sand to your container, pressing it flat, and set your desired shape into the sand. Then, carefully remove the shape, leaving an impression in the sand. You can also use sand to create unique designs, such as ombre or striped patterns.
Another option is to use silicone putty, such as Sugru, to create detailed moulds. This method is great if you want to make intricate shapes, like Lego minifigures. You can either use the Sugru mould directly or create a wax mould first and then use the 'lost wax process' to create a second mould for casting.
You can also purchase ready-made candle moulds in various shapes and sizes from online retailers like Amazon and Etsy. These moulds are typically made of materials like silicone, which allow for easy removal of the final candle product.
When choosing a mould, consider the size and shape of the candle you want to create. If you're making a candle that is larger at the bottom than the top, you'll need to make it upside down. Additionally, larger-diameter candles are generally easier to make and safer to burn than narrow ones.
Lastly, remember to prepare your mould properly before pouring in the wax. This may include oiling the inside of the mould or ensuring the sand is well-compressed and damp enough to hold its shape.

Preparing the wax
Choosing the Right Wax
The first step is to choose the type of wax you want to work with. Commonly used options include paraffin wax, soy wax, and beeswax. Paraffin wax is a popular choice for aromatherapy due to its excellent scent throw and ability to hold fragrances without compromising burn quality. Soy wax is another easily accessible option, as it comes in the form of flakes or pastilles that can be scooped and weighed.
Melting the Wax
Once you have selected your wax, it's time to melt it. Start by placing the wax in a melting pot or a double boiler. If using a double boiler, fill the bottom pot with about an inch of water and place the pouring pot inside. Adjust the heat to a medium-low setting to maintain a gentle boil. Ensure that the wax is never left unattended, and periodically check the temperature to prevent overheating.
Preparing the Molds
Before pouring the melted wax, it's essential to prepare your molds properly. Clean the molds with soap and water to remove any dust or old wax buildup. Next, apply a thin layer of a release agent, such as petroleum jelly, to ensure the candles can be easily removed once they have set. Seal the mold bottoms with tape or hot glue to prevent any wax leaks. It's also a good idea to test the molds for leaks using water or a small amount of wax before pouring.
Adding Colour and Scent (Optional)
If you wish to add colour and scent to your candles, this is the stage to do so. Always start with small amounts of dye and essential oils, gradually increasing as needed. Remember that too much dye or oil can affect the candle's burn quality. You can also add UV stabilizer at this point to prevent the colour from fading due to UV exposure. Mix everything thoroughly for 3 to 5 minutes and adjust the temperature to ensure the mixture is between 175°F and 185°F.
Pouring the Wax
Finally, it's time to pour the wax into your prepared containers or molds. Ensure that your containers or molds are at room temperature before pouring. Pour the wax slowly and evenly, keeping the spout close to the mold to avoid the formation of bubbles. Tap the mold gently after pouring to release any trapped air pockets, ensuring a smooth and bubble-free candle.

Adding colour and fragrance
To add colour to your candles, you can use either liquid dye or dry dye chips. Dry dye chips give you more control over the intensity of the colour, but both work well. You will need to stir the dye into the melted wax before pouring it into your mould. It's important to note that the final colour of the wax after it has set will always be a little different from what you start with, so you may need to experiment to get the desired shade.
When it comes to fragrance, essential oils are the key component. Choose high-quality, natural, pleasantly scented essential oils that are suitable for candle-making. You can select oils based on their desired scent experience, such as soothing lavender, refreshing lemon, exotic sandalwood, or aromatic cinnamon. Add the essential oils to the melted wax before pouring it into your mould.
You can also add fragrance to your candles by using leftover wax from previously used candles. First, collect the leftover pieces of wax and melt them down. This method allows you to create unique candles by mixing different colours and types of wax. However, make sure to remove any wicks and wick holders from the wax residue before heating it, and sieve out any foreign objects or residue to ensure a clean final product.
Additionally, you can add layers of colour to your candles to create an ombre effect. For example, you can start with one drop of white and four drops of blue for the first layer, then adjust the ratio for each subsequent layer to create a gradient.
By choosing specific colours and fragrances, you can also use your candles for manifestation purposes in candle magic. For example, green candles are associated with wealth, luck, and fertility, while pink candles represent self-love, friendship, and romance.

Setting the wick
When making your homemade wick, you need to decide how thick and long you want it to be. Small candles only need single wicks, while medium candles require a wick made from three strands of twine braided together. For a single wick, measure and cut the twine to be three inches longer than the height of your candle. If you plan to braid your wick, cut three equal lengths of twine that are four inches longer than the height of the candle.
To make a wick, you can use heavy cotton butcher's twine, pipe cleaners, or cotton string. If using twine, submerge it in a Borax solution and let it soak for 24 hours. If you're using a pipe cleaner, trim it to fit inside your candle container, then dip it into the melted wax and let it dry. If you're using cotton string, dip it into the melted wax and let it dry.
Once your wick is ready, it's time to insert it into the candle. If the wax has hardened, warm it slightly to soften it before inserting the new wick. Make sure the wick is straight and that the flame will not touch any flammable objects when you relight the candle.
To perform a combustion test, light the candle and observe the flame to see if it burns evenly and if the wax melts evenly. If the flame flickers or the wax does not melt evenly, this may be a sign that there is a problem with your wick choice.

Trimming and finishing
Step 1: Prepare your candle
Before you begin trimming the wick, ensure that your candle has cooled completely and that the wax has hardened. This will prevent the wick from bending or breaking during trimming. Allow at least 30 minutes after burning for the candle to cool before trimming.
Step 2: Measure the wick
Hold your wick trimmer or scissors above the candle and measure the length of the wick. A good rule of thumb is to trim the wick to 1/4 inch or 6mm in length.
Step 3: Trim the wick
Use your wick trimmer or scissors to cut the wick to the desired length. Make sure to cut the wick straight across to ensure an even burn. If you don't have a wick trimmer, scissors are the next best option. They can work well for cotton wicks, but it might be difficult to cut through wooden wicks.
Step 4: Remove the wick debris
Use a tissue or a small brush to remove any debris or trimmed wick from the candle. This is an important step to ensure a clean and even burn.
Step 5: Light your candle
Now that your candle is trimmed and free of debris, you can light it and enjoy!
Additional Tips:
- Regular wick trimming will not only improve the performance of your candle but also help it last longer.
- If you notice your candle is smoking visibly, it's a sign that you need to trim the wick.
- If you accidentally cut your wick too short, you can try a method suggested by Aisha Cort, the founder of VELA NEGRA Candles: "First, you can light the candle and let it burn for about 30 minutes to melt the wax pool. Once the wax pool is melted, you can extinguish the flame and dispose of the melted wax. Then, allow your candle to fully cool before relighting it."
