Selecting a model to replicate

When selecting an object to use as a model, it is important to consider how easily it can be removed from the silicone mold after it has cured. Complex shapes with intricate details, such as a perfume bottle with flowers, may be challenging to extract without damaging the mold. Therefore, opting for objects with simpler shapes that can be effortlessly pulled out of the silicone is recommended.

For hollow models, it is necessary to fill them with materials like wood and clay to create a solid candle. It is important to ensure that the clay surface is smooth so that the mold rubber can accurately capture all the details of the model. Additionally, creating a hole in the bottom board of the mold box can help hide any protrusions on the model that are not desired in the final candle.

The model should be securely adhered to the bottom board of the mold box to prevent it from floating when the mold rubber is poured. A fast-setting epoxy adhesive, such as PolyPoxy® Quick Stick Adhesive, can be used for this purpose. It is essential to allow adequate curing time before proceeding to the next steps.

In summary, selecting a model to replicate involves choosing an object with an appealing shape that can be easily removed from the mold. Candle makers can sculpt their models or use computer-based design options. Preparing the model by filling hollow spaces, creating a smooth surface, and adhering it securely to the mold box are crucial steps in ensuring the successful replication of the chosen design.

Preparing the wax

Choosing the Right Wax

The type of wax you choose will depend on the mould you are using and the desired characteristics of your candle. Soy wax is a popular choice due to its eco-friendliness, pleasant scent, and low melting point, which reduces the risk of damaging the mould. Rapeseed wax is another option, particularly useful for small, intricate designs as it doesn't break when unmoulding. For scented candles, beeswax is a good option, as it holds scents well and allows for intricate details. If you want to add colour to your candles, consider using palm wax, as soy and rapeseed waxes don't always work well with excessive colouring.

Melting the Wax

When melting your wax, use a bain-marie for even melting. Be cautious not to overheat the wax, as this can cause it to stick to the mould. Use a thermometer to monitor the temperature, and aim for a slightly cloudy but still liquid consistency.

Testing Colour and Scent

Before pouring the wax, test its colour by pouring a small amount into a container of cool water. The wax will quickly harden, allowing you to assess if more dye is needed. When adding a scent, be mindful that adding it too early will cause it to dissipate. Add the scent after the wax has melted, and be cautious not to add too much to avoid excess smoke and potential ignition of surface oils.

Pouring the Wax

When pouring the wax into your mould, fill it right to the top. This is crucial, as not filling it enough will make it difficult to release the candle from the mould later. Pour slowly and evenly, keeping the spout close to the mould to avoid creating air bubbles.

Cooling and Demoulding

Allow the wax to cool at room temperature, or place it in a refrigerator for a short period to help the wax contract and release more easily. The cooling time will depend on the size of your mould, so be patient. Once the mould is completely cool, gently pull on the wick to release the candle. If the candle is stuck, press around the mould to help break the seal.

Remember to always clean your mould before use and consider using a release agent to ensure your candle pops out easily. With the right wax preparation, you'll be well on your way to creating beautiful, smooth candles.

Pouring the wax into the mould

Now that you've created your candle mould, it's time to pour in the wax. Here are some detailed, step-by-step instructions to guide you through the process:

Preparing the Wax:

Before you begin pouring, it's crucial to prepare your wax properly. You can use paraffin wax, soy wax, or beeswax, which you can easily find in craft stores or online. If you want to add colour to your candles, this is the stage to do it. Use a wax thermometer to ensure the wax isn't too hot before adding it to the mould. The ideal temperature for pouring wax is around 170°F to 180°F (82°C), but always refer to the mould instructions as different brands may have specific recommendations.

Setting Up the Mould:

Before pouring the wax, set up your mould by attaching the wick securely. Cut the wick at the base, leaving about 1 inch (2.5 cm) of length. Use wire to hold the wick taut and centred in the mould. If your mould has a removable base, consider removing it before adding the wax to avoid any mess.

Pouring the Wax:

Carefully pour the melted wax into your prepared mould. Go slowly to avoid any spills or overflow. As the wax cools, it may cave in, so it's a good idea to have some extra wax on hand to top it up if needed.

Final Steps:

Once you've poured the wax, you might want to add a small stick or toothpick to the bottom of the candle if you plan to use it on a cake, so it can stand upright. Keep in mind that the wax will have a flat back once it sets. Allow the wax to cool completely, which may take some time, and then you can remove it from the mould. Your candle is now ready for use, and you can reuse your mould to create more candles!

Using a silicone mould

Selecting a Model

Firstly, you need to decide on a model to replicate with your candle. This can be something small and simple, especially if it is your first attempt. Many people use 3D printed models, or you can sculpt your own design with clay, wood, or wax.

Preparing the Mould

Prepare your workspace by constructing a base for the mould. This can be made from wood, plastic, or foil. Attach your chosen model to the base using a strong adhesive, ensuring an even coat of glue to prevent silicone from seeping through. If using a porous material like wood, seal it before attaching the model.

Mixing and Pouring the Silicone

Follow the manufacturer's instructions for dispensing the silicone rubber. You can use the ''Double Mix and Pour Technique' to ensure the silicone is well mixed. Pour the mixed silicone over the model, allowing it to flow around the model in the mould container.

Curing and Demoulding

Allow the silicone to cure for several hours. The exact time will depend on the type of silicone used. After curing, carefully demould the rubber mould by removing the plastic mould box and the model inside. You may need to trim any excess rubber from the base of the mould.

Preparing the Wax and Wick

Prepare your wax by melting it in a double boiler or a heat-safe metal measuring cup placed in boiling water. Wear protective gloves to handle hot equipment. You can add colours and scents to your wax by mixing them in paper cups. Once you have your desired colour and scent, carefully pour the hot wax into your silicone mould. Place the wick in the mould, holding it in place with a clothespin or threading it through a hole in the mould.

Final Steps

Allow the wax to cure for several hours. The exact time will depend on the type of wax and the complexity of your candle shape. Once cured, slowly stretch out the edges of the mould and gently push the bottom to loosen the candle. Continue to carefully unravel the mould until the candle is separated. Trim the wick to the desired length, and your candle is ready!

Creating candles with silicone moulds offers endless possibilities for shapes and designs, making it an enjoyable and creative process.

Removing the candle from the mould

Next, you can begin to unmould your candle. If you've used a simple mould, you may be able to simply pull the candle out. However, if your mould is more complex, you may need to carefully cut the mould away from the candle. For example, if you've used a silicone mould, you can carefully cut the silicone in a straight line from the top to the base of the mould and then slowly peel the silicone away.

If you've used a wooden or waxy model inside your mould, you'll need to remove this first. For instance, if you've used a wooden dowel, simply pull it out from the mould. If your model is adhered to the base, ensure that you remove this carefully so as not to damage the candle.

Finally, trim any excess material from the candle, such as leftover wax or bits of the mould. You can use a toothpick or a small stick to help with this process.
