What You'll Learn
Choosing the right wax
Type of Wax
Different types of waxes are available for candle making, each with unique properties. Commonly used waxes include paraffin, beeswax, palm wax, soy wax, rapeseed wax, olive wax, and coconut wax. Paraffin wax is a popular choice due to its ability to create shiny candles and its compatibility with colouring and scenting. However, it is derived from petroleum, which may be a concern for some. Vegetable waxes, such as rapeseed wax, offer longer burn times and shorter drying times compared to paraffin. Soy wax is another widely used option, but it tends to be brittle for small candles and may not be suitable for pillar candles unless specifically designed for them.
Melting Point
Consider the melting point of the wax, especially if you plan to use a silicone mould. Harder waxes with higher melting points, such as those above 140°F, are generally better for moulded candles as they retain their shape during burning. Softer waxes with lower melting points may be challenging to remove from the mould and may not hold their form as well.
Mould Compatibility
Certain types of waxes work better with specific mould materials. For example, beeswax is ideal for silicone or latex moulds, as it provides superb detail and flexibility during the unmoulding process. If you're using a polycarbonate mould, its heat resistance makes it suitable for waxes with higher melting points. Plastic moulds, on the other hand, have lower heat resistance, so you'll need to choose a wax that doesn't require extremely high temperatures.
Colour and Scent
If you plan to add colour or scent to your candles, choose a wax that is compatible with these additions. Paraffin wax is excellent for mass colouring, while vegetable or animal waxes can be tinted but may impact the candle's burning if the colour is too dark. When it comes to scent, remember that only the wax on the surface of the candle will diffuse the fragrance effectively.
Shape and Size of the Candle
The type of wax you choose should also consider the shape and size of the candle you want to create. Harder waxes are better for intricate details and free-standing candles, while softer waxes may be more suitable for basic shapes or candles that will be contained within a jar or container.

Selecting a mould
There are two popular types of candle moulds: metal and silicone. Metal moulds are ideal for basic shapes with smooth sides and are durable and inexpensive. They work well with high-melting-point waxes, such as paraffin, beeswax, palm wax, and certain types of soy wax. If you're using a metal mould, make sure your wax has a minimum melting point of around 140°F to ensure it can hold its form while burning. Harder waxes are better suited for metal moulds than softer waxes meant for containers.
Silicone moulds, on the other hand, are high-end options that produce highly detailed candles. They are typically used with beeswax or rapeseed wax. Silicone moulds are flexible, making it easier to remove the candle by gently pulling on the mould and wriggling the candle out. However, for long or tall candles, you may need to cut the mould. Don't worry, as silicone moulds are durable and can be easily repaired with rubber bands.
Latex moulds are another option that allows for original shapes, although they are not recommended for use with stearin. Polycarbonate moulds are heat resistant up to 120°C and are transparent, making them ideal for colouring. Plastic moulds, however, should be avoided as they melt at relatively low temperatures, around 60°C.
When selecting a mould, consider the type of wax you plan to use and choose a mould that is suitable for that wax. For example, extremely soft waxes like some soy waxes and coconut wax can be difficult to remove from certain moulds. Rapeseed wax is a good option for small, detailed candles as it is less brittle than soy wax. If you want to create coloured candles, palm wax is a better choice than soy or rapeseed wax.

Preparing the mould
Selecting the Right Mould
The type of mould you choose will depend on the wax you plan to use and the shape of the candle you want to create. Metal moulds are ideal for basic shapes with smooth sides, and they are durable and affordable. Silicone moulds, on the other hand, are high-end and suitable for intricate designs, but you may need to cut them to remove the candle easily, especially for long or tall shapes. Latex moulds offer the ability to create original shapes, but they are not recommended for use with stearin.
Preparing the Surface
Before pouring the wax, it is essential to prepare the inside of the mould. Apply a thin coat of oil to the mould's surface, ensuring that you cover it evenly. If your mould has a removable base, remove it before oiling to avoid getting oil on the wick. This step will make it easier to remove the candle once it has set.
Inserting the Wick
Cut the wick to an appropriate length, leaving about 1 inch (2.5 cm) protruding from the base of the mould. If your mould has a removable base, fit it back on before proceeding. Use a wire to hold the wick taut and centred within the mould. Ensure the wick is straight and secure, as this will affect the final appearance of your candle.
Temperature Considerations
Different types of wax require specific temperatures for optimal results. Paraffin wax, for instance, should be heated to around 185°F (85°C) to achieve a shiny finish. If you are using soy wax, it is recommended to choose a variety specifically designed for pillar candles and moulds, as regular soy wax tends to be too soft for this purpose. Harder waxes generally perform better in moulds than softer varieties.
Additional Tips
If you want to add colour to your candle, consider using dry dye chips as they offer more control over the intensity. You can also scent your candle, but keep in mind that only the surface wax will significantly impact the room's fragrance. Always choose the right type of wick for your candle, as a wick that is too thick will produce excessive smoke.

Pouring and setting
When pouring the wax, ensure your wick is in place and held taut by a wire in the middle of the mould. The wax should be heated to at least 140°F, though some sources recommend 185°F for paraffin wax to achieve a shiny finish. You can add dyes or fragrances at this stage, though be aware that vegetable or animal waxes with significant colouring may burn less effectively.
Once the wax is heated and any additional ingredients are mixed in, pour it carefully into your mould. You can place the mould in a cool water bath to help it set and create a shiny finish, but be careful not to get the wick wet.
After the wax has hardened, you can remove the candle from the mould. Metal and silicone moulds are popular options, with metal being more durable and better for basic shapes, and silicone being more flexible and suitable for intricate designs. If you're using a silicone mould, you may need to cut it to remove the candle, especially for long or tall candles. Simply make a single cut straight down about two-thirds of the mould, and hold it together with rubber bands when pouring in the wax.
If you're having trouble removing the candle, try putting the mould in the freezer for at least 10 minutes. Once the candle is out, trim the wick, and your candle is ready!

Removing the candle
Firstly, it is important to select the right type of wax and mould. Harder waxes, such as paraffin, beeswax, palm wax, or specific types of soy wax designed for pillar candles, are ideal for moulded candles. These waxes can better retain their shape when removed from the mould and during burning. Softer waxes, like coconut wax, are not recommended as they can be challenging to remove from the mould. Choosing a suitable wax is essential to ensure your candle comes out of the mould smoothly.
The type of mould you use also matters. Metal moulds are perfect for basic shapes and smooth sides, while silicone moulds offer more flexibility and can be used for intricate designs. Latex moulds allow for original shapes, but they don't work well with stearin.
Now, let's discuss the steps to remove the candle:
- Allow the wax to harden completely. You can place the mould in a cool (not cold) water bath to speed up the hardening process without wetting the wick.
- Gently remove the bottom of the mould, if it has a removable base.
- Push the candle out of the mould. For silicone moulds, you can gently pull on the mould and wiggle the candle out, especially if it's a small mould. For longer or taller candles, consider making a single cut straight down about 2/3 of the mould before attempting to remove the candle.
- If the candle doesn't come out easily, don't force it. Instead, place the mould in the freezer for at least 10 minutes. This will help the wax contract slightly, making it easier to remove.
- Once the candle is out, trim the wick as needed.
Remember, the key to successful removal is using the right combination of wax and mould. With the proper techniques and a bit of patience, you'll be able to effortlessly remove your candle from its mould.
