Gel candles are a unique type of candle that offers a longer burn time and a semi-transparent or opaque look. They are made from a blend of paraffin and beeswax, and gel candle wax is known to be more difficult to work with than traditional waxes. Making gel candles can be a fun DIY project, but it's important to be aware of common issues that may arise, such as tunnelling, mushrooming, and wet spots. To fix these issues, one may need to adjust the size of the wick, trim the wick, or gently heat the outside of the glass. This introduction will explore the process of making gel candles, the benefits of using gel wax, and how to troubleshoot common problems that may occur.

What You'll Learn
Choosing the right gel wax density
Gel wax is a combination of mineral oil and polymer resin. It is available in three densities, each with different characteristics. When choosing the right gel wax density, consider the following:
Scent
The density of the gel wax will determine the concentration of scent your candle can hold. Low-density gel wax can hold up to 3% fragrance, medium-density gel wax can hold up to 4%, and high-density gel wax can hold up to 5%. If you prefer a highly fragranced candle, opt for a higher density wax. However, keep in mind that fragrances with a flashpoint lower than 170°F can migrate out of the gel and cause problems.
Embeds
If you plan to embed objects in your gel candle, the density of the gel wax will determine what types of objects it can support. Low-density gel wax is not firm enough to support embeds in suspension and is better for candles with decorations that rest on the bottom. Medium-density gel wax can support lightweight embeds such as beads, small flowers, and glitter. High-density gel wax is firm enough to hold heavier embeds in suspension, such as metal charms, glass ornaments, and larger beads.
Colour
When colouring gel wax, it is recommended to use a liquid dye as wax-based dyes can cause the gel to become cloudy and make it difficult to achieve an even distribution of colour. Very little dye is needed to colour gel wax, and it is easy to over-colour gels.
Melting Point
The melting point of gel wax varies depending on its density. Low-density gel wax has the lowest melting point and is the easiest to melt, while high-density gel wax needs to be melted at a higher temperature. When melting gel wax, do not exceed 260°F as it could ignite at this temperature.
Cost
The cost of gel wax also varies with density. Low-density gel wax is the cheapest option, while high-density gel wax is the most expensive.

Adding colour and fragrance
Choosing the Right Colourant
When it comes to choosing a colourant for your gel candle, opt for liquid candle dye. Granular or powder dye can be used, but it may cause the gel to become cloudy. Liquid dye ensures colour longevity and can be easily mixed to create unique blends. Only a small amount is needed, and it can be added before or after pouring the wax, depending on the desired effect. If added before pouring, the colour will be evenly spread throughout all the layers, creating a monotone candle. Adding the colourant after pouring will create a swirling effect, and adding it once the gel is mostly cooled will create a ring around the top.
Selecting a Compatible Fragrance
When selecting a fragrance for your gel candle, choose a non-polar scent with a flashpoint above 170°F (76.6°C). Hydrocarbon-compatible fragrances are also suitable. Fragrance oils or essential oils can be used, and it's important to test them before adding them to the wax to ensure they mix well and don't cause discolouration. Natural ingredients like cinnamon and citrus are known to discolour wax, and synthetic components like vanillin can also cause discolouration over time due to oxidation. Test your fragrance by mixing one part fragrance with three parts mineral oil. If it mixes well, it should be safe to add to your gel wax.
Adding Fragrance at the Right Time
You can add fragrance to your gel candle before or after pouring the wax. If adding it before, heat the mixture until the scent blends with the wax. If adding fragrance after pouring, apply oil drops to the candle's surface. Always stir thoroughly to achieve an even distribution of scent.
Embeds and Decorations
You can also embed items within your gel candle to add texture and visual interest. Natural elements like dried flowers, leaves, or twigs can be used, as well as items like gemstones, marbles, beads, or figurines. These embeds can be added between layers of gel wax to create a visually striking effect. Just be sure to follow the proper temperatures and techniques for working with gel wax and always prioritise safety when working with hot wax and open flames.

Using the right wick
There are several types of wicks to choose from, each with its own unique properties and suitability for different types of candles. For example, cored wicks contain a wire core that helps the wick remain straight while the candle is being poured and when it is lit. These wicks are commonly used for gel candles and have been primed with standard wax. Another option is coreless, cotton braided wicks with paper filaments. These wicks are designed to bend at the tip, forcing the tip into the hottest part of the flame for more complete combustion and less smoke. They can also be used for gel candles.
Wooden wicks are a newer option, consisting of two identical pieces of wood pressed together. Softwood wicks are superior to hardwood wicks as they produce a unique crackling and popping sound when burned. They are ideal for natural waxes like soy and waxes with high fragrance oil content. When using wooden wicks with pure soy wax, it is recommended to use a larger wick size to ensure a wider melt pool, as soy wax tends to retain heat and fragrance.
The CD series of wicks is a popular choice among experienced candlemakers. These wicks are flat braided and have a special paper filament woven around them. The type of wick you choose will depend on various factors, including wax type, fragrance load, dye type, and container diameter. It is recommended to experiment with different wick sizes and styles to find the best match for your candle. Sampler kits are available to help with this process.

Avoiding bubbles
To avoid bubbles in your gel candles, there are several steps you can take during the candle-making process. Firstly, when melting your gel wax, use a low to medium flame if you're using a stove, or preheat your oven to a temperature of 225°F (107°C). Do not let the gel wax exceed 230°F (110°C). Using the correct temperature will help prevent bubbles from forming.
Secondly, when pouring the melted gel wax, do so slowly and carefully. The faster you pour, the more likely bubbles are to form. Only pour enough wax to cover the first section if you're working with layers. If bubbles do appear, use a hairdryer to reheat the top layer and eliminate them.
Additionally, choose the right type of dye for your gel candles. Avoid wax-based dyes, as they can make the gel cloudy. Instead, opt for liquid dyes specifically designed for gel candles. Also, be mindful of the amount of dye you use—it's easy to over-colour gels, and too much dye can affect the clarity of your candle.
Finally, select the appropriate wick for your gel candle. The higher burning temperatures of gel candles require a specific type of wick to ensure safety and proper burning. Follow the instructions and recommendations provided with your gel candle supplies to choose the right wick.

Cooling and setting
Once you've poured your gel wax into the mould, it's important to let it cool and set completely before moving or using your candle. This can take several hours or even overnight. To avoid cracking on the top of your candle, it's best to let it cool at a steady room temperature of around 18°C to 20°C. You can also pre-heat your candle vessel before pouring to help slow down the cooling process.
If you want to add multiple layers of gel wax, wait for the first layer to cool mostly before adding the second layer. This should only take a few minutes. You can adjust any embeds with tweezers at this point if they've moved under the pressure of the first layer. Repeat this process for as many layers as you wish to add.
If you notice unwanted bubbles forming on the top of your candle, use a hairdryer to gently reheat the surface and solve the problem. However, be aware that introducing too much air into the wax can turn it a milky white colour, so it's best to stir and pour very slowly to minimise bubbles.
Once your gel wax has cooled and set, you can enjoy your homemade candle!

Tunnelling occurs when the candle wick is too small and consumes more fuel than it can burn off. To fix this, increase the size of the wick until the candle burns as close to the edge of the vessel as possible.
