Essential oils are highly sought after in candle-making due to their natural fragrances and positive influence on mood and well-being. They are made from pure plant extracts, which are distilled or otherwise extracted from various parts of the plant. When choosing essential oils for candles, it is important to consider the type of wax, wick, and container used, as these factors impact the candle's burn and aroma distribution. Soy wax is a popular choice for essential oil candles as it is easy to use, non-toxic, and burns cleanly. A smaller wick is generally recommended to prevent the oil from burning off too quickly. To create unique fragrances, essential oils can be blended in different ratios, combining complementary scents, playing with opposites, or creating seasonal vibes. It is advisable to use high-quality, pure essential oils to ensure the aroma lasts throughout the candle's burn. Popular essential oils for candles include lavender, peppermint, citrus, and lemon.

What You'll Learn
Choose a wax with a high flash point, like soy or beeswax
When making candles with essential oils, it is important to choose a wax with a high flash point. Essential oils have lower flash points than synthetic fragrance oils, meaning they require less heat to release their aroma. However, this can also cause them to evaporate at high temperatures, limiting their strength.
Soy wax is an excellent option for creating long-lasting, beautifully scented candles with essential oils. It is easy to use, non-toxic, and produces a clean, even burn with minimal soot. Soy wax flakes are a good choice for beginners. Beeswax is another natural alternative, which burns cleanly and has a subtle honey-like aroma. However, beeswax is not a vegan option, and it can be more expensive.
The flash point of a candle fragrance oil is the temperature at which it becomes combustible if exposed to a spark or flame. While this is generally only important for those making gel candles, it is crucial to ensure safety during the candle-making process. Fragrance oils with low flash points can be safely added to hot melted wax, but it is important not to leave the mixture on a heat source for too long, as this can weaken the scent. Additionally, it is important not to overload the wax with too much fragrance oil, as this can create a dangerous situation if the fragrance leaks from the curing wax and is heated beyond its flash point.
By choosing a wax with a high flash point, such as soy or beeswax, you can ensure that your essential oil candles will burn safely and effectively, maximizing the scent and creating a long-lasting, beautifully scented candle.

Select a small cotton or wood wick to prevent tunneling
When making candles with essential oils, it's important to select the right wick to prevent issues like tunneling. Tunneling occurs when the heat is unable to reach the entire surface area of the candle, causing the wax to stick to the sides of the container while only the centre melts. This can be prevented by choosing a small cotton or wood wick.
Cotton wicks are made from tiny cotton fibres twisted together and cured with wax to create a single thread. They produce a tall flame at the tip and have a higher paper-to-cotton ratio, which helps to create an even heat ratio and a smooth melt pool. Cotton wicks are also easy to care for, requiring simple trimming to ensure they are ready to light.
Wooden wicks, on the other hand, are made from precisely cut slabs of wood that are reinforced with a smaller strip of wood down the middle for structural integrity. They typically burn lower and smoulder over time, helping to warm the wax and release the aroma evenly. Wooden wicks may require more effort to trim, as they solidify after cooling down, and there can be some variation in quality.
Both types of wicks will produce enough heat to melt soy wax candles, but cotton wicks are generally considered more consistent and easier to work with for beginners. However, some people prefer wooden wicks for their unique crackling sound and sustainable, handcrafted qualities.
To prevent tunneling, it is recommended to use a smaller wick, especially when working with essential oils, as they require less heat to release their aroma effectively. Additionally, choosing a narrow container can further help prevent tunneling by ensuring an even and long-lasting burn.

Pick a heat-resistant container, like a glass jar or enamel cup
When making candles with essential oils, it is important to choose a heat-resistant container. Glass jars and enamel cups are ideal choices as they are durable and less prone to cracking compared to other options, such as wine glasses. These containers are widely available, easy to use, and typically reliable.
Glass mason jars, for instance, are a popular option for candle-making as they are heat-safe and can withstand high temperatures without cracking or breaking. They are also versatile and can be used to create a variety of candle shapes and sizes. Enamel cups are another excellent choice for heat resistance, and their durability makes them ideal for candle-making. These cups are often made with a thick layer of enamel, which provides an extra layer of protection against heat.
When selecting a container, it is crucial to consider the size and shape that will best suit your candle-making needs. For example, a narrow container is recommended when using a smaller wick to prevent "tunnelling," where wax sticks to the sides of the container. Consulting a wick supplier can help determine the appropriate container circumference for your specific wick.
Additionally, it is important to ensure that your chosen container is safe for candle-making. While glass and enamel are generally heat-resistant, it is always good to check with the manufacturer to confirm their suitability for candles. This will help create safe and effective essential oil candles.
By choosing heat-resistant containers like glass jars or enamel cups, you can ensure a safe and successful candle-making process while also allowing for various design options to personalise your candles.

Opt for pure, natural essential oils with strong aromas
When choosing essential oils for candles, it is important to opt for pure, natural essential oils with strong aromas. Essential oils are derived from plants and are considered "natural" fragrances. They undergo an intensive manufacturing process to extract the oil, which results in a highly concentrated and pure product.
Using pure, natural essential oils is important because it ensures that the aroma of your candle will last as long as the candle burns. Essential oils with strong aromas, such as those with higher flash points (above 150°F), are more likely to retain their scent when exposed to heat. This is because essential oils have low flash points, causing them to evaporate at high temperatures and limiting their strength.
Additionally, pure essential oils are often used in aromatherapy to improve physical, emotional, and spiritual well-being. They can positively influence your mood and provide comfort, helping to create a calming and relaxed atmosphere.
Some popular essential oils for candle-making include citrus, lemon, lavender, tea tree, and ylang-ylang. These oils offer a wide range of scents and can be blended to create unique and complex fragrances.
However, it is important to note that not all essential oils are safe for candles. Some essential oils, such as cinnamon, clove, and lavender, can release potentially toxic compounds when heated to high temperatures. Therefore, it is crucial to choose essential oils with strong aromas that are also suitable for candle-making.

Blend oils at the right temperature to create your desired scent
Essential oils are very sensitive to temperature, and they can easily evaporate if the heat is too high. To avoid this, it is important to blend them at the right temperature to create your desired scent.
When making candles with essential oils, it is recommended to use a thermometer to monitor the temperature of the wax. For soy wax candles, add essential oils when the melted wax cools down to around 60°C (140°F). For beeswax, paraffin, and gel wax candles, a higher temperature creates a stronger blend, so aim for around 70°C (158°F-160°F).
It is important to note that adding essential oils to wax that is too cold can also affect the blend. If the wax is still liquid but too cold, the essential oils may not mix properly, resulting in an uneven distribution of scent in the candle.
The ideal temperature range for adding fragrance oil to wax is between 185°F and 200°F (85°C - 93°C). This ensures that the oil blends safely and consistently throughout the wax.
Additionally, consider choosing essential oils with higher flash points (above 150°F) and strong aromas. This will help maximize the scent and effectiveness of your essential oil candles.
