Creating a scented candle involves more than simply adding a fragrance to wax. The type of wax, the wick, the container, and the temperature all play a role in determining the strength of the scent, or throw, of a candle. The process of making a scented candle begins with selecting the right wax and fragrance combination, as well as determining the appropriate ratio of fragrance to wax. The type of fragrance used, such as essential oils or fragrance oils, will also impact the overall scent of the candle. Once the wax has melted, the fragrance can be added, and the mixture is then poured into a heat-safe container with a wick. The size of the wick and the container will also affect the candle's scent throw. Finally, it is important to monitor the temperature throughout the process to ensure the candle sets properly and the fragrance is not compromised.

What You'll Learn
Choosing the right wax
Type of Wax
The most common types of wax used for candle-making include paraffin wax, soy wax, beeswax, and coconut wax. Each type has unique properties and compatibility with fragrances:
- Paraffin wax holds scent the best among all types, but it is derived from petroleum and can release chemicals and soot when burned. It is important to note that paraffin wax has a lower melting point than other waxes, so adding fragrance at the right temperature is crucial to avoid compromising the scent.
- Soy wax is a natural alternative that works well with fragrance oils. It has a higher melting point than paraffin wax, and you should add fragrances when the wax cools down to around 140°F (60°C).
- Beeswax has a natural honey scent, but it may not hold additional fragrances as effectively as soy wax. If you decide to use beeswax, add fragrances while the wax is melting, but be aware that the results may vary.
- Coconut wax is another natural option that can be used in blends with other waxes, such as soy wax, to create a premium candle experience.
Fragrance Compatibility
When choosing a wax, consider its compatibility with your desired fragrance. Some waxes, like paraffin, can accommodate a higher percentage of fragrance (up to 12%), resulting in a stronger scent throw. Soy wax typically holds up to 10% fragrance, while beeswax may be less predictable in terms of fragrance load. If you plan to use essential oils, keep in mind that they often create a weaker scent than fragrance oils, and you may need to experiment to find the right ratio.
Container Size and Wax Amount
The size of your candle containers will determine the amount of wax needed. A helpful tip is to fill the container with water and then pour it into a measuring cup to accurately determine the volume. This ensures you use the right amount of wax and fragrance without wasting any materials.
Wick Considerations
The type and size of the wick you choose will depend on the wax brand, container size, and fragrance used. Different waxes have varying melting points, affecting the temperature at which the candle burns. Ensure you select a wick suitable for your chosen wax to avoid issues with burning across the full diameter of the candle. Manufacturers often provide sizing charts to help you determine the appropriate wick size.

Selecting a fragrance
Firstly, it is essential to understand the different types of fragrances available. Fragrance oils are commonly used in candle-making and can be found in various scents. These oils are designed to be added to melted wax and have a flashpoint, the temperature at which the oil becomes combustible. It is recommended to use fragrance oils with a flashpoint above 175°F (79.4°C) to avoid fire hazards.
Another option is essential oils, which are natural and can be used to create custom blends. However, essential oils can be trickier to work with and often result in a weaker scent. If using essential oils, it is recommended to start with a ratio of 1 ounce of oil per 1 pound of wax and then adjust as needed.
The strength of the fragrance is another important consideration. The amount of fragrance added to the wax will determine the scent throw, which refers to the strength of the scent when the candle is burning (hot throw) and when it is unlit (cold throw). Generally, store-bought candles contain an average of 6% fragrance, while premium candles can have up to 10%. To achieve a strong scent, it is recommended to use between 6 to 10% fragrance in the wax mixture.
Additionally, the type of wax used can impact the fragrance load. Different waxes have varying abilities to hold fragrance, with soy wax being a popular choice as it can hold up to 10% fragrance. Beeswax, on the other hand, has a natural honey scent and may not mix well with other fragrances.
When selecting a fragrance, it is also important to consider the safety aspects. Avoid using perfumes or crayons as they are not meant to be burned and can affect the scent throw or produce a bad smell. Always use fragrance oils specifically designed for candle-making to ensure safety and the best results.
Lastly, personal preference plays a crucial role in choosing a fragrance. Whether you prefer floral, musky, spicy, or any other scent, the options are endless. You can even create your own blend of fragrances to make unique, personalised candles.

Calculating the right amount of fragrance
When making scented candles, it is important to calculate the right amount of fragrance to use. This is called the "fragrance load" and it will determine the scent throw of the candle, including the cold throw and hot throw. The cold throw refers to the strength of the fragrance emitted by an unlit candle, while the hot throw refers to the strength of the fragrance emitted by a burning candle.
To calculate the fragrance load, you need to know the volume of your container and the weight of the wax you are using. First, determine the volume of your container by filling it with water and then pouring the water into a measuring cup. This will help you measure the exact volume without having to guess. Next, weigh the wax using a kitchen scale before melting it. This will make it easier to mix in the fragrance later.
The amount of fragrance you add will depend on the type of wax and fragrance you are using. Most waxes can hold up to 12% fragrance, with store-bought candles containing an average of 6% fragrance and premium candles containing up to 10%. As a rule of thumb, it is recommended to use between 6 to 10% fragrance in your candle mixture to optimize scent throw and maintain candle stability. For example, if you are using a soy wax that can hold up to 10% fragrance and you are making a 10-ounce candle, you would need to use 1 ounce of fragrance.
If you are using essential oils, you may need to experiment to find the right ratio as they can vary in strength and create a weaker scent than fragrance oils. A common starting point is to use a ratio of 1 ounce of fragrance per 1 pound of wax, but you may need to adjust this depending on your preference and the specific essential oil you are using. It is important to note that essential oils will smell stronger in melted wax than when the candle is burning.
Additionally, the size and type of wick you use can also affect the fragrance load. A wick that is too small may not burn across the full diameter of the candle, impacting the scent throw. It is important to refer to wick sizing charts and test your candles to ensure the wick is the appropriate size.

Preparing the container
Once you've chosen your container, it's time to prepare it for the candle-making process. Make sure the container is clean and dry. Determine the amount of wax you will need by filling the container with water and pouring it into a measuring cup. This will ensure that you have enough wax without wasting any.
The next step is to attach the wick to the container. Start with a wick that is longer than the container's height. You can use a wick sticker or dab some hot glue or melted wax onto the bottom of the wick to secure it in place. Place the wick in the centre of the container and press it down firmly. If your container has a wide diameter, you may need to use multiple wicks to ensure even burning. You can stabilise the wick by laying a popsicle stick or pencil across the top of the container and wrapping the loose end of the wick around it.
Another important consideration is the type of wax you will be using. Different types of wax have different fragrance-holding capacities. For example, beeswax already has a natural honey scent and may not hold additional fragrances as well as soy wax. Paraffin wax holds scent the best but can release chemicals and soot. Soy wax is a popular choice and can hold up to 10% fragrance.
Finally, preheating your containers can help slow down the cooling process and prevent the wax from shrinking and pulling away from the container. Monitoring the temperature with a thermometer throughout the candle-making process is essential to ensure the best results.

Adding the fragrance
Adding fragrance to your candle is a crucial step in the candle-making process. It involves careful consideration and precision to ensure the desired scent throw and candle burning behaviour. Here is a detailed guide to help you add fragrance effectively:
Choosing the Right Fragrance
The type of fragrance you choose plays a significant role in the overall scent and burning characteristics of your candle. You can opt for essential oils, which are natural but may result in a weaker scent. If you prefer a stronger fragrance, fragrance oils or synthetic fragrance oils are recommended. These are specifically designed for candle-making and offer a more potent scent. Additionally, consider the type of wax you are using. Fragrance oils may interact differently with different wax types. For example, beeswax already has a natural honey scent, so adding fragrances may yield unpredictable results.
Calculating Fragrance Quantity
To achieve the desired scent intensity, calculating the right amount of fragrance is essential. The general rule of thumb is to use between 6% to 10% fragrance in your candle mixture. This translates to approximately 1 ounce of fragrance per 1 pound of wax. However, different waxes have varying maximum fragrance capacities, so be sure to read the instructions for your chosen wax. Additionally, consider the size of your container and the amount of wax used, as these factors will influence the required quantity of fragrance.
Preparing the Fragrance
Before adding the fragrance, ensure your wax has melted and cooled to the appropriate temperature. The ideal temperature for adding fragrance is around 180°F to 185°F (85°C). Stirring the fragrance into the wax at this temperature helps prevent the oil from settling at the bottom, ensuring an even distribution of scent. Allow the wax to cool slightly before adding the fragrance; this prevents the fragrance from burning off too quickly and ensures a more consistent scent throw.
Once your wax has reached the optimal temperature, it's time to add the fragrance. Weigh out the recommended amount of fragrance oil into a small container. Then, carefully pour or stir the fragrance oil into the melted wax. Avoid adding too much fragrance, as this can affect the burning properties of the candle. If using essential oils, you may need to experiment with different oils and ratios to find your preferred scent blend.
Testing and Adjusting
After adding the fragrance, it is crucial to test your candle to ensure it burns properly and emits the desired scent. This may involve making adjustments to the type of oil, the quantity used, or the ratio of different oils in your blend. Remember, creating a strongly scented candle takes time and experimentation. Don't be afraid to make adjustments until you achieve the perfect fragrance for your candle.

Frequently asked questions
The simplest way to add fragrance to a candle is to choose a fragrance option such as an essential oil, a synthetic fragrance oil, or a commercial candle-making scent. Light your candle and let it burn until there’s a large puddle of melted wax around the base of the wick. Then add a drop of your chosen scent to the melted wax using a dropper or pipette.
Essential oils are inefficient for a good scent throw, so if you want a strong fragrance, it's best to use fragrance oils. Most waxes will not hold more than 12 per cent fragrance, but some premium waxes can hold up to 10 per cent. Paraffin wax holds scent the best, but it releases chemicals and soot into the air. Soy wax is a good natural alternative, but beeswax is already naturally scented, so mixing fragrances with it may give unpredictable results.
The amount of fragrance you need depends on the volume of your container and the type of wax you are using. A good rule of thumb is to use between 6 and 10 per cent fragrance in your candle mixture. For example, if you are using a soy wax that can hold up to 10 per cent fragrance and you are making a 10-ounce candle, you would need to use 1 ounce of fragrance.
