Creating scented candles is a delicate process that requires precise measurements to avoid an overpowering or underwhelming fragrance. The key to success is calculating the correct ratio of fragrance oil to wax, which typically ranges from 6% to 10% fragrance oil relative to the total weight of the candle. Candle makers use digital scales to measure the desired amount of fragrance oil in either ounces or grams, ensuring consistency in their creations. The type of wax and its maximum fragrance load are also crucial factors to consider, as they determine how much fragrance oil the wax can hold without compromising the candle's performance and scent. With careful measurements and experimentation, crafters can produce scented candles that delight consumers and reinforce brand quality.

What You'll Learn

Using a digital scale
First, prepare your workspace by placing a paper plate on the digital scale. This protects the scale from the hot wax you will be pouring later. Turn on the scale and allow it to reach zero, ensuring it is calibrated correctly. You can measure in ounces or grams, depending on your preference. Remember, never measure in liquid ounces, as this can lead to inaccurate measurements.
Next, place your pouring pot on the scale and tare it to zero. This step ensures that you only measure the weight of the fragrance oil you will be adding. Take your bottle of fragrance oil and slowly pour it into the pot until you reach the desired amount. A good starting point is one ounce of fragrance oil for every pound of wax, but you can adjust this ratio based on the wax's capacity for fragrance. Some waxes can hold more or less fragrance, so it is essential to check the wax supplier's specifications.
Once you have added the fragrance oil, use a metal spoon to stir the mixture thoroughly. Stirring helps bind the fragrance oil to the wax. Continue stirring until the fragrance oil is fully incorporated and no longer visible. Sometimes, it may take longer to stir the fragrance oil into the wax completely.
If you are working with a large batch of wax, you can calculate the fragrance oil amount using percentages. Multiply the total weight of the wax by the percentage of fragrance you want to add. For example, if you have 64 ounces of wax and want to add 6% fragrance oil, you would calculate 64 x 6% (.06), which equals 3.84. You can round this up to 4 ounces of fragrance oil.
Finally, always check the maximum fragrance load recommended for the type of wax you are using. Most waxes have a maximum fragrance load of 10%, but this can vary, so refer to the product page or the wax supplier's website for accurate information.

Weighing fragrance oil
Firstly, it is important to understand the concept of fragrance load, which is essentially the percentage of fragrance oil you want in your candle. The fragrance load can vary, but it typically ranges from 6% to 10%. Most waxes have a maximum fragrance load of 10% or approximately 1.6 ounces per pound. However, some candles may require a lower or higher fragrance load depending on the desired strength of the scent.
When you have determined the fragrance load, it's time to do the math. Let's say you are working with 200 grams of wax and want a 10% fragrance load. Simply multiply the weight of the wax by the fragrance load: 200 grams x 10% = 20 grams of fragrance oil. This calculation ensures you add the right amount of fragrance oil to your wax.
Now, it's time to get your equipment ready. You will need a scale, preferably a digital scale, to measure the fragrance oil accurately. Place a small glass beaker or a paper plate on the scale to protect it from the hot wax. If using a glass beaker, make sure it has a pour spout for easy pouring later. Tare the scale to zero so that the weight of the container is removed, and you are only measuring the weight of the fragrance oil.
Finally, slowly pour your fragrance oil into the container on the scale until you reach the desired amount. For example, if your calculation resulted in 20 grams of fragrance oil, continue pouring until the scale reads 20 grams. Once you have added the correct amount, you can proceed to mix the fragrance oil with the wax. Stir thoroughly for about two to three minutes to ensure the fragrance oil is completely bound to the wax.
Remember, always refer to the wax manufacturer's instructions or product page to determine the maximum fragrance load their wax can hold. Additionally, be cautious when working with fragrance oils, as they can react to some containers. Always use glass or paper containers and avoid plastic ones.

Ratio of oil to wax
The ratio of oil to wax is a crucial aspect of making scented candles. It is important to get this ratio right to ensure the fragrance is prominent and the candle burns properly. The fragrance load is usually given as a percentage, and this is the industry standard to ensure consistent results. Most waxes have a maximum fragrance load of 10%, or approximately 1.6 oz. per pound. A typical amount is about 6% or 1 oz. per pound.
It is important to note that the type of wax you are using will determine the maximum fragrance load it can hold. Therefore, it is recommended to check the product page for the specific wax you are using to find out its maximum fragrance percentage. This information is usually available on the wax supplier's website.
Now, let's break down the steps to calculate the ratio of oil to wax:
- First, determine the weight of the wax you will be using. This can be measured in ounces or grams, but not fluid ounces. For example, let's say you are using 1 lb. (16 oz.) of wax.
- Next, decide on the fragrance load you want to use. For this example, let's use 6%.
- Multiply the weight of the wax by the fragrance load percentage. In our example, it would be 16 x 6% (.06), which equals 0.96. You can round this up to 1 oz.
- Place a small cup or glass on a scale and tare it to zero out the weight of the cup.
- Pour the calculated amount of fragrance oil into the cup.
It is important to remain consistent in your calculations and be transparent about your methods on product labels or packaging. Additionally, make sure to stir the fragrance oil and wax thoroughly for a few minutes to ensure they are fully combined.

Stirring the mixture
Firstly, it is important to use the correct tool for stirring. A metal spoon is recommended as it can withstand the heat of the wax and fragrance oil mixture. Using a metal spoon, gently stir the mixture for at least two to three minutes. The goal is to bind the fragrance to the wax completely, so be sure to stir long enough to achieve this. If you notice the fragrance oil floating on the surface or the mixture looking uneven, continue stirring until you achieve a consistent blend.
The stirring process may take longer, depending on the type of wax and fragrance oil you are using, as well as the ratio of oil to wax. Some waxes may require more time to fully incorporate the fragrance oil. Additionally, certain fragrance oils may have different binding properties, which can affect the stirring time. Always refer to the product specifications provided by the wax and fragrance oil suppliers to understand their unique characteristics and any specific instructions.
While stirring, maintain the temperature of the mixture. It is important to keep the wax at a consistent temperature throughout the process to prevent it from solidifying or becoming too cool, which can affect the binding process. The ideal temperature for adding fragrance oil is around 185°F. However, different waxes may have specific temperature requirements, so be sure to refer to the manufacturer's instructions.
Finally, practice caution when working with fragrance oils. Some oils can react with certain containers, so avoid letting the mixture sit in paper or plastic cups for extended periods. Always follow safety guidelines and best practices when working with hot wax and fragrance oils to create a safe and enjoyable candle-making experience.

Choosing the right container
Glass containers are a popular choice for candles as they are heat-resistant and allow the candlelight to shine through, creating a warm and inviting ambiance. Ceramic containers are also an option, but they may need to be handled with care to avoid breakage. Metal tins are another alternative, though they can get very hot, so caution is advised when handling them.
The size and shape of the container are also important considerations. The container should be large enough to accommodate the desired amount of wax and fragrance oil, with extra space to allow for the wick and any additional decorations or labels. A wider container will also result in a larger wax pool, which can impact the fragrance throw of the candle.
Additionally, consider the style and design of the container to ensure it aligns with your desired aesthetic. The container can be a simple and elegant part of your candle's overall appeal or a decorative piece that enhances the ambiance you wish to create. You can choose from a variety of colours, patterns, and designs to find the perfect container that reflects your unique style and complements your candle's fragrance.
