What You'll Learn
Calculating the amount of wax per candle
Calculating the amount of wax needed per candle is a crucial step in candle-making. Too much fragrance can result in candles with dry or lumpy wax or even those that do not hold a flame. The fragrance load is usually between 5-6% but depends on the type of candle wax. The fragrance load is the percentage of fragrance that your chosen wax can hold.
To calculate the amount of wax per candle, you must first know the volume of your candle container. This can be done by filling the container with water to the desired level and then pouring the water into a measuring jar to get the volume.
Next, you must convert the volume of water to the volume of wax. This can be done by multiplying the volume of water by 0.86, the average gravity of candlewax. This will give you the volume of wax needed for your candle.
Now that you know the volume of wax needed, you can calculate the weight of the wax. The weight will depend on the type of wax you are using. If using wax flakes, fill your wax melting/pouring bucket with the flakes and weigh them. If using wax slabs, you will need to calculate the weight based on the volume of wax you calculated earlier.
Once you know the weight of the wax, you can calculate the weight of the fragrance oil needed. This is based on the desired fragrance load. Multiply the weight of the wax by the desired fragrance load percentage to get the weight of the fragrance oil.
For example, if you have a container that holds 9oz of wax and you want a 10% fragrance load, you would first convert the 9oz of water to wax by multiplying by 0.86, giving you 7.74oz of wax. Then, you would multiply the weight of wax by the fragrance load percentage to get the weight of fragrance oil needed. In this case, you would multiply 7.74oz by 0.10, giving you 0.774oz of fragrance oil.

How to measure fragrance oil
Making your own soy candles is a fun and simple DIY project that can make wonderful gifts. When making a single candle, it is important to know how much wax your candle vessel holds and how much fragrance to use. When making a large batch, you will base all your measurements on the total amount of wax you have by weight and add fragrance oil by weight.
Firstly, you need to work out how much liquid your jar holds by measuring up to the point it will be filled with wax. Place your preferred jar on a scale and measure it in grams. Tare it to zero. Then, pour water into your desired candle jar up until the point where you would want to fill it with wax when pouring. Record the amount and then thoroughly dry the container. Now that you have your measurements ready, you can determine how much fragrance to put into your wax. Fragrance load is the percentage of fragrance you’ll mix into your jar along with your candle wax. It is always expressed as a percentage.
When using All Seasons Wax, it is recommended to use a fragrance load of 6% to 8% to ensure a good scent throw without impacting the flame’s ability to burn through the viscous fragrance oil or causing disturbances to the top of the candle. To calculate how much fragrance to put in, multiply your jar volume by the percentage you would like to use. For example, if your jar holds 100 grams of water and you want a 6% fragrance load, you would multiply 100 grams by 0.06, which would give you 6 grams of fragrance oil.
It is important to only add your fragrance when your wax temperature is below the flash point of the fragrance, which is generally between 50-55 degrees Celsius. The flash point is the temperature at which the fragrance becomes volatile and may catch alight. Mix the fragrance in thoroughly to ensure that your candle has an even fragrance load.

Using a fragrance calculator
To use a fragrance calculator, you will need to enter the size of the finished candle in ounces (OZ). You will also need to enter the desired fragrance load as a percentage. For example, if you want a 6% fragrance load, you should enter '6' and not '6%'.
The calculator will then tell you the amount of wax you need to use in ounces. Some calculators will also tell you how many jugs you will need if you are making a batch of candles.
It is important to calculate your candle fragrance load correctly. Using too much fragrance can result in candles with dry or lumpy wax, or candles that do not hold a flame.

Adding colour with dye
Soy candles are a fun and simple DIY project that can make wonderful gifts. Adding colour with dye is a great way to make your candles more vibrant and eye-catching. Here is a step-by-step guide to achieving the perfect colour for your soy candles:
Choosing the Right Dye
Select a candle-approved dye that is specifically designed for use in wax. There are various types of dyes available, including liquid dyes, dye blocks, and dye flakes. Choose a colour that complements your fragrance and the intended purpose of the candle.
Preparing the Dye
Follow the instructions on the dye package for proper preparation. Typically, you will need to melt the dye before adding it to your wax. Use a heat-safe container placed in a pot of simmering water to create a double boiler. This will ensure that the dye is evenly distributed and ready to be combined with the wax.
Calculating the Amount of Dye
The amount of dye you need will depend on the desired intensity of colour and the weight of your wax. A good rule of thumb is to start with a small amount of dye and gradually add more until you achieve the desired shade. As a reference, a 0.2% dye concentration is common for soy candles. Calculate the weight of the dye required based on the total weight of your wax.
Adding the Dye to the Wax
Once your wax is melted, slowly add the prepared dye, stirring continuously. Ensure that the dye is fully incorporated and that the colour is consistent throughout the wax. A thorough mix will prevent any colour streaking or uneven distribution in your final candle.
Pouring and Setting
After combining the dye and wax, carefully pour the mixture into your chosen mould or container. Allow the candle to cool and set completely. This usually takes several hours, depending on the size of your candle and the ambient temperature.
Final Touches
Once your candle has set, you can add any additional decorations or labels. Trimming the wick to the appropriate length is also important for a clean burn. Your colourful soy candle is now ready to be displayed or gifted!
Remember to follow safety precautions when working with hot wax and dyes. Always work in a well-ventilated area and wear protective gear, such as heat-resistant gloves and an apron. Enjoy the creative process of crafting your unique soy candles!

Using essential oils
Soy candles made with essential oils are a fantastic alternative to common synthetic candles. They are all-natural, allowing you to scent your home naturally while also reaping the therapeutic benefits of essential oils.
When determining how much essential oil to add to your soy candle, it's important to consider the size of your container and the amount of wax you're using. The general guideline for adding essential oils to candle wax is a 1% to 3% fragrance load. This means adding about 5 to 15 ml of essential oil per pound (approximately 450 grams) of wax. For soy candles, this can be increased to a fragrance load of 6% to 10%, translating to approximately 30 to 48 ml of essential oil per pound of soy wax. However, it's important to refer to the manufacturer's guidelines for the specific soy wax you're using.
To calculate the amount of essential oil needed, you can use the following formula:
Fragrance load (%) x weight of wax (in grams) / 100 = weight of essential oil needed (in grams)
For example, if you're using 450 grams of soy wax and want a fragrance load of 8%, the calculation would be as follows:
8 x 450 / 100 = 36
So, you would need to add 36 ml of essential oil to your soy wax.
It's recommended to start with low percentages of essential oil, as some oils can behave differently at higher loads. Always measure by weight and not by drops, as essential oils vary in density, and measuring by weight ensures accuracy.
When choosing essential oils, opt for high-quality oils and consider the therapeutic benefits you're seeking. Popular essential oils for soy candles include orange, cinnamon, lavender, peppermint, bergamot, clary sage, clove, nutmeg, ginger, lemon, and vetiver. These oils offer delightful fragrances and aromatherapy benefits.
Creating your own soy candles with essential oils is a therapeutic and rewarding experience, allowing you to customise your candles to your preferred scents and intended moods.
