Using essential oils

To make your own scented candles with essential oils, you will need the following:

  • Soy wax flakes
  • Wicks (hemp-based wicks are a natural option)
  • Essential oils of your choice (about 80-100 drops, depending on potency)
  • A large pot for boiling water
  • A candy thermometer
  • Weighing scales
  • A silicone spatula
  • A disposable stirring device (a wooden dowel, chopstick, or pencil)
  • Glass jars (mason jars work well)
  • Skewers

First, grab your container of choice. This could be a glass bowl or a mason jar. Lay the metal end of the wick flat along the bottom of the container and use a bit of wax to anchor it in place. Tape the top end of the wick to a skewer so that it is pulled completely straight and lay the skewer on top of the container with the wick outstretched.

Next, melt the soy wax in a pot over low to medium heat. The wax should melt fairly easily, but you can turn up the heat slightly if it is taking too long. Once melted, add your essential oils directly to the pot and stir well for about 2 minutes to allow the molecules to bond to the oil.

Now, carefully pour the wax into your jars. Leave them untouched overnight to set. The next day, trim the wicks to the desired length. If you want, you can put custom labels on your jars.

Your essential oil candles are now ready to be enjoyed!

Adding fragrance oils

Next, you will need to prepare your container and wick. Place the wick in the centre of your chosen container, ensuring it is pulled taut and straight. You can tape the top of the wick to a skewer laid across the top of the container to keep it in place.

Now, you are ready to add your fragrance. Melt an inch or two of wax around the wick by lighting the candle and then blowing it out. Add 3-4 drops of your chosen fragrance oil and stir the wax with a toothpick or skewer. You can add more drops if you want a stronger scent. Allow the wax to cool and harden, which will enable the scent to be deeply absorbed.

Once the wax has cooled, you can light your candle and enjoy your chosen fragrance. If you are unhappy with the scent's strength, you can repeat the process, adding more drops of oil. For a natural, decorative touch, you can add dried petals or herbs, such as lavender or rosemary, to the wax before it hardens.

There are also scented wax cubes available, which can be placed into melted wax to emit a strong fragrance. These can be purchased from most large retailers and offer a wide range of scent options.

Scented wax cubes

To use scented wax cubes, place a few cubes in a wax warmer. The warmer can be electric, heated by a small lightbulb, or use a ceramic heater. Turn on the warmer or plug it into an electrical outlet, and the heat will melt the wax cubes, releasing their scent.

Once you are done using the wax cubes, turn off the warmer and unplug it if necessary. Allow the wax to cool and solidify before removing it from the warmer. You may need to scrape the wax out or pop it out of a silicone dish. Wipe down the warmer with a paper towel to clean it.

Natural scent extraction methods

  • Distillation: This process involves heating raw plant material to extract volatile oils. There are two types of distillation: steam distillation and dry (or destructive) distillation. In steam distillation, steam is used to help extract the oils, while in dry distillation, the plant material is heated without water, resulting in a slightly toasted scent.
  • Solvent Extraction: This method uses chemical solvents such as hexane or diethyl ether to remove aromatic lipids and waxes from plant matter. It is often used for plants that are sensitive to heat and cannot be distilled, such as jasmine or tuberose.
  • Expression: This technique involves physically squeezing or pressing the plant material to extract the aromatic compounds.
  • Enfleurage: This process is labour-intensive and expensive. It involves spreading a layer of fat, such as animal fat or solid plant oil (like coconut oil), on a glass plate. Delicate petals or flowers are placed on the fat without touching each other, and then another glass plate is placed on top. This process is repeated to create a "glass-fat-flower sandwich." After setting for several days, the flowers are replaced with fresh ones, and this process is repeated for about a month. The fat absorbs the concentrated scent of the flowers and is then scraped off the glass plates as a waxy pomade.

Once the scents are extracted using these methods, they can be added to candles. One way to do this is by melting an inch of wax around the wick of a candle and adding 3-4 drops of fragrance oil. The wax is then stirred, allowed to cool and harden, and the candle is lit to release the scent. Alternatively, dried flowers, crushed herbs, cinnamon sticks, or cloves can be added directly to the candle wax for natural scents and decoration.

Mixing and matching scents

Mixing candle fragrances is an art that takes practice. By understanding how to mix and match different candle scents, you can create unique and captivating fragrance experiences. Fragrance notes are the building blocks of any scent and are typically categorized into three layers: top, middle, and base notes. Here are some tips to help you create your own scent combinations:

  • Understand fragrance notes: Top notes are the initial scents perceived when the candle is lit, such as citrus, mint, and light florals. Middle notes, also known as heart notes, emerge after the top notes fade and include scents like lavender, jasmine, and spices. Base notes are the scents that linger after the candle has burned, such as vanilla, musk, wood, and amber.
  • Use a fragrance wheel: Start by understanding the relationships between different scent families using a fragrance wheel. This will help you identify scents that complement each other.
  • Experiment with ratios: When mixing fragrances, start with equal parts of each scent and adjust the ratios as needed. For example, if you're making an apple-vanilla candle, you could use one part apple fragrance and one part vanilla fragrance.
  • Stir thoroughly: After adding the fragrances, stir the mixture for 90-120 seconds to ensure proper binding of the wax and fragrance.
  • Tailor scents to different rooms: Consider the purpose of the candle and the atmosphere you want to create. For example, a living room might benefit from a balanced and welcoming scent pairing, such as combining vanilla with citrus.
  • Layer multiple scents: When using multiple candles, start by lighting the base scent, which should be the stronger or more grounding fragrance. After a few minutes, light the second candle, which will add complexity and depth. For a three-candle setup, add a top note after the first two have blended.
  • Practice and experiment: Creating unique candle scents takes practice and experimentation. Start with small batches and test different fragrance combinations until you find the perfect blend.
