Welcome, soy friend!

Is there anything better than lighting an essential oil candle as the sun sets on the day, replacing the warmth of the sun for the glow and atmosphere of a candle flame with scents from far-flung places.

If you haven’t started making soy candles yet, what are you waiting for? Not only will you save a fortune on shop-bought candles, but you’ll know exactly what goes in your candle and why you put it in there.

At Wickpy, we keep candle making natural, good for our health and wellbeing, and good for the planet. Making candles with soy wax and essential oil oils helps us to achieve this.

Soy wax is made from the soybean plant, making it a more eco-friendly option than petroleum-based paraffin wax. Soy wax burns very clean, leaving none of the soot marks that paraffin candles leave behind.

Essential oils make wonderful additions to soy candles. They are natural, offer therapeutic value and don’t irritate allergies like synthetic sources of fragrance can. So, we love to scent soy candles with pure essential oils, usually as blends which target an intention e.g. to have a relaxing evening, a productive workday, or whatever you wish to put your mind to.

What you need to make soy essential oil candles

The great news is that you only need a few ingredients to make soy candles with essential oils.

  • Soy Wax - the amount of soy wax you need will depend on the volume of the candle container you plan to make your candle in. Calculate how much soy wax you need for candles.
  • Essential Oils - the amount of essential oils you need also depends on the volume/size of the candle container and the amount of wax you use to make your candles. It also depends on how much scent you want your candle to have. Calculate how much essential oil you need for candles.
  • Wicks - most wicks available today are cotton, which is good news considering that they used to have lead in them to keep them upright, which would get released into the atmosphere as the candle burned. It’s important not to buy any old wicks like big multipacks on shopping websites. This is a rookie error where the wick chosen is not powerful enough for the diameter of the container and, when burnt, forms a tunnel down the candle eventually depriving it of oxygen to burn. Large packs of low priced wicks will come with little or no guidance as to what diameter jar they should be matched to. We recommend choosing a good quality cotton wick such as a TCR wick which offers a full range of wicks to suit most candle jar diameters. Buy TCR pure cotton wicks with metal sustainers from Wickpy on Etsy.
  • Sticky double-sided adhesives or a glue gun - either of these two is used to attach the wick to the candle container, stabilising it in the middle of the jar to an even burn all across the full diameter of the jar.
  • Clothes peg to keep the wick in place at the top of the jar once the candle is poured
  • Ban Marie - if you’re not familiar with a Ban Marie, it’s the method used to gently melt chocolate and in this case, wax. You’ll need a saucepan, water and a hob to make a Ban Marie.
  • Something to stir - a small whisk or a fork to gently blend the soy wax and essential oils
  • Candle jars - also known as candle containers, these can be upcycled food jars, empty candle jars or any jar so long as it is strong glass and isn’t super narrow or super wide in diameter. If it’s super narrow it will burn too quickly, if it’s super wide you’ll probably need 2-3 wicks to avoid a tunnel forming down the candle. Note: wicks have a pre-determined diameter they burn to, so they should be paired to your candle jar. For soy candles with essential oils, it is best to choose a jar with a lid for the curing stage of making soy candles
  • Thermometer - use them to measure the temperature of soy wax as it melts in Ban Marie, to know when it’s time to pour in essential oils, and when it's time to pour the candle. We recommend a good quality digital thermometer with fast, accurate readings. Expect to spend upwards of £12 to get a good thermometer.
  • A tray to craft on - expect a drop or two of wax or essential oil to hit your surface, so we recommend making candles on a tray or paper to protect furniture from potential spillages.

Choosing essential oils to fragrance your soy candles

Essential oils are extracted from plants, trees, herbs, fruits and flowers, making a fantastic option to fragrance soy candles naturally.

When choosing essential oils for your candles, herby, minty and floral oils tend to work well with soy wax.

You can choose, for example, to make a relaxing lavender candle or an uplifting peppermint candle. A little blending of essential oils can also be fun and experimental. By adding essential oils to a blend little by little you can adjust the scent to your preference.

How to make soy candles with essential oils

Now that you are armed with wax, wicks and essential oils you are ready to make candles.

Preparing your space for soy candle making

  • Get your candle container, wick, adhesive and stirrer together and place them on a tray
  • Fill a saucepan with a few inches of water and bring to a boil. Reduce heat to simmer
  • Place soy wax flakes into a stainless steel jug and place the jug inside the simmering water (this creates a Bain Marie)
  • Allow the soy wax to melt and use a thermometer to keep an eye on the temperature
  • While the wax heats, attach the wick to the centre of the jar using a double-sided adhesive or glue gun. if you find it’s difficult to stabilise the wick as you hold it, try using a hollow biro or straw to feed the wick through and hold both together near the top.
  • Once the wick is attached, check the temperature of the wax
  • Once the wax temperature reaches 85 degrees Celsius, remove from the heat and pour in the essential oils
  • Stir the soy wax and essential oil combination gently for two minutes to blend thoroughly. Rotate direction every few turns.
  • Leave the soy wax to cool checking on the temperature every few minutes. When the wax reached 50 degrees celsius it is time to pour the candle
  • When pouring wax for container candles, direct the wax onto the wick. Container candle wax will naturally adhere to the jar, it's the wick that the wax needs to bind with more
  • (optional) You may wish to save a little of the candle wax to top up later once the candle has set - this will help iron out any uneven surface and give a smooth finish to your soy candle
  • When you’re finished pouring the candle, open the clothes peg and slide it down the wick to rest at the top of the candle jar. Aim for the wick to be as close to the centre of the jar as possible
  • Leave the candle to set for several hours

Tidying up and curing soy candles

  • Once the candle is set, heat the wax set aside in the previous (optional) step and top up the soy candle with the wax and allow it to set
  • Trim the wick to one half of a centimetre and screw on the lid
  • At this point, you may wish to clean up any finger marks from the jar with a cloth and decorate your candle jar as you desire, or keep it clean and simple
  • We don’t recommend adding anything to your candles such as crystals or herbs. Candles are already quite a volatile item to have inside the home and should be handled with care. The additional materials that will move such as crystals or combustible items such as herbs add to the volatility of the candle and both are not recommended
  • Curing a soy candle with essential oils involves allowing the candle to rest with the lid on for 7 days upwards before lighting. Curing is recommended to be done in a space with no direct sunlight and in a reasonably cool room
  • After the curing process is ended, light your soy essential oil candle and enjoy.

Soy candle safety and care

  1. Never leave candles unsupervised
  2. Keep away from flammables
  3. Burn in an area free of draughts
  4. Trim the wick to half a centimetre before lighting for the first time and every time before you light it
  5. When burning a soy candle for the first time, allow the pool of melted wax to reach the edges of the jar before extinguishing. This may take up to a couple of hours but not allowing this to happen will create a tunnel down the candle shortening its life of the candle.
  6. Burn soy essential oil candles for a maximum of 4 hours at a time
  7. To extinguish your soy candle, push the wick into the melted wax using something metal to avoid any smoke keeping the air clean.

Recycling and upcycling soy candles

Please keep our beautiful planet tidy by recycling and upcycling candle jars Wicks can be removed with a dinner knife. Be careful, of course especially if it has been glued. If the wick was glued, pop the candle container in hot water to soften the glue and remove the wick more easily

Soy wax can be removed from candle jars using hot water. Once the water is above 50 degrees celsius the wax will begin to melt away. If there is a lot of wax remaining, pop the candle jar into hot water to melt the wax and reuse it! Residual wax can be removed with a dedicated sponge of hot water and some washing up liquid.
