Why choose soy candles?
Before getting into the details, it's important to understand the reasons why this type of candle has won the hearts of many people, especially in a city like Barcelona, where sustainability and ecological awareness are deeply rooted.
Environmental benefits of soy candles
They have a significantly lower environmental impact compared to traditional paraffin candles. Paraffin, a petroleum derivative, is nonrenewable, and its manufacture involves a larger carbon footprint. In contrast, soy wax is biodegradable, renewable, and is extracted from soybeans, a natural resource grown without damaging the environment.
Soybean cultivation also has a lower environmental impact than extracting the petroleum used to make paraffin candles, making the candles a much more sustainable and eco-friendly option.
Better for your health
Paraffin candles can release toxins and harmful compounds when burned, such as benzene and toluene, which are known carcinogens. Because they are natural, they don't emit these toxins, making them a healthier choice for your home.
Additionally, soy wax burns at a lower temperature, which can also help reduce the amount of toxins released when burning candles. Soy candles, therefore, offer a cleaner and safer burn.
Durability and cost
They last much longer than paraffin candles. This is especially important if you're making candles for sale, as customers value quality and durability. Additionally, since soy wax has a lower melting point, soy candles tend to melt more slowly and evenly, ensuring a longer-lasting experience.
Materials needed to make soy candles

You'll need some basic materials, which can be easily found at local craft stores or through online suppliers. Below is a complete list of materials you'll need to get started:
1. Soy wax
Soy wax is the main component of your candles. Make sure you purchase good quality soy wax, preferably untreated or blended with other ingredients. Flake soy wax is the most common form and melts easily. In Barcelona, you can find it in specialty natural product stores or through online platforms.
There are different types of soy wax, and some are better suited for certain types of candles. If you're just starting out, it's recommended to use soy wax for candles in general, as it's the most versatile.
2. Cotton wicks
Cotton wicks are the most common and recommended. Choose good quality wicks that don't emit smoke or create residue. Wicks are available for different candle sizes, so be sure to choose the appropriate size based on the container you're using.
For an even burn, make sure the wick is centered in the container. Sometimes metal-based wicks can be used, but cotton wicks are generally more environmentally friendly.
3. Essential oils
Essential oils are the soul of scented candles. These oils not only add fragrance but also offer the benefits of aromatherapy. For example, lavender is known for its relaxing properties, while citrus fruits like orange and lemon are refreshing and energizing.
It's recommended to use 100% pure essential oils, as synthetic products can affect the quality of the candle. You should also keep in mind that some essential oils are more potent than others, so adjust the amount according to the intensity of the fragrance you desire.
4. Candle containers
In Barcelona, one of the charms of artisanal candles is their customization. Containers can range from recycled glass jars to elegant ceramic bowls. Recycled glass jars are popular for their vintage and eco-friendly aesthetic, while ceramic jars add a rustic and elegant touch.
It's important that the container be heat-resistant to prevent it from breaking or warping while the candle is burning. Also, make sure the container is clean and dry before pouring the wax.
5. Cooking thermometer
A kitchen thermometer is essential for monitoring the temperature of the wax as you melt it. Soy wax should be between 70°C and 75°C to ensure it melts properly and the essential oils blend properly.
6. Colorants (optional)
If you want your candles to have a vibrant color, you can add natural or candle-specific dyes . Vegetable-based dyes are ideal if you're looking for an eco-friendly option. However, this step is completely optional and depends on your personal taste.
How to make soy candles in Barcelona : Step by step

Now that you have the materials, let's detail the steps to create your own candles in Barcelona.
Step 1: Prepare your workspace
Preparation is key. Make sure you work in a well-ventilated, clean, and distraction-free space. You can cover the surface with newspaper or a drop cloth to prevent accidental wax spills. Keeping the area tidy is essential for efficient and safe work.
Step 2: Melt the soy wax
Place the soy wax in a heat-resistant saucepan or double boiler. Heat gently to prevent the wax from burning. Use a cooking thermometer to ensure the wax doesn't overheat. The ideal temperature for melting soy wax is between 70°C and 75°C.
Once the wax is completely melted, remove the container from the heat.
Step 3: Prepare the wicks
While the wax is melting, prepare the wicks. Cut the wick to the desired length and glue the wick base to the center of the container using a little melted wax. Let the base adhere well to the bottom before proceeding.
It is important that the wick is well centered for an even burn.
Step 4: Mix the essential oils
When the soy wax has reached a temperature of approximately 60°C, add the essential oils. The recommended amount is between 20 and 30 drops per 1 pound of wax, depending on the desired aroma intensity. Stir well to ensure the oil is evenly mixed.
Step 5: Pour the wax into the containers
Carefully pour the melted wax into the prepared containers. Do so slowly to prevent spillage. Leave a small space (about 2-3 cm) at the top of the container to prevent the wax from spilling over as it cools.
Step 6: Let it cool and cut the wick
Let the candles cool for several hours, preferably overnight. Once the wax has completely solidified, trim the wick, leaving about 1 cm of height above the surface of the candle.
Additional tips
- Personalize your candles : You can add decorative elements such as dried flowers, herbs, or even small stones to give them a unique touch.
- Adjust the fragrance : If you want a more intense fragrance, you can add more essential oils, but keep in mind that too much oil could affect the burn quality.
