There are many ways to colour a candle, from using crayons to food colouring. However, not all methods are created equal. For example, while food colouring may seem like an obvious choice, it will not blend or bind with the wax. Similarly, crayons are too waxy and dense to create an effective candle that burns properly. So, what are some good ways to colour your candles? Well, you can use candle dye chips, dye blocks, or liquid dyes. These dyes are often compatible with all types of wax and can be purchased from specialist candle-making suppliers.

What You'll Learn
Choosing the right dye for your candle
Types of Dyes
The two main types of candle dyes are granular dyes and liquid dyes. Granular dyes, also known as grain dyes, include powder, chips, and blocks. They are easy to use, compatible with all types of wax, and allow for rapid setting and easy conservation for future use. Liquid dyes, on the other hand, offer practical benefits such as easy colour mixing and high colour saturation. They are particularly suitable for paraffin and gel wax and ensure colour longevity.
Colour Intensity
The amount of dye you use will determine the intensity of the colour. A good rule of thumb is to multiply the total batch size by 0.05% to estimate the amount of dye needed. For example, to colour 450 grams of wax, you would need approximately 0.227 grams of dye. Remember that some colours, like navy blue or hunter green, may require more dye to achieve the desired shade.
Compatibility
When choosing a candle dye, ensure it is specifically made for wax to guarantee even colouring and safe burning. Avoid using ordinary liquid dyes like food colouring, as the watery dye and oily wax will separate, resulting in an unsightly splotchy effect. Similarly, natural mica should be avoided as it can clog the wick during burning.
Experimentation
Before committing to a large batch, it is advisable to experiment with small amounts of dye and wax to test the colour intensity and technique. This will help you perfect your desired shade and ensure a consistent colour throughout your candles.
Additives
Consider any fragrances or essential oils you plan to use in your candles, as some additives may alter the finished colour. For example, fragrances with high amounts of vanillin or additives like sweet orange oil can change the colourant's hue over time. Always test your dyes with any additives to ensure the final colour meets your expectations.

How to add colour to your wax blend
Adding colour to your wax blend is a simple process, but it requires precision and patience. The first step is to ensure your wax is in the correct state to receive the colourant. Your wax must be fully melted to incorporate any colourant effectively. The ideal temperature range for your wax is between 160°F to 185°F. If your wax is too hot or too cold, the colour may not blend properly, leaving behind dye particles.
The next step is to determine the amount of colourant to add. This depends on the type of colourant and the desired shade. If you are using liquid dye, a single drop is enough to colour an entire pound of wax. Dye blocks can be shaved to adjust the shade, and a single block can colour 5-50 lbs. of wax. With dye chips, one chip is sufficient for one pound of wax.
When using natural mica, do not exceed 2-3 grams of mica per 100 grams of wax. It is important to note that mica may not be the best option for colouring candles, as it can clog the wick and alter combustion. Similarly, crayons, oxides, and pigments should be avoided as they can cause wick clogging issues and changes in texture and smell.
Always test your colourants to ensure you achieve your desired shade. You can do this by placing a couple of drops of wax on a white piece of paper to preview the final colour. Additionally, if you are using fragrance oils, add them before the colourant, as they can affect the chemical makeup of the colourant.

Using crayons to colour candles
To use crayons for colouring candles, start by choosing your desired crayon colours. Look for crayons with spots of other colours or dull ones that no longer colour well. You will need a good amount of crayons, around 10-15, and select colours that go well together, such as green and blue or orange and yellow. To remove the crayon wrappers, fill a bowl with cold water and ice, let the crayons sit for 5 minutes, then snap them in half and peel off the wrappers.
Chop the crayons into small pieces and mix them with pellets of regular candle wax in a heatproof cup. You can then melt the wax by placing the cup in a pot of heated water on medium heat, stirring regularly until it is completely molten. Once melted, remove from the heat and add essential oils for fragrance if desired.
When working with wax, avoid applying direct heat as it may alter its consistency. Instead, use a double boiler or a glass mixing bowl inside a pan of hot water. Gradually increase the temperature to around 180 degrees Fahrenheit while constantly stirring until all the wax is molten.
After melting the wax, it's time to add the colour. Ensure you add small amounts of crayon at a time and stir the wax for a few minutes to incorporate the colour evenly. You can then pour the coloured wax into a mould of your choice, but work quickly as the wax will start to set up fast. Let the candle set for about 5 minutes before inserting the wick.
Choosing the right wick size is crucial in candlemaking. While there is no exact formula, consider factors such as the type of wick, the size of your candle, and the additives used. Test your candle creations to find the wick size that works best. Additionally, you can use additives like stearic acid to harden the wax and lustre crystals to enhance the colours.

The best natural colourants
Natural colourants can be used to dye candle wax and create a rustic look. However, natural dyes have lower lightfastness and preservability than other pigments. Some natural colourants you could use include:
Cochineal Dye
Cochineal dye is derived from dried scale insects found on cacti. It will turn bright red when mixed with wax.
Indigo
Indigo is an annual herb of the Polygonaceae family, of which the leaves and stems are used as a dye. It is believed to originate from southern China or the Indochina Peninsula.
Indian Indigo
Indian Indigo is a natural pigment that will turn your candle a dark shade.
Tea Bags
You can use tea bags to dye your candle wax. The tea bags need to be soaked in hot paraffin wax to release their colour. The shade of the dye will depend on the type of tea used.
Mica
Mica is a naturally occurring mineral often coated in additional minerals such as iron and tin oxides. Mica has a beautiful reflective quality much like glitter, but it is finer in consistency and particle size. Mica can be used as a finishing touch to your candle if used carefully, as it can clog the wick when burning.

How to create a marble effect on candles
Creating a marble effect on candles can be done in several ways. The swirling method and the painting method are two popular techniques for achieving this unique and beautiful design. Here is a step-by-step guide on how to create a marble effect on your candles using these techniques:
Swirling Method:
First, determine the weight of the wax needed, which is typically around 14 ounces (0.53 kg) for a marble pillar candle. Place the wax in a pouring pitcher and melt it in a double boiler or on a hot plate until it reaches a liquid state. Weigh and add your chosen fragrance oil, stirring gently for two minutes to ensure proper binding. Allow the wax to cool slightly below the recommended pouring temperature to prevent dye reactivation.
Now, it's time to add the marble effect. Place a wick in your chosen jar and centre it using a wick sticker. Add a small amount of coloured wax to the bottom of the jar, then slowly roll it around the sides, creating vibrant, organic swirls. You can also use a skewer or toothpick to push the dye along the sides of the jar, creating a swirl pattern. Experiment with different amounts and colours of dye to achieve your desired look. Allow the candle to cool completely, then remove the wick bar and trim the wick to 1/4 inch (0.635 cm).
Painting Method:
For this method, you will paint coloured wax inside the jar before pouring the main wax, creating a swirling pattern. Heat the wax to 130°F (approximately 54°C) and apply the dye along the jar's edge, allowing it to cool completely. You can also try using a syringe with coloured wax once the candle is in the slush stage to create a marble effect. Trim the wick to 1/4 inch (as with the swirling method) and attach a warning label to the underside of the candle.
Additional Tips:
- Choose complementary colours that will blend nicely together, as they will combine as the candle melts.
- Marble candles can feature high-contrast, brush-like lines or a subtle, smoked-out effect. Experiment with different colours and patterns to create unique designs.
- Natural mica can be used on the surface of the candle to add a glittery effect, but it does not mix well with wax and can clog the wick.
- Liquid candle dye is practical and intensifies the colour of your candle. It is compatible with all types of wax and can be stored for future use.

Frequently asked questions
You can use candle dye chips, blocks, or liquids. You can also use some off-label colourants like micas, oxides/pigments, crayons, and food colouring, but these may not work as well as commercial dyes.
The amount of dye you should use depends on the type of dye and the type of wax. Generally, you need 3 grams of dye grain for 1 kilogram of wax. For liquid dye, 15 millilitres of dye is enough for up to 1 kilogram of wax. If you are using liquid dye, one drop of dye should be enough to colour a whole pound of wax. If you are using candle dye chips, one whole chip would be enough to colour one pound of wax.
Your wax must be fully melted in order to fully incorporate any colourant. Depending on the wax you are using, most times the wax would have fully melted at around 175°-185° F. You want to add your colourant during this state in order to receive the best results. Adding colourant to your wax while it is too hot or too cold can cause the colour to not incorporate consistently with the wax or cause the colourant to not dissolve completely.
You can choose any colour you like! If you're feeling creative, you can even mix colours for unique blends.
