Candle Dyes: Oil-Based Or Not?

There are various ways to colour candles, including using crayons, candle dye flakes, food colouring, and liquid candle dye. While food colouring can be oil-based, and therefore easier to mix into candle wax, it is not designed to be used near an open flame. Candle dyes, on the other hand, are formulated to bond with candle wax. They are available in different forms, such as dye blocks, chips, flakes, and liquids, with liquid dyes being the most concentrated and easiest to use. These dyes are typically oil-based or paraffin-based and are added to hot wax to create vivid colours.

Candle dyes are often oil-based

Dye blocks, on the other hand, are typically paraffin-based. They are not recommended for use in gel candles as they may not mix well with the wax. Candle dye blocks can be used to create pastel to medium shades and deep colours. Soy dye flakes, for instance, can be added when the wax is at its hottest, around 185° F, to ensure they fully melt. The dye flakes vary in size, so it is recommended to break them up with your fingers before measuring to ensure consistent colouring.

Candle-making enthusiasts can also get creative with layering different colours to achieve fun effects. It is important to allow each layer to cool completely and pour the next layer at a temperature no higher than 140° F to prevent bleeding. Additionally, dyes are UV light-sensitive and should be cured and stored in a shaded area, away from direct sunlight. Using a UV inhibitor helps maintain vivid colours over time and reduces the likelihood of fading or discolouration.

There are various types of candle dyes available in the market, and it is important to choose one suitable for the specific type of candle being made. For example, crayons are not recommended as they can clog the wick and prevent the candle from burning properly. Food colouring can be used, but it is not ideal as it contains ingredients like water, propylene glycol, and glycerin, which do not bond well with the wax. Essential oils like sweet orange oil can also be used to alter the finished hue, but they may change the colour over time.

Food colouring can be used as a substitute

While candle-making dyes are typically oil-based, food colouring can be used as a substitute. Candle-making dyes are available in a variety of forms, including liquid, powdered, and block. Block and powdered dyes are best for candle-making, while liquids are ideal for combining colours and creating high colour saturation.

Food colouring is a popular choice for colouring candles due to its ultra-concentration, economical price, and wide range of colours. However, it's important to note that liquid and gel food colourants contain ingredients like water, propylene glycol, glycerin, citric acid, alcohol, high fructose corn syrup, and agar gum, which can be complex to work with. These ingredients can make it challenging for the colourant to bond with the wax, and introducing water to a candle can potentially cause it to pop or explode.

To use food colouring effectively for candle-making, it's recommended to add the colourant when the wax is at its hottest, ensuring it fully melts. The recommended temperature for adding the dye is around 185° F. Additionally, it's important to add small amounts of colourant at a time, stirring the wax for a few minutes to achieve an even colour.

It's worth mentioning that colours may vary with different wax, fragrance, and additive combinations. Therefore, experimenting and taking notes is essential to achieving the desired colour and ensuring the safety of the final product.

While food colouring can be used as a substitute for candle-making dyes, it's important to carefully follow instructions and be mindful of the potential challenges to ensure a safe and successful candle-making experience.

Candle dye flakes are another option

There are several different kinds of dyes created specifically for dying candles. Candle dye flakes are another option. Soy dye flakes are generally recommended for pastel to medium colours, but it is possible to achieve deep shades with these flakes. The dye flakes vary in size, so the best way to ensure consistent measurements is to break them up with your fingers before measuring. You can also mix your dye flake colours to make additional colours. Keep a log to record your measurements so you can recreate them. When layering your colours, always allow the wax to cool completely before pouring the next layer. It is recommended to pour at a cooler temperature, no higher than 140° F, to ensure the colours do not bleed.

Candle dye flakes are very easy to use. You just add them to your wax when it is at its hottest, around 185° F, to ensure they fully melt. You can also add them at the start to your wax or at the end just before you pour.

Candle dye flakes are different from liquid candle dye, which is another popular option. Liquid candle dyes are extremely concentrated, and are the quickest way to colour paraffin, soy, gel, and natural wax blends. They require only gentle stirring to achieve an even colour, and they mix easily, leaving no particles or sediment. However, liquid dyes can be very hard to clean up and they have a strong smell.

Crayons are not recommended for candle-making

Candle dyes are oil-based and are the quickest way to colour paraffin, soy, gel, and natural wax blends. They are highly concentrated and require only gentle stirring to achieve an even colour. However, if you are looking for a cost-effective alternative, you may consider using crayons. But before you do, here are some reasons why crayons are not recommended for candle-making:

Crayons Don't Burn Well

Crayons are made of paraffin wax, which is a type of wax that does not burn well. When melted, the wax will "shrink", resulting in a candle that may not burn properly or may burn out quickly. To create a usable candle, you will need to add extra candle wax to your crayon wax. The ratio is approximately six crayons per cup of wax.

Colour Limitations

Crayons are available in a limited range of colours, and it can be challenging to find shades that complement each other. Moreover, the colours may not be as vibrant as those of candle dyes, resulting in dull-looking candles.

Difficulty in Achieving Consistent Colours

When using crayons, it is challenging to achieve consistent colours across multiple batches of candles. This is because crayons vary in size, and it is difficult to ensure precise measurements when breaking them up.

Time-Consuming Process

Creating candles with crayons can be a time-consuming process. It involves peeling off the crayon wrappers, cutting or shredding the crayons into small pieces, melting them, and then stirring the mixture regularly. Additionally, if you want to create striped or layered candles, you will need to melt each colour separately and wait for each layer to set before adding the next one.

Potential Safety Hazards

Working with hot wax and stoves or ovens can pose potential safety hazards. It is crucial to have adult supervision and take the necessary precautions, such as using oven mitts and avoiding touching hot surfaces.

While using crayons for candle-making can be a fun and creative project, it is important to be aware of these limitations and potential challenges. Candle-making dyes are designed specifically for this purpose and can provide more consistent, vibrant, and safe results.

Dyes are UV light sensitive

Candle dyes are indeed oil-based. They are highly concentrated and can be used to colour paraffin, soy, gel, and natural wax blends.

UV light is a form of electromagnetic radiation that radiates at shorter wavelengths than visible light and cannot be seen by the human eye. However, when certain materials absorb UV light, it is reflected back towards the eye as longer-wavelength visible radiation, or visible light. This phenomenon is known as UV-induced visible fluorescence.

Observation of UV-induced visible fluorescence can be used as a non-destructive analytical technique to aid in the examination of objects. For example, it can assist with materials identification, detecting insect damage or surface coatings, and uncovering areas of previous restoration.

However, it is important to exercise caution when drawing conclusions based solely on UV-induced visible fluorescence examination, as it may produce misleading results or be easily misinterpreted. Additionally, long-term exposure to UV radiation can lead to serious and irreversible vision problems and may increase the risk of skin cancer, so it is important to minimise exposure to unprotected skin.
