Candles are a source of light produced by the combustion of a wick immersed in wax. The colour of a candle flame depends on the presence of certain chemicals, and the temperature of the flame. The colour of a candle flame can be changed by using different types of wax, wicks, or by adding chemicals to the wax. Additionally, a candle flame can be transferred from one candle to another without touching the wick, by using the smoke trail produced by the extinguished candle.

What You'll Learn
Use powdered chemicals to colour the flame
To change the colour of a candle flame, you can use powdered chemicals. The first step is to choose the colour you want your flame to be. Different chemicals produce different colours, and these chemicals should always be in powdered form.
For a red flame, use strontium chloride or boric acid. For an orange flame, use calcium chloride or sodium chloride. For a yellow flame, use table salt or sodium carbonate. For a yellow-green flame, use borax. For a green flame, use copper sulfate or alum. For a blue flame, use copper chloride or calcium chloride. For a turquoise flame, use copper sulfate. For a pink flame, use lithium chloride. For a purple flame, use potassium chloride or potassium sulfate (saltpeter). For a white flame, use magnesium sulfate or Epsom salt.
Once you have chosen the colour and purchased the appropriate chemical, you can then melt your wax in a heater. Add one to two tablespoons of the chemical powder to the melted wax and stir well. Be sure to follow the instructions that come with the chemicals, as flammable chemicals can have unexpected reactions if mixed improperly.
After the chemical is fully incorporated into the wax, let the mixture cool for about 5-10 minutes. Then, pour the wax into paper cups or moulds. Once the wax has set, you can light the candle, and it will produce a coloured flame.

Melt wax, add colouring, and mould
To create coloured candles, you must first decide on the colour you wish to produce. This is because the chemical or dye you use will determine the colour of the flame. For example, to create a deep red flame, you can use lithium chloride, whereas calcium chloride will produce an orange flame.
Once you have selected your chemical or dye, it is time to melt your wax. Soy wax is a popular choice as it is natural, biodegradable, and eco-friendly. Beeswax and palm wax are also natural alternatives. However, paraffin wax, commonly used in commercial wax melts, should be avoided as it can release harmful toxins.
After melting your wax, you can add your colouring agent. If using a chemical, only a small amount is needed, approximately two teaspoons for every batch of wax. However, it is important to follow the instructions provided with the chemicals to ensure safety and the desired effect. These chemicals can be dangerous if mixed improperly, and some may cause sparking when the candle is lit.
If using natural dyes, you can create beautiful colours from herbs, spices, flowers, and fruits. Glitter can also be used, but it is important to note that it should not be added directly to the molten wax as it will sink to the bottom. Instead, sprinkle it into your moulds before pouring in the wax.
Finally, pour the coloured wax into your moulds and allow it to cool. Silicone moulds are a good option as they make it easier to remove the solidified wax. Ensure your mould is heat-resistant, simple in shape, and does not have any thin parts that could break off when removing the wax.

Soak wicks in chemical solutions
Soaking wicks in chemical solutions is a popular method to change the colour of a candle flame. It is important to note that the chemicals used can be toxic and emit fumes when burned, so it is crucial to be mindful of the health risks involved. Here is a step-by-step guide:
Choose the Right Chemicals
The first step is to select the chemicals that will produce the desired flame colour. Different chemicals produce different colours. For example, strontium chloride produces a brilliant red flame, copper chloride (CuCl₂) gives a blue flame, and potassium chloride (KCl) yields a purple flame. Other chemicals and their corresponding colours include boric acid for deep red, calcium for red-orange, calcium chloride for yellow-orange, table salt for bright yellow, and borax for yellow-green.
Prepare the Solution
Dissolve the chosen chemical in water to create a concentrated solution. The ratio of chemical to water is crucial and should be carefully measured. For example, a ratio of one part chemical to one part water by volume is recommended for creating water solutions of potassium nitrate, potassium chlorate, perchloric acid, and ammonium perchlorate.
Soak the Wicks
Once the solution is ready, soak the wicks in it. Ensure that the wicks are completely saturated and left to soak for a sufficient period. One suggestion is to leave them overnight to ensure maximum absorption.
Dry the Wicks
After soaking, the wicks must be thoroughly dried before use. Hang them right-side up and allow them to dry for at least 2 to 3 hours. A clothes rack or line with clothes pins can be useful for this step. It is imperative that the wicks are completely dry before using them in a candle, as partial dryness can cause improper curing, resulting in air bubbles, gaps, and improper burning.
Assemble the Candle
Once the wicks are dry, you can assemble your candle as you typically would. Attach the wick to the bottom of your container and then pour in the wax at the proper temperature according to the manufacturer's directions.
Safety Precautions
When burning candles with chemical-soaked wicks, always exercise caution. Do not leave the candle unattended, and avoid placing your face directly above the flame to prevent inhaling toxic fumes. Always follow safety guidelines when working with chemicals and flames.

Use a straw to blow out a candle and relight with another's flame
To change a candle flame from one to another, you can use a straw to blow out a candle and then relight it with another candle's flame. Here's a step-by-step guide:
Step 1: Set Up the Experiment
Place two candles next to each other on a flat surface. Ensure that the candles are secure and will not fall over. You can use wet sand or another non-flammable substance, such as cake or a cupcake, to hold the candles in place.
Step 2: Light the Candles
Use a match or a lighter to light both candles. Allow the candles to burn steadily for a few seconds.
Step 3: Blow Out One Candle with the Straw
Take the straw and hold it close to the flame of one of the candles. Blow through the straw to extinguish the flame. Be careful not to blow too hard, as you want to extinguish only one candle at a time.
Step 4: Relight the Extinguished Candle with Another's Flame
Immediately after blowing out one of the candles, hold the flame of the burning candle into the white smoke of the blown-out candle, close to the wick but without touching it. The blown-out candle should reignite due to the presence of vaporized wax in the smoke.
Step 5: Observe and Repeat
Observe the flame jumping from one candle to another. Repeat the experiment several times to observe the same results consistently. You can also try this experiment with different types of candles, such as those made of paraffin or beeswax, to see if there are any differences.
Remember to always exercise caution when handling candles and flames, and ensure you have an adult helper if needed.

Use a chemical scent to change the flame's colour
Using chemicals is a popular way to change the colour of a candle flame. However, it is important to note that some chemicals used in the past for this purpose have been banned for being too toxic, so it is essential to check the safety of the chemicals you are using.
One method is to mix powdered chemicals directly into the wax. To do this, melt the wax in a heater and add about two teaspoons of the colouring chemical. However, it is important to follow the instructions that come with the chemicals, as flammable chemicals can have unexpected reactions if mixed improperly. Another user reported that this method did not work for them, as the natural colour of the burning wax masked the colour of the chemical flame.
Another approach is to coat the wicks in a substance such as petroleum jelly and then sprinkle the chemical on top. This method can also be achieved by soaking the wicks in a water and chemical solution overnight. However, one user reported that this method only produced sporadic sparks of colour rather than a consistent flame.
Different chemicals produce different coloured flames. For example, strontium chloride produces a brilliant red flame, while copper chloride mixed with petroleum jelly burns with a nice blue flame. Other chemical and colour combinations include calcium for a red-orange flame, calcium chloride for a yellow-orange flame, table salt for a bright yellow flame, and borax for a yellow-green flame.
