What You'll Learn
The ideal first burn time
A good rule of thumb is to burn your candle for at least one hour per inch of the container's diameter. For example, a candle with a container diameter of 2 inches should burn for 2 hours. This is to ensure that the wax melts edge-to-edge, creating a full melt pool. This is important because it ensures the longevity of your candle and prevents tunnelling, which is when a "memory ring" is created, causing the wax to tunnel downwards instead of melting evenly.
However, you should not burn your candle for longer than 4 hours at a time. This is because, after 4 hours, carbon will begin to collect on the wick, causing it to "mushroom". This can lead to an unstable flame, an enlarged flame, and the release of soot into the air and onto your candle container.
The type of wax, wick size and number, and the presence of fragrance oils and wax additives will also impact the ideal first burn time. For example, soy wax candles burn slower than paraffin candles and will therefore need a longer first burn time. Larger wicks and candles with multiple wicks will also burn through wax faster.

How to avoid wax tunnelling
The ideal burn time for a candle varies, but it is recommended that candles are not lit for more than 4 hours at a time. A good rule of thumb is to burn a candle for at least one hour per inch of the container's diameter. For example, a candle in a container with a 3-inch diameter should be burned for at least 3 hours during its first use. This allows the candle to reach a full melt pool, where the top surface of the wax has melted from edge to edge of the container.
However, burning a candle for too long can lead to wax tunnelling, where a hole forms down the centre of the candle, leaving unused wax at the edges. This occurs when the wick is too small for the size of the candle, or when the candle is not burned long enough during its first use. To avoid wax tunnelling, ensure that the wick is the correct size for the candle and that the entire surface of the candle has melted before blowing it out.
If tunnelling does occur, there are several methods to fix it:
- Wrapping aluminium foil around the top of the candle to keep the heat in and melt the sides.
- Using a hair dryer to melt the top of the candle.
- Placing the candle in an oven at a low temperature (around 200°F or 93°C for 20 minutes) to melt the entire surface.
- Removing the wick and replacing it with a new one.
- Trimming the wick to a shorter height before lighting the candle again.

The importance of wick maintenance
Burning a candle is a great way to create a cosy atmosphere and fill your space with a beautiful fragrance. However, candle maintenance is important to ensure safety and the longevity of your candle. One of the most important aspects of candle maintenance is wick maintenance.
Firstly, before lighting your candle, always trim the wick to 1/4 of an inch. This is because wicks that are left too long can cause uneven burning, dripping, flaring, and sooting. Trimming the wick helps to control the amount of fuel that the candle is receiving, reducing the risk of flare-ups and potential fires. It also helps to prevent the build-up of carbon on the wick, which can cause the wick to become unstable and the flame to become too large, leading to smoking and soot release. By trimming the wick, you can also prolong the life of your candle by up to 25%.
Secondly, it is important to not burn your candle for too long. A good rule of thumb is to limit the burn time to 2 hours, but no more than 4 hours at a time. This is because burning the candle for longer periods can lead to the same issues caused by an untended wick, such as carbon build-up on the wick, an unstable flame, and increased smoking and soot release.
Thirdly, the type of wick you use is important. Different types of wicks, such as flat braid wicks, square braid wicks, cored wicks, and wooden wicks, burn differently. For example, wooden wicks tend to burn hotter and faster than cotton wicks. Therefore, it is important to choose the right type of wick for your candle to ensure optimal burning.
Finally, always ensure that you read the burn instructions included with your candle. These instructions will provide specific recommendations for safely getting the most out of your candle, including how to properly maintain the wick. By following these instructions, you can ensure that you are enjoying your candle in the safest and most optimal way.

Safety precautions when burning candles
Burning candles can be dangerous, so it's important to take certain precautions to ensure your safety. Here are some essential safety tips to keep in mind when burning candles:
Never leave a candle unattended
Never leave a lit candle unattended. It is important to keep an eye on candles at all times to prevent any potential hazards. Candles should not be burned for more than four hours at a time, as carbon will collect on the wick, causing it to "mushroom". This can lead to an unstable flame, excessive smoke, and soot release.
Trim the wick
Before lighting a candle, always trim the wick to 1/4 inch in length. Removing any excess wick helps prevent the flame from becoming too large and reduces the risk of the candle burning too hot. Trimming the wick also prolongs the life of the candle by preventing uneven burning, dripping, and sooting.
Avoid foreign objects in the wax pool
Always remove any debris, such as wick trimmings or matches, from the wax pool before lighting a candle. Foreign objects in the wax pool can add more fuel to the candle, increasing the risk of flare-ups or even small fires.
Allow the wax to melt edge-to-edge
When burning a candle for the first time, let it burn until the wax melts edge-to-edge, also known as a "full melt pool". This ensures that the candle burns evenly and optimally in the future. However, do not burn the candle for too long, especially if it is in a jar, as it can overheat and create a safety hazard.
Choose the right type of wick and wax
Different types of wicks and waxes burn at different rates and temperatures. For example, wooden wicks tend to burn hotter and faster than cotton wicks. Soy wax, for instance, burns slower than paraffin wax. Choosing the right combination of wick and wax ensures a safer and more enjoyable candle-burning experience.
By following these safety precautions, you can confidently enjoy the warmth and ambiance of candles while minimizing potential risks.

The best wicks for different waxes
When it comes to candles, there are many variables to consider to ensure optimal burning. The type of wax, fragrance load, dye type, and container diameter all play a role in determining the ideal wick. Here are some guidelines for choosing the best wicks for different types of waxes:
Soy Wax
Soy wax has a slower burn time compared to paraffin wax, so a thinner wick is generally recommended. TCR wicks are specifically designed for soy wax and other vegetable waxes like rapeseed or coconut. If you plan to burn soy wax candles for shorter intervals, such as 1 to 1.5 hours, a thicker wick is advisable to form a melt pool quickly. ECO wicks are also suitable for soy wax, especially for pillars and tall containers up to 7 inches in height.
Paraffin Wax
Paraffin wax burns faster than soy wax, so it may require a larger wick. Single-pour paraffin waxes, in particular, might need a wick that is one or two sizes larger. Wedo Eco wicks work well with paraffin wax, especially if you plan to use heavily fragranced or dyed candles.
Beeswax
Square wicks are considered the best choice for beeswax candles as they provide a strong flame. Beeswax candles burn slowly and smoothly but are not ideal for holding fragrances.
Palm and Coconut Wax
Wooden wicks are a good option for palm and coconut waxes. These wicks create a cozy atmosphere with their crackling sound. They are also suitable for blends, including beeswax.
Natural Waxes (Soy and Palm)
The ECO series wicks are specifically designed for natural waxes like soy and palm. These wicks are flat, coreless cotton braided with thin paper filaments for improved burn stability and reduced smoking. They are primed with vegetable wax, allowing your candles to be marketed as all-natural.
It's important to note that these recommendations are a starting point, and you may need to experiment with different wick sizes and types to find the perfect match for your specific candle. Always test burn your candles to ensure proper wick selection and follow safety guidelines for burn time and candle care.
