Burning a candle is easy, but there are several candle care and safety guidelines to follow to extend the life of your candle, prevent unsightly soot and tunneling, and burn your candle efficiently. Before lighting a candle, it is important to trim the wick to 1/8-1/4 inch and remove any debris from the wax pool, such as wick trimmings or matches. This is because wicks that are left long or crooked can cause uneven burning, dripping, flaring, and sooting. Additionally, any debris will add more fuel to the candle than intended, which can cause the flame to unexpectedly flare up or even start a small fire. After lighting the candle, it is important to let it burn until the top layer of wax melts to the edges of the vessel, which usually takes around two hours. This will help to extend the life of the candle by preventing candle tunneling. It is recommended that candles are not burned for more than 2-5 hours at a time, and that they are extinguished manually.

Before lighting: trim the wick and check for debris
Trimming the wick of a candle is an essential part of candle care. Before lighting a candle, always trim the wick to ¼ inch and remove any debris left in the wax pool, such as wick trimmings or matches. Any debris will add more fuel to the candle than it is designed to handle. Too much fuel can cause the flame to unexpectedly flare up or even start a small fire near the candle flame. Wicks that are left too long can cause uneven burning, dripping, flaring, sooting, excessive smoke, and even a fire hazard. Trimming wicks will help prolong the life of your candle. Your candles will burn up to 25% longer if you trim the wick every couple of hours.
The candle wick works by capillary action, drawing ("wicking") the melted wax or fuel up to the flame. When the liquid fuel reaches the flame, it vaporizes and combusts. The candle wick influences how the candle burns. Important characteristics of the wick include diameter, stiffness, fire resistance, and tethering. A candle wick is typically made from braided cotton, but other materials such as paper or zinc are sometimes used to help the wick stay upright.
If you are using a candle for the first time, it is especially important to trim the wick before lighting it. This will ensure that the candle burns evenly and cleanly. It is also important to trim the wick every couple of hours to maintain a clean and efficient burn.
In addition to trimming the wick, there are a few other things to keep in mind before lighting a candle. Firstly, always allow the candle to cool completely before lighting it again. Burning a candle for too long can cause carbon to collect on the wick, leading to an unstable flame and excessive smoke. It is recommended that candles do not burn for longer than four hours and that they are allowed to cool for at least two hours before relighting. Secondly, avoid burning candles near fans, open windows, or crowded areas, as moving air can disturb the flame and cause black marks on the glass. Finally, always store candles in a cool, dry place to keep them clean and protect the wax and fragrance.

Burning time: limit to 2 hours, no more than 4 hours
Burning a candle is a great way to set a mood or fill your space with a pleasant fragrance. However, it is important to be mindful of the duration for which a candle is left burning. The ideal burn time for a candle is a maximum of four hours, but it should not burn for longer than two hours without being extinguished and relit. This is to ensure safety and the best performance from your candle.
When burning a candle, it is important to keep in mind the potential fire hazards associated with prolonged burning. If left unattended, a candle can burn down to the bottom of the wick, creating a fire hazard. Additionally, carbon build-up can occur if a candle is burned for longer than four hours, causing the wick to become unstable and the flame to get too large. This can lead to wax tunneling, soot damage, and even damage to the candle container.
To optimise the burn time and performance of your candle, it is recommended to trim the wick to 1/4 inch before lighting it. This helps prolong the life of the candle and ensures a cleaner burn. It is also important to remove any debris, such as wick trimmings or matches, from the wax pool. Debris can add more fuel to the candle, causing the flame to flare up or even start a small fire.
The first burn of a new candle is the most critical. It is recommended to let the candle burn for about 3 to 4 hours the first time to ensure the wax melts all the way to the edges of the jar or container. This establishes a "'memory ring,' ensuring that the candle burns evenly in future uses. Failing to achieve a full melt pool during the first burn can result in tunneling, where the candle burns down the centre, wasting wax on the sides.
In summary, to enjoy your candle safely and optimally, limit the burn time to 2 hours, but no more than 4 hours at a time. Always ensure you follow the manufacturer's instructions and take the necessary precautions to prevent any potential hazards.

Extinguishing: use a candle snuffer, not your breath
When extinguishing a candle, it is recommended to use a candle snuffer instead of blowing it out with your breath. A candle snuffer is typically a small metal cup at the end of a long handle. Using a snuffer is safer because it cuts off the oxygen supply to the flame, whereas blowing it out can cause splashed wax. The hot liquid wax can cause skin burns if it comes into contact with skin.
Candle snuffers have been used for centuries, dating back to when candles were the primary source of lighting before electric lights were invented. They are still commonly found in churches that use large candles. Snuffers can also be decorative, adding a touch of elegance to your candle ritual.
In addition to safety and practicality, using a candle snuffer can also enhance your candle's performance and longevity. Blowing out a candle can cause the wick to become charred, which inhibits proper burning and produces black smoke. By using a snuffer, you avoid this issue and help maintain a clean, well-functioning wick.
Finally, using a candle snuffer is a more elegant and sophisticated way to extinguish a candle. It allows you to gently and quietly put out the flame, preserving the ambiance and atmosphere created by the candle's soft glow. Whether you're enjoying a romantic dinner or a relaxing bath, using a candle snuffer ensures that the mood isn't interrupted by the loud blow of extinguishing the flame.

Re-lighting: wait 2 hours, until wax cools
When relighting a candle, it is important to wait for the wax to cool. In general, it is recommended that candles are allowed to cool for at least two hours before being relit. This is an important safety precaution as it helps to prevent accidents and ensures the candle burns efficiently.
Allowing the wax to cool completely before relighting helps to prevent the build-up of carbon on the wick, which can lead to "mushrooming". This is when the wick becomes unstable and produces a dangerously large flame. It also helps to prevent the candle from smoking and releasing soot. By waiting for the wax to cool and solidify, you can help ensure an even and stable burn.
The length of time it takes for candle wax to cool and harden can vary depending on the type of wax. For example, vegetable waxes like soy continue to harden throughout their life due to their polymorphic nature. Crystals continue to form in response to time and temperature, resulting in harder wax over time. On the other hand, waxes like paraffin reach almost full hardness within a day or two of pouring.
The curing process, which involves allowing candles to sit and harden, can also impact the cooling time. During this process, the wax continues to harden and stabilise, improving the quality of the burn. The length of the curing process can vary, typically ranging from 3 to 14 days or even longer, depending on the type of wax and fragrance used. Therefore, it is important to consider the specific characteristics of your candle when determining the appropriate cooling time before relighting.

Discontinuing use: when 1/4-1/2 inch of wax remains or when it extinguishes itself
It is important to discontinue the use of a candle when there is only a small amount of wax remaining – about a quarter to a half inch. This is because, at this point, the candle is nearing the end of its burn life and continuing to use it could be unsafe. Candles should never be burned right down to the very end. If you do, the wick and flame may come into contact with the surface the candle is sitting on, causing potential damage to the surface and possibly even a fire. This is especially true if the candle is in a container, as the container can get extremely hot and cause a fire hazard.
Additionally, if a candle goes out by itself, this is a sure sign that it should not be relit. A candle that self-extinguishes has likely burned long enough and needs to be replaced. This could be due to a number of factors, such as an improperly trimmed wick, a draft in the room, or a lack of adequate ventilation. If a candle is allowed to burn for too long, it can cause the wick to move off-center, leading to an uneven burn and excess soot.
It is also worth noting that a candle that has burned down to this level will likely have a reduced burn time during subsequent uses, as the size of the flame will need to be smaller to avoid excessive heat and soot. Discontinuing use at the appropriate time helps to ensure the optimal performance and longevity of your candle, as well as maintaining safety.
By following these guidelines, you can ensure that your candles last longer, burn more efficiently, and, most importantly, do not pose a safety risk. Proper candle care and maintenance are essential to getting the most out of your candles while also ensuring a safe and enjoyable experience.

Frequently asked questions
Candling is a method used to check if an egg is fertile and developing properly. It involves shining a bright light through the egg to see what’s inside without cracking it open.
It is recommended to candle at least three times during incubation. The first candling should take place on day seven to check for early signs of life. The second candling can be done on day 10. The third candling can be done on day 20, when the chick is preparing to hatch.
You can candle your eggs every day if you like. However, it is best to keep the eggs outside of the incubator for no more than 30 minutes.
When candling eggs, look for veins and blood vessels that continue to grow and spread. A fertile egg will show a small dark spot (the embryo) with red veins branching out and a visible air sac. If there is no development, the egg is likely infertile.
