Candles are synonymous with comfort, luxury, and relaxation. However, they can degrade over time. The first type of degradation to occur in a candle is scent degradation, which happens because molecules of fragrance oil evaporate from the wax into the air, even when the candle is not burning. This can be accelerated by exposure to sunlight. Colour degradation can also occur, especially in candles displayed in a place with direct sunlight. Burning a candle for too long can cause carbon to collect on the wick, leading to an unstable flame and potential fire hazards. To prevent this, candles should not be burned for longer than four hours at a time and should be stored in a cool, dark, and dry place.

What You'll Learn
Scented candles lose their fragrance over time
Scented candles do lose their fragrance over time, but there are ways to delay this process and ensure your candles retain their scent for longer. Firstly, it is important to understand that candles do not have a hard expiration date like food, but they do degrade over time. The rate of degradation depends on various factors, including the type of wax, fragrance, fragrance load, age, and storage conditions.
One of the main reasons scented candles lose their fragrance is due to the constant evaporation of fragrance oil molecules from the wax into the surrounding air, even when the candle is not burning. This process, known as scent degradation, is the first type of degradation to occur in a candle. To delay scent degradation, it is recommended to store candles in a cool, dark, and dry place with the lid secured to slow down the evaporation of fragrance oils.
Additionally, exposure to UV light and heat over time can cause the colour of the wax to fade and the candle to discolour, affecting its overall appearance. To prevent this, avoid storing candles in direct sunlight and opt for candles with UV protectant additives mixed into the wax.
The lifespan of a scented candle can vary, but most candles generally last around 12 to 16 months when properly stored. To get the most out of your scented candle, it is recommended to use it within a year of purchase. Burning a candle for too long can also affect its performance and fragrance throw, so it is important to follow the manufacturer's instructions and burn candles for no longer than three to four hours at a time.
By understanding the factors that contribute to scent degradation and taking the necessary steps to mitigate them, you can prolong the fragrance of your scented candles and enjoy their aromatic benefits for a longer period.

Coloured candles fade
Coloured candles can lose their vibrancy over time, especially when exposed to UV light or direct sunlight. The dyes mixed into the wax can oxidise and degrade, causing the colour to fade. This process can be slowed down by storing candles in a cool, dark, and dry place, away from excessive heat and light. Some candle makers also add UV protectant additives to the wax, which can help to preserve the colour.
The degree of colour degradation will depend on the amount and type of light exposure, as well as the type of dye used in the wax. Candles displayed as decorative pieces may start to fade faster than those stored away.
It is worth noting that while colour degradation can affect the appearance of a candle, it does not impact its ability to burn or its fragrance. However, candles can also experience scent degradation over time, as the fragrance oils evaporate from the wax, even when the candle is not burning.
To ensure the strongest fragrance, it is recommended to burn candles within a year of purchase. Proper candle care and storage can help prolong the life of a candle and maintain its colour, scent, and burning properties.
Additionally, factors such as wick maintenance, burn time, and environmental conditions can influence the overall lifespan of a candle. Trimming the wick and avoiding burning for longer than four hours at a time can help prevent the wick from mushrooming and producing a dangerously large flame. Storing candles away from drafts, open windows, and crowded areas can also ensure a more even burn and prolong their use.

Candles should be burned for 3-4 hours initially
To prevent this, always follow the manufacturer's instructions and allow the candle to cool for at least 2 hours before relighting. It is also important to trim the wick to 1/4 inch before lighting the candle and to ensure that any debris, such as wick trimmings or matches, is removed from the wax pool. This will help prolong the life of your candle and prevent uneven burning, dripping, flaring, and sooting.
Additionally, the storage of candles is crucial to maintaining their quality over time. Candles should be stored in a cool, dark, and dry place, away from direct sunlight and sources of moving air, such as fans or open windows. Prolonged exposure to sunlight can cause the colour and fragrance of the candle to fade or discolour. It can also cause the wax to warp.
Finally, it is important to note that candles do not have a hard expiration date, but they can degrade over time. Scented candles will lose their fragrance, and coloured candles may experience colour degradation due to exposure to UV light. Therefore, it is recommended to use and replace fragranced candles frequently to avoid deterioration in performance and appearance.

Wicks should be trimmed to 1/4 inch
Candles are a great way to create a cosy atmosphere, but they require care and attention to ensure they burn effectively and safely. One of the most important things to remember is to always trim the wick to 1/4 inch before lighting. This is because wicks that are left too long can cause a number of problems.
Firstly, a long wick can lead to uneven burning, causing the candle to drip and flare, and creating unsightly black marks on the glass. Trimming the wick helps to prolong the life of your candle, with some sources claiming that it can burn up to 25% longer if the wick is kept trimmed. Trimming the wick also helps to prevent "mushrooming", which occurs when carbon builds up on the wick, causing it to become unstable and produce a dangerously large flame. This can be extremely hazardous, particularly if the candle is left unattended or is near flammable materials.
In addition to safety concerns, a long wick can also affect the fragrance of the candle. When the wick is too long, the candle will burn more quickly, reducing the overall burn time and impacting the strength of the fragrance. Trimming the wick helps to ensure an even burn and maximises the fragrance diffusion.
Finally, keeping the wick trimmed also helps to prevent debris from falling into the wax pool, which can add fuel to the candle and cause the flame to flare up or even start a small fire. Therefore, it is clear that trimming the wick to 1/4 inch is an essential step in candle care, helping to ensure a safe, effective, and enjoyable burning experience.

Candles should be stored in a cool, dark place
Candles are a great way to fill your home with comfort, luxury, and relaxation. However, they do not last forever and will degrade over time. To ensure your candles last as long as possible, it is important to store them correctly. Candles should be stored in a cool, dark place.
Storing candles in a cool, dark place will help to preserve the colour and scent of the candle. Scented candles will lose their fragrance over time, and the longer you store them, the less scent they will produce when you eventually burn them. This is because fragrance molecules are constantly evaporating from the wax into the air, even when the candle is not burning. The same is true of coloured candles, which will fade over time due to exposure to UV light.
By storing your candles in a cool, dark place, you can slow down the evaporation of fragrance molecules and minimise exposure to UV light, thereby prolonging the life of your candle. A cool temperature will also help to prevent the wax from melting or warping, which could ruin the structure of the candle.
It is also important to keep candles away from sunlight, flames, and other sources of heat or open flames. This includes keeping them away from fans, air conditioners, open windows, or crowded areas with people walking back and forth, as moving air can disturb the flame. In addition, candles should be stored away from highly flammable materials such as silk, cotton, linen, and rayon.
Finally, it is recommended to keep candles in their original packaging when not in use, and to store them away from children, pets, or swinging doors that could knock them over. By following these storage guidelines, you can help to extend the lifespan of your candles and ensure they are safe to use.
