Candles are a great way to add ambiance to a room, but how long do they last if they're not burned? The longevity of an unburned candle depends on several factors, including the type of wax, the presence of fragrance or colour, and storage conditions. Scented candles, for instance, may experience scent degradation over time due to the evaporation of fragrance oils, resulting in a weaker fragrance when burned. Similarly, coloured candles can fade when exposed to UV light, though this can be mitigated by storing them in dark places. While certain candles, like those made of paraffin wax, can last almost indefinitely, soy candles are best used within one or two years. Ultimately, while unburned candles may not have an expiration date, their quality can degrade over time, impacting their fragrance, colour, and burning experience.

Scented candles lose fragrance over time due to the evaporation of oil molecules
Scented candles are designed to release fragrance into the air, whether lit or unlit. However, the fragrance oils in scented candles are volatile, meaning they can easily evaporate at room temperature. This evaporation process is accelerated when the candle is lit, as the heat from the flame causes the wax to melt, releasing the fragrance oils into the air as a gas.
Even when a candle is not burning, some fragrance oil molecules in the wax are energetic enough to escape into the air. This process of scent degradation occurs very gradually and may be unnoticeable for the first six months to a year, depending on the type of wax and the quality of the fragrance oils used. The longer an unlit candle is stored, the less scent it will produce when burned.
To preserve the fragrance of an unburned candle, it is recommended to store it in a dark, cool place, away from areas with high humidity, moisture, or sudden changes in temperature. Additionally, using a candle topper or a glass cloche can help to extend the life of the fragrance. While candles do not have an expiration date, it is generally recommended to burn them within a year of purchase for the best experience.
The lifetime of an unburned candle also depends on the type of wax used. For example, paraffin candles can last almost indefinitely when stored properly, while soy candles are best used within one or two years. Exposure to UV light can also cause the colour of a candle to fade over time, so it is best to store candles away from direct sunlight or bright indoor lights.

Store candles away from sunlight to preserve colour and scent
Candles can be a beautiful addition to your home, providing ambiance, fragrance, and warmth. However, to ensure their longevity, it is essential to store them properly, especially when it comes to preserving their colour and scent.
Sunlight is one of the biggest contributors to candle degradation. The UV rays in sunlight cause the dyes in the wax to oxidize and degrade, resulting in colour fading. Even indoor lights can emit UV rays, although to a lesser extent than direct sunlight. Therefore, it is crucial to store candles away from direct sunlight to maintain their vibrant colours.
Additionally, fragrance oil molecules constantly evaporate from the wax into the air, leading to scent degradation over time. This process is accelerated by heat, so storing candles in a cool, dark place can help preserve their scent. Areas with high humidity or sudden temperature changes can also impact the fragrance and overall quality of the candle, so these should be avoided.
To further protect the colour and scent of your candles, consider using a candle topper or a glass cloche. These barriers provide an extra layer of protection from UV rays and can help slow down the evaporation of fragrance oils.
By following these storage guidelines, you can extend the life of your candles, ensuring they retain their colour and scent for a more enjoyable and sensory experience.

Paraffin candles can last indefinitely if stored properly
Therefore, it is recommended to store candles in a cabinet, closet, or drawer, as these locations typically maintain a consistent temperature and protect the candles from light exposure. It is also important to avoid placing candles near windows, heaters, or other sources of heat and humidity. For delicate or uniquely shaped candles, consider using bubble wrap or a soft cloth for additional protection.
To preserve the fragrance of a candle for a longer period, you can use a candle topper or a glass cloche. Additionally, storing candles in a dark place can help to slow the discoloration process. By following these storage practices, paraffin candles can be kept indefinitely.
It is worth noting that, while paraffin candles can last indefinitely, other types of candles, such as soy candles, are best used within one to two years. The lifetime of a candle depends on the type of wax used and how it is stored. Proper storage ensures optimal burning and helps to prolong the life of a candle.

Soy candles are best used within one or two years
Soy wax candles have a more powerful fragrance compared to other types of wax, such as paraffin wax. However, soy wax is more prone to breaking down over time due to its organic, vegetable-based composition. Proper storage is crucial to prolonging the life of a soy candle. It is best to avoid storing them anywhere warm, wet, or drafty, as soy wax can melt in hot environments, causing the scent to deteriorate.
To get the most out of a soy candle, it is recommended to burn it in short stints of a few hours to ensure an even burn. For safety reasons, candles should not be burned for longer than four hours at a time. Additionally, it is important to trim the wick before lighting to ensure a clean burn and prevent the wick from becoming clogged, which can make the candle difficult to light.
While soy candles are best used within one to two years, they do not have a hard expiration date and can be enjoyed for decorative purposes even after this timeframe. However, the colour and scent may fade over time, and the wax may become uneven or difficult to light. Proper candle care and storage can help extend the life of a soy candle and ensure it burns efficiently and safely.

An old candle may burn unevenly but is usually safe
Candles do not typically have an expiration date, but their quality can degrade over time. While they can last for years, it is recommended to use them within one to two years of purchase for the best experience. An older candle may burn less evenly, but it is usually safe to use.
The lifespan of a candle depends on the type of wax and how it is stored. Paraffin candles, for example, can last almost indefinitely when stored properly. In contrast, soy and coconut wax candles have a shorter shelf life of around one to two years. Natural waxes like soy and coconut offer some of the cleanest and most luxurious burning experiences.
Scented candles may lose their fragrance over time, even when unlit, due to the evaporation of fragrance oil molecules from the wax into the air. This process occurs gradually and can be slowed by storing candles in a dark, cool place away from direct sunlight and other sources of UV light, which can cause the colour of the wax to fade.
Candles made with lower-quality wax and wicks may produce a weaker flame when burned after several years. However, beeswax candles are known to last for several years, even centuries, as evidenced by candles found in sunken ships that burned beautifully once the wicks were dried out.
To extend the life of your candle, store it in optimal conditions and use a candle topper or a glass cloche to preserve its fragrance. Additionally, check the candle for dryness, yellowing, and discolouration, as these may indicate that the candle has degraded and will not burn as effectively.
