Candles are a popular home accessory, but how long do they last? While candles don't have a hard expiration date, their quality does degrade over time. The longevity of a candle depends on several factors, including the type of wax, the presence of additives, the number of wicks, storage conditions, and whether it has been lit. Paraffin wax candles, for example, can last almost indefinitely when stored properly, while soy and coconut wax candles are best used within a year or two as they are more prone to breaking down. To extend the life of a candle, it is recommended to store it in a cool, dry, dark place, away from direct sunlight, and to use a candle topper or a glass cloche to preserve the fragrance.

What You'll Learn
Candle burn time depends on size, wax type, and wicks
The burn time of a candle depends on various factors, including its size, the type of wax used, and the number of wicks it has. While candles do not have a definite expiration date, their quality does degrade over time, and their lifespan can vary significantly.
Regarding size, a larger candle will naturally have a longer burn time than a smaller one. For example, a 12 oz luxury candle from the Harlem Candle Company has an average burn time of approximately 80 hours.
The type of wax is a crucial factor in determining a candle's burn time. Organic, vegetable-based waxes like soy, and coconut are more prone to breaking down over time, with a recommended burn time of around one to two years. On the other hand, paraffin wax candles, which are made from low-grade petroleum wax, can last almost indefinitely when stored properly. This is because paraffin wax is highly stable and filled with synthetic additives and preservatives. While paraffin wax candles may not offer the same luxurious burning experience as natural wax candles, their longevity makes them a popular choice.
Additionally, the number of wicks in a candle impacts its burn time. A candle with multiple wicks will burn faster and have a shorter lifespan than a candle with a single wick. It is important to note that wicks require maintenance for optimal burn time. Trimming the wick to between an eighth and a quarter of an inch is essential for a long-lasting candle.
To extend the lifespan of your candles, proper storage is crucial. Keep them away from direct sunlight, harsh lights, and areas with high humidity or sudden temperature changes. Store candles in a dark, cool, and dry place, such as a closed cabinet or closet, to preserve their fragrance and colour.

Paraffin candles can last indefinitely with proper storage
While candles do not have a hard expiration date, they do degrade over time. The lifetime of a candle depends on the type of wax used and how it is stored. Paraffin candles, for example, are made from low-grade petroleum wax and are extremely stable. They can last almost indefinitely when stored properly.
To ensure the longevity of paraffin candles, it is important to protect them from certain factors that can cause degradation. Firstly, sunlight and harsh lights can cause discolouration and fragrance dissipation. Therefore, it is recommended to keep candles away from direct sunlight and harsh lights, and to use candle toppers or glass cloches to preserve the fragrance. Additionally, storing candles in dark and cool places, such as closed cabinets or closets, can help maintain their quality.
Humidity and moisture are other factors that can impact the longevity of paraffin candles. It is best to avoid storing candles in areas with high humidity or moisture, such as bathrooms. Moreover, sudden changes in temperature can affect the consistency of the wax. Hence, areas with radiators or vents are not ideal for candle storage.
While paraffin candles can last a long time, the scent and quality of the burn may diminish over time. This is due to the gradual evaporation of fragrance oil molecules from the wax, even when the candle is not burning. As a result, the fragrance may weaken or change, and the colour may fade. However, with proper storage, the longevity of paraffin candles can be significantly extended.

Soy and coconut candles are best used within 1-2 years
While candles do not have a hard expiration date, their longevity depends on the type of wax used and how they are stored. Soy and coconut candles, for instance, are organic, vegetable-based waxes that are more susceptible to degradation over time. Therefore, they are best used within 1-2 years of purchase.
Soy and coconut candles offer some of the cleanest and most luxurious burning experiences. However, their organic and vegetable-based waxes are more prone to breaking down than other types of wax. Once they start to degrade, the wick may become clogged, making the candle difficult to light.
To extend the life of your soy and coconut candles, proper storage is essential. Keep them away from direct sunlight and other harsh lights, as sunlight is an enemy to just about any candle, especially those made with essential oils, natural fragrances, and organic waxes. Store them in a dark, cool place, such as a closed cabinet or closet, and avoid areas with high humidity or moisture, such as bathrooms. Additionally, avoid areas with sudden temperature changes, such as those near radiators or vents.
Using your soy and coconut candles within the first 1-2 years of purchase ensures that the scent stays strong and doesn't deteriorate. It is also when the wax is at its healthiest. To maintain the fragrance of your candles, you can use a candle topper or a glass cloche. Additionally, storing them in airtight containers or glass jars with airtight lids will help preserve the fragrance for longer.
By following these storage guidelines and using your soy and coconut candles within the first 1-2 years, you can ensure that they burn efficiently and provide the luxurious experience they promised when you first purchased them.

Candles should be stored in a cool, dark place
Candles do not have a hard expiration date, but they do degrade over time. The lifetime of a candle depends on the type of wax used and how it is stored. While paraffin candles can last almost indefinitely when stored properly, soy and coconut candles are more prone to breaking down over time and are best used within a year or two.
To ensure your candles last as long as possible, they should be stored in a cool, dark place. Keep them away from direct sunlight and other harsh lights, as sunlight is an enemy to just about any candle and can cause discolouration. Avoid storing candles in areas with high humidity or moisture, such as bathrooms, and avoid areas with sudden changes in temperature, such as near radiators or vents.
To preserve the fragrance of your candles for longer, use a candle topper or a glass cloche. Glass jar candles typically come with airtight lids, which keep their fragrance from evaporating into the air over time. While candles won't pose a threat if lit past their shelf life, they may burn less evenly and may not deliver the same fragrance experience.
In addition to proper storage, there are other things you can do to make your candles last longer. Trimming the wick before using a new candle will help extend its life, and you should not burn a candle for more than four hours at a time to prevent carbon build-up on the wick.

Trim wicks and avoid long burn times to extend candle life
Candles do not have a hard expiration date, but they do degrade over time. The lifetime of a candle depends on factors such as the type of wax used, the presence of added dyes or fragrances, and how it is stored. Natural waxes like soy, coconut, and vegetable-based blends have a shorter shelf life, usually around one to two years, and are more prone to breaking down over time. On the other hand, paraffin and beeswax candles can last almost indefinitely when stored correctly.
To extend the life of your candle, it is important to trim the wicks regularly and avoid long burn times. Here are several reasons why:
Firstly, trimming the wicks helps to ensure an even burn and prevents candle tunneling. Candle tunneling occurs when only a small portion of the wax around the wick melts, creating a narrow, vertical tunnel in the centre of the candle. This can be caused by an untrimmed wick leading to a flame that is too hot. By trimming the wicks, you encourage the entire surface of the wax to melt evenly, resulting in a luxurious burning experience.
Secondly, trimming the wicks helps to maintain a healthy flame height. An untrimmed wick can lead to a flame that is too tall, which in turn causes the candle to burn too hot. This increased temperature accelerates the vaporization of the scent and wax, resulting in an uneven burn and excessive soot production. By trimming the wicks, you promote a steady and consistent flame that burns at the optimal temperature, reducing the amount of soot released into the air.
Thirdly, trimming the wicks helps to prolong the life of your candle by reducing the amount of debris that falls into the wax. As a candle burns, cotton and wood wicks can split, causing burnt pieces to break off into the wax. This debris can be picked up by the flame, causing the candle to burn faster and hotter than intended. By regularly trimming the wicks, you prevent the formation of this debris and extend the overall burn time of your candle.
In addition to wick trimming, it is recommended to avoid burning candles for extended periods without interruption. To maintain good flame hygiene and prevent wick mushrooming, allow your candle to cool down to room temperature and trim the wick before relighting. As a general rule, burn your candle for one hour per inch of diameter, and trim the wick every four hours of burn time.
By following these simple steps of wick trimming and avoiding long burn times, you can significantly extend the life of your candle, ensuring an enjoyable and safe burning experience.
