Candles are a great way to add ambiance and scent to a room. But do candles dry out? While candles do not have a hard expiration date, they can degrade over time. The lifetime of a candle depends on factors such as the type of wax, fragrances, and storage conditions. Paraffin and beeswax candles can last almost indefinitely when stored correctly, while soy and coconut candles are best used within a year or two. To prolong the life of your candles, it is important to store them in a cool, dry place, away from direct sunlight and heat sources. Additionally, trimming the wick and limiting burn time can help extend the life of your candles.

Candles don't expire, but they can lose their fragrance and colour over time
Candles do not have a hard expiration date and will not go bad like food does. However, they can degrade over time, becoming difficult to light or not burning properly. The lifetime of a candle depends on factors such as the type of wax, fragrances, and storage conditions. Organic, vegetable-based waxes like soy and coconut are more prone to breaking down over time, with soy candles typically having a shelf life of 1-2 years. On the other hand, paraffin and beeswax candles are more stable and can last almost indefinitely when stored correctly.
To preserve the life of your candles, it is important to store them properly. Keep them away from direct sunlight, harsh lights, and heat sources such as kitchen stoves or fireplaces. Store candles in a cool, dry environment, as heat can cause candles to bend, warp, and fragrance oils to go rancid. Additionally, use a candle topper or a glass cloche to help maintain the fragrance for longer.
To make your candles last longer, you can trim the wick regularly and limit their burn time. Alternating between different candles can also help prolong their burn time. While candles may not have a definitive expiration date, their fragrance and colour can fade over time. Candles with artificial fragrances tend to last longer than natural ones, as natural ingredients degrade over time. If your candles contain essential oils, it is advisable to use them sooner rather than later to avoid any stale or rotten smells.
Overall, while candles may not technically expire, their appearance and fragrance can diminish with time. Proper storage and care can help extend the life of your candles, allowing you to enjoy their light and scent for longer.

Store candles in a cool, dry place, away from direct sunlight
Candles do not have a hard expiration date, but they do degrade over time. To ensure they last as long as possible, it is important to store them correctly.
Firstly, candles should be kept in a cool place. Heat can cause candles to bend, warp, and stick together. It will also make fragrance oils go rancid. If you are storing taper or pillar candles, you can wrap each candle in plastic wrap or wax paper to help protect them from the heat.
Secondly, candles should be stored in a dry place. While moisture does not usually affect candle wax, it can get into the wick.
Thirdly, candles should be stored away from direct sunlight. Sunlight can cause candles to lose their colour. Brighter colours, such as reds and yellows, can turn into dull browns. Exposure to sunlight can also cause the candle wax to look oily and feel sticky.
Finally, candles should be stored away from other heat sources, such as kitchen stoves, fireplaces, radiators, vents, and electronic devices.

The type of wax used affects a candle's lifetime
The type of wax used in a candle has a significant impact on its longevity. While candles do not have a definitive expiration date, they do degrade over time, and the type of wax determines the rate and manner of this degradation.
Paraffin wax, for instance, is known for its longevity. When stored properly, paraffin candles can last almost indefinitely. They are less susceptible to breaking down, making them a stable option. On the other hand, organic, vegetable-based waxes like soy and coconut are more prone to degradation over time. Soy wax, in particular, has a shelf life of around two years when stored properly. This type of wax is denser than paraffin, which can make it more challenging to release fragrance. Additionally, soy wax may develop a frosted look over time, which can be mitigated by closely following heating and pouring guidelines during production.
Beeswax is another type of wax that shares similar longevity characteristics to paraffin. It can last almost indefinitely if stored correctly. However, it's important to note that the performance of candles made from non-natural waxes may noticeably decline over time.
The environment in which candles are stored also plays a crucial role in preserving their lifespan. High temperatures and humidity can accelerate the deterioration of wax. Therefore, it is recommended to store candles in a cool, dry, and dark place, away from direct sunlight and heat sources.
In summary, the type of wax used in a candle directly influences its lifetime. While some waxes like paraffin and beeswax can endure for extended periods, others like soy and coconut wax have shorter shelf lives. Proper storage conditions are also essential to maximise a candle's longevity, regardless of the wax type.

Trimming the wick increases burn time
Candles are a great way to add ambiance to any space. However, they can be a fire hazard if not properly cared for. Trimming the wick is an essential step in candle maintenance and can increase burn time by up to 25%. Here are some reasons why:
Preventing tunneling
Candle tunneling occurs when only a small portion of the wax around the wick melts, creating a narrow, vertical tunnel in the center of the candle. This is caused by a flame that is burning too hot due to an untrimmed wick. By trimming the wick, you ensure that the flame burns closer to the outer edges, allowing the entire surface of the candle to melt evenly.
Maintaining a consistent burn and maximising burn time
A long wick can generate too much heat, causing the wax to melt unevenly. Trimming the wick helps to maintain a consistent burn by keeping the flame at a healthy height. This, in turn, maximises the candle's burn time, allowing you to enjoy your candle for longer.
Reducing soot and indoor air pollution
Candle soot is produced when the fuel (wax) doesn't burn completely, releasing tiny carbon particles into the air. A longer wick produces more soot, which can contribute to indoor air pollution and be harmful to your health, especially if you have respiratory conditions. Regular wick trimming minimises soot production, improving the air quality in your home.
Preserving fragrance
Trimming the wick helps to prevent the candle from burning too hot, which can cause the fragrance to be released too quickly. By maintaining a consistent burn, you can ensure an even scent throw throughout the life of your candle.
Safety
A longer wick can cause larger flames, increasing the risk of fire. Trimming the wick helps to control the flame size, making it safer to burn your candle.
In conclusion, trimming the wick is a simple yet crucial step in candle care. It helps to increase burn time, improve performance, and create a safer and more enjoyable candle experience. By following these tips, you can maximise the lifespan of your candles and make the most of their beautiful light and fragrance.

Candles with artificial fragrances last longer than natural ones
Candles with artificial fragrances may last longer than natural ones, but it is essential to understand that this is not a given. The lifespan of a candle is influenced by several factors, including the type of wax, size, storage conditions, and fragrance concentration.
Firstly, the type of wax is crucial. Organic, vegetable-based waxes like soy and coconut are more prone to degradation over time, which can make the wick difficult to light. On the other hand, paraffin and beeswax candles are more stable and can last almost indefinitely when stored correctly. Therefore, the choice of wax can significantly impact the longevity of a candle, regardless of its fragrance type.
Secondly, the size of the candle matters. Larger candles tend to last longer than smaller ones. A small votive may burn for around 15 hours, while a large jar candle can last upwards of 60–100 hours, depending on its size and burn conditions.
Thirdly, storage conditions play a vital role in preserving the lifespan of a candle. To make your candles last longer, keep them away from direct sunlight and other harsh lights. Store them in a cool, dark, and dry place, avoiding areas with high humidity or moisture. Additionally, ensure they are not exposed to sudden temperature changes.
Lastly, the concentration of fragrance oils can impact burn time. Highly scented candles, whether artificial or natural, may burn faster due to the oils they contain. Therefore, it is not solely the type of fragrance but also its concentration that influences the lifespan of a candle.
In conclusion, while candles with artificial fragrances may have a longer lifespan due to the stability of certain wax types and the potential for higher fragrance oil concentrations, it is essential to consider the interplay of all the factors mentioned above. Proper storage conditions and the choice of wax are critical in ensuring that candles last as long as possible, regardless of their fragrance type.
