Candles are a great way to set the mood and add warmth to any space. While candles don't technically expire, their quality can degrade over time. The lifetime of a candle depends on several factors, such as the type of wax, storage conditions, size, and number of wicks. Natural waxes like beeswax, soy wax, and coconut wax tend to have longer burn times than paraffin wax. Interestingly, the colour of a candle can also impact its burn time. Several experiments have compared the burn rates of white and coloured candles, with some suggesting that coloured candles burn faster due to the presence of dyes, while others have found the opposite to be true.

What You'll Learn
Candle colour affects burn rate
Candle colour does have an impact on burn rate. While candles do not have an expiration date, their quality can degrade over time. The lifetime of a candle depends on the type of wax used, how it is stored, and its size. Natural candles made from beeswax, soy wax, or coconut wax tend to have longer burn times than those made from paraffin wax. Paraffin candles can last almost indefinitely when stored properly, whereas soy candles are best used within a year or two.
The rate of burning, or "burn time", depends on the size of the candle, the type of wax, and the number of wicks. A larger candle with more wicks will burn faster than a smaller candle with one wick. The thickness of the wick also determines the burn time.
Some sources suggest that white candles burn slower than coloured candles. This is because coloured candles contain dyes, or additional chemicals, that cause the candle to burn at a higher temperature and therefore burn out quicker. However, the results of a science fair project testing this hypothesis found that, in fact, the white candle burned faster than the coloured candle.
To extend the life of a candle, it is recommended to store candles away from direct sunlight and other harsh lights, in a dark, cool place, and avoid areas with high humidity, moisture, or sudden changes in temperature.

White candles burn slower
The lifetime of a candle depends on several factors, including the type of wax used, the size of the candle, the number of wicks, and how it's stored. While candles don't have an expiration date, their quality can degrade over time, and they can become difficult to light after being stored for several years.
Some sources suggest that white candles burn slower than coloured candles. This is because coloured candles contain dyes, which are essentially chemicals that make the candles burn hotter and quicker. However, other sources suggest that white candles burn faster than coloured candles, as the lack of dye allows them to burn more smoothly.
One experiment aimed to test this hypothesis by burning white and coloured candles for two minutes and measuring the difference in height before and after burning. The results showed that the coloured candles burned slightly faster than the white candles. However, another similar experiment reached the opposite conclusion, finding that white candles burned faster.
It's important to note that the results of these experiments may vary depending on the specific brands and sizes of the candles being tested. Additionally, the thickness of the wick can also affect the burn time of a candle, and this may vary even among candles of the same brand and size.
To extend the life of a candle, it's recommended to store it in a dark, cool place away from direct sunlight, harsh lights, high humidity, moisture, and sudden temperature changes.

Coloured candles have shorter lifespans
While candles don't have an expiration date, their quality can degrade over time. Candles with coloured wax might fade, especially if exposed to UV light. This is due to the dyes mixed into the wax oxidising and degrading. Therefore, it is recommended to store candles in a dark place, away from direct sunlight or bright indoor lights.
The lifetime of a candle depends on the type of wax used and how it is stored. Certain types of candles, like paraffin candles, can last almost indefinitely when stored properly. Other types, like soy candles, are best used within a year or two.
However, it is important to note that the thickness of the wick also plays a role in determining the burn time of a candle. Additionally, the size and shape of the candle will also impact how long it lasts.
To summarise, coloured candles have shorter lifespans due to the presence of dyes, which cause them to burn faster and hotter. To prolong the lifespan of coloured candles, it is recommended to store them away from direct sunlight and in a cool, dry place.

Candle storage impacts longevity
While candles don't have an expiry date, their longevity depends on their size, composition, and storage. Proper candle storage ensures they remain in optimal condition, retaining their scent and burning properties.
Firstly, candles should be stored in a cool, dry place, away from direct sunlight and heat sources like radiators and stoves. Heat and humidity can soften candles, causing them to lose their shape and burn unevenly. A consistent temperature preserves the wax structure and fragrance. Additionally, prolonged exposure to sunlight can cause colour fading in candles.
Secondly, keeping candles covered helps maintain their quality. For jarred candles, keeping the lid on prevents dust accumulation and protects the fragrance. This is especially important in areas with fluctuating temperatures, where the wax can undergo "blooming", resulting in a white, powdery appearance on the surface due to wax crystallization.
Finally, storing candles in a dark place is essential. Prolonged exposure to light can degrade the scent oils and affect the wax's consistency. By following these simple storage tips, you can prolong the life of your candles, ensuring they burn efficiently and retain their fragrance.
In summary, proper candle storage is key to maintaining the quality and longevity of your candles. By storing them in a cool, dry, dark place, away from direct sunlight and heat sources, you can prevent issues such as discolouration, warping, and scent loss, ensuring your candles remain in optimal condition for as long as possible.

Natural waxes burn longer
Natural wax candles, such as those made from soy, beeswax, or coconut oil, offer some of the cleanest and most luxurious burning experiences. However, due to the natural oils they contain, these candles typically last between one and two years before starting to show signs of rancidity. To extend the lifespan of natural wax candles, it is important to store them properly.
Natural wax candles are susceptible to degradation from sunlight and extreme temperatures. Therefore, it is recommended to store them in a cool, dark, and dry place, such as a closed cabinet or closet, to maintain their quality and fragrance. Additionally, storing candles in airtight containers or using candle toppers can help preserve their scent.
Compared to natural wax candles, paraffin wax candles have a longer shelf life and can last up to five years or even indefinitely when stored properly. However, fragrance retention in paraffin wax candles may begin to diminish after two years.
While natural wax candles may have a shorter lifespan than paraffin wax candles, they are known for providing a cleaner and more luxurious burning experience. Proper storage practices can help extend the life of natural wax candles, ensuring optimal burn quality and fragrance enjoyment.

Frequently asked questions
The lifetime of a candle depends on its size, the type of wax used, the number of wicks, and how it's stored. Natural waxes like beeswax, soy wax, and coconut wax tend to have longer burn times than paraffin wax.
Some sources suggest that white candles burn slower than coloured candles because the dyes in coloured candles contain chemicals that make them burn quicker. However, other sources claim that white candles burn faster due to the chemicals present in them.
To extend the life of your candle, store it in a cool, dark place away from direct sunlight, harsh lights, high humidity, moisture, and sudden temperature changes. It's also recommended to burn your candles within a year of unpacking them.
Scented and unscented candles have the same burn time. However, scented candles may begin to lose their fragrance over time due to the evaporation of fragrance oil molecules.
