Candles are a great way to add ambiance to a room, with their soft glow, warmth, and fragrance. But how long do they last? The answer depends on several factors, including the type of wax, the number of wicks, and the size of the candle. The burn time of a candle, or the amount of time it can stay lit, can vary from 55 hours for an 8-ounce candle to up to 80 hours for larger candles. The type of wax used is a significant factor in a candle's longevity, with organic, vegetable-based waxes like soy and coconut having shorter shelf lives than paraffin and beeswax candles, which can last almost indefinitely when stored properly. Additionally, proper candle care, such as trimming the wick and storing in a cool, dark place, can extend the life of your candle. While candles don't typically expire, their scent and color can degrade over time, so it's best to use them within the first year of purchase to enjoy their full fragrance and aesthetic experience.

What You'll Learn
Candle burn time depends on size, wax type, and wicks
The burn time of a candle depends on several factors, including its size, the type of wax used, and the number and size of wicks.
Candles come in various sizes, from small votives to large jar candles. The size of a candle determines how long it will burn. Larger candles, typically those over 12 ounces, will burn longer per ounce than smaller candles. For example, a large candle may burn for five to eight hours per ounce, while a smaller candle may only burn for four to seven hours per ounce.
The type of wax used in a candle also affects its burn time. Candles are typically made with natural, synthetic, or blended wax. Natural waxes, such as soy, coconut, and beeswax, tend to have a shorter shelf life and may need to be used within a year or two. On the other hand, synthetic waxes like paraffin can last almost indefinitely when stored properly. The melting point of the wax is also a factor in burn time; a higher melting point means the candle will take longer to melt, resulting in a longer burn time.
The number and size of wicks in a candle also influence its burn time. A candle with multiple wicks will burn faster than one with a single wick. Similarly, a candle with a large wick will burn more quickly than one with a small wick. Trimming the wick to the recommended length of between one-eighth and one-quarter of an inch can help prolong the burn time of a candle by up to 25%.
In addition to these factors, the burn time of a candle can also be affected by environmental factors such as air movement, oxygen levels, temperature, and the material of the wick. Proper candle care and storage can also help extend the burn time and overall lifespan of a candle. It is recommended to store candles in a cool, dark, and dry place, away from direct sunlight and harsh lights, to preserve their fragrance and prevent discolouration.

Trim candle wicks to prolong life
The life of a candle goes beyond its burn time. Proper candle care is essential to prolonging the life of your candle, and one of the most important steps is trimming the wick.
Trimming your candle wicks regularly is crucial for several reasons. Firstly, it ensures a clean and even burn. When candle wicks are left long or untrimmed, they can cause uneven burning, dripping, flaring, and sooting. This can lead to the formation of debris near the base of the wick, which can be picked up by the flame and cause the candle to burn hotter and faster than intended. By trimming the wicks, you prevent this debris from forming and maintain a healthy flame height, typically between 1/2 inch and 1 inch.
Secondly, wick trimming helps to prolong the life of your candle. By preventing the flame from becoming too tall, you reduce the risk of fire hazards and prevent the candle from burning too quickly. Trimming the wick also helps to maintain the fragrance of the candle. When the flame is too high, it can burn off the essential and fragrance oils faster, resulting in a weaker scent throw in the later stages of the candle's life.
To trim your candle wicks effectively, use a wick trimmer or another cutting tool to cut the wick down to a length of about 1/4 inch above the wax before lighting each time. It is best to trim the wick before the candle is lit, as the wax is still solid, making the process easier. Avoid trimming the wick immediately after extinguishing the candle, as the jar will be too hot to handle. Instead, wait for the candle to cool down to room temperature before trimming.
By following these simple steps and maintaining a consistent trimming routine, you can extend the life of your candle, enjoy a clean and even burn, and maximize the fragrance experience.

Store candles in a cool, dark place
Candles are a great way to create a warm and cosy atmosphere, but they require proper care and storage to ensure their longevity. One of the most important things to remember is to store your candles in a cool, dry, and dark place.
Firstly, let's talk about temperature. Storing candles in a cool place is crucial to maintaining their shape and fragrance. Excess heat can cause the wax to soften, leading to potential warping or melting. The ideal temperature for candle storage is below 80°F (26.7°C). The colder the temperature, the better, but avoid storing candles in the freezer as this can damage the wick and cause the wax to crack.
Now, let's discuss humidity and moisture. Candles are sensitive to changes in humidity and moisture levels. Avoid storing them in areas with high humidity, such as bathrooms or kitchens, as this can affect the quality of the wax and fragrance. Keep them away from sources of moisture, such as sinks or leaky pipes.
Next up is light exposure. Direct sunlight and harsh indoor lighting, such as spotlights or desk lamps, can cause oxidation and degradation of the dyes and fragrance oils in the wax. This leads to faster fading of both the scent and colour of your candles. So, it's best to opt for dark storage spaces or use candle toppers, lids, or elegant bell cloches to protect your candles from light exposure when not in use.
Additionally, here are some extra tips to ensure the longevity of your candles:
- Keep them away from direct sources of heat like radiators or heating vents.
- Store them in a dust-free environment to prevent debris from accumulating on the wax.
- Avoid placing them in areas prone to sudden temperature changes.
- Group and organise your candles based on size, type, and shape to make them easier to locate and create a beautiful arrangement.
- Trim the wicks to the appropriate length before each use to ensure even burning and prolong the life of your candles.
- Avoid burning candles for too long in one session. It's recommended to limit burn time to around 2 hours and allow the candles to cool completely before relighting.

Candles can be safely burned after years of storage
To ensure the longevity of your candle, it is important to store it correctly. Keep candles away from direct sunlight and other harsh lights, as exposure to UV light can cause the dyes in the wax to oxidize and degrade, resulting in colour degradation. Store candles in a dark, cool, and dry place to protect the wax and fragrance. Avoid areas with high humidity, moisture, or sudden changes in temperature. Using a candle topper or a glass cloche can also help to preserve the fragrance for longer.
When it comes to burning your stored candle, always follow the manufacturer's instructions and safety warnings. Trim the wick to between 1/8 and 1/4 of an inch before lighting to prolong the life of your candle and ensure a cleaner burn. Avoid burning a candle for longer than four hours at a time to prevent carbon buildup on the wick, which can make it unstable and produce a dangerously large flame. Allow the candle to cool completely before lighting it again.
While older candles may not have the same fragrance intensity or colour as when they were first purchased, they can still be safely burned and enjoyed. However, it is important to note that highly fragrant candles have a lifespan of 6 to 12 months, and the longer an unlit candle is stored, the less scent it will produce when burned. Additionally, older candles may burn less evenly and may not deliver the same fragrance throw as a new candle.

Candle colour and scent degrade over time
Candles can lose their scent over time, as fragrance oils break down, causing the aroma to be less noticeable when the candle is burned. This process is similar to how a perfume's scent fades when exposed to sunlight. Proper storage and care can extend a candle's scent life. Exposure to air, heat, and light can cause fragrance oils to degrade, so it is best to store candles in a cool, dry, and shaded place, away from direct sunlight. Additionally, candles with lids should be kept covered when not in use, and those without lids can be stored in airtight containers.
The type of wax and quality of fragrance oils also affect scent retention. Soy wax, for example, is known for its slow burn and gradual fragrance release, while paraffin wax has a stronger initial scent but may not last as long. High-quality fragrance oils are crucial for scent longevity, as cheaper oils may evaporate or lose potency more quickly. Natural fragrances tend to degrade faster than synthetic ones, but a combination of natural essential oils and perfume-quality fragrances can create a luxurious and long-lasting scent.
Candle colour can also fade over time, mainly due to exposure to UV light, which causes the dyes in the wax to oxidize and degrade. Storing candles in a dark place can help prolong their colour, but if displayed in a lit area, the colour may start to fade faster. The type of dye used in the wax also influences colour degradation, and some candle makers add UV protectant additives to slow down this process.
While candles do not have a hard expiration date, they certainly degrade over time. Proper storage and care can help extend their lifespan, allowing you to enjoy their fragrance and beauty for longer.
