What You'll Learn
Larger candles have longer burn times
It's important to understand how long your candle will burn, both for safety and to ensure you get the most out of your purchase. Larger candles have longer burn times due to the greater amount of wax. The weight of a candle is a good indicator of its burn time. For example, a large candle of 12 ounces or more will burn for approximately 5 to 8 hours per ounce, or around 80 hours in total. However, it's not just about size; the shape and volume of the candle also play a role. Heavier candles, which contain more wax, will naturally burn longer.
The density of the wax can also affect how quickly it burns. Different types of wax have varying burn rates. For example, soy wax tends to burn slower and cooler, prolonging burn time, whereas paraffin wax usually burns faster. Beeswax is known for its slow, steady burn. The number of wicks in a candle also influences its burn time. A thicker wick burns more wax and thus shortens the candle's life. A candle with multiple wicks, such as those with five wicks, will last longer.
To get the most out of your candles, there are several care and maintenance tips you can follow to maximize their burn time. Firstly, always trim the wick to about 1/4 inch before lighting your candle. Wick trimming helps prevent soot buildup, ensures a cleaner burn, and controls larger flame sizes, reducing the faster rate at which the wax is consumed. Secondly, ensure the first burn lasts long enough to melt the wax all the way to the edges, creating a full melt pool. Repeat this every time you light the candle. Avoid burning your candle for short periods, as this doesn't give the wax enough time to melt evenly, leading to issues like candle tunneling. Lastly, place your candle in a location free from drafts, as air currents can cause uneven burning and faster wax consumption.

The type of wax affects burn rate
The type of wax used in a candle plays a crucial role in determining its longevity. While several factors influence how long a candle lasts, the type of wax remains central to its burn time.
Paraffin wax, derived from petroleum, is one of the most common types of wax used in candle-making due to its cost-effectiveness. However, paraffin wax tends to burn faster compared to other waxes because of its lower melting point, resulting in quicker wax consumption. On the other hand, natural alternatives like soy wax, made from soybean oil, offer a slower burn rate and can last up to 50% longer than paraffin candles. Soy wax also burns cleaner, producing less soot and toxins.
Beeswax is another natural wax known for its long burn time due to its high melting point. While beeswax candles are relatively expensive and challenging to work with, they offer a slow and steady burn. A 4oz beeswax candle with the right wick can burn for approximately 25 hours, providing excellent value for money.
Palm wax, rapeseed wax, and coconut wax are alternative wax options, but they burn at much lower temperatures. Coconut wax, for instance, is typically blended with other waxes to create solid candles as it is liquid at room temperature. The burning temperature of a candle can be estimated by checking its softness at room temperature. Harder waxes, like beeswax and paraffin wax, have higher melting points, contributing to longer-lasting candles.
In summary, the type of wax significantly affects the burn rate of a candle. While paraffin wax is widely used due to its affordability, it burns faster than other waxes. For longer-lasting candles, natural alternatives like soy wax and beeswax offer slower burn rates, reduced soot production, and extended burn times.

Candle care prolongs lifespan
The size of a candle does impact its burn time, with larger candles boasting longer burn times due to their greater amount of wax. However, candle care also plays a significant role in prolonging a candle's lifespan.
Trimming the wick
Trimming the wick to about a quarter of an inch before lighting the candle helps prevent soot buildup and ensures a cleaner and more controlled burn. A properly trimmed wick reduces the size of the flame, slowing the rate at which the wax is consumed.
Initial burn
The first burn is crucial in determining the lifespan of a candle. It is important to allow the candle to burn long enough for the wax to melt to the edges of the container, forming a full melt pool. This process prevents tunnelling, which occurs when a candle burns straight down the middle, leaving a ring of unmelted wax.
Regular wick trimming
Trimming the wick after burning a candle for a few hours prepares it for future use. After extinguishing the flame, let the candle cool down to room temperature, then use a wick trimmer to cut down the wick. This process should be repeated every four hours of burn time.
Avoid drafts
Air currents can cause uneven burning and faster wax consumption, so it is important to place candles in a draft-free location. Additionally, keep candles away from direct sunlight and other heat sources, as extreme heat can cause the wax to melt and sweat, reducing the candle's lifespan.
Storage
Proper storage is essential for prolonging the lifespan of candles. Keep candles in a cool, dry place, away from areas of high humidity or moisture. Store them somewhere dark, away from direct sunlight, and protect them from dust by covering them with a lid or cloche.

Multiple wicks increase longevity
The number of wicks in a candle plays a significant role in determining its longevity. While a candle will burn as long as it has at least one wick, multiple wicks can increase its efficiency, especially in large or oddly shaped candles.
When a candle burns, the flame melts the wax around the wick. The heat from the flame should be sufficient to melt the entire top layer of wax. However, in the case of large candles, the heat may not be enough to melt the larger volume of wax evenly. This results in candle tunnelling, where the candle burns down the middle, leaving unmelted wax around the edges.
By incorporating multiple wicks, the heat distribution becomes more even, ensuring a more uniform melting of the wax. This prevents the formation of holes around the wick and reduces wax wastage. Additionally, the brighter flame produced by multiple wicks enhances the candle's fragrance and illuminates larger spaces more effectively.
To maximize the benefits of multiple wicks, proper wick placement is crucial. Ideally, wicks should be positioned halfway between the centre and the outside edge of the container. A distance of at least 1.5 inches between wicks is recommended to avoid excessive heat and potential crowding in the container.
For square-shaped jars, four evenly spaced wicks are often optimal, while round jars typically accommodate up to three wicks without creating excessive heat. It is important to note that the number of wicks should be adjusted based on the size and shape of the container to ensure safe and efficient burning.

Storage conditions impact duration
Storage conditions have a significant impact on how long candles last. While some candles, like those made of paraffin wax, can last almost indefinitely when stored properly, others, such as soy candles, are best used within a year or two. Organic, vegetable-based waxes like soy and coconut are more prone to breaking down over time, which can lead to wick clogging and difficulty in lighting the candle.
To ensure the longevity of your candles, it is recommended to store them in a cool, dark place. Warm temperatures can cause candles to sweat, separate from their fragrance, and soften or even melt. Storing candles in a cool environment, preferably below room temperature, helps maintain their shape and scent. The ideal storage spot is an enclosed, dark, cool area, away from direct sunlight and other harsh lights, which can cause the colour and scent of the candle to fade.
It is also important to avoid areas with high humidity or moisture, such as bathrooms, and sudden changes in temperature, like those near radiators or vents. Additionally, keep candles away from sources of direct heat, including radiators, space heaters, and kitchen appliances. The colder the temperature, the better; you can even store candles in the fridge, but never in the freezer, as this can damage the wick and wax.
When it comes to candle placement, it is recommended to store them flat, especially in the case of taper candles, to prevent warping or damage. For pillar candles, if they are in glass jars, they can be stored upright; otherwise, they should be stored flat as well. Jar candles are also a good option as they don't spoil as easily and can be safely stacked.
Lastly, consider fire safety and keep candles out of the reach of children and pets. Avoid cardboard boxes and areas prone to leakage, such as under sinks. By following these storage guidelines, you can extend the lifespan of your candles and maintain their quality.
