Candles have been used for over 5,000 years, with the earliest use attributed to the Ancient Egyptians. In the Roman period, candles were made from tallow and beeswax, with the latter being too expensive for anyone other than the wealthy to burn in their homes. In the 18th and 19th centuries, candles were made from spermaceti, a wax obtained from sperm whales. This wax burned cleanly and was odourless. Today, candles are no longer used as a major source of light, but they are popular for their fragrance. However, candles do expire and can lose their scent over time.

What You'll Learn
Candles lose their scent over time
The use of candles dates back to ancient times, with the Ancient Egyptians using wicked candles in 3000 B.C. and the Romans developing wicked candles before that. Candles have been used as a source of light, in religious ceremonies, and to illuminate celebrations.
Today, candles are still popular, often filling a room with a warm, flickering light and a pleasant fragrance. However, candles can and often do lose their scent over time. This is due to the breakdown of fragrance oils, which causes a decrease in scent intensity. While candles do not spoil like food or drinks, they do expire and can become weak, outdated, and odourless.
The lifespan of a candle depends on several factors, including the type of wax, the size of the candle, and the concentration of fragrance oils. Soy wax, for example, is known for its clean, slow burn and gradual fragrance release, while paraffin wax has a stronger initial scent throw but may not last as long. Beeswax is naturally aromatic but may be less potent for strong fragrances. Additionally, high-quality fragrance oils will maintain their strength for longer, while cheaper oils may evaporate or lose potency more quickly.
Proper candle care and storage are crucial to preserving the life of your candles. Exposure to air, heat, and light can cause fragrance oils to degrade, so storing candles correctly can help extend their scent life. Most candles retain their fragrance well for around one to two years if stored properly.
There are also ways to maximise the life of your candles while burning them. For example, trimming the wick before each use helps control the flame size, reduce soot, and ensure an even burn, preserving the candle's scent and preventing wax tunneling. Burning candles for two to four hours at a time allows the wax to melt evenly, improving scent throw and preventing tunneling.

The ideal burn time for candles is 3-4 hours
Candles have been used as a source of light and in religious ceremonies for over 5,000 years. The Ancient Egyptians made wicked candles as early as 3,000 B.C., and the ancient Romans created candles by dipping rolled papyrus in melted tallow or beeswax. While candles are no longer a primary source of light, they remain popular for ambiance, fragrance, and practical purposes.
To calculate the total burn time of a candle, you can use the formula: Total Burn Time = Original Weight / Hourly Burn Rate. The original weight is the total weight of the candle before it is lit, and the hourly burn rate is calculated by lighting the candle for a single burn cycle of 4 hours, allowing it to cool, and then measuring the weight difference. This number is then divided by 4 to get the hourly burn rate.
It is important to note that the burn time of a candle can be influenced by various factors such as the size of the candle, the type of wax, the wick size, and the burning environment. Larger candles with more wax generally have longer burn times, and wider candles require larger wicks. Natural waxes like soy and coconut are known for offering clean and luxurious burning experiences. Additionally, proper candle care, such as regular wick trimming and avoiding drafts, can help extend the life of a candle.
While candles do not spoil like food or drinks, they can expire and lose their scent over time. Discoloration, wick performance issues, and a weak cold throw (fragrance of an unlit candle) are indicators of an expired candle. However, burning an expired candle is typically safe as long as instructions are followed, although it may not provide the same fragrance experience or burn as evenly.

Ancient Egyptians made the first wicked candles
The use of candles dates back to ancient times, with the earliest recorded use attributed to the Ancient Egyptians. While the Ancient Egyptians created rushlights or torches by soaking the pithy core of reeds in melted animal fat, these lacked a wick and were thus not true candles. However, they are believed to have made the first wicked candles around 3,000 B.C.
The Ancient Egyptians played a significant role in the early development of candles, using materials available to them at the time. They created rushlights, which were a type of candle-like structure, by soaking the dried pith or core of the rush plant in melted animal fat or grease. This process resulted in a cheap and long-lasting source of light that was accessible even to the poor.
While the Ancient Egyptians are credited with creating the first wicked candles, it is important to mention that these candles did not resemble the modern candles we use today. The Egyptians' candles were made by dipping rolled papyrus repeatedly in melted tallow (animal fat) or beeswax. This innovation marked a significant advancement in candle-making, as the resulting candles produced a brighter and cleaner light compared to the smoky flame and foul odour of traditional tallow candles.
The invention of wicked candles by the Ancient Egyptians had a lasting impact on candle-making and usage. Their candles were used not only for lighting their homes but also for aiding travellers at night and in religious ceremonies. The development of wicked candles by the Egyptians inspired other early civilizations to create their own versions using locally sourced materials. For example, the Chinese used rolled rice paper as wicks, while tribes in Alaska and Canada utilized the oily eulachon fish, which could be lit and burned like a candle.
The evolution of candle-making continued with the introduction of beeswax candles in the Middle Ages. These candles, made from beeswax, burned cleanly without producing smoke and emitted a pleasant sweet smell. However, due to their expense, only the wealthy could afford to use them in their homes. The growth of the whaling industry in the late 18th century brought another significant change to candle-making with the availability of spermaceti wax, which burned brighter and cleaner than tallow or beeswax.

Candles were made from animal fat and beeswax in Europe
The use of candles dates back to ancient times, with the Ancient Egyptians making torches by soaking the pithy core of reeds in melted animal fat. The Romans are generally credited with developing wicked candles by dipping rolled papyrus in tallow or beeswax. These candles were used for lighting homes, aiding travellers, and religious ceremonies.
In Europe, candles were primarily made from animal fat (tallow) and beeswax from the Roman period until the modern era. Tallow, derived from the fat of cows or sheep, was the standard material for candles in Europe. However, the unpleasant smell of tallow candles due to their glycerine content led to their manufacturing process being banned in several European cities.
Beeswax, a byproduct of honey collection, was introduced as an alternative to tallow in the Middle Ages. Beeswax candles offered several advantages over tallow, burning cleanly and emitting a pleasant sweet smell. They were widely used in church ceremonies and by the wealthy, as they were more expensive.
The growth of the whaling industry in the 18th century brought another significant change to candlemaking with the introduction of spermaceti, a wax derived from sperm whale oil. Spermaceti candles, like beeswax candles, burned without producing a repugnant odour and offered improved hardness and brightness.
Over time, candle-making techniques evolved, and in the 19th century, stearin wax was developed from animal fatty acids, providing a hard and durable option that burned cleanly. Today, stearin candles remain popular in Europe, and candle-making continues to innovate with new types of waxes being developed to meet diverse preferences and needs.

Scented candles can be preserved
Candles have been used as a source of light and in religious ceremonies for over 5,000 years. The Ancient Egyptians made torches by soaking the pithy core of reeds in melted animal fat. The Romans are credited with developing the wicked candle before this time by dipping rolled papyrus in melted tallow or beeswax. The first "standard candles" were made from spermaceti wax, obtained by crystallizing sperm whale oil, in the late 18th century. Beeswax candles were also widely used for church ceremonies, but only the wealthy could afford to burn them at home.
Beeswax candles were a major improvement on animal-based tallow, burning cleanly and emitting a sweet smell rather than a foul odour. Today, candles are no longer used as a major source of light, but their popularity continues to grow. Scented candles, in particular, have become increasingly popular. However, candles can and do lose their scent over time. This is due to the ingredients in the candle, such as the wax and fragrance, becoming less effective. Heat and sunlight can also cause discolouration, fading, and a change in the candle's scent.
So, how can scented candles be preserved? Firstly, it is recommended to use candles within a year and a half of purchasing them. This lifespan will vary depending on the size of the candle, the type of wax, and the fragrance oil used. For example, natural or organic waxes like soy and coconut are known for offering clean and luxurious burning experiences. Additionally, candles should be stored in a cool, dry place away from direct sunlight to prevent discolouration and fading.
Before lighting a candle, it is important to trim the wick to around one-fourth-inch high to ensure even burning and prevent bursts of high flames or smoking. It is also recommended to burn a candle for no more than 3 to 4 hours at a time to prevent the wax from overheating and becoming too thin. Allowing the candle to cool completely before lighting it again makes it safer to trim the wick and clean off any wax.
By following these simple steps, scented candles can be preserved and enjoyed for longer.
