What You'll Learn
Modern candles are often made from paraffin wax
The candle-making process has evolved over time, with improvements in production techniques and a focus on creating more environmentally friendly and healthier products. While paraffin wax candles are still prevalent, consumers are increasingly opting for candles made from natural waxes, such as soy.
Soy candles were invented over twenty years ago and are known for their long-burning times, minimal soot production, and ability to hold fragrances effectively. Soy wax is a renewable resource, supporting local farmers and the local economy. It is also free from pesticides and herbicides, and toxic chemicals, making it a safer and more environmentally friendly alternative to paraffin wax.
The shift towards soy candles is driven by consumers seeking sustainable and non-toxic options. While paraffin wax candles may be more cost-effective, soy candles offer a healthier and more eco-conscious choice. Additionally, the natural fragrance of soy candles provides an uplifting aromatherapy experience, enhancing their popularity among consumers.
In conclusion, while modern candles are often made from paraffin wax due to its affordability and accessibility, there is a growing trend towards soy wax candles. The increasing consumer awareness of health and environmental impacts has led to a preference for natural waxes, driving the demand for soy candles in the market. As a result, candle manufacturers are responding to these changing preferences by offering a wider range of environmentally friendly and health-conscious options.

Cotton is the most common candle wick material
Candles are made up of a wick embedded in wax or another flammable solid substance such as tallow. Over the years, candles have been made from various waxes, fats, and oils, many of which are derived from animals, insects, and plant matter.
Candle wicks are almost always made out of cotton, which has been tightly braided to make it safe to burn and self-combusting. This provides a clean and environmentally friendly burn. The wick's capillarity determines the rate at which the melted hydrocarbon is conveyed to the flame. If the capillarity is too great, the molten wax streams down the side of the candle. Wicks are often infused with chemicals to modify their burning characteristics. For example, it is usually desirable that the wick not glow after the flame is extinguished, so chemicals such as ammonium nitrate and ammonium sulfate are used.
In modern candles, the wick is designed to curve over as it burns, ensuring that the end of the wick is incinerated by the fire, trimming itself. This is an improvement from pre-19th-century wicks, which required regular trimming with scissors or specialised wick trimmers to promote steady burning and prevent the release of black smoke.
While cotton is the most common wick material, some candles now use wooden wicks, which provide a gentle and safe flickering effect as the wax melts. The choice between cotton and wooden wicks depends on personal preference.

Soy candles are a natural, environmentally-friendly alternative
Candles are an ignitable wick embedded in wax or another flammable solid substance, and they have been used for over two millennia. Early candles were made of beeswax, but these were expensive and inaccessible to most people. Cheaper alternatives like tallow (animal fat) were used, but these produced a strong smell. In modern times, candles are made from a variety of materials, with paraffin wax being the most common due to its affordability.
However, paraffin wax is a byproduct of the petrochemical industry, and consumers are increasingly turning away from candles made with harsher ingredients. This has led to the rise of soy candles as a natural, environmentally-friendly alternative. Soy wax candles are made from soybeans, which are a renewable agricultural product. The oil is extracted and hydrogenated to create a solid form suitable for candle-making. This process alters the oil's melting point, allowing it to solidify at room temperature.
Soy candles are biodegradable, reducing landfill waste, and have a lower carbon footprint than paraffin wax. They support local agriculture and economies by creating demand for soybeans. Additionally, soy candles are smoke-free, burn evenly, and can be infused with natural fragrance oils to provide an uplifting aromatherapy experience.
However, it is important to note that the environmental impact of soy wax is nuanced. The expansion of soy cultivation has been linked to deforestation, and the use of pesticides and herbicides in soybean farming is a concern. Additionally, soy candles may produce small amounts of harmful substances if not adequately manufactured or if they contain certain additives. To ensure the most environmentally-friendly option, consumers should choose soy wax candles with certifications like the Rainforest Alliance.
In conclusion, soy candles offer a natural and eco-friendly alternative to traditional paraffin wax candles. While there are some considerations regarding soybean farming practices and additives, soy candles still present a renewable and biodegradable option that contributes to a lower carbon footprint.

Ancient candles were made from animal fats
Modern candles are typically made from paraffin wax, beeswax, or soy wax, each offering different properties and benefits. Paraffin wax, derived from petroleum, is the most common and affordable option, while beeswax, produced by bees, provides a longer burn time and a natural, sweet scent. Soy wax, extracted from soybeans, is a popular, eco-friendly choice known for its clean burning and longevity. However, before these varieties of wax were used, ancient candles were often made from animal fats, also known as tallow.
Animal fats were once a primary source of fuel for lighting and played a significant role in ancient candle-making. The process typically involved rendering the fat from various animals, including cows, sheep, and goats, by heating and melting it to remove impurities. The purified fat was then poured into containers, often made of clay, stone, or metal, and allowed to harden, forming a candle. Wicks were also important, and early candle-makers used fibrous materials like reeds, twisted cloth, or even plaited Rushes, ensuring the candle could burn efficiently.
The use of animal fats for candles was prevalent in ancient civilizations, including the Egyptians, Romans, and Greeks. These candles were an essential source of light and were often used in religious ceremonies and to illuminate homes and public spaces. Animal-based candles were also common during the Middle Ages, where they were valued for their practicality and affordability. However, the quality varied, and candles made from animal fats often produced a smoky flame and an unpleasant odor, particularly if the fat was not properly purified.
The process of making candles from animal fats could be labor-intensive and time-consuming. In some cases, candle makers would need to boil the fat multiple times to ensure it was clean and free of impurities. The fat would then be strained and sometimes scented with essential oils or herbs to mask any remaining unpleasant odors. The type of animal fat used also made a difference in the candle's quality, with fats from different animals producing varying results in terms of burn time, scent, and smoke production.
While animal-based candles have largely been replaced by more modern wax options, the practice of using animal fats for lighting and religious purposes still exists in some traditional communities. Additionally, the knowledge and techniques of ancient candle-making using animal fats continue to be of interest to those studying historical crafts and ancient technologies, providing a fascinating insight into how our ancestors illuminated their world. Today, candle-making has evolved, and the use of animal fats is mostly limited to specific cultural or traditional practices, with most candle makers and consumers favoring the more accessible and aesthetically pleasing modern wax alternatives.

Modern candle wicks self-trim as they burn
Candles have been used for over two millennia, and while they are no longer necessary for illumination, they are still used for functional, symbolic, and aesthetic purposes. Over the years, candles have been made from various waxes, fats, and oils, many of which were derived from animals, insects, and plant matter. For example, ancient Egyptians made candles by dipping reeds in melted animal fat, while ancient Romans used papyrus.
In modern times, candles are typically made from paraffin wax, which, along with efficient production techniques, has made candles affordable for the masses. However, consumers are increasingly turning away from paraffin wax due to its association with the petrochemical industry and its potential negative impact on health and the environment. As a result, there has been a growing preference for candles made from more natural ingredients, such as beeswax and soy wax.
Soy candles, in particular, have gained popularity for their environmental friendliness and health benefits. Soy wax is a natural product derived from soybeans, which are grown locally in the United States. It produces less soot than paraffin wax and holds fragrance better. Soy candles are also known for their long burning times, beautiful light, and rich scent. Additionally, soy candles are free from toxic chemicals and carcinogens that may be present in paraffin candles, making them a safer option for consumers.
One of the key components of a candle is its wick, which holds the flame. Modern candle wicks are designed to self-trim as they burn, eliminating the need for regular trimming with scissors or specialised wick trimmers. This self-trimming feature is achieved by constructing the wick in a way that causes it to curve over as it burns, ensuring that the end of the wick is incinerated by the flame. Commercial wicks are typically made from braided cotton, which provides a clean and environmentally friendly burn.
The braiding technique used in wick construction not only ensures stability but also influences the rate at which the melted wax is conveyed to the flame. Wicks can be infused with chemicals to modify their burning characteristics, such as preventing the wick from glowing after the flame is extinguished. Overall, the design of modern candle wicks, including their self-trimming capability, contributes to a more efficient and enjoyable candle-burning experience.
