Candles are solid blocks of wax with an embedded wick that can be ignited to provide light, heat, or fragrance. They are made from various substances, including beeswax, microcrystalline wax, plant waxes, tallow, and gel. Candle wax, in particular, is a mixture of hydrocarbons, predominantly alkanes, which are compounds composed solely of carbon and hydrogen atoms. The type of wax and wick used can affect the burn rate and quality of the candle. Candles have been used for over two millennia, initially as a significant form of indoor lighting and later for decorative, symbolic, and ceremonial purposes in various cultural and religious contexts.
| Characteristics | Values |
|---|---|
| Composition | Candle wax is a mixture of hydrocarbons, predominantly alkanes, composed solely of carbon and hydrogen atoms. |
| Hydrocarbons | Hydrocarbons are classified into different groups based on their structure and bonding, including alkenes, and alkynes. |
| Alkanes | Alkanes are the simplest family of hydrocarbons with single bonds and maximum hydrogen capacity, making them stable, non-reactive, and suitable for combustion. |
| General Formula for Alkanes | The general formula for alkanes is CnH(2n+2), where 'n' represents the number of carbon atoms in the molecule. |
| Candle Ingredients | Candles are made from various ingredients, including microcrystalline wax, beeswax, gel (a mixture of polymer and mineral oil), plant waxes (palm, carnauba, bayberry, soybean wax), and tallow. |
| Wicks | Coreless wicks have no core material. Traditional wicks required trimming, while modern wicks curve over and self-trim through incineration. |
| Production Methods | Traditional methods involve melting solid fuel with controlled heat and pouring it into a mould or dipping a wick. Modern methods use extrusion moulding. |
| Additives | Additives like vybar, stearic acid, or UV inhibitor are blended with wax to enhance burning qualities or alter properties. |
| Curing Time | Curing time is the period between pouring the candle and it reaching an optimum state to be lit, enhancing fragrance. |
| Viscosity | Viscosity refers to a fluid's resistance to flow; candles with higher viscosity additives may burn slower. |

Candle wax is a mixture of hydrocarbons, predominantly alkanes
A candle is an ignitable wick embedded in wax or another flammable solid substance, such as tallow, that provides light and, in some cases, a fragrance. Candles have been used for over two millennia worldwide and were a significant form of indoor lighting until the invention of other light sources.
The kind of wax used in a candle affects its burn rate. For example, beeswax and coconut wax burn longer than paraffin or soy wax. Candles can be made from various types of wax, including microcrystalline wax, beeswax, gel (a mixture of polymer and mineral oil), plant waxes (such as palm, carnauba, bayberry, or soybean wax), and paraffin wax.
In addition to wax, candles may also contain additives to enhance their burning qualities or alter their properties. These additives may include vybar, stearic acid, or a UV inhibitor. Essential oils or fragrance oils are often added to candles to provide a pleasant aroma. The curing time of a candle, or the time between pouring and lighting, is important for enhancing the fragrance and allowing the candle to set and age.

Candles are made from plant waxes, like palm, carnauba, bayberry, or soybean wax
Candles are solid blocks of wax with an embedded wick that can be ignited to provide light, heat, or fragrance. They are made from a variety of waxes, including plant waxes such as palm, carnauba, bayberry, and soybean wax.
Palm wax is a natural wax derived from hydrogenated palm oils. It is a vegan wax, but its production has an environmental downside, as it requires the extraction of oil from palm trees. Palm wax is not ideal for candle production and is not generally recommended by the candle-making community.
Soy wax, derived from soybeans, is a popular choice for candles due to its eco-friendly, sustainable, and biodegradable nature. It is also vegan and offers a slow, steady burn, making it great value for money. Soy wax burns cleaner than most waxes and holds fragrances well, allowing for a long-lasting aroma. However, there are some concerns about the soybean industry's use of deforestation, fertilizers, and pesticides. Additionally, soy wax may not be suitable for those who prefer a lighter scent, as it doesn't hold fragrance as well as some other waxes.
Carnauba wax is another plant-based wax that can be used for candles. While it is a hard wax with a high melting point, making it suitable for certain applications, its high price and limited availability make it less commonly used in candle-making.
Bayberry wax is a type of plant wax that has been used traditionally to make candles. It has a natural green colour and a pleasant scent, making it ideal for creating unique, fragrant candles. However, bayberry wax is less commonly used today due to the time-consuming process of rendering the wax from the bayberry shrub and the limited availability of the raw material.
Plant waxes offer an alternative to traditional candle waxes like paraffin, beeswax, and tallow. These plant-based waxes provide options for vegan, eco-friendly, and sustainable candles, contributing to a growing market that values natural and renewable sources.

Beeswax candles were historically used in churches and by the elite
Beeswax candles have been used for centuries, dating back to ancient Rome, and were the only type of candle used in the Catholic Church for ceremonial purposes. The use of beeswax candles was not limited to the church, as they were also burned in the households of the wealthy as a luxury item.
Beeswax candles are made from the byproduct of honey collection, and their use in churches is steeped in tradition and symbolism. Beeswax is consumed by the flame without dripping, and it burns evenly and slowly, making the candle last a long time. The slow burn of beeswax candles is one reason why they were favoured by the church and the elite.
In the history of religion, light and fire have often accompanied sacred rites. The fire of the altar and the lights of the sacrificial chamber have been used symbolically and have even assumed the halo of divinity. Beeswax, in particular, was valued by the Roman Catholics because it comes from virgin bees, symbolising how the Light of the World, Christ, was cloaked in virginity at birth.
The percentage of beeswax in church candles was historically regulated by church law. The Pascal candle, the two candles for low Mass, six for High Mass, and the twelve necessary for Benediction were required to have at least 65% beeswax. All other candles used on the altar had to contain at least 25% beeswax. While these regulations have since changed, the church still places a high value on candles, and they remain a key part of liturgical ceremonies.

Tallow was a cheaper alternative to beeswax, but less aesthetically pleasing
Candles are solid blocks of wax with an embedded wick that can be ignited to provide light, heat, fragrance, or to keep time. They have been used for over two millennia, and while they are no longer essential for illumination since the invention of electric light, they are still used for functional, symbolic, and aesthetic purposes.
Candles can be made from a variety of substances, including microcrystalline wax, beeswax, gel, plant waxes, and tallow. Beeswax candles were historically expensive and their use was limited to the elite and churches. Tallow, on the other hand, was a cheaper alternative, but it was less aesthetically pleasing. Tallow is a rendered form of fat, typically from cattle or sheep, and has been used for centuries in the Far East as well as during the Middle Ages in Northern Europe, especially England.
The use of tallow as a candle-making material is mentioned in English records dating back to 1154. However, its less aesthetically pleasing appearance likely contributed to its exclusion from use in altar candles, as decreed by papal bulls.
Beeswax, a byproduct of honey collection, has a higher burning rate compared to other waxes like paraffin or soy wax. It also has protective, humectant, and antibacterial properties, making it a valuable substance beyond its use in candles.
While tallow may not have been as visually appealing as beeswax, it has found modern applications in skincare products, such as balms, soaps, beard butter, and eye and lip creams. Tallow-based skincare brands prioritize the use of natural and organic ingredients, often sourcing their tallow from regenerative and sustainable farms that prioritize animal welfare and environmental stewardship.

Modern candles use additives to enhance burning qualities and fragrance
Candles have been used for over two millennia, and while they are no longer necessary for illumination, they are still commonly used for functional, symbolic, and aesthetic purposes. Modern candles are made from a variety of materials, including paraffin wax, beeswax, coconut wax, soy wax, and plant waxes.
Candle manufacturers can select from a wide range of additives to enhance the burning qualities and fragrance of their products. For example, Vybar is an additive that increases scent throw and reduces wax shrinkage. The type of wax used also affects the burn rate, with beeswax and coconut wax burning longer than paraffin or soy wax.
The addition of fragrance to a candle should be carefully monitored to ensure that the candle will burn cleanly and properly. Fragrance materials may be derived from natural sources, such as essential oils, or from synthetic aroma chemicals. These synthetic chemicals are also found in many perfumes, bath soaps, lotions, and shampoos, and are safe, high-quality ingredients. Various health and safety tests are conducted on the raw fragrance materials used in candles to ensure their safety for consumers.
When choosing a scented candle, it is important to select one that uses natural waxes, high-quality fragrance oils, and natural or no colorants. Natural colorants include plant extracts such as beet juice and turmeric, while synthetic colorants are created in a lab and can be harmful to the environment. The wick of a scented candle should also be of high quality and made from natural materials such as cotton, wood, or hemp. Synthetic wicks can release harmful chemicals when burned, negatively impacting air quality.
