Candles have been used for over two millennia, and while they are no longer a primary source of light, they remain popular for functional, symbolic, and aesthetic purposes. The global candle market was valued at USD $6.8 billion in 2021 and is expected to surpass USD $9.9 billion by 2028. The COVID-19 pandemic and the ensuing lockdowns led to a dramatic increase in the sales of scented candles. In this response, I will outline the process of how commercial candles are made.

Candle wax types: paraffin, soy, beeswax, microcrystalline, gel, plant, etc
Commercial candles are made by heating wax into a clear, near-liquid state, filtering it to remove impurities, adding dyes and perfumes, and then pouring the wax into a mould with a wick. The type of wax used varies, and different types of wax have different properties.
Paraffin wax is the most common type of candle wax. It is inexpensive, holds fragrance and colour well, and is available in various melt points. However, it is not very eco-friendly, as it is derived from the oil industry. Paraffin wax was first distilled from coal and oil shales by James Young in the mid-1850s, leading to the mass production of inexpensive, high-quality candles.
Soy wax is a natural, plant-based wax made from soybean oil. It is renewable, easy to handle, and offers a slow, steady burn. It is more eco-friendly than paraffin wax, but there are some concerns about the soybean industry's use of deforestation, fertilisers, and pesticides. It also doesn't hold fragrance as well as paraffin wax.
Beeswax is another natural option, produced by bees during the honey-making process. It has a subtly sweet scent and is quite solid, making it ideal for crafting free-standing pillar candles. However, it is more expensive than other types of wax.
Other types of wax used for candles include microcrystalline wax, gel wax (a mixture of polymer and mineral oil), coconut wax, and plant waxes such as palm, carnauba, and bayberry wax.

Candle wicks: cotton, linen, or other materials, often braided
Candle wicks are made from a variety of materials, including cotton, linen, and other materials, often braided. The wick's capillarity, or ability to convey melted wax to the flame, is determined by its material and construction. Braided cotton wicks, for example, are commonly used in commercial candles and are designed to curl over as they burn, maintaining the height of the wick and, consequently, the flame. This self-trimming or self-consuming property of braided wicks prevents excess wick from falling into the melted wax.
Cotton wicks are also used in the traditional dipping method, where the wick is repeatedly dipped into molten wax until the desired thickness is achieved. Beeswax candles, for instance, were historically made using both the dipping method and the pouring method. In the pouring method, the melted wax is poured over a suspended cotton wick, which is simultaneously twirled manually.
Linen wicks are another option for candle wicks. Like cotton wicks, linen wicks are often braided and treated with chemicals or inorganic salt solutions to ensure proper burning. This treatment causes the linen wick to bend at a 90-degree angle when burning, allowing the end of the wick to remain in the outer mantle of the flame and burn at a controlled rate.
Historically, candle wicks were made from a variety of natural materials, including plant fibres such as oakum, dried rushes, and rice paper, as well as animal-based products like tallow (made from beef or mutton fat) and whale fat. These materials were commonly used in ancient China, Japan, India, and Europe, with evidence of their use dating back to the Qin dynasty (221–206 BCE) in China and the Etruscan period in Italy.
In modern times, candle wicks have evolved to include synthetic materials and blends, reflecting the advancements in candle-making technology and the shift towards more sustainable and environmentally friendly options. Soy wax, for instance, has gained popularity due to its natural production process, affordability, clean burn, and ability to hold scents effectively.

Candle-making methods: dipping, pouring, moulding, extrusion, etc
Candle-making methods have evolved over the centuries, from hand-crafted creations to modern mechanised processes. The earliest candles were made by dipping wicks into molten wax, and this method is still used today by craftspeople making artisan candles. The dipping method involves repeatedly dipping a wick into molten wax until the wax builds up to the desired thickness. Beeswax candles, for example, were historically made using both the dipping method and pouring method.
In the pouring method, melted wax is poured over a suspended wick, which is simultaneously twirled. This method is used to create tapered candles. The pouring method is also used in modern candle-making machines, where the wax is poured into a mould. The moulds are often made of tin and are pre-heated so that the wax flows evenly into them. The pouring speed and wax temperature can be adjusted, and some machines can pour multiple moulds at once. This method is commonly used to create candles with irregular shapes, but it is not practical for large-scale production.
Another method of candle-making is moulding, which was introduced in the 19th century as a large-scale industrial manufacturing technique. In this process, a wick is pulled through the tip of the mould, and the wax is then poured into the mould. Continuous moulding machines can produce groups of 50 to 500 candles in almost 30 minutes.
Extrusion is a modern production method where wax is forced through a die to create a specific shape. Unlike moulding, extrusion forms one continuous length of candle that must be cut into the proper sizes. Candle extruders are often used in large-scale factories as they can produce candles quickly and uniformly. They also allow for the efficient incorporation of fragrant oils and additives, resulting in a consistent product.

Candle scents: pumpkin, vanilla, honey, bayberry, etc
Commercial candles are typically made using continuous moulding machines, which can produce anywhere from 50 to 500 candles per load. The process involves pulling the wick through the tip of the mould, melting the wax to slightly above its melting point, and then pouring it into a mould located above the wick. The moulds are pre-heated to ensure the wax flows evenly. Before the wax is poured, it is heated to a clear, near-liquid state and filtered to remove impurities. This is when any dyes or perfumes are added to the wax.
Candle manufacturers can create different scents by using fragrance oils or essential oils.
Pumpkin Spice
To make a pumpkin spice candle, you can add vanilla, pumpkin seasoning, and nutmeg to your wax. The colour of the wax will darken, but you can adjust this by adding an orange crayon.
Vanilla
Vanilla fragrance oil can be added to the wax to create a sweet-smelling candle. Essential oils can be used, but vanilla can be difficult to replicate naturally, so fragrance oils are recommended.
Honey
Honey vanilla candles can be made by melting beeswax in a metal pitcher and then allowing it to cool before adding honey and vanilla fragrance oil. Essential oils can also be added to honey vanilla candles, with floral oils like lavender, chamomile, and jasmine pairing well.
Bayberry
Bayberry wax is derived from the fruit of the bayberry bush and has been used to make candles for centuries. To make bayberry candles, you can either purchase pre-made bayberry wax or extract the natural wax from bayberries by boiling them in water and then filtering the mixture through cheesecloth. The wax then needs to be melted and combined with beeswax to make taper candles.
Other Scents
Other popular candle scents include floral fragrances like lavender and jasmine, as well as woodsy scents like Siberian fir, sandalwood, and cedarwood.

Candle history: from whale fat to modern soy wax
Candles have been used as a source of light for over 5,000 years, and their history is long and storied. The earliest candles were made by ancient civilizations like the Egyptians, Romans, and Greeks, who used them for light, ceremonies, and celebrations. These early candles were made from plant materials dipped in animal fat, with wicks made from dried rushes.
In the Middle Ages, beeswax candles were introduced in Europe, offering a purer, cleaner-burning alternative to animal-based tallow. Beeswax candles were more expensive and were mostly used by the wealthy and churches. The Chinese also used beeswax during the Tang and Sung dynasties, along with wax from the Chinese tallow tree and insects. In India, candle wax was made by boiling the fruit of the cinnamon tree.
During the 18th and 19th centuries, the growth of the whaling industry led to the use of spermaceti, a wax derived from sperm whale oil, in candlemaking. Spermaceti candles burned brighter and produced less odour than tallow candles. Around the same time, stearin wax was developed by French chemist Michel Eugene Chevreul, who discovered how to extract stearic acid from animal fatty acids.
In the mid-19th century, James Young developed a method for distilling paraffin wax from coal and oil shales, making it possible to produce inexpensive, high-quality candles. By the end of the 19th century, candles were primarily made from paraffin wax and stearic acid, with companies like Price's Candles in London mass-producing candles using industrial manufacturing techniques.
In the 20th century, the increased availability of byproducts from the oil and meatpacking industries further drove down the cost of candle production, making candles accessible to the masses. Candles also began to be valued for their decorative and aesthetic qualities, with scented candles gaining popularity in the 1980s and 1990s. During this time, new types of candle waxes were developed, including soybean wax, a softer and slower-burning alternative to paraffin.
Today, candles are made from a variety of materials, including paraffin wax, beeswax, soy wax, palm wax, and plant waxes, and continue to be valued for their functional, symbolic, and decorative purposes.
