Roman candles are a traditional type of firework that ejects exploding shells and coloured stars. The origin of their name is often attributed to the Roman Emperor Nero, who punished Christians by tying them to wooden stakes and using them as human candles to light parties. However, the fireworks themselves originated in China and have no link to ancient Rome other than their name. Roman candles were first mentioned in a 1769 publication, which also referenced Chinese Fire. So, what year were they invented?

What You'll Learn
Roman candles were a torture method
The term "Roman candle" today typically refers to a type of firework that ejects stars or exploding shells. These fireworks originated in China and have no direct link to ancient Rome beyond their name. The earliest recorded mention of Roman candles in the context of fireworks dates back to 1769, with subsequent references appearing throughout the 1800s.
It is important to distinguish between the modern fireworks and the ancient torture method, as they are connected only by name. The fireworks known as Roman candles are constructed with bentonite, lifting charge, pyrotechnic stars, black powder, and delay charge. They are ignited from the top and pointed upwards, away from people, to create a display of colored sparks and stars.
The Roman candle torture method, on the other hand, exemplifies the cruel and ruthless nature of Emperor Nero's regime. It serves as a reminder of the persecution faced by Christians during that time and the creative and horrific lengths to which the Romans went to inflict pain and suffering on those they deemed enemies of the state.
While the fireworks bring to mind childhood memories and joyful celebrations, the original Roman candles were a symbol of oppression and the brutal power wielded by the Roman Emperor. The stark contrast between the modern association of joy and the historical reality of torture underscores the complex and multifaceted nature of human history, where even the simplest of things can have a dark past.

Firework origin and naming
Fire, as we know, has fascinated and helped humanity since the beginning of our existence. The discovery of fire helped early humans cook food, stay warm, and scare away predators. Over time, we have also used fire for celebratory purposes, and fireworks are a testament to that. Fireworks are a class of low explosive pyrotechnic devices used for aesthetic, cultural, and religious purposes. Fireworks take various forms to produce four primary effects: noise, light, smoke, and floating materials (confetti, for example). Fireworks were first invented in China during the 7th century to scare away evil spirits, and they have been used ever since for various purposes and meanings.
Roman candles are a type of traditional firework that ejects one or more stars or exploding shells. They are constructed with bentonite, a lifting charge, a pyrotechnic star, black powder, and a delay charge. The firework is ignited from the top, pointed towards the sky and away from people. The delay powder is packed tightly in the tube, so the flame cannot reach the sides of the plug of the delay composition. Roman candles come in various sizes, from 6 mm (0.24 in) diameter for consumers to 8 cm (3.1 in) diameter in professional fireworks displays.
The name "Roman candle" is derived from a torture mechanism. Roman Emperor Nero is said to have punished devoted Christians by coating their strung bodies in pitch, oil, wax, and other flammable materials before lighting their feet and using them as human candles. The "Roman candles" were used to light formal parties within the imperial gardens, prolonging torture and pain. The term "Roman candle" now refers to a firework only linked to ancient Rome by name. The traditional firework originated in China.
The earliest use of candles is often attributed to the Ancient Egyptians, who made rushlights or torches by soaking the pithy core of reeds in melted animal fat. However, the rushlights had no wick like a true candle. While the Egyptians were using wicked candles in 3,000 B.C., the ancient Romans are generally credited with developing wicked candles before that time by dipping rolled papyrus repeatedly in melted tallow or beeswax. The resulting candles were used to light their homes, aid travellers at night, and in religious ceremonies. Historians have found evidence that many other early civilizations developed wicked candles using waxes made from available plants and insects.

Construction and composition
Roman candles are a traditional type of firework that ejects one or more stars or exploding shells. They come in a variety of sizes, ranging from 6 mm (0.24 in) in diameter for consumers to 8 cm (3.1 in) in diameter for professional displays. Roman candles are constructed with several components, including bentonite, lifting charge, pyrotechnic stars, black powder, and delay charge. The delay powder is packed tightly in the tube to prevent the flame from reaching the sides of the delay composition plug.
The construction of Roman candles involves arranging these components in layers within a cylindrical casing. The specific arrangement can vary, but a typical structure involves alternating layers of corn powder, stars, and a composition of other materials. This arrangement ensures that the Roman candle produces a consistent and controlled discharge of sparks, stars, or other effects.
The pyrotechnic stars in Roman candles are a crucial component that creates the colourful and sparkling effects. These stars are typically made from compounds that release visible light and other radiation when ignited. For example, potassium perchlorate (KClO4) can be used as an oxidizer, and through chemical reactions involving potassium and chlorine ions, barium compounds are formed, emitting green light.
Larger Roman candles, those with a diameter of three inches or more, employ a technique called "adding more lift." This involves increasing the lift charge in the higher layers and reducing it in the lower layers. This adjustment ensures that the stars or shells reach the same altitude, compensating for the shorter tube length available for acceleration in the higher layers.
Some very large Roman candles use comet shells instead of stars. The size and arrangement of these shells can vary, creating different visual effects. The use of comet shells adds to the variety and complexity of the display, making it a popular choice for professional fireworks displays.

Bans and legality
The term "Roman candle" refers to a traditional type of firework that ejects one or more stars or exploding shells. They are constructed with bentonite, lifting charge, pyrotechnic star, black powder, and delay charge. The firework is ignited from the top, pointed into the sky, and away from people.
Roman candles are banned in some countries due to their tendency to malfunction. Finland and the Netherlands have banned the firework, and it is illegal to possess or set off in several U.S. states, including California, Delaware, Florida, Maryland, Massachusetts, Minnesota, New Jersey, New York, North Carolina, Oregon, and Rhode Island.
In the United States, firework laws can be confusing, with varying regulations across states. Only one state, Massachusetts, completely bans the purchase and use of all consumer fireworks, including Roman candles. This ban dates back to 1943 during World War II.
It is important to note that even where Roman candles are legal, they can be dangerous and require caution. Fireworks are explosives and can cause fires and physical injuries. The American Pyrotechnics Association emphasizes the importance of safety measures, such as having a sober adult in charge, following instructions, and maintaining a safe distance for spectators.
The name "Roman candle" originates from a gruesome torture method employed by Roman Emperor Nero, where devoted Christians were coated in flammable substances, lit on fire, and used as human candles to light formal parties. The fireworks themselves, however, are believed to have originated in China.

Ancient Roman lighting
The term 'Roman candle' is used to refer to a traditional type of firework that ejects exploding shells. However, the name originates from a gruesome form of torture and execution employed by the Romans, in which devoted Christians were coated in flammable materials and lit up as human candles. The Roman Emperor Nero is said to have used these 'Roman candles' to light up parties within the imperial gardens.
In terms of lighting, the ancient Romans primarily used oil lamps, as olive oil was cheap and readily available. These oil lamps served utilitarian, ritualistic, and symbolic purposes. They were used to light streets, paths, military encampments, boats, and venues for entertainment such as gladiator shows and theatrical performances. In religious contexts, oil lamps were used to light temples and shrines, and they were also a common component in burial practices. Lamps were often buried with the dead to light their way in the afterlife.
Oil lamps could be made of clay or metal, usually a copper alloy. They featured a wick, a reservoir for fuel, and an air supply to maintain a flame. Some lamps had multiple nozzles, which burned more fuel and were considered a status symbol. These lamps were often displayed by wealthy families and featured intricate designs. The firmalampen or factory lamp style, developed in the 1st century CE, featured a channel running down the nozzle to divert spilled oil back into the lamp.
While the Romans did have candles, they were considered luxury items and status symbols, often given as gifts. The Romans were likely the first to create a recognisable candle around 500 BC, made from tallow or rendered animal fat. However, due to the unpleasant aroma of tallow candles, they were not widely used until the supply of oil decreased following the fall of the Roman Empire.
