Roman candles are fireworks that eject one or more stars or exploding shells. They are constructed with bentonite, a lifting charge, a pyrotechnic star, black powder, and a delay charge. Roman candles are said to be called so because of their association with the Roman Emperor Nero, who is known for having captured Christians to burn them in his garden at night for light entertainment. The act of lighting things on fire, or burning, is also linked to the origin of the name. While Roman candles have a history that dates back to ancient Rome, they were traditionally fireworks that originated in China.

Roman candle fireworks were named after a torture method
The term "Roman Candle" today refers to a firework that originated in China. It ejects exploding shells and launches stars into the sky through a process of ignition and delay powder. While the firework shares a name with the ancient torture method, its connection to ancient Rome is limited to its title. The dangerous nature of Roman candles has led to their ban in several countries, including Finland and the Netherlands, and their possession or use is illegal in multiple U.S. states due to safety concerns.
The Roman candle fireworks may have acquired their name from the gruesome execution method employed by Emperor Nero. The slow and painful nature of death by burning, starting from the feet upwards, resembles the functioning of the firework itself. This folk etymology, arising from the narrative of Christian persecution, adds a layer of exoticism and intrigue to the fireworks, potentially enhancing their appeal to some audiences.
While the exact timing is unclear, the naming of Roman candle fireworks after a torture method showcases a fascinating interplay between history and pyrotechnics. The association with Emperor Nero and his cruel entertainment for elite guests adds a layer of complexity to the origins of this firework variety. Despite their ancient Roman namesake, Roman candles, with their colourful displays of stars and sparks, have become a beloved feature of celebrations and childhood memories, divorced from their torturous past.

Roman candles are banned in some countries
The Roman candle, a traditional type of firework, has a long and intriguing history dating back to ancient times. While their exact origin is unknown, they are believed to have originated in China, where they were used as early as the 5th century. The name "Roman candle" is thought to derive from their widespread use in Roman times, where they were a popular feature of celebrations and festivities.
Over time, Roman candles have become synonymous with fireworks displays and are loved for their distinctive effects. They work by shooting multiple stars or sparks in rapid succession, creating a dazzling and colorful display. Despite their popularity, however, Roman candles have also been at the center of safety concerns and regulations.
The burning debris and sparks emitted by Roman candles can cause burns, eye injuries, and respiratory issues. They can also ignite nearby objects, leading to property damage and wildfires. The risk is especially high in dry conditions or areas with flammable materials nearby. As a result, many countries have implemented bans or strict regulations to protect public safety.
Another reason for the bans is the potential for misuse and illegal activities. Roman candles, when misused, can be dangerous projectiles. They have been associated with violent incidents and criminal activities, where they are used as makeshift explosive devices. To prevent such misuse and ensure public safety, some countries have opted to ban them entirely.
While the ban on Roman candles may disappoint fireworks enthusiasts, it is important to prioritize safety. There are still many other types of fireworks available that can be enjoyed safely and responsibly. It is crucial to follow local regulations and only purchase legal and professionally manufactured fireworks to minimize risks and ensure a enjoyable and accident-free experience for all.

The fireworks are constructed with bentonite, lifting charge, pyrotechnic stars, black powder and delay charge
Roman candles are a traditional type of firework that ejects one or more stars or exploding shells. They are constructed with bentonite, a lifting charge, pyrotechnic stars, black powder, and delay charge. The device is ignited from the top, which should be pointed upwards, away from people. The delay charge is packed tightly in the tube so that the flame cannot reach around the sides of the plug of delay composition. It burns slowly and, as it is consumed, the flame moves down the tube. When the flame reaches the topmost pyrotechnic star, the star is ignited. As the star fits loosely in the tube, the fire spreads around it and ignites the lift charge. The lift charge burns quickly, propelling the star out of the tube and igniting the layer of delay charge beneath it. This process repeats.
The stars inside fireworks are made of metal salts, which are powdered combinations of metal and other chemical components. When the stars ignite, the metal particles absorb a large amount of energy. Once they begin to cool, the particles emit this energy in the form of light. The colour of this light depends on the type of metal used. For example, strontium produces red light, calcium produces orange light, and barium produces green light.
The lift charge, located at the bottom of the shell, is made from black powder, a type of gunpowder invented in China over 1000 years ago. It is made from 75% potassium nitrate (saltpetre), 15% charcoal, and 10% sulphur. When ignited, it creates hot gases and a lot of energy, launching the shell out of the tube.
Some larger Roman candles add more lift to the highest layers and less to the lower layers to ensure that the stars lift to the same altitude. Some very large Roman candles load comet shells instead of stars. The stars of Roman candles can be found in a variety of colours, manipulated by adding compounds that, when ignited, release visible light and other radiation. For example, when potassium perchlorate is used as an oxidiser, chemical reactions create barium compounds that emit green light.

Roman candles were first mentioned in a 1769 Public Advertiser
Roman candles are a traditional type of firework that propels one or more stars or exploding shells into the sky. They are cylindrical in shape and are constructed with bentonite, lifting charge, pyrotechnic stars, black powder, and delay charge.
The firework gets its name from a gruesome torture method employed by the Romans, particularly the emperor Nero, who was known for burning Christians at the stake. The victims were coated in pitch, oil, wax, and other flammable materials, and lit on fire to be used as human candles. The Roman candles were used to light formal parties within the imperial gardens, prolonging the torture and pain of the victims.
Despite the name, the traditional firework actually originated in China. The first mention of Roman candles was in a 1769 Public Advertiser, which described \"a piece called The Fort with brilliant Fountains, Roman Candles, and Chinese Fires." Over time, Roman candles became a popular firework, as evidenced by their mention in various historical sources, including the 1784 London Magazine, the 1799 Artist's Arcanum, and the 1834 novel "Peter Simple" by F. Marryat.
Today, Roman candles continue to be a part of fireworks displays, although they have been banned in some countries due to their tendency to malfunction. They remain illegal to possess or set off in several US states, including California, Florida, New York, and Massachusetts.

The traditional firework originated in China
Fireworks are low explosive pyrotechnic devices used for aesthetic and entertainment purposes. They are most commonly used in fireworks displays, combining a large number of devices in an outdoor setting. Such displays are the focal point of many cultural and religious celebrations. Fireworks take many forms to produce four primary effects: noise, light, smoke, and floating materials (most notably confetti).
Traditionally, Chinese people believed that fireworks could ward off evil spirits and because of this, they are a major custom around public holidays, weddings, funerals, and other traditional ceremonies. One of the more popular legends as to why Chinese people hold this belief is the story of a monster called “Nian,” which means "year" in Chinese. The monster was said to come along on the night of Chinese New Year’s Eve to eat people and destroy their crops. Eventually, people figured out that the monster feared fire and loud noises, so they burned bamboo in the fires until they exploded, creating a loud noise. From then on, fireworks in their simplest form were created and became a tradition of Chinese New Year.
Fireworks were produced in Europe by the 14th century, becoming popular by the 17th century. Roman candles, a type of traditional firework, are cylindrical fireworks that discharge an upward stream or fountain of coloured sparks, stars, or the like. They are constructed with bentonite, lifting charge, pyrotechnic star, black powder, and delay charge. The device is ignited from the top, pointed into the sky, away from people. Roman candles are banned in some countries, such as Finland and the Netherlands, due to their tendency to malfunction.
