Roman candles are a traditional type of firework that ejects one or more stars or exploding shells. They come in a variety of sizes, with smaller candles designed for consumers and larger ones for professional displays. Roman candles are constructed with bentonite, lifting charge, pyrotechnic stars, black powder, and delay charge. The firework is ignited from the top, pointed upwards and away from people. Setting off a Roman candle involves a chain reaction of delay charges, igniting stars, and lift charges. While Roman candles are widely used, they are banned in some countries and states due to safety concerns. It is important to follow local laws and safety guidelines when using Roman candles.

Roman candles are constructed with bentonite, a lifting charge, a pyrotechnic star, black powder, and a delay charge
Roman candles are a traditional type of firework that ejects one or more stars or exploding shells. They come in a variety of sizes, from 6 mm (0.24 in) in diameter for consumers to 8 cm (3.1 in) in diameter for professional displays. Roman candles are banned in some countries due to their tendency to malfunction. They are illegal to possess or set off in several US states.
Some variations of Roman candles use clay instead of delay powder and run a length of fuse down the inside of the candle to time the lifts. Larger candles (three-inch diameter or more) usually add more lift to the highest layers and less to the lower layers to ensure the stars are lifted to the same altitude. This is due to the shorter length of tube available for accelerating the higher stars. Some very large Roman candles load comet shells instead of stars.
The stars of Roman candles can be found in a variety of colours. These colours are manipulated by adding compounds that, when ignited, release visible light and other radiation. For example, when potassium perchlorate (KClO4) is used as an oxidizer, chemical reactions involving the dissociated elements of the perchlorate—potassium and chlorine ions—create barium compounds that emit green light. The potassium compounds formed by this reaction emit mostly near-infrared light, so they do not affect the colour of the star.

Roman candles are a traditional type of firework constructed with bentonite, lifting charge, pyrotechnic star, black powder, and delay charge. They are ignited from the top, pointing into the sky, away from people.
To set off a Roman candle safely, it is important to keep a safe distance. Use an extended lighter or a punk to light the candle, and do not hold it in your hand, even if the instructions suggest this. The likelihood of catastrophic consequences may be low, but it is not a risk-free activity. If you do choose to hold the candle, grip the bottom few inches firmly and keep it away from your face.
It is also important to keep a fire extinguisher and a bucket of water nearby, just in case. Always follow the instructions on the box, as each Roman candle is different. Be sure to check your local laws before lighting a Roman candle, as they are banned in some countries and states.
When setting up the candle, it should be secured on the ground so it cannot fall over. Stake it directly into the ground or use a tube to fire it off from. Roman candles should be pointed into the sky, away from people.

Roman candles come in a variety of sizes, from 6mm to 8cm in diameter
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, a pyrotechnic star, black powder, and a delay charge. The delay powder is packed tightly in the tube, so the flame cannot reach around the sides of the plug of delay composition. This means it burns slowly, and as it is consumed, the flame moves down the tube.
Roman candles come in a variety of sizes, from 6mm (0.24 inches) in diameter for consumers, to 8cm (3.1 inches) in diameter for professional fireworks displays. The larger candles usually add more lift to the highest layers and less to the lower layers, to ensure the stars are propelled to the same altitude. The smallest candles are ideal for creating coloured star effects and crackling comets. They are also useful for creating low noise, as the small bore size means the sound of the lift charge will not travel far.
Larger candles cost more, with single or twin-shot candles priced at under £10, bigger candles at £10-£30, and bundles starting at £30, depending on size and the number of shots. The number of shots can vary from several dozen to several hundred.
Roman candles are banned in some countries, including Finland and the Netherlands, and are illegal to possess or set off in several U.S. states. They can be very dangerous, and it is important to follow safety advice when using them.

Roman candles are constructed with bentonite, lifting charge, pyrotechnic stars, black powder, and delay charge. The device is ignited from the top, pointed into the sky, and away from people.
The safety concerns surrounding Roman candles are significant enough to warrant their restriction or prohibition in certain jurisdictions. These fireworks can pose risks if not used properly, and their legality varies depending on local and state laws. It is crucial to check the regulations in your specific area before purchasing or using Roman candles.
The process of igniting a Roman candle involves lighting the fuse, which initiates a chain reaction. The delay charge burns down the candle until it reaches the stars or shells, which are loosely packed. This ignition triggers the lift charge, causing the candle to pop open and launch the stars into the sky. While Roman candles can create a colourful display, their potential for malfunction has led to their ban in some places.
To safely set off a Roman candle, it is important to follow certain precautions. These include using an extended lighter or punk to maintain a safe distance, having a fire extinguisher and bucket of water nearby, and adhering to the instructions on the box. It is also crucial to never hold a Roman candle in your hand, as this can be highly dangerous. Instead, place the candle on a flat surface or stake it directly into the ground.

To make your own, cut a tube to 10, wrap it in paper, seal the bottom with clay, and layer in black powder, a star, and a delay charge
To make a Roman candle firework, you'll need to cut a tube to a length of 10 (I assume you mean 10 inches, which is a common length for consumer Roman candles). The type of tube you use will depend on the materials you have available and what you plan to fill it with. Common plumbing tubes are made from PVC, PEX, copper, galvanized steel, and cast iron. You can use tube cutters designed for the specific material of your tube, or you can use a saw. If you use a saw, make sure to secure the tube with a vise, clamp, or miter box to get a straight cut.
Once you've cut your tube, you'll need to wrap it in paper. This will provide a surface for your clay seal and delay charge to adhere to. It will also give your Roman candle a finished look.
Next, seal the bottom of the tube with clay. You can use a product like Seal-A-Tube, which is a plastic cap with a long plastic pin that goes into the tube, or you can use a blob of modelling clay. If you use clay, roll it into a thin snake and wrap it around the bottom of the tube, pinching it together to create a tight seal.
Now you can start layering in your fireworks components. First, pack in a layer of black powder. This will serve as your delay charge. You can use traditional delay powder or clay, as is common in Chinese Roman candles. Pack the powder or clay tightly so that the flame cannot reach around the sides of the plug.
Next, add your pyrotechnic star. This is the main attraction of your Roman candle. The star should fit loosely in the tube so that when it's ignited, the fire can spread around it and ignite the lift charge. You can find stars in a variety of colours, created by adding different compounds.
Finally, add your lift charge. This is what will propel your star out of the tube. Your Roman candle is now ready to be ignited! Just remember to always point it towards the sky and away from people.
