Roman candles are traditional tube-shaped fireworks that eject one or more exploding stars into the sky. They are constructed with bentonite, lifting charge, pyrotechnic star, black powder, and delay charge. The fireworks are lit from the top and should be pointed upwards, away from people. Roman candles come in a variety of sizes, with larger candles producing bigger explosions. They are banned in several countries and US states due to their potential to malfunction. It is important to follow safety precautions when using Roman candles, such as not holding them in your hand unless specified, placing them securely in the ground or a container, and keeping them away from flammable objects and bystanders.

What You'll Learn
Prepare your candle and space
To prepare your candle and space for shooting off a Roman candle firework, follow these steps:
Firstly, always read the instructions on the Roman candle. Most Roman candles are not meant to be held in your hand, but some are. If the candle is not designed to be held, you will need to find something to place it in. You can stick it in the ground or place the end in a glass jar or another container. Alternatively, you can place a pipe in the ground and set the candle inside it. This way, you can use the pipe to shoot off other fireworks, such as bottle rockets.
Next, ensure you have prepared a safe space. Roman candles should always be used outdoors and away from flammable materials, people, pets, and structures. Keep the fireworks away from power lines, trees, and anything else that could catch on fire. Check the regulations in your city, as some cities prohibit the use of fireworks within city limits or during burn bans.
Now, you should prepare your candle. Roman candles are typically constructed with a cardboard tube, sealed at the bottom, and lit by a fuse from the top. The candle should be pointed towards the open sky, as most Roman candles shoot out coloured stars that can ignite things if they don't burn out first. You can reinforce the tube by wrapping it with paper or masking tape, ensuring the charge shoots up and out of the tube rather than splitting the cardboard.
Finally, before you light the candle, make sure you are sober and use good judgment. Roman candles can be dangerous and should always be handled with care.

Light the candle
Lighting a Roman candle is a potentially dangerous activity and should be done with care and attention. Roman candles are a traditional type of firework that ejects one or more exploding stars or shells into the sky. They are simple in construction but are not a beginner-level project.
To light the candle, firstly, ensure you are sober and that there are no flammable materials, people, pets, or structures nearby. Roman candles are ignited from the top, so point the top into the open sky, away from people and flammable objects. The candle should be placed on the ground or in a glass jar or pipe, which should be stuck into the ground.
The candle is lit by a fuse from the top, which burns down to light successive charges. Once lit, get clear of the candle and keep your distance. The firework will burn and then go out by itself. If you are holding the candle, you must put it down on a hard, non-flammable surface when the fire gets close to your hand.
It is important to note that Roman candles are banned in some countries and prohibited in certain U.S. states, so always check local regulations before attempting to light one.

Safety precautions
Roman candles are 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 device is ignited from the top, which should always be pointed into the sky, away from people.
Read the instructions: Always read the instructions on the Roman candle before lighting it. Some Roman candles are safe to hold in your hand, but most are not. If the candle says not to hold it in your hand, do not attempt to do so.
Secure the candle: If the Roman candle is not meant to be held in your hand, find a safe place to secure it. You can stick it in the ground, place the end in a glass jar or another container, or set it in a pipe stuck in the ground. Make sure the candle is pointed toward the open sky to avoid igniting anything or anyone.
Be cautious of malfunctions: Roman candles have a tendency to malfunction, which is why they are banned in some countries and states. Always purchase your Roman candles from a reputable source, and check for any recalls or safety warnings before lighting.
Avoid alcohol: Do not consume alcohol or other substances before or while shooting Roman candles. This can impair your judgment and reaction time, increasing the risk of accidents.
Never attempt to take the candle apart: Do not try to disassemble the Roman candle or alter it in any way. This can compromise the integrity of the firework and increase the risk of malfunction.
Be mindful of your surroundings: Ensure there are no flammable materials or dry vegetation nearby that could catch fire. Keep a safe distance from buildings, vehicles, and other people. Also, be aware of the wind direction and speed to prevent sparks or debris from reaching unintended areas.
Remember, Roman candles and all fireworks can be dangerous if not handled properly. Always follow local laws and regulations regarding the use of fireworks, and prioritize safety at all times.

Candle construction
Roman candles are traditional tube-shaped fireworks that shoot exploding stars into the sky. They are constructed with bentonite, a lifting charge, a pyrotechnic star, black powder, and a delay charge.
The candle consists of a cardboard tube that is sealed at the bottom and lit by a fuse from the top. The delay powder is packed tightly in the tube so that the flame cannot reach around the sides of the plug of the delay composition. The delay charge is made of tissue paper, sawdust, or a small amount of clay that is pressed on top of the ball. This prevents additional layers of material from burning all at once, so each charge shoots into the air.
The tube should be wrapped with paper or masking tape to reinforce it and ensure that the charge shoots up and out of the tube. The bottom of the tube should be sealed with a clay plug to prevent the charge from escaping through the bottom. A fuse is then run down the tube to the clay plug.
Finally, add a layer of black powder and the "star" composition, which can be made from the coatings of sparklers, flash powder, and black powder or Pyrodex. Repeat these layers until the tube is filled.

Different types of candles
Roman candles are traditional tube-shaped fireworks that launch exploding stars or shells into the sky. They come in a variety of sizes, colours, and effects. The colours are manipulated by adding compounds that release visible light and other radiation when ignited. For example, barium compounds emit green light, while strontium compounds emit red light.
Roman candles can be as small as 6 mm in diameter or as large as 8 cm for professional displays. The larger the candle, the bigger the explosion, and the more stars it will contain. Some very large Roman candles load comet shells instead of stars.
Chinese Roman candles often use clay instead of delay powder and have a fuse down the centre to time the lifts. They are also known for their quietness, making them ideal for families with young children or noise-averse adults.
Roman candles can be hand-held or placed on the ground, in a jar, or a pipe. They should always be pointed towards the open sky when ignited, as they shoot out coloured stars that can ignite things if they don't burn out first. It is important to follow local regulations and safety guidelines when using Roman candles and other fireworks.
