Sparkler candles, or sparklers, are a type of hand-held firework that emits bright, coloured sparks. They are formed around a thin, non-combustible metallic wire that is about 8–12 inches (20–30 cm) long. The wire is dipped in a thick batter of slow-burning pyrotechnic composition and allowed to dry. The sparks are created by glowing metal particles, usually aluminium, undergoing combustion. Sparklers are often used at celebrations and are particularly popular with children. They are used in the United Kingdom during Guy Fawkes Night and in the United States on Independence Day.

Sparkler candles are a type of hand-held firework
Sparklers are commonly used for celebrations and are especially popular with children. They are often used at bonfire and fireworks displays, such as Guy Fawkes Night in the United Kingdom and Independence Day in the United States. In Hindi, sparklers are called "phuljhadi" and are widely used during the Diwali festival.
Despite their small size, sparklers can be dangerous due to their high burning temperature, which can exceed 1000°C. They have been associated with a significant proportion of firework-related injuries, especially among young children. As such, safety experts recommend that adults supervise children who are handling sparklers and ensure they wear non-flammable clothing.
Sparkler candles are also used for decorative purposes, such as on birthday cakes, adding a festive touch to celebrations. They are available in various forms, including numbers, letters, and star shapes, enhancing the visual appeal of the occasion.
Overall, sparkler candles are a fun addition to celebrations, providing a dazzling display of sparks that delights both children and adults alike. However, it is essential to prioritise safety measures when using these miniature fireworks to prevent accidents and injuries.

They are used for celebrations and are popular with children
Sparklers are a type of hand-held firework that emits bright, coloured sparks while burning slowly. They are a popular feature of celebrations and are especially enjoyable for children. Sparklers are often used at birthday parties, weddings, and national holidays. They are also used to create light paintings and ignite thermite, thanks to their high burning temperature of over 1000°C.
In the United Kingdom, sparklers are traditionally used by children during bonfire and fireworks displays on Guy Fawkes Night, the fifth of November. Similarly, in the United States, sparklers are popular with children on Independence Day. Sparklers are also called "phuljhadi" in Hindi and are widely used during the Diwali festival.
The appeal of sparklers to children is undeniable, but it is important to prioritise safety. Sparklers burn at extremely high temperatures, ranging from 1000°C to 1600°C, which is more than enough to cause severe skin burns or ignite clothing. In 2003, the U.S. Consumer Product Safety Commission reported that sparklers were involved in 57% of fireworks-related injuries sustained by children under five years of age. To ensure a safe experience, adults should provide proper supervision, ensure children are wearing non-flammable clothing, and provide clear warnings about the potential dangers.
The colourful and sparkling nature of sparklers makes them a delightful addition to any celebration. They are often used on cakes and cupcakes for birthdays and other special occasions. The sparklers are stuck into the cake, and onlookers can enjoy the shower of sparks they produce. The sparkles are created by glowing metal particles, usually aluminium, undergoing combustion and reacting with oxygen to form metal oxides. Other metals used in sparklers include iron, titanium, zinc, and magnesium, each influencing the colour and intensity of the sparks.

Sparklers are formed around a thin, non-combustible metallic wire
Sparklers are a type of hand-held firework that emits bright, colourful sparks while burning slowly. They are particularly popular among children and are used during celebrations and festivities such as Guy Fawkes Night in the United Kingdom and Independence Day in the United States. They are also called "phuljhadi" in Hindi and are widely used during the Diwali festival.
Sparklers are constructed around a thin, non-combustible metallic wire, typically measuring 8–12 inches (20–30 cm) in length. This wire serves as the foundation to which other components are attached. The wire is carefully dipped into a thick batter, a slow-burning pyrotechnic composition, and then allowed to dry. This process ensures that the combustible coating adheres securely to the wire, creating the foundation for the sparkler's brilliant display.
The combustible coating on the wire contains various metallic fuels, which serve as the main reactive ingredients. Different types of metals are used, including aluminium, magnesium, or a combination of both, known as magnalium. These metals influence the colour of the sparks produced, with aluminium and magnesium producing white sparks. Other metals such as iron, titanium, zinc, or magnesium can also be used, each contributing to unique spark colours.
The metallic particles are bound to the wire using dextrin, a natural glue-like substance. Dextrin is a carbohydrate composed of short chains of glucose molecules, derived from the partial breakdown of starch. It plays a crucial role in holding the metal particles and potassium perchlorate securely onto the wire. Additionally, dextrin burns during the combustion process, generating heat that aids in the decomposition of the perchlorate, thus enhancing the overall combustion of the metal.
The sparkler's intense glow and shower of sparks are a result of the metallic particles undergoing combustion and reacting with oxygen to form metal oxides. Potassium perchlorate, an oxidizing agent, provides the additional oxygen required for this intense reaction. When the sparkler is lit, the potassium perchlorate undergoes a chemical reaction, decomposing into potassium chloride and releasing oxygen. This oxygen then combines with the metal, allowing it to burn brightly and create the captivating display of sparks that sparklers are known for.

They burn at a high temperature, over 1000°C, and emit sparks
Sparklers are a type of hand-held firework that burns slowly, emitting bright, colourful sparks. They are formed around a thin, non-combustible metallic wire, usually between 8 and 12 inches (20-30 cm) long. This wire is coated in a slow-burning pyrotechnic composition, which includes metallic fuel and an oxidising agent, such as potassium perchlorate, which helps the metal burn brighter by providing a source of oxygen. The type of metal used influences the colour of the sparks, with aluminium, magnesium or magnalium producing white sparks. Other metals used include iron, titanium and zinc.
The bright sparks are caused by the combustion of these metal particles, which burn at an extremely high temperature—over 1000°C. This is why sparklers can be dangerous, capable of causing severe skin burns or igniting clothing. In fact, safety experts advise that children who handle sparklers should be properly warned, supervised, and wearing non-flammable clothing. Sparklers have been known to cause wildfires, particularly in dry areas, and can even cause severe injuries, especially to young children.
The intense heat of sparklers also means they can be used to ignite thermite. This property has been utilised in solid-fuel boosters for the Space Shuttle, which essentially used giant sparklers, filled with a mixture of aluminium powder and ammonium perchlorate.
