Oxidiser
Click to Enlarge. It’s Fireworks Night here in the UK tomorrow, which means fireworks (obviously), bonfires and sparklers. We’ve looked at fireworks in a previous post, so this time around it’s time to take a look at the chemicals that go into producing sparklers, and their various roles. In sparklers, there are three main components to the composition: a metal fuel, an oxidiser, and a binder. The temperature of the burning sparkler can easily reach between 1000-1600˚C, and the use of additional fuels can also have an effect on this. Regardless of your previous chemistry education, you probably came across the concept of oxidation and reduction reactions. We summarised some of the different compounds that can be used for this purpose in the older post on the colours of fireworks. Of course, the metal powder and the oxidiser would be useless without a way to bind them together into a paste that can then be added onto the metal rod that forms our sparkler. The temperature of the burning sparkler can easily reach between 1000-1600˚C, and the use of additional fuels can also have an effect on this. Regardless of your previous chemistry education, you probably came across the concept of oxidation and reduction reactions. Fireworks are a class of explosive pyrotechnic devices used for aesthetic, cultural, and religious purposes. A fireworks event (also called a fireworks show or pyrotechnics) is a display of the effects produced by firework devices.  Sulfur-Sulfur is a component of black powder. It is found in a firework's propellant/fuel. Strontium-Strontium salts impart a red color to fireworks. Strontium compounds are also important for stabilizing fireworks mixtures. Titanium-Titanium metal can be burned as powder or flakes to produce silver sparks. Iron-Iron is used to produce sparks. The heat of the metal determines the color of the sparks. Lithium-Lithium is a metal that is used to impart a red color to fireworks. Lithium carbonate, in particular, is a common colorant. Magnesium-Magnesium burns a very bright white, so it is used to add white sparks or improve the overall brilliance of a firework. Oxygen-Fireworks include oxidizers, which are substances that produce oxygen in order for burning to occur. The oxidizers are usually nitrates, chlorates, or perchlorate In the United Kingdom, a sparkler is often used by children at bonfire and fireworks displays on Guy Fawkes Night, the fifth of November, and in the United States on Independence Day (United States) . A sparkler is a type of hand-held firework that burns slowly while emitting colored flames, sparks, and other effects. what is the name of the powdery chemical use to create sparklers.

Let's put it all together: A sparkler consists of a chemical mixture that is molded onto a rigid stick or wire. These chemicals often are mixed with water to form a slurry that can be coated on a wire (by dipping) or poured into a tube. Once the mixture dries, you have a sparkler. In addition to these components, colorants and compounds to moderate the chemical reaction also may be added. Often, firework fuel is charcoal and sulfur. Sparklers simply may use the binder as the fuel. The binder is usually sugar, starch, or shellac. A variety of chemicals can be added to create colors. The fuel and oxidizer are proportioned, along with the other chemicals, so that the sparkler burns slowly rather than exploding like a firecracker. Once one end of the sparkler is ignited, it burns progressively to the other end. In addition to these components, colorants and compounds to moderate the chemical reaction also may be added. Often, firework fuel is charcoal and sulfur. Sparklers simply may use the binder as the fuel. The binder is usually sugar, starch, or shellac.
