These are used to create the colors in pyrotechnic compositions like fireworks and colored fires. The color-producing species are usually created from other chemicals during the reaction. Metal salts are commonly used; elemental metals are used rarely (e.g. copper for blue flames).
Salt/common salt – a mineral, sodium chloride, NaCl, formed by evaporating seawater (impure form). Salt of tartar – potassium carbonate; also called potash. Salt of hartshorn/sal volatile – ammonium carbonate formed by distilling bones and horns. Tin salt – hydrated stannous chloride; see also spiritus fumans, another chloride of tin.
Pyrotechnic stars are pellets of pyrotechnic composition which may contain metal powders, salts or other compounds that, when ignited, burn a certain color or make a certain spark effect. They are a part of all projectile-type fireworks. The most common is the aerial shell.
Strontium chloride (SrCl 2) is a salt of strontium and chloride.It is a 'typical' salt, forming neutral aqueous solutions. As with all compounds of strontium, this salt emits a bright red colour in flame, and is commonly used in fireworks to that effect.
Colored fire is a common pyrotechnic effect used in stage productions, fireworks and by fire performers the world over. Generally, the color of a flame may be red, orange, blue, yellow, or white, and is dominated by blackbody radiation from soot and steam.
The documents revealed that DuPont had used the landfill near the Tennants’ farm as part of an increasingly elaborate cover-up. After discovering C8 in Lubeck’s water supply in the early 1980s, DuPont had dredged up 14 million pounds of C8-laced sludge from the unlined pits near the town wells and dumped it into the Dry Run landfill.
Aluminium metal is used to produce silver and white flames and sparks. It is a common component of sparklers. Ba: Barium: Barium salts are used to create green colors in fireworks, and it can also help stabilize other volatile elements. C: Carbon: Carbon is one of the main components of black powder, which is used as a propellent in fireworks.
