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).
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.
Barium chromate – used in delay compositions, e.g. in fireworks rockets; Lead chromate – used in delay compositions; Potassium dichromate – used infrequently as an oxidizer; can be used as a surface treatment for passivation of magnesium particles, also as a catalyst and in some matches; potassium perchlorate often added; Oxides and ...

Solid salts have long been used as paint pigments, and are resistant to organic solvents, but are sensitive to acidity or basicity. [89] Since 1801 pyrotechnicians have described and widely used metal-containing salts as sources of colour in fireworks. [90] Under intense heat, the electrons in the metal ions or small molecules can be excited. [91]

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.
Children between the ages of 15 and 19 have the highest rate of fireworks-related ER visits, followed by kids ages 5 to 9. It's worth noting that 66% of fireworks injuries happened in the weeks ...
