Used together with colorants. In some cases, the color emitting species is molecular and not atomic. Such is the case for blue pyrotechnic flames where the emitting species is copper monochloride. Also, some chloride molecular emitters are much stronger than oxides of the same element, as in the case of Barium and Strontium.
Additionally, accidental contaminants such as strong acids or sulfur compounds can sensitise them even more. Because flash powder mixtures are so easy to initiate, there is potentially a high risk of accidental explosions which can inflict severe blast/fragmentation injuries, e.g. blindness, explosive amputation, permanent maiming, or ...
The BaOH lines are much stronger than the BaO lines. In absence of chlorine, the BaCl lines are not present and only the BaOH and BaO lines are visible. The BaCl species tends to be oxidized to less desirable BaO; barium-containing compositions are therefore usually formulated to be oxygen-deficient.
Pyrotechnic gerbs used in the entertainment industry. Pyrotechnics is the science and craft of creating such things as fireworks, safety matches, oxygen candles, explosive bolts and other fasteners, parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition.

1.4 Consumer Display Rocket. A rocket is a pyrotechnic firework made out of a paper tube packed with gunpowder that is propelled into the air. Types of rockets include the skyrockets, which have a stick to provide stability during airborne flight; missiles, which instead rotate for stability or are shot out of a tube; and bottle rockets, smaller fireworks – 1½ in (3.8 cm) long, though the ...

The salute may be fired on the ground (ground salute) or launched from a mortar as a shell (aerial salute). Due to the nature of the effect, large salutes are some of the more hazardous fireworks. Most of the "salutes" are made with flash powder. Flash powder has a fast burn rate, unlike black powder.
