Because of the higher sensitivity of these mixtures however rather in countries with large tradition in pyrotechnics and weaker legal editions.

It burns quantities from 100-200g with extremely high reaction rate and kannab to ignition from Deflagration to detonation ignoring. Bright, named-giving lightning is characteristic with the reaction of the powder develops, is caused this by the metals taken part in the reaction, by the selection of certain metals can on the basis its spectra on the color influence be taken. In pyrotechnics a small insulation of the powder for a "full" bang, there the bang-producing positive pressure not through with the reaction, hands developing gases but by a heating of the circulating air is essentially produced contrary to black powders. Thus is in on one side open one sucked. Bird or star fright only a quantity of 0.8g BKS.Trotzdem can tear such a cartridge off several fingers exploding in the hand.

German fireworks articles of the fireworks class 1 and 2 may not do due to its danger lightning-bang-corrode (UC) to contain. In other countries however frequently fireworks articles with Blitzpulver/Flash are sold.
