Salute
From PyroGuide
A salute is a device primarily designed to make a loud report (bang), rather than have a visual effect, although most salutes will also have a very bright flash and may have titanium added for a cloud of sparks (titanium salute). 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 very fast burn rate, unlike black powder. Flash powder also produces a flash and a bang because it burns so fast.
A display of timed aerial salutes exploding in series is called a battle in the clouds.
