Some examples of low level fireworks are comets, mines, roman candles, and many consumer fireworks.
Manual Ignition A technique used to ignite fireworks using a handheld ignition source such as a fusee or portfire.
Mine A device containing multiple pyrotechnic effects that are simultaneously ignited and dispersed into the air from mortar or tube.
