COVER PICTUREThe cover picture shows the burning of an environmentally friendly M159 pyrotechnic illuminant composition for military signaling.This illuminant may also be of interest to the civilian fireworks industry.The illuminant is free of heavy metal barium and toxic Laminac binder system, and has a low sensitivity to various ignition stimuli.The new illuminant burns 1.12 times longer, 2.93 times brighter, and with 3.25 times the luminous efficiency compared to the bariumcontaining M159 control.The top-left picture depicts an M159 illuminant tested statically at mid-burn.The top-right picture shows a midburn profile during ballistic mortar testing of the new 5-star cluster M159 illuminant.The bottom picture depicts yellow light-emitting fireworks during a Macy's 4th of July display in New York City.
