New York: American Fireworks News, 2000. — 208 p.
Best IV contains some truly advanced pyrotechnic information, such as mortar separations, and fusing problems, and other display situations. But we managed to keep some basic material available too, and a whole bunch of how-to articles. We are very pleased with some of these how-to articles, because they show how easily obtained Consumer Fireworks items can be used to make display-quality devices.
