I just discovered the website for the Journal of Pyrotechnics:

Issues of the Journal of Pyrotechnics [ISSN 1082-3999] appear twice a year. Early issues contained 40 to 50 pages. More recent issues contain 70 to 80 pages printed in 8-1/2×11″ format with medium-sized print. Areas of pyrotechnics addressed include fireworks, pyrotechnic special effects, propellants & rocketry, and civilian pyrotechnics. The Journal is “dedicated to the advancement of pyrotechnics through the sharing of information”. This is accomplished with a mix of different types of articles; however, most fall into two areas. One area is reports on pyrotechnic and fireworks research conducted by both professional scientists and individual experimenters. The other area is reviews of various technical and craft areas of pyrotechnics, some at an advanced level and others at a tutorial level.

At $25-40 per issue, this is clearly an industry-priced publication. PDFs of articles can be bought at .50 per page.
