One of fireworking's "bibles". "Fireworks, the Art, Science and Technique", by Dr. Takeo Shimizu New 4th Edition, includes 3 new and previously unpublished appendices: "Color Producing Mechanism of Flames of Nitrate Compositions without Magnesium" "Fireworks at the PL Festival" "Studies of Japanese Senko Hanabi"
With an extensive chapter on fireworks by Barry Bush, and with a comprehensive listing of formulas for stars and many other devices. These formulas are often referenced in fireworking conversations. Input from Mike Swisher.
This is one of the go-to books for many fireworkers, and is not easily found. If you find it available online, it is probably selling for up near $200.
