Luminescent agent - Hakkozai

Japanese: 発光剤 - はっこうざい
Luminescent agent - Hakkozai
Chemicals used to produce light. There are flaming agents, spark agents, and spark powder agents. Flaming agents produce a spectrum of atoms and molecules due to high-temperature gas reactions, and there are low-temperature types with temperatures of 1700-2300°C and high-temperature types with temperatures of over 2700°C. Low-temperature types are used in traditional fireworks and produce a relatively weak light. Potassium chlorate, potassium perchlorate, ammonium perchlorate, etc. are used as oxidizers, and shellac, red gum, etc. are used as combustion improvers (oxidized agents).
