Welcome to the Pyrotechnics 101

This is a planning page for a future course to be taught at Monmouth College. The course will be taught by a chemistry professor and the campus' lead electrician.

The rules that regulate the fireworks in the state of Illinois can be found here

Fireworks are classified as a hazardous material (HAZMAT) class 1.3. The United Nations classification system can be found here; the classification by the United States Department of Transportation (DOT) can be found here. Consumer grade fireworks (where allowed are classified as 1.4.

Possible Textbooks

Both instructors are employees of J&M Displays

Topics

Chemistry

Oxidizer (species being reduced)
Potassium nitrate (2 NO3- --> N2 + 3 O2)
Potassium Perchlorate
Reducer (Fuel; species being oxidized)
Magnesium powder (Mg--> Mg2+)
Aluminum powder (Al --> Al3+)
