  1. Emergency Flare Amanda Baldwin, Erin Brown, & Thomas Kennington www.mclendons.com Flare Chemistry • Oxidizer • Responsible for K peaks • Produces oxygen to burn flare. • Combustible binder added to slow burn rate; produces brighter intensity • Composition • Generally 55% Mg, 38% NaNO3, and 6% binder • Ferric Oxide functions as ignition and incendiary • Color intensifiers • Lithium carbonate added to give red color. http://www.foursprung.com/2005/12/foursprung-new-flameless-flare.html K Fe Li Li Fe Na K 2Li2CO3 (s)  2 Li2CO2+O2 (g)

  2. Small Sparkler Spectra www.tradeget.com Sparklers • History of Pyrotechnics • Pyro -Greek for fire/ Techne -Greek for art • Black powder discovered • ~600-900AD in China • For 1000 years only orange flame from black powder • 1830s Italian chemists created reds, greens, blues, & yellows K Cs Na Fe • Sparkler Chemistry • Oxidizer (potassium nitrate) • 2 KNO3(s)  2 KNO2 + O2(g) • Fuel proportioned for slow burn includes powders of Al, Mg, & S • Combustible binder including: resin, wax, plastics, & oil • Color intensifiers -highly chlorinated organic compounds like hexa-chlorophene, hexa-chlorobenzene, & polyvinyl chloride.
