Yellow Stars (Metallic)

From PyroGuide

Jump to: navigation, search

These stars generally give better and more brilliant colours than compositions without magnesium/MgAl. This is because in the latter case the flame temperature is lower and the emitting molecules are not stimulated equally well. Care must be taken to adaquately protect the metals, if necessary, and to ensure good ignition as they are generally much harder to ignite. The stars show a higher burning rate than organically fuelled ones.

Note that with some comps water must not be used for consolidation for there would be reactions with magnesium (with heat and hydrogen gas generation) in such a case.
