Golden chrysanthemumA spherical break of stars, similar to a peony, but with stars that leave a visible trail of sparks. A common composition to give the trails are slow burning gunpowder mixtures. The addition of large amounts of charcoal causes thousands of glowing charcoal sparks. The sparks are made alive at first by the action of nitrates on the charcoal then the air supplies oxygen later on in the sparks life. Metals such as Aluminium, Titanium, Magnalium, Ferrous metals and Ferrotitanium can also be used as spark producing materials. More advanced Chrysanthemum shells may have stars with coloured cores. A shell which produces a spherical burst of stars which change from a trail effect to, say purple, could be called a Purple Chrysanthemum.
