Pyrotechnic "star" without oxidizer In the design of a celebratory pyrotechnic (firework), there exists a gunpowder explosive charge at the center of the firework and pyrotechnic "stars" lining the circumference of the explosive. The "stars" are composed of an oxidizer and a fuel such as KNO3 oxidizer and charcoal as a fuel. If the oxidizer is removed from the "stars", is it reasonable, upon detonation, to assume that the now vapourized "star" will combust only with the detonation of the gunpowder explosive charge without the need for an oxidizer in the "star" composition?

When the interior gunpowder charge explodes, it blows the stars in all directions and ignites them.  They then burn very rapidly (perhaps explosively) giving the star effect exactly because the stars are a mixture of fuel and oxidizer.  If the stars were all fuel (carbon), they would be essentially charcoal briquettes.  In that case the center would explode, throwing (possibly) burning charcoal chunks in all directions.  This could be a truly novel approach to barbecue...
