Acetone (2-Propanone) [C3H6O]
Flammable liquid used as a solvent in pyrotechnics (i.e., in mixtures that can't contain water). Nitrocellulose can be dissolved in it to create nitrocellulose lacquer, which can be used as an adhesive or a waterproof coating. Acetone is hard to work with because it evaporates so quickly, thus making the composition cold and causing water to condense.
Most widely used fuel in modern pyrotechnics; produces a brilliant, bright flame. The particles come in several different shapes, such as flakes and grains.
Ammonium Chloride [NH3 HCl]
Used in white smoke compositions. When burned, it decomposes into HCl (hydrochloric acid) and NH3 (ammonia), then quickly re-combines in the air to form a fine smoke of ammonium chloride particles.
Ammonium Nitrate [NH4NO3]
Oxidizer used in high explosives (such as ANFO), but not commonly used in fireworks due to its hygroscopicity.
Ammonium Perchlorate [NH4ClO4]
Slow-burning, widely-used oxidizer. Though many rich colors can be made with it, the burn rate is too slow for use in star compositions. However, it is ideal for use in lances and torches, where slow-burning is an advantage. Since all of the decomposition products are gases, it is also used in rocket propellants (such as the Solid Rocket Boosters on the Space Shuttle).
Antimony Trisulfide (antimony sulfide, realgar) [Sb2S3]
A fuel sometimes used in glitter and fountain compositions to create the color white. At one point it was used in flash compositions, but it was poisonous and extremely sensitive to shock and static electricity. Comes in two forms - "Chinese Needle" and "Dark Pyro." The former is used in glitter compositions and white comets/stars. The latter is used to sharpen the report of salutes and increase the sensitivity of flash powder.
Barium Carbonate [BaCO3]
Functions as a green color agent when burned with chlorine present (from the formation of BaCl+), burns white by itself (with oxygen, creating BaO). Can also be used to reduce acidity in chorate-based color compositions.
Barium Chlorate [BaClO3 ]
Used as an oxidizer in green color compositions.
Barium Nitrate [Ba(NO3)2]
Can be used as both a green color agent and an oxidizer. Functions as a green color agent when burned with chlorine present (from the formation of BaCl+), burns white by itself (with oxygen, creating BaO).

Boric Acid [H3BO3]
Weak acid in a powder form which is added to compositions containing aluminum or magnesium and a nitrate. Metals react with nitrates to form amides, which can further react with the metal powder to create a highly exothermic reaction which could spontaneously ignite the compound. Even a few percent boric acid added to the mixture will neutralize any amides that form.

Charcoal (carbon) [C]
Charcoal is used very widely in pyrotechnics. Charcoal is the by-product of the burning of organic substances. It contains impurities which make it more reactive, and therefore is used more often than pure carbon in fireworks. It can be made from many types of wood. Charcoal from soft woods, such as grape vine or willow, is good for fast-burning compositions like black powder, whereas charcoal from hard woods like pine are used to create long-lasting spark effects. Very fine charcoal is known as air float. Another type of fine charcoal is called lampblack.

Alloy of magnesium and aluminum, with properties of both metals. Not quite as reactive as magnesium, and not as hard to ignite as aluminum. Used primarily in glitter, strobes, colored stars, and crackling stars.
Highly reactive and flammable metal used to brighten flames without decreasing color quality. Coarser grades are used to produce white sparks, whereas fine magnesium is used in flare and star compositions. The by-products of the burning of magnesium are more easily vaporized than those of aluminum, making magnesium a better fuel.
Mercury (I) Chloride (mercurous chloride, calomel) [Hg2Cl2 ]
This white (or yellowish-white) powder will brighten an otherwise dull colored mixture. DO NOT confuse this chemical with Mercuric Chloride, which is highly toxic.
Used as a solvent (similar to ethanol) to dissolve red gum and shellac. Is often mixed with water when used in compositions in order to reduce the surface tension of the water (thus making it more "wet").
