Flower pot is a slang term for an aerial shell exploding in it's mortar. When this happens, the effect will be like a mine. Since a flowerpot is not a desired effect, the aerial shell is sometimes powerful enough to break the mortar. Most commonly this is caused because;
Flash powder is a mixture of oxidizer and metallic fuel which burns extremely quickly and if confined will produce a loud report. It is widely used in fireworks and theatrical pyrotechnics, and was once used for flashes in photography.
Of all of the available effects to the pyrotechnist, flash powder is probably the most primitively attractive, and certainly the deadliest effect we have. Perhaps this is due to the awesome energy potentials, the blinding flashes and the heart stopping blasts furnished by it. I bet that more people in the pyro trade have made flash before they have made stars or aerial shells.
A flare (or fusee) is described as a luminous device, that produces a brilliant light or intense heat without an explosion. Flares are used for signaling, illumination, or defensive countermeasures in civilian and military applications.

Falling leaf fuse is most commonly used for various coloured effects fireworks even though it can be used in place for regular visco fuse. It is a cord with a pyrotechnic composition core that burns green, red, purple, blue, yellow or white. There are three layers that make up the fuse.
An explosive substance is a solid or liquid substance (or a mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to surroundings. Pyrotechnic substances are included even though they do not produce larges volumes of gases.
An explosive is a substance or thing containing a substance, manufactured or used with a view to produce -
