22762-498 ABSTRACT OF THE DISCLOSURE Disclosed is an ignition transfer medium for interconnecting the ignition and later combustion stages of a pyrotechnic device comprising charcoal cloth on which an inorganic oxidant, such as potassium nitrate, is deposited. The medium may also include one or more additional substances to modify the burning characteristics or heat output, and as an example a medium containing 1.0 to 3.5 parts by dry weight of potassium nitrate to 1 part of charcoal cloth may also include 0.05 to 0.40 parts of picric acid. In this example, the picric acid may either be adsorbed on to the cloth fibres before the potassium nitrate is deposited on to the cloth, or the two substances may be deposited simultaneously on to the cloth from an aqueous solution.
