Niepce s Incendiary Composition. Contained benz, petroleum or carbon disulfide with a small piece of metallic potassium or Ca phosphate as igniter. Potassium was later replaced with metallic sodium Ref Daniel (1902), 153... 

Igniters. A pellet composed of 26.5% K. perchlorate, 16.6% Ba nitrate, 53,9% 50/50 Zr/Ni alloy, and 3.0% et cellulose can be used to ignite solid propint grains (Ref 25), A series of mixts of K perchlorate with powd metals and other oxidizable mat were examined as substitutes for BikPdr as a gun primer. Most of the mixts tested were found to be satisfactory and to be compatible with brass and other metals (Ref 9) Incendiary Compositions. Stoichiometric mixts of K perchlorate with metals and oxidizable mat have been proposed as incendiaries of the Thermit type and have heats of reaction as follows Al dust 2504, powd Mg 2429. red P 1477, powd S 705 and powd C (lampblack) 1118cal/g (Ref 4). A mixt of 12.5% K perchlorate, 75% powd Zr, and 12,5% of a 50/50 Al/Mg alloy is reported to be a readily-ignited incendiary (Ref 20). Mixts of powd Al and/or powd Fe with K perchlorate with 1.5—2% NC as a binder are also good incendiaries (Ref 35). 

In the manufacture of fast cord the first process is to coat paper or textile yarns with a blackpowder/nitrocellulose dope by a dipping process. These yarns are thoroughly dried and a number of them passed through an extruder and given a thick covering of plastic incendiary composition. The cord thus produced is covered with a protective layer of plastic, usually polyethylene. The overall diameter of the cord is about 2-5 mm. 

The speed of burning of fast igniter cord depends on the speed of burning of the blackpowder-coated yarns and this depends in turn on the gas channels left in the construction of the fuse. The remainder of the fuse is also combustible, so that there is no pressure build up due to lack of venting. Should a minor pin hole or break in the outside layers be produced and water enter, the incendiary composition will continue to burn so that the fuse will not fail, although it will slow down for the distance of the damage. 

Slow igniter cord consists of the same type of plastic incendiary composition extruded not over combustible blackpowder-coated yarns,... 

Thermite mixtures have foimd application as incendiary compositions and spot-welding mixtures. They are also used for the intentional demolition of machinery and for the destruction of documents. Thermites are usually produced without a binder (or with a minimum of binder), because the gaseous products resulting from the combustion of the organic binder will carry away heat and cool the reaction. 

The priming or igniting composition which ignited on impact consisted of Mg, KC103 and Sb2S3, while the incendiary composition contained Mg, Al, Ba(C103 )2, sulfur and a little NC... 

API), has the lead point filler replaced by an incendiary composition. It is also used primarily against aircraft. The API bullet is similar to (I), except that the incendiary is ahead of the steel core. The cal. 50 API bullet contains 15 grains of the incendiary mixture consisting of barium nitrate and aluminum-magnesium powder. This mixture ignites on impact... 

A more complicated tracer-incendiary shell was used by the British and Germans. In this shell (usually 75mm), the flash from the time fuse was transmitted through a tube (located in the center of the cylinder and extending from the top, near the fuse, almost to the bottom of the shell) to the primer. The primer ignited the incendiary composition, containing Mg, Ba(N03 )2, and binder with or without Sr(N03)2, and blew out the base of the shell. This resulted in emission of flame from the base of the shell, lasting about 15 seconds...

A description in cypher of the composition of black powder in the treatise De nullitate magiae 12 which is ascribed to Roger Bacon has attracted considerable attention. Whether Bacon wrote the treatise or not, it is certain at any rate that the treatise dates from about his time and certain, too, that much of the material which it contains is to be found in the Opus Majus. The author describes many of the wonders of nature, mechanical, optical, medicinal, etc., among them incendiary compositions and firecrackers.

Incendiary bullets are used against flammable targets and have an incendiary composition in the nose portion which is ignited on impact. Incendiary bullets are usually encountered in rifle calibers.
