Toy pistol caps

Potassium chlorate was used in the first successful colored-flame compositions in the mid-1800 s and it remains in wide use today in colored smoke, firecrackers, toy pistol caps, matches, and color-producing fireworks. 

The detonator (discriminating impact fuse) is a brass cup 3/16 V3/16 The wall thickness is about half that of a conventional primer. The Interior of the cap Is coated with a shock sensitive explosive, probably the same composition found in toy pistol caps (Pottasiym Chlorate, Red Phosphorus and Black Antimony Sulfide). The volume used is also about that of a toy cap. The cup is seated open end to the rear and is recessed about... 

In view of this the red phosphorus which is used to toy pistol caps etc. must be thoroughly purified from phosphoric acid. 

Potassium perchlorate becomes sensitive in contact with red phosphorus the mixture detonates with a loud noise by an impact between metal pieces of aluminium or bronze. When the mixture is ignited, it detonates instantaneously. However match or toy pistol caps cannot be made from compositions which contain potassium perchlorate in place of chlorate, because the ignition is uncertain. When potassium perchlorate is mixed with realgar, antimony trisulphide, sulphur etc. it also becomes sensitive realgar particularly increases the sensitivity to friction. But the degree of sensitivity is not as large as it is with potassium chlorate. 

This kind of composition is used for toy pistol caps(arranged on... 

Toy pistol caps contain red phosphorus and potassium chlorate in separate compartments which, when struck together, will explode. 

Russia and other counrries it. has been used for prepn of "snaps", "pull-crackers", paper caps for toy pistols and "jumpiog frogs". Also in amusement devices such as "cigars" and "spiders". If a few grains of wet SF are spread on a floor, loud cracks are heard if they are walked upon (See Beil 1, 722 and AddnlRefs for SF)... 

B) includes noise compositions which are quite sensitive and snake compositions which exhibit curious phenomena, etc. It can be seen from the diagram that toy firework compositions, (A+B), are more numerous than those for ordinary fireworks (A). The reason is that, in the case of toy fireworks it is possible to increase the safety of the compositions to a high degree by complete division and isolation. Following this principle even some sensitive compositions which are never used for shells, exhibition fireworks etc. can be used for toy fireworks. For example, a composition which contains potassium chlorate and red phosphorus is used for pistol caps or another compositon which contains potassium chlorate and realgar is used for cracker balls. These compositions are generally used only for toy fireworks.

Toy pUtols inive been iniide which project a buckshot with considerable force by tlie explosion of a percussioii-cap. Toy pistols tor firing an arro v by tho force ofaspiing, or projecting ii cork by the expansion of air which bus boeu previously compressed in a chamber, are also roiiiinon. 

Amorce is a French word that means cap, primer, detonator, or fuse, terms that differ from the English usage of amorce used to describe the toy caps used in toy pistols or thrown down sharply in play. They contain extremely small quantities (around Img) of shock sensitive explosive mixtures of potassium chlorate and arsenic monosulphide or silver fulminate. Trick matches are toys that are extremely difficult to blow out.
