Description

Process for the production of crackling stones The hitherto in the trade Brought rattle stones have the disadvantage that they are due to the use of yellow and white phosphorus are both fire and explosive and toxic and as a result may not be sold to young people under the age of 16.

It has now been found through thorough experiments that the poisonous can replace yellow or white phosphorus with the almost non-toxic red phosphorus and that the chlorates and phosphorus by adding coarse quartz flour or It is possible to separate pumice flour in such a way that there is no danger of explosion or fire exists during manufacture, use, storage or transport.

This is achieved according to the invention by first the Dissolve chlorate with powdered gum arabic in water and stir for a long time. 1> 1s the mass is perfectly homogeneous; this porridge is then slowly stirred add coarse red phosphorus in powder form until it is completely moistened, and then immediately add coarse quartz or pumice flour, the effect of which is to To erect partitions between the flammable phosphor particles, through which not only the further trituration, but also the rolling up of the porridge and cutting out the panes or shapes are completely harmless. The shaped slices or Bodies are dried in the air or in drying rooms.

A particularly good one, any explosion and fire hazard during manufacture and in-use exclusive product is obtained at a ratio of about 14% chlorates (KC104 and K Cl 0g), 14J0 / 0% powdered gum arabic, io, 6% water, 8.3% coarse red phosphorus (P) or phosphorus sesquisulfide (P4 Ss) and 53% coarse Quartz flour (grinding i or 2). Instead of quartz flour can also use pumice flour and instead of gum arabic, water glass or 'lelm' as a binding agent with the addition of a small amount of rosin can be used.

The dry rattle discs are applied in such a way that they are rubbed on rough surfaces, whereupon they crackle loudly under the appearance of fire. There is no risk of fire or explosion because the mixed in Quartz or pumice forms partitions between the combustible parts, so that the Local fire phenomena on the smallest. Remaining limited to space and not to can encompass the entire disc. Manufacturing is for the same reason harmless after adding the quartz flour, as well as the residues on the manufacturing facilities stick, are not dangerous when dried. The volume of the Rattling when rubbing, however, is not influenced by this, but is the previous one Rattle washers and similar bodies completely equivalent.

Another advantage of this method is that heating the raw materials are no longer necessary in production. The invention is limited does not apply to the exemplary embodiment, but includes all fireworks which a close spatial separation of the chlorates and using quartz or pumice flour of phosphorus is to be achieved because of the risk of fire and explosion.

Claims (2)

PATENT CLAIMS: i. Process for preventing the risk of fire and explosion in the production of crackling stones, logs or similar fireworks, characterized in that the combustible, highly explosive phosphor particles are separated by adding quartz or pumice powder. 2. Exercise of the method according to claim i, characterized in that first the chlorates with powdered gum arabic dissolved in water and rubbed in until the mass is a homogeneous paste shows that coarse, powdery red phosphorus or Phosphorus sesquisulfide (P4 S ") is added until it is soaked through, and that you then immediately add quartz or pumice powder.
