Twinklers of the ammonium perchlorate base

Magnesium(60 mesh, coated with potassium bichromate) 

Ammonium perchlorate Strontium sulphate Calcium sulphate Sodium sulphate Barium sulphate 

These conpositions are manufactured into stars as follows One of the conpositions is kneaded by adding 25 parts of 10% nitrocellulose solution in acetone to 100 parts of the composition by weight and it is then cut into cubes, e. g., in 9 mm cubes by the method described in 14.2- 

The following nitrate base compositions were proposed by Y.Kinsei. The process of manufacturing the stars is almost the same as that of 

The same ignition composition described above can be used also for the nitrate base twinklers. In this case the potassium bichromate is unnecessary and the nitrocellulose paste should be used for the ignition coating with the ignition composition.
