High temperature class compositions which contain ammonium perchlorate

Igniter B Sodium nitrate Paulovmia coal Sulphur 

This is a kind of B -black blasting powder which contains sodium nitrate in place of potassium nitrate and does not cause such a reaction with ammonium perchlorate as described above. 

This is obtained from the above formula of Ammon red star brilliant replacing strontium carbonate with ultramarine, NajSa.3NaAlSi04 ( ). Specific gravity=1.08 g/cc Burning rate =5.5 mm/sec 

This is obtained also from the formula of Ammon red star brilliant replacing strontium carbonate with barium carbonate. 

These compositions are used for special artistic effect. The shells which contain these stars are not necessary to be of moistureproof construction.
