Nice to see you again Mr. Kleber.

 

From skylighter:

 

B12
Ammonium perchlorate	74.2
Copper dust	11.1
Stearin	11.1
Chlorowax	3.7
Dextrin	+5.0

H. Ellern's "Ashless Blue" #79 reprinted in Haarmann's "Pyrotechnic Formulary" and modified by the author by substituting chlorowax for paraffin and adding dextrin. Good ignition and burn rate. This ammonium perchlorate-only firework star composition was also the only pyrotechnic formula tested using elemental copper. Color saturation was good.
