PRIMING COMPOSITION #5
SOURCE: Shimizu [1], page 218.
COMMENTS: A standard black powder priming cannot be used with stars that contain ammonium perchlorate, since a double decomposition reaction forms between the highly hygroscopic ammonium nitrate. This makes the stars non-ignitable. Replacing the potassium nitrate prime with this priming composition solves that problem.
PREPARATION (parts by weight):
| CHEMICAL | PERCENT/PARTS | AMOUNT |
| Sodium nitrate | 0.800 | |
| Paulownia coal | 0.150 | |
| Sulfur | 0.050 | |
