ROCKET PROPELLANT #4
SOURCE: rec.pyrotechnics; Chris Beauregard.
COMMENTS: Also known as KNO3 propellant. The burn rate of this rocket's fuel depends much less on pressure than that of black powder. This widens the acceptable limits of the ratio of nozzle are/fuel surface area.
PREPARATION (parts by weight):
| CHEMICAL | PERCENT/PARTS | AMOUNT |
| Potassium nitrate | 0.720 | |
| Carbon | 0.240 | |
| Sulfur | 0.040 | |
