SENKO HANABI (JAPANESE SPARKLER) #1 (REALGAR-BASED)
SOURCE: Shimizu [1], page 70
COMMENTS: For more details on what the effect looks like and how devices can be constructed, look at §10.4, "The Phenomenon of Senko-Hanabi" in Shimizu's book (on page 68). Sulfur may be used instead of realgar (see next composition). This realgar-based formula produces larger and more beautiful sparks than the sulfur-based formula.
PREPARATION (parts by weight):
| CHEMICAL | PERCENT/PARTS | AMOUNT |
| Potassium nitrate | 0.350 | |
| Charcoal OR soot | 0.200 | |
| Realgar | 0.200 | |
