SENKO HANABI (JAPANESE SPARKLER) #2 (SULFUR-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). Realgar may be used instead of sulfur (see previous composition). The realgar-based formula produces larger and more beautiful sparks than this sulfur-based formula.
