4.1. Experimental Method
Three types of bursting charge were prepared:
a) potassium perchlorate
b) black powder
c) potassium chlorate
The stars were made with potassium perchlorate as the oxidizer. Sample 5- and 6-inch chrysanthemum shells were prepared with these materials. The shells were reinforced by pasting them with Japanese or Kraft paper. The samples were ranked based on the number of paper layers.
