Summary
Barium nitrate and antimony trisulfide are both poisonous. Gloves and respirator are a must when mixing (and should always be used anyway).
The author states that it is important to use the 809 American dark aluminum, as other types of dark aluminum will make the mixture too hot and cause it to behave like standard flash. The theory here is that droplets of a molten mixture are driven into the stars when the flash ignites, reducing the blind star problem often encountered when flash breaking shells.
