Its name implies a second part, and it is rumored that he wrote its manuscript before his death. It is also rumored that he was killed by members of the metallurgy/gunsmith/pyrotechnics guilds, who were opposed to him publishing a book about their secrets, and that they hid or destroyed the manuscript of the second part. Guilds aggressively protecting their production secrets was widespread in these times, as we can see from James Stirling having to flee Venice in 1725 for fear of being assassinated after finding out a trade secret of the glassmakers of Venice. Siemienowicz disparaged what he saw as a culture of secrecy based on "canting Alchymists of the times Pastโ€ฆthey dealed in nothing but Smoke, yet arrogantly took upon them to be Professors of so noble and excellent an art as Chymistry."

For over two centuries this work was used in Europe as a basic artillery manual / handbook. Its pyrotechnic formulations were used for over a century. The book provided the standard designs for creating rockets, fireballs, and other pyrotechnic devices.
