Pyrotechny : $b or, The art of making fireworks, at little cost, and with complete safety and cleanliness.

"Pyrotechny: or, The Art of Making Fireworks, at Little Cost, and with Complete Safety and Cleanliness" by Practicus is a scientific manual written in the mid to late 19th century. The book is focused on providing practical, accessible instructions for amateur pyrotechnists who wish to create fireworks displays safely, cleanly, and economically, with a strong emphasis on detailed technique rather than professional secrets or historical background. It is richly illustrated and covers a comprehensive range of firework types, tools, and materials, aiming to demystify the subject for hobbyists and enthusiasts. The opening of this manual introduces the reader to the recent developments and safety improvements in the art of firework making, contrasting its modern methods with outdated, hazardous traditions. Practicus outlines the lack of accessible English-language guides, setting the stage for his practical, step-by-step approach. He addresses common concerns about danger, dirt, and expense, asserting that these can be mitigated with care and proper method. The text then proceeds to cover essential tools (scales, weights, pestle, mortar, sieves), economical approaches, and initial hands-on processes like making rocket cases, preparing compositions, and assembling basic rocket components, all with meticulous instruction and practical advice designed for the beginner.
