Halinitro-Pyrobolia is a 1627 German treatise on gunpowder and fireworks by Joseph Furttenbach, printed in Germany for gunners and pyrotechnicians who needed practical instruction in refining saltpetre, sulphur and charcoal. Its copperplate figures show precise mechanical and scientific apparatus: a sealed vessel with tubes and fittings, a graduated balance with weights and dials, a cylindrical mortar on a stand, and a graduated arm with a pivoting pointer. A designer might draw on the crisp, measured technical drawing style, with ruled lettering and hatched shading, for diagrams of early machinery.
