A German-language mining handbook from 1853, published by Voigt, on the mechanical dressing of silver-bearing lead ores in the Upper Harz, written as a supplement to Karsten's metallurgy for mining students and engineers. Its pictures are mostly plates of ore-processing plant layouts, timber sluice and washing structures drawn in fine line, and a red wax seal, which together offer a designer clear technical diagrams and engraved-line textures to borrow.
