VIII, 313 p. With 26 wood engravings. 17 x 11 cm. Semi - leather d. C. (something rubbed and toasted) with gold-embossed shield. Frankfurt, C. Jügel, 1853. Baldamus, Gewerbskunde p. 53 (2nd ed. First German edition of "The Manufacture of steel" (Philadelphia, 1851). In his preface, the well-known mining and iron and steel engineer Hartmann (1796-1863) emphasized the growing importance of steel production and pointed out that an understandable and "well-being" German-language work on the subject had not yet appeared. The work on Overman's current plant is intended to fill this gap by addressing all aspects of steel production and processing. Overman (ca. 1803-1852) was born in Cologne and was considered an expert in metallurgy in the USA. Most of his works "were published at a time when it was difficult to maintain scientific information on such subjects, and they were accepted as authority and passed through several editions".
