This reprint of Volume III is the first to include the supplemental 300 pages of revisions and 250 additional woodcuts provided by John Jacob Holtzapffel in 1894, thus making available the complete text of this very rare book. Volume III covers in complete detail processes used to reduce and shape other than with cutting tools: the shaping and polishing of stone and marble; the grinding and sharpening of cutting tools to precise forms and angles; the producing of cylindrical, spherical, conical and plane surfaces by abrasion and surface grinding; glass cutting and etching, lens grinding and polishing; the use of diamonds in drilling and grinding; grinding of internal cylinders; lapidary work; gem and glass engraving; watchmaker s turning tools; varnishing, lacquering, and bronzing; and much more.
