About This Book

A combined manual of goldsmithing and sculpture lays out practical, workshop-focused instructions and recipes for metalworking processes, including niello, filigree, enamelling, gem setting, diamond cutting and tinting, gilding, etching, medal making, various casting methods for vessels and large bronze figures, and furnace construction. Chapters present step-by-step procedures, material preparations, tool use, and formulas for chemical treatments and colours. Technical anecdotes and illustrative examples appear throughout, conveying common workshop problems and their solutions in an informal, spoken-register voice. The work functions as both a craftsman's handbook and a record of traditional techniques and workshop practice.
