Abstract: On the basis of a large number of published and unpublished analyses of Roman artifacts, the alloying traditions used in the production of a number of types or groups of objects are discussed. For each group, only a limited number of fairly well-defined alloys were used, probably depending on the manufacturing technique used, the color of the metal, and its mechanical properties. Three main types of bronze and two types of brass are identified. Leaded bronze was produced by addition of lead to a well-defined bronze and leaded gunmetal by mixing the leaded bronze with brass.

Abstract: Centuries before zinc was prepared in the metallic form, its ores were used for making brass and zinc compounds, were used for healing wounds and sore eyes Although the word brass frequently occurs in the Old Testament, there is little evidence that an alloy of zinc and copper was known in early times; the word translated brass might equally well be rendered bronze or copper, both of which were in common use.

Abstract: The techniques of metal colouring, bronzing and patination are assuming a new importance in contemporary fine metalwork and design. Richard Hughes and Michael Rowe have assembled and tested the recipes included in this book, which is the most comprehensive work on the subject currently available, an essential reference and sourcebook for practitioners and all those involvoved in sculpture, architecture, designs and the decorative arts. It brings together hundreds of recipes and treatments previously scattered in a variety of old books and technical papers, and provides the artist-craftsman with a very wide range of coloured finishes.
