- W2003155410 abstract "The object of this short paper is to state a problem rather than to offer a solution. The traditional classification of prehistoric times into Stone, Bronze, and Iron Ages has proved to be insufficient. The word bronze, which denotes an alloy consisting principally of copper and tin, was used in a loose sense, and many objects, classed as bronze from their appearance only, have proved to be copper. Manyarcheeologists have therefore supposed that the Bronze Age was preceded by a Copper Age, sometimes regarded, as of great . duration. The introduction of bronze is then regarded as having been at first accidental, tin being added in varying proportions, until in course of . time experience showed that the composition of modern gun metal, approximately 90 per cent. copper and 10 per cent. tin, was the most generally useful. A case for this view could be made out by comparing the analyses of early metal implements from Asia, Egypt, and Europe. This view appeared most probable if it were assumed that copper was first used in the form of native metal, being hammered into shape without melting. Later the art of casting was discovered, but as pure copper can only be cast in an open mould, additions were made which increased the fluidity, and of these additions tin proved to be the most useful, so that in course of time tin bronze superseded copper and its alloys with arsenic or antimony. The metal tin was not, known until a comparatively late date, so that it must have been added in the form of the mineral cassiterite, or obtained in the course of smelting amixed ore of copper and tin. The first, metal known to man having been gold, found in the native and untarnished state in the beds of streams, it is natural to suppose that native copper would be the next metal to attract attention, although its appearance is less striking, andAs occurrence much less frequent, than that of gold. In North America, where native copper of very high purity occurs in enormous quantities in the neighbourhood of Lake Superior, the Indians became skilful in the working of the metal, and it has been possible to reconstruct their technique, using the simplest of means. 1 That native copper, although now" @default.
