Application of Kernel Density Estimates to Lead Isotope Compositions of Bronzes from Ningxia,North‐West China

The aim of this paper is to apply kernel density estimates (KDEs) to the visualization and interpretation of lead isotope data from bronze assemblages found along the northern border of central China, here designated as the Arc. New lead isotope analyses of 30 leaded tin–bronze artefacts from the Wangdahu cemetery (c.500–300 bc ) in the Ningxia Hui Autonomous Region, north‐west China, provide the basis for the discussion. By using multivariate KDEs and the calculated likelihood of the overlap, the present work shows that the Wangdahu objects feature a unique linear array of isotope ratios, representing an important element of overall bronzes from the Arc in the first millennium bc . This characteristic isotope signature is fundamentally different from that of Dajing ores in north‐east China, as well from that of early Qin bronzes in Shaanxi and Gansu provinces. This suggests that a variety of metal resources were utilized by peoples living in the Arc. The KDE approach thus proves effective at presenting and comparing lead isotope data.     

Swedish wage policy and Australia three years after Australia reconstructed

During the 1980s, and with increasing speed, there have been major changes in the determination of wages in Sweden; changes which involve the substantial breakdown of the ‘Swedish model’ of social and economic policy which had developed since the 1930s. These changes are of much interest in themselves but have a special relevance to Australia because of admiration for the Swedish system within the Australian labour movement, exemplified by the major report Australia Reconstructed, published in 1987. Some of the complexities and difficulties involved in the Swedish system were not fully dealt with in this report, while others have become clear since its publication. Australians, as well as others, need to appreciate what has occurred. Centralised wage negotiation, essential to the Swedish model, has in fact survived better in Australia than in Sweden; though in Australia too it is potentially vulnerable to tendencies towards decentralisation. Those interested in the concept of ‘corporatism’ should also note these developments, Sweden having been thought of as a highly ‘corporatist’ polity.     

From Alloy Composition to Alloying Practice: Chinese Bronzes

We propose a new methodology based on standard statistical processes for displaying and rigorously comparing the alloy composition of archaeological bronze alloys. Although traditional approaches using visual comparisons of histograms of alloying elements in an assemblage of archaeological objects are adequate for observing differences between these distributions, we argue that differences in sample size cannot be adequately accounted for without using a statistical approach. We demonstrate this methodology by comparing the alloy composition of bronzes from the sequence of Bronze Age cultures in Central China—Erlitou, Erligang (Zhengzhou, or early Shang), Anyang (late Shang) and Western Zhou. We suggest that this approach allows the identification and rigorous comparison of ‘regional alloying practices’, which in turn enables us to link the alloy composition of the objects with the intentions and skills of foundry workers.

Some Recently Rediscovered Analyses of Chinese Bronzes from Oxford

We report here the rediscovery of the chemical analyses of approximately 540 Chinese bronze objects, carried out in RLAHA in the late 1950s by optical emission spectrometry. Although largely of historical interest, they do in fact even now approximately double the number analyses of Chinese bronze objects that contain data on both major and minor elements. In fact, the other major equivalent data sets, from the Freer Gallery and the Sackler Collection, are of approximately the same vintage. We attempt to evaluate the quality of the data, and address a controversy that appeared in the literature during the 1960s and 1970s about the value of arsenic measurements in Chinese bronzes as an indicator of authenticity.
