“…Mechanical alterations of archaeological metals were even conducted into the late 20th century, as evidenced by the restoration of a gold lozenge plate from Bush Barrow (Kinnes et al . 1988; Shell and Robinson 1988). One large difference between the earlier aggressive treatments and those conducted after the 1970s is that the more recent treatments are largely well documented and clearly identified.…”

“…The effects of other conservation treatments on stress relaxation require study, particularly some of the relatively aggressive approaches used earlier in the 20th century, such as 'superheated steam' cleaning, localized heat treatment using blow torches and high-temperature acid baths (Scott 2002).

Analysis of residual stress in archaeological copper alloy artefacts by neutron diffraction has considerable potential for the investigation of early fabrication processes. However, residual stresses in metals are known to relax due to conditions similar to those encountered during burial, corrosion and conservation. In this pilot study, we investigate the effects of corrosion and conservation on a small group of replica copper ingots. Although corrosion and light cleaning do indeed cause some relaxation of stresses in the metal, corrosion having the most significant effect, the basic patterns and major features of the stress profiles may still be seen.

“…Reconstruction in that case was arrived at by a different process, namely its actual restoration by an experienced metalwork conservator -Ian MacIntyre -who had observed that there was slack metal within the lozenge frame of the object which was inconsistent with an original planar object. It has been since been argued that the slack metal might be the result of postdepositional 'stretching' of the sheet (Shell & Robinson 1988) and this possibility must be borne in mind, but as for the Clandon piece there was no evidence for irregular stretching or any damage to decorative features. The result of the restoration was unexpected at the time, but it quickly became clear that the Bush Barrow lozenge made much more sense as a domed form once other fancy ornamental gear of the Early Bronze Age in Wessex and beyond was taken into consideration.…”

The famous assemblage of finery excavated by Edward Cunnington from Clandon Barrow, Dorset, in 1882 is usually held to be archetypal of the ‘Wessex culture’ and rich graves. Meticulous examination of the six artefacts and re-appraisal of comparative material casts a new light on the significance of the group. It does not represent a definable cultural package and instead points to a complex set of inter-relationships with ‘foreign’ lands achieved, above all, by plying varied maritime networks. Connections are shown to have run up the east coast of Britain, west towards the Irish Sea, and across the Channel to both Armorica and the Frisian coast. By contrast, links with inland Wessex were rather insubstantial. Questions are raised about the utility of the ‘Wessex’ label. Although uncertain whether it was a grave group or some other ritual deposit, the assemblage can be seen in a positive light as a record of great exploits in distant travel. The material assembled came to stand for the success of the south Dorset community and its key personages as judged against the prime concerns of Early Bronze Age society. Its paramount importance is emphasised by the choice of site – a focally positioned, yet relatively isolated barrow within a dense monumental landscape and, moreover, a barrow that saw recurrent rejuvenation as part of a cycle of remembrance.

“…Apart from its value for testing the shape of a deformed object through manipulation of a replica, the electrotype may alsoserve to preserve the distorted shape of an object that is to be reshaped. Shell & Robinson (1988: 2524 show how it has been possible to use an electrotype made in 1922 as the basis for a metrical analysis; this presumably utilizes the form of the lozenge that is nearest to its excavated state.…”
