NoTE oN TREAsuRE AN<strong>AL</strong>ysEs<br />

Treasure analyses at the Department of Conservation<br />

and Scientific Research, British Museum, are carried<br />

out by Susan La Niece and Antony Simpson, using<br />

non-destructive x-ray fluorescence spectrometry (XRF).<br />

Treasure analyses at the Department of Archaeology<br />

& Numismatics, National Museum of Wales, are<br />

carried out by Mary Davis, using a scanning electron<br />

microscope with energy dispersive x-ray analysis (SEM<br />

EDX), with a low vacuum chamber where necessary.<br />

The surfaces of the objects are often corroded, even<br />

when not visibly so. The analysis is mainly of the<br />

surface and, whilst adequate in the majority of cases to<br />

establish for the purposes of the Treasure Act whether<br />

an object contains more than 10 per cent of precious<br />

metal, the percentages quoted are approximate and<br />

may not be an accurate analysis of the whole object.<br />

Gemstone identifications at the British Museum<br />

are undertaken by Janet Ambers, using a Raman<br />

microscope (Dilor LabRam equipped with a Nd:YAG<br />

green laser at 532nm and a near infrared diode laser<br />

at 785nm), and by standard gemmological techniques<br />

where appropriate.<br />
