Iron Age tankards are stave-built wooden vessels completely covered or bound in copper-alloy sheet. The distinctive copper-alloy handles of these vessels frequently display intricate ‘Celtic’ or La Tène art styles. They are characterised by their often highly original designs, complex manufacturing processes, and variety of find contexts. No systematic analysis of this artefact class has been undertaken since Corcoran’s (1952a) original study was published in Volume 18 of these Proceedings. New evidence from the Portable Antiquities Scheme for England and Wales and recent excavations have more than quadrupled the number of known examples (139 currently). It is therefore necessary and timely to re-examine tankards, and to reintegrate them into current debates surrounding material culture in later prehistory. Tankards originate in the later Iron Age and their use continued throughout much of the Roman period. As such, their design was subject to varying influences over time, both social and aesthetic. Their often highly individual form and decoration is testament to this fact and has created challenges in developing a workable typology (Corcoran 1952a; 1952b; 1957; Spratling 1972; Jackson 1990). A full examination of the decoration, construction, wear and repair, dating, and deposition contexts will allow for a reassessment of the role of tankards within the social and cultural milieu of later prehistoric and early Roman Britain.

<p>A highly active and selective hydrogenation of biomass-derived furfural into furfuryl alcohol was achieved using supported single phase Ni3Sn2 alloy catalysts. Various supports such as active carbon (AC), g-Al2O3, Al(OH)3, ZnO, TiO2, ZrO2, MgO, Li-TN, and SiO2 have been employed in order to understand the role of the support on the formation of Ni3Sn2 alloy phase and its catalytic performance. Supported Ni3Sn2 alloy catalysts were synthesised via a simple hydrothermal treatment of the mixture of aqueous solution of nickel chloride hexahydrate and ethanol solution of tin(II) chloride dihydrate in presence of ethylene glycol at 423 K for 24 h followed by H2 treatment at 673 K for 1.5 h, then characterised by using ICP-AES, XRD, H2- and N2-adsorption. XRD profiles of samples showed that the Ni3Sn2 alloy phases are readily formed during hydrothermal processes and become clearly observed at 2θ = 43-44o after H2 treatment. The presence of Ni3Sn2 alloy species that dispersed on the supports is believed to play a key role in highly active and selective hydrogenation of biomass-derived furfural towards furfuryl alcohol. Ni3Sn2 on TiO2 and ZnO supports exhibited much lower reaction temperature to achieved &gt;99% yield of furfuryl alcohol product compared with other supports. The effects of loading amount of Ni-Sn, reaction conditions (temperature and time profile) on the activity and selectivity towards the desired product are systematically discussed.
