Material Genealogies:Bronze Moulds and their Castings in Later Bronze Age Britain

Bivalve bronze moulds were used for casting bronze and lead objects – mainly axes – during the Middle and Late Bronze Age. These remarkable artefacts, which were sometimes beautifully decorated, have been surprisingly little studied. This paper discusses the bronze moulds from Britain, outlining the range of possibilities that existed for the life courses of these objects during the three broad stages of manufacture, use, and deposition. Two points will be emphasised. First, it will be shown that the biographical pathways available to bronze moulds differed significantly from those of moulds made from stone or clay, which may relate to the differing properties and conceptual associations of these three materials. Secondly, the relationships between the life courses of bronze moulds and the artefacts cast in them will be explored, focusing particularly on cases in which moulds and their castings were deposited together in the same hoard. It will be suggested that the ‘genealogical’ link between a mould and its ‘offspring’ could have formed a significant element of the biography of both objects

Emerging CO2 capture systems

In 2005, the IPCC SRCCS recognized the large potential for developing and scaling up a wide range of emerging CO2 capture technologies that promised to deliver lower energy penalties and cost. These included new energy conversion technologies such as chemical looping and novel capture systems based on the use of solid sorbents or membrane-based separation systems. In the last 10 years, a substantial body of scientific and technical literature on these topics has been produced from a large number of R&D projects worldwide, trying to demonstrate these concepts at increasing pilot scales, test and model the performance of key components at bench scale, investigate and develop improved functional materials, optimize the full process schemes with a view to a wide range of industrial applications, and to carry out more rigorous cost studies etc. This paper presents a general and critical review of the state of the art of these emerging CO2 capture technologies paying special attention to specific process routes that have undergone a substantial increase in technical readiness level toward the large scales required by any CO2 capture system

Excavations at Langtoft, Lincolnshire, Areas B to E

Areas B-E of Baston (No. 2) Quarry, Langtoft, Lincolnshire, were excavated in stages between 2001 and 2003 by the Cambridge Archaeological Unit (CAU). These areas together form a contiguous, L-shaped swathe of 7.3ha (fig. 2), immediately to the south of the previously investigated Area A. The fieldwork was carried out on behalf of Hanson Aggregates Plc in advance of gravel extraction. The excavation results presented in this report will be incorporated into the forthcoming publication of all CAU investigations in the Langtoft area. This publication will more fully discuss the wider context and significance of the later prehistoric settlement and salt-making in Areas B-E

Middle Bronze Age Finds at Langtoft Common, Lincolnshire. Am Archaeological Watching Brief.

An archaeological watching brief was carried out on behalf of Hanson Aggregates Pic on land off Cross Road, Langtoft, Lincolnshire (centred TF 147/137) between 27th April and 26th May 2001. A total area of c. 250m east–west by 50m north–south was stripped under archaeological supervision in advance of gravel quarrying. The results of the watching brief are fully presented in this report, and will be set into their wider context by the forthcoming publication of all CAU investigations at Langtoft

The Bell School, Cambridge: An Archaeological Desktop Assessment

This report has been commissioned by the Bell Educational Trust in advance of a planning application for land off Babraham Road, Cambridge (centred TL 4675 5485). It follows on from an earlier desktop assessment which examined the archaeology of the wider area (Evans 2002), including an analysis of the aerial photographic evidence. The known and potential archaeology of the proposed development zone (the Study Area ) will be assessed here, drawing on evidence from an area stretching for 700m in each direction from its boundaries (the Environs)

Bridge Farm, Earith, Cambridgeshire. An Archaeological Desk-Based Assessment

This desktop assessment has been commissioned by in advance of a planning application for gravel quarrying. The purpose of the report is to collate and summarise the known and potential archaeology of the proposed development area and its environs, and to assess the likely character, quality and preservation of the archaeological remains within the development area itself
