The Alkali-Metal Ratio in ROmano-British Bloomery Slags, Severn Estuary Levels, Southwest Britain, Values and Implications
John R L Allen
A further assessment of geochemical data previously reported on the composition of Romano-British bloomery slags from the Severn Estuary Levels (16 sites, 113 analyses) reveals that the Na2O/K2O ratio for furnace bottoms from non-tappable bowl furnaces in general is significantly higher than for the tap-slags from tappable devices. As sodium is the more volatile of the two metals, the difference in the ratio could indicate that the smelting process in the tappable furnace, most likely to have been of the shaft variety, was generally of a longer duration and/or at a higher temperature than in the simple bowl furnaces.

First Century AD Salt-Making at St. Georges, Worle, North Somerset Levels, Summary Report on Archaeological Investigations 2001-04
S. Cox
Neil Holbrook
Archaeological recording during construction work at St Georges, North Somerset, produced evidence of early Roman salt making. It is conceivable that production started on the site in the late Iron Age, but in the second half of the 1st century AD there was an intensification of activity using a new technology that required large ceramic pedestals to support the evaporation pans. Traces of one or more probable salterns were revealed. It is possible that the upsurge in salt production was in response to increased demand generated by the presence of the Roman army in south-west Britain. In the 2nd or 3rd century AD a series of drainage ditches was dug which may be associated with the transformation of the site into an embanked freshwater environment. The important collection of briquetage recovered from the site is discussed.

Forest Ports of the Severn
C G W Green
The coastline of the upper Severn Estuary, and particularly that of the Forest of Dean shore, has been populated by many places of maritime trade, large and small, for a long period. The following paper will seek to set in context the history of this area over time, together with a description of the development of the two main commercial ports of Lydney and Bullo, and with references to other small landing places. An important adjunct to the maritime trade was the construction of the ships used in that trade and a section deals with this, together with an appendix setting out the detailed list of ships built at four of the yards along the shore. Mention is also made of the importance of the ports to the Admiralty, with much of the timber for naval dockyards leaving from two ports in particular; Nelson was heavily involved in appraising the timber stocks of the Forest and is said to have been involved in negotiations with the Chepstow timber cartel to resolve a dispute in the early nineteenth century.
In Situ Preservation Research and Monitoring in the Somerset Levels, An Interim Report
L R Jones
A first interim report is presented on the rationale, methodology and initial fieldwork for a three-year research project examining in situ preservation at two sites in Somerset: Glastonbury Lake Village and the Sweet Track. This research focuses on chemical and hydrological change within the burial environment, in tandem with analysis of the sedimentary context. Since monitoring and laboratory analysis is at an early stage these aspects and interpretations will be discussed in subsequent interim reports.

Saxon Iron Smelting at Clearwell Quarry, St. Briavels, Lydney, Gloucestershire
J Pine
John R L Allen
Dana Challinor
An open area excavation carried out in advance of limestone extraction at Clearwell Quarry provides the first archaeological evidence for Saxon iron-smelting in the region. Of chief interest is the discovery of securely-dated Saxon iron-smelting features: thirty furnaces, both tap and slag-pit types; ten ore-roasting pits; and seven probable charcoal-clamps. Although datable finds were absent from these features, radiocarbon determinations on charcoal from three of the furnaces give consistent dates in the late 8th to 9th centuries. Chemical analysis of the slags showed them to be from the more inefficient end of the bloomery process in comparison to Roman slags from the same region. There was no evidence that blooms were being worked on the site after smelting. Mixed, but predominantly oak, charcoal was being used for fuel, and probably produced on the site. Other finds from the site included small quantities of prehistoric worked flint and medieval pottery: without the radiocarbon dates, there would have been nothing to suggest the furnaces were Saxon.
Geophysical Prospection of the Bronze Age Site at Caldicot, Monmouthershire
Carol Mansfield
The Bronze Age site at Caldicot, Monmouthshire was excavated from 1988-1992 during the creation of a recreational lake in the ground of the early 13th to the late 14th century castle (Nayling 1992; Nayling and Caseldine 1997). The excavations uncovered Bronze Age wooden structures, including one of the oldest sewn plank boats in Europe, within a series of intersecting palaeochannels of the River Nedern (Nayling 1992). This study revisits the site to conduct a geophysical survey over the area to the north of the original excavations. Its aim is to investigate the buried archaeology of the sedimented valley floor and the relationship of the archaeology to the palaeochannels and the dryland edge. A range of geophysical prospection techniques were used, including EMI (Electromagnetic Induction), GPR (Ground Penetrating Radar), ERT (Electro Resistivity Tomography) and magnetic gradiometry, along with a coring transect to ground truth the results. The high resistivity and high attenuation of the fine grained sediments within the sequence of intercutting palaeochannels are not ideal for geophysical surveys. However, the choice of low frequency (200MHz) GPR and EMI surveys allowed the EMI and GPR surveys to detect large landscape-scale feature. These included the interface between the alluvium and bedrock, palaeochannel features, and the potential continuation of a wooden post alignment found during the archaeological excavation.
