Human beings have been using metals since the bronze age because of their unique optical, mechanical and physical properties, which originate from itinerant electrons. In this article, we introduce basic models to describe itinerant electrons in metals. We also introduce optical spectroscopy techniques and spectrum analysis methods that can be used to study the optical properties of metals. We hope that our article will be helpful for researchers using optical spectroscopy techniques in the field of metals and anyone who is interested in the optical properties of metals.

Summary Two small burnt mounds were excavated as part of the programme to mitigate the impact of motorway construction in the Crawford area. The excavations followed a research strategy designed to address questions of date and function. This paper surveys the various competing theories about burnt mounds and how the archaeological evidence was evaluated against those theories. Both sites produced radiocarbon dates from the Bronze Age and evidence to suggest that they were cooking places. In addition, a short account is presented of two further burnt mounds discovered during the construction of the motorway in Annandale.

Summary A programme of archaeological work was undertaken by Glasgow University Archaeological Research Division (GUARD) at West Flank Road, Drumchapel, in close proximity to the site of the prehistoric cemetery of Knappers. This paper considers the results of excavation of a range of negative features, including earlier Neolithic and Bronze Age pits and postholes. The earlier Neolithic features date to c. 3500–3000 BC and are interpreted as the partial remains of a subrectangular structure. The Bronze Age features may relate to ceremonial activities in the wider area. The significance of these remains is considered in relation to the site of Knappers and wider traditions during the fourth to second millennia BC.
