Fort Cumberland, Eastney, Portsmouth: An Investigation of Some Window Glass
Author(s): David Dungworth
The chemical analysis of fifteen fragments of window glass from Fort Cumberland was undertaken to identify the composition of glass used during the use of Casemate 54 and the repair of the Guardhouse (c 1940). The fragments of window glass from the Guardhouse all share the same composition and this compares well with reported values for glass manufactured in the middle of the 20th century. The fragments of window glass from Casemate 54 all share the same composition but this differs from reported 19th century glass. It is likely that all of the glass in casemate 54 was replaced in the later 20th century.
