Northington Grange, Northington, Hampshire. Technical Examination of Glass from the Cupola
Author(s): David Dungworth
Four samples of glass from a cupola or dome previously installed at the top of a stair case at Northington Grange were examined. The glass is thick but curved; and smooth on one side but rough on the other side. The form of the glass suggests that it was cast and rolled then heated and bent over formers to achieve the desired shape. The glass is a soda-limesilica glass made using a synthetic or industrial form of soda. This suggests that the glass would probably have been manufactured after c1835. A slightly earlier manufacture cannot be entirely ruled out as there is insufficient data on the nature of early plate glass. The presence of arsenic (presumably used as a refining agent) is most consistent with manufacture prior to c1870.
