Highland House, 117 Lidiard Gardens, Portsmouth: Chemical Analysis of Window Glass
Author(s): David Dungworth, Roger Wilkes
The chemical analysis of thirteen fragments of window glass from Highland House was undertaken in an attempt to identify the composition of the glass originally installed during its construction in the 1880s. Two fragments have compositions which are similar to previously analysed late 19th-century glass. The remaining samples have compositions which suggest they are later replacements. The magnesium concentration of these later samples is considered and evidence for dividing them into an early group (1930–1960) with <3wt% MgO and a later group (1960+) with 3.5–4.1wt% MgO is discussed.
