Post-medieval and modern glass is often collected from archaeological sites, or field walking.
Karen Adams has included assessments of Post-medieval and modern glass in a number of reports as archaeological contractor (PastSearch Archaeology) and for Community Projects, including Bishop’s Palace, Howden.
Assessments include detailed information for each shard (free blown, mould made, finishing types, date, etc) as well as photographs and in some cases illustrations.
Tables/gazetteers also included.
