Potter-Ballotini glassworks opened in 1956 (Potters Europe 2007 [accessed 16/1/08]) producing reflective glass beads for road signs. The current glassworks replaced the Oaks Glass and Bottle Works which was in operation between 1872 and 1927 and was owned by Sutcliffe, Wade and Dobson (Ashurst 1992, 126). This land was marked as unenclosed on Jefferys 1775 map. It was an area of surveyed enclosure that was part of the 1779 Barnsley enclosure award (date from English 1985). There is partial legibility of the surveyed enclosure pattern and the former glassworks site which was bounded by the route of the Dearne and Dove canal to the north and the curving parish boundary on the east.
