Aboriginal uses for introduced glass, ceramic and flint from the former Schofields Aerodrome, Western Sydney (Darug Country), New South Wales

Since permanent colonial incursion in 1788, Aboriginal groups around Australia incorporated introduced materials for a variety of tasks. However, relatively little is known about Aboriginal uses of bottle glass and ceramic flakes because there have only been two published use-wear analyses concerning bottle glass and none for ceramic. Excavations at the historical site of the former Schofields Aerodrome in New South Wales yielded flakes of both materials as well as introduced flint. We draw on actualistic experiments to inform interpretations of use-wear among the 279 archaeological specimens. Results demonstrate that glass, ceramic and flint were indeed used at the former Schofields Aerodrome site, for tools to work other materials. This is the first evidence for such use of ceramic flakes, which had previously only been known to have been used as end-products, such as spear tips. Use-wear also indicates that, contrary to common assumptions, thicker parts of glass bottles were not always preferred for tools and that across each raw material, tools were predominantly shards rather than intentionally knapped flakes. We infer that while ascribing motives to past behaviours is complex, the use of the introduced materials represents agency in Aboriginal people’s engagement with the incoming colonial culture.
