Casgliadau Arlein

Two joining fragments of blue-green window glass. Flaking iridescent surfaces. Cast into a shallow mould - two 'thumb' edges with a rounded corner between them extant. Tool impressions on upper surfaces, near corner, where glass has been pushed into corner of mould. Grained impression on underside, possibly left by wooden mould. Two of the broken edges have been chipped or grozed, forming a small rectangular pane.
