bead

Description
Green glass bead with yellow streaks. D-shape cross section. The University of Bradford undertook an X-ray Fluorescence analysis of the object in 1974 and provided the following information: "Green-Yellow quoit bead .... the bead is made of lead glass, and copper, iron and antimony seem to have been used as colorants. A small amount of tin was also detected; this may have been introduced as an impurity in one of the other metals. The form and composition of the bead made it unlikely to be of pre-Roman date".
In the museum's old register as "found near Roman fort, probably Rough Castle". It was assumed in later correspondence that it was found circa 1926.
