Description: | Fragment of cast copper alloy receptacle. "The Nanstallon brass is most likely to be 19th/20th century given the apparent lack of other impurities and the absence of tin, although this depends on the limits of detection in the analysis. It would not be impossible for it to be part of a Roman brass ingot but the few examples found and analysed have some lead in them. Another possibility would be 16th-17th century but I would expect some nickel and arsenic to be detected." (Dr. Peter Northover pers comm)
