This paper considers cast iron within the context of commemoration using the author’s field data and also that from the archive on cast iron grave markers – CIGMs – created by the late amateur archaeologist (a professional pharmacist) Tony Yoward, assisted by his wife Mary, and now housed at the Ironbridge Museum Archives. Cast iron monuments could be made from one or more components, but most were single pieces and could be elaborately decorated or very plain. For most foundries, memorials were a minor sideline in their general ironwork business of gates and railings (as used for example at cemeteries), architectural fittings and agricultural tools, but there were some which produced memorials for a regional market, and some that were national. This paper examines cemetery products and reveals their diversity and significance.
