Casting Seams presents a collection of hand made ceramic plate multiples based on found 19th century Blue Willow plate shards. Repeatedly cast and re‐cast, the forms shed light on the matrix of positive and negative space in order to examine processes of reconstruction — that of the plates themselves and of the stories that are embedded within the found fragments. This site‐responsive exhibition takes place at and between two relational locations in Grey County: the South Grey Museum in Flesherton, and 8km away at the site where the shards were found on the former property of Edward Patterson, a nearly black settler, preacher, and stage coach driver believed to have been held in slavery in Maryland, U.S. From the earth to the museum context, the shards materially dialogue with private and public spaces — environments where meanings and materials are made and remade — reformulating old meanings with new objects 'in situ.’
