Large celadon pottery dish, possibly by Ontario studio potter Harlan House (based on glaze, shape). Celadon changing to almost rose colour at rim (see photo 10 for detail). Marked with incised HH (see photo 4). Also marked with name "McCantry"? which may be name of person for who this piece was made. Not typical style of HH mark but fact that it is marked with HH and has celadon glaze indicates that it is by Harlan House. Anyway that is my opinion. Diameter 13 5/8 inches (34.7 cm) Height 4.0 inches (10.1 cm). No chips, cracks or other damage. A couple of points where the glaze bubbled when the piece was fired (see photo 10).
