I visited Lucie Rie A Retrospective in Chiba city museum yesterday.
At Lucie Rie A Retrospective, In her later day interview, Lucie Rie said she did not has "biscuit firing."
She just dried her pottery, glazed and dried it, then fired. So the glaze and clay have less fit. As a result, the glaze becomes thick and glassy.
Also, old Imari ware did not have "biscuit firing." So the glaze and clay fit less. The glaze becomes thick and glassy.
Lucie Rie is sometimes said to be oriental. I like her work very much.
