Blue-and-white ceramics vs Slip-painted ceramics

Blue-and-white ceramics: Stonepaste wares painted in cobalt blue under a clear glaze, produced in Iran with strong dialogue with Chinese porcelain, especially in the Timurid and Safavid periods. Slip-painted ceramics: Earthenware decorated with coloured slips under a clear or tinted glaze, including early Islamic Nishapur-type wares and later village production such as Lalejin.
