Lustreware (Zarrin-fam) vs Slip-painted ceramics

Lustreware (Zarrin-fam): A ceramic decoration in which metallic oxides are painted onto a glazed surface and fired in a reducing kiln to produce a metallic sheen, associated especially with Kashan. 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.
