Fabric: An iron-free (off-white to pink) clay with fine sand temper. Usually a clear lead glaze, but later examples have a copper-green glaze. Wheel-thrown, oxidized or reduced (difficult to tell because of the lack of iron). Knife-trimming is common.
Form: mainly spouted pitchers with plain strap handles and sagging bases.
