The brown colour of the tortoiseshell ware is derived from
manganese oxide. The different clouded effects were obtained by treating the
lead glaze with different oxides; only that with brown mottling is properly
called "tortoiseshell," though the term is often used loosely to
include multicoloured clouded ware in general.
