The use of copper-red on Yuan dynasty underglaze-decorated wares was unique in featuring largely reserve-decorated designs or decorated splashes. Cf. a stemcup decorated with splashes illustrated in Underglaze Blue & Red, col. pl. 29; two yuhuchunping, one decorated with splashes from the C. P. Lin Collection, the other with a reserve-decorated floral scroll on a brilliant red ground from the Percival David Foundation, were included in the Commemorative Exhibition, Elegant Form and Harmonious Decoration at the Percival David Foundation, 1992, Catalogue, nos. 16 and 17.
