Eastern long neck Spot-billed ducks in unglazed biscuit, using regional Shiwan potters "hair-incised" technique, perched on rocks with significant bubble bursts in a distinctive Shiwan monochrome white glaze, creatively imitating foaming beach water. Stamped "China" (the earliest export stamp) 1890 to 1919. Shiwan kilns, Foshan, Guangdong Province, Southern China. This pair of ducks show striking similarities to Huang Bing and Chen Weiyan styles and likely sculpted by next generation, succeeding students, or even family members who were Shiwan potters during Gaungxu/Republic Period.
