Export China Appraisal

Mid-20th Century Chinese Export Porcelain with 'Zhongguo Zhizao' Mark

This item is a piece of Chinese export porcelain featuring a white glazed surface typical of 20th-century production. The most prominent feature is the iron-red stamped rectangular mark containing the four characters '中国制造' (Zhōngguó Zhìzào), which translates to 'Made in China.' This specific mark, written in simplified Chinese characters, indicates a production date likely from the late 1950s to the 1970s, as simplified characters became standardized in the People's Republic of China during this period. The porcelain body appears bright white with a smooth, reflective glaze, showing minor manufacturing artifacts such as small iron specks (pitting) common in high-fire ceramics. Attached next to the red stamp is a vintage adhesive paper label with handwritten inventory numbers or prices, which has yellowed and developed a brittle texture, suggesting it has been affixed for several decades. The application of the red stamp is slightly uneven, a common trait of mass-produced export wares from state-run factories of that era. There are no visible chips or cracks in the localized view, though the presence of some surface grime and minor staining near the markings suggests it has been handled throughout its history. The craftsmanship is consistent with functional export-grade porcelain of the mid-to-late 20th century.
