Guangdong Porcelain Factory Ceramic Vessel

This item is the base of a Chinese ceramic vessel, most likely a vase or a ginger jar, featuring a distinct overglaze iron-red four-character mark. The mark reads 'Guangdong Ci Chang' (廣東磁廠), which translates directly to 'Guangdong Porcelain Factory.' This specific factory mark is typically associated with mid-to-late 20th-century production, particularly items exported from the Guangdong province during the 1950s through the 1970s. Physically, the piece is made of a white porcelain body with a clear glaze finish. The central recessed foot is glazed, highlighting the red stamp, while the foot rim is unglazed (biscuit porcelain) and shows significant brownish-yellow staining and surface grime, suggesting several decades of age or storage wear. Notable features include the square, double-bordered red seal mark which is characteristic of the export wares of that era. There are several visible condition issues, including irregular glaze thinning near the foot, scattered surface pitting (pinholes), and significant localized discoloration/organic staining around the unglazed rim and interior glaze surface. The craftsmanship represents a industrial-scale artisanal production, where hand-finishing is combined with standardized factory marking. The style is indicative of the 'Canton' style export porcelain revival seen in the late Republic to early People's Republic of China periods.
