Few glazes captivate the world of Chinese ceramics like Mirror Black. Originating during the Qing Dynasty’s K’ang Hsi period (1662–1722), this delicate black glaze earned its name for its deep, reflective quality, almost like polished glass. Mirror Black porcelain showcases subtle bluish or brownish reflections, a hallmark of its exquisite craftsmanship.

The glaze was achieved by mixing iron with cobaltiferous manganese ore, creating a unique depth and lustre. This glaze, sometimes referred to as Wu Chin or black gold, captures light in a way that lends each piece an almost magical shimmer. The delicate interplay of colours in the reflections—varying from dark coffee-brown to hints of blue—enhances the allure of each porcelain piece.

Mirror Black porcelain remains celebrated for its elegance and the technical skill required to achieve such a refined finish, making it a prized addition to collections of Chinese decorative arts. Each piece holds a touch of mystery and mastery, a true testament to the beauty and innovation of the K’ang Hsi artisans.
