The Identification Method of Porcelain from the Chenghua Period: 1. During the Chenghua era, porcelain pieces were characterized by their dignified and rounded shapes, elegant craftsmanship, and a wide variety of small-sized items. It is often said that "there are no large pieces in Chenghua," but this is not always strictly true. Some larger items do exist, though they are rare. 2. The porcelain body was made with pure, fine clay, resulting in thin and lightweight wares. When held up to light, the translucent body appeared either white or slightly pinkish, like fresh milk—smooth and soft to the touch. The glaze was thick, glossy, and smooth, with a fine texture and deep luster, giving it an overall refined appearance. 3. Chenghua blue-and-white porcelain is known for its subtle and quiet color palette. However, due to the thick application of cobalt pigment, the blue tones can appear lighter and sometimes hazy, as if covered by fog. This effect is most noticeable on the bottom of the piece. The blue colors tend to be heavier, similar to those seen in later Xuande period wares, while still maintaining a range of lighter shades. 4. Doucai (enamel underglaze painting) was a new technique developed during the Chenghua period. The decorative lines were delicate and slender, and the color was applied using a double-line filling method, with light and even coverage. There was no shading or detailed rendering, just flat coloring. Figures were painted in single-color coats without undergarments, leading to the saying “one coat†in reference to the kiln’s style. Chenghua blue-and-white is celebrated for its elegance and refined aesthetic. It replaced the earlier “Sui Mu Bo Qing†with the more stable “Equal Green Material,†producing a blue tone that has a greenish sheen, similar to the blue-and-white of the Hongzhi period. 5. The glaze on Chenghua porcelain had a very clear and bright finish, often described as “clearly see Chenghua, clearly see Yongzheng.†This clarity helps distinguish it from other periods. 6. The foot ring of Chenghua porcelain featured very neat and regular blue-and-white lines, especially near the base. The line was close to the foot, with a deeper color. This detail is one of the key characteristics used for identification. 7. The calligraphy on Chenghua porcelain was bold and powerful, resembling strong handwriting. The typical inscription was “Da Ming Cheng Huan Nian Zhi,†where the character “Da†(Great) had a rounded and high top, “Cheng†(Cheng) had a sharp waist, “Nian†(Year) had uneven sizes, and “Zhi†(of) was written without crossing strokes.
