The Identification Method of Porcelain from the Hongzhi Period: 1. The porcelain body is similar in quality to that of the Chenghua period, with a fine and smooth texture. The clay used is well-prepared and evenly refined. 2. The glaze is thick, glossy, and has a soft, lustrous finish. It appears white and bright, though some pieces may show a slight grayish tinge. 3. The decorative lines are thin and flowing, appearing more delicate and transparent than when they were originally painted. This gives the artwork a softer, more ethereal look. 4. Many pieces exhibit a "bottom collapse" feature, where the base of the vessel is slightly indented or concave, while the inner rim is slightly raised. 5. The foot ring is smooth and rounded, with a shorter wall compared to Chenghua-style wares. The inner wall stands upright, and the depth varies depending on the piece. Official kiln bowls often resemble those of the Chenghua period, but they also display unique characteristics such as the "double-line design." 6. The color of the foot's glaze changes over time, starting from a pale white and gradually turning gray. Later pieces may have a bright green glaze, indicating different firing techniques or material compositions. 7. Although the script style follows traditional methods, the characters tend to be more refined and elegant. The strokes are slender and soft, giving the calligraphy a delicate appearance. The inscriptions are usually short, with four or six characters arranged in two lines, often written in a small and neat style. These features collectively help distinguish Hongzhi period porcelain from other periods, especially when compared to the earlier Chenghua era. Understanding these details can greatly assist collectors and enthusiasts in authenticating and appreciating these historical artifacts.
