How to Identify High-Grade Porcelain:
1. Check the porcelain body quality: The body should be fine and porous, and when tapped, it should produce a clear, crisp sound. When purchasing antique porcelain, you must consider its age to determine the thickness of the body. For example, Nanding porcelain is usually thin-walled, while Beiding porcelain tends to be thicker. It’s recommended to carry a flashlight for better inspection. Instead of looking from the outside directly, take photos from the exterior and then examine the inside projection. If the shadow inside moves as you move your hand, it indicates the porcelain is thin.
2. Glaze color: The glaze should be even and accurate. After the Republic of China era, most porcelain had a white glaze, while Qing Dynasty porcelain often had a bluish or bean-blue tone. This is an important detail to remember when identifying antique pieces.
3. Painting style: The brushwork should be natural and smooth. When buying large porcelain items, make sure to differentiate between hand-painted and printed (decals) patterns. Decal patterns tend to look dull and lifeless, with rigid lines. For smaller blue-and-white porcelain, check the edges and corners — they may feel rough due to the glue used in decals. The edges of some porcelain may use decals, which can sometimes show seams or uneven patterns on either side.
4. Shape: The form should be unique and well-proportioned. Each piece should reflect the craftsmanship of its time.
How to Identify Low-Grade Large-Scale Porcelain:
1. Body quality: The body should be uniform without any collapses or irregularities.
2. Glaze and design: Learn to distinguish between hand-painted and decal techniques. Even if you're buying a decal piece, pay close attention to the quality of the print. Avoid cheap, poorly made decals that lack detail.
3. Shape: The mouth and base of the porcelain should be flat and even. Yang Kegui also advises Tibetan friends to purchase from trusted, established porcelain shops. These stores are less likely to deceive their regular customers, as they maintain a good reputation in the market.
