①开裂(开片):釉与胎膨胀系数不匹配或冷却过快→换匹配釉、缓冷。②气泡:底釉未烧透/釉层含气/胎有油→充分烧底、薄涂、洁净胎。③脱落:胎脏或酸洗残留→重做预处理、水洗彻底。④色暗发雾:窑温不足或污染→提高温度、清洁窑具。⑤溢色(掐丝):填釉过满→控制厚度齐丝。

①Cracking (crazing): mismatch expansion or fast cool → matched enamel, slow cool. ②Bubbles: base not fused / gassy layer / oily base → fully fire base, thin coat, clean base. ③Flaking: dirty base or pickle residue → redo prep, rinse well. ④Dull/hazy: low temp or contamination → raise temp, clean shelves. ⑤Bleed (cloisonné): overfilled → keep level with wire. ---
