官窑八方水盂：拍品尺寸：直径：17.3cm，高：7.2cm，底径：12.5cm。此件官窑八方水盂，釉色莹沏，有蟹爪纹 ，紫口铁足；胎色较深，类铁，故而有铁胎（黑胎）之称。胎质致密、细腻、光滑。 本器物有“紫口铁足”的现象。器物的口沿做得比较尖，器足基本是刮釉垫烧。这样以来，口沿处的釉水就会自然往下走变稀变薄而呈现出胎骨的原色，足部自然也是露出胎骨色。 “南官”皆有纹（蟹爪纹），即开片，无纹者甚罕（传世整器中尚无发现），粗开片多以深黄、黄褐、墨色为多见，细开片呈灰白色，似冰开裂之纹，称做“冰裂纹”。---------------------------------------------Porcelain, Guanyao Eight party Water jar: Size: diameter: 17.3cm, height: 7.2cm, bottom diameter: 12.5cm.
