官窑瓷多有纹片，有大小开片，亦称文武片。纹片有疏有密，有深有浅，以冰裂纹等大纹层为主，所谓“冰裂纹”者，如同冰糖、云母一般，层层而下，多角形的开片，显白色的纹路，由于机会不多，较为特殊。釉面出现的纹片原是一种缺陷，它由于制作过程中工艺处理不当，胎釉膨胀系数相差过大，使釉面发生裂纹，但我们的祖先巧妙地利用这种缺陷美，作为装饰瓷釉的特殊手段，使这种釉面纹路通过工艺的调整，控制裂纹的大小和疏密，形成纹片碎路，纵横交错，极不规则又在规则之中。
此拍品为“官窑青釉四方花觚”，口径：10.5cm高：22cm底径：8.54cm，整体器形端庄规整，线条挺建，撇口、弧腹，周身冰裂纹，底部附有崇宁五年款，紫口铁足特征明显。宋官窑瓷器存世量极少，当时烧造时间也非常短，收藏爱好者一生能得见一件亦是幸事，所以此件宋官窑瓷器具有极高的收藏价值和投资空间。

The official kiln porcelain has many patterns, and there are large and small pieces, also known as Wenwu tablets. The pattern is sparse and dense, deep and shallow, mainly composed of large cracks such as ice cracks. The so-called "ice cracks" are like rock sugar and mica. Layers are down, polygons are opened, and white lines are visible. Because there are not many opportunities, it is special. The glazed surface is a defect. Due to improper processing in the manufacturing process, the expansion coefficient of the glaze is too large, causing cracks in the glaze, but our ancestors skillfully used this defect as a decorative enamel. The special means to make this glazed grain through the adjustment of the process, control the size and density of the crack, form a broken road, criss-cross, extremely irregular and in the rules.
