哥窑作为宋代的五大名窑之一，至今窑址尚未确定，目前存在三种观点，即分别认为哥窑在龙泉、杭州或景德镇。哥窑瓷器以炉、瓶、洗、盘、碗等仿古式样为主，其最显著的特征是大开片中套小裂纹，即所谓“金丝铁线”。哥窑瓷器的釉属于无光釉，釉层极厚，有的地方厚到与胎的厚度相等的程度，使器物外观圆润饱满。胎体多为紫黑色、铁黑色或黄棕色，说明胎料中含有较多的铁质和其他金属杂质，因此也有“紫口铁足”的特征，与南宋官窑相似。

 
深圳万世艺术征集到珍稀藏品，经万世艺术资深专家边复初老师鉴定为【北宋哥窑洗】， 此北宋哥窑洗，口径：15.3cm，底径：11.3cm，高：5.5cm。器身焕发犹如“酥油”般的光泽，哥窑洗内外布满疏密有致的自然网状开片纹，较粗琉的黑色裂纹交织着。明代《格古要论》中有这样的描述：“哥窑纹取冰裂、鳝血为上，梅花片墨纹次之。细碎纹，纹之下也。”哥窑器坯体大都是紫黑色或棕黄色，器皿口部口边缘釉薄处由于隐纹露出胎色而呈黄褐色，同时在底足未挂釉处呈现铁黑色，由此，可以概括出故有“紫口铁足”之说。经专家鉴定，此北宋哥窑洗，从釉色，品相，包浆，胎骨等各方面综合看，是难得的哥窑精品。
