这件笔洗素面，内外没有任何纹饰装置，底有三托烧支钉，全器施满天青釉。釉色有深色亦有浅色覆盖器身。口沿处周边其色也褪变为浅灰色。笔洗中心有部份还是天青色，纹片在釉厚处，反映出冰裂纹，也是官汝窑特征之一。

This washer is plain with no ornaments on the internal and external surface. There are three small sesame spurs marks on the bottom. The washer fully covered with azure glaze. The glaze on the washer does not appear homogenous. The colour around the mouth rim fades to light grey. The density of the centre part glaze varies. The crackled on the thick glaze reflects a cracking ice-like visual effect, which is also one of the characteristics of Ru-guan ware.
