清 豆青釉花卉筆洗 Qing Dynasty period. Of compressed circular form, the side moulded with floral decorations in shallow relief, the exterior suffused overall with attractive sea green tone, all supported on four shallow feet, base with a raised four character mark. 豆青釉，青釉派生釉色之一，起源於宋代的龍泉窯。豆青和東青原屬一類，以後才各具特色。明以前微近黃色，至清純近綠色。其釉色為青中泛黃，釉面光澤比粉青、梅子青弱。此件筆洗造型規整，發色自然，刻花工藝細膩精湛，為不可多得精品。
