Knot of a tree turned into a brush washer. It was lacquered in a dark color. This is a typical scholar's item. It must have been quite difficult to hollow out this heavy object as the wood is very dense and hard. The weight is also impressive at no less than 108 grams. The washer which looks like a fruit, dates from the 19th century but may possibly even be earlier. Height 4.8 cm. Diameter 6 cm.
