Rising from a short circular hollow foot, the rounded sides tapering towards an inverted mouth, the interior and exterior undecorated and showing natural swirling natural inclusions in rich amber tone in imitation of realgar.

Provenance : Lillyman collection, California.

Note: Although somewhat simple in depiction, the current lot shows the extraordinary manner in which the glass-blowing has been controlled. Such vessels would have been crafted by blowing molten glass into a mould, forming the random and spontaneous swirling glass patterns. The colour is also manipulated to great effect, achieved by red and yellow glass merging to form a realgar-like effect.

Compare an almost identical yellow glass brushwasher from the Alan E. Feen Collection, illustrated in A Chorus of Colors, Asian Art Museum of San Francisco, 1995, pp.90-91, no.62, subsequently sold in these rooms, 24 November 2010, lot 205.
