A rare Russian spherical porcelain vase executed in the Art Nouveau style and decorated with a complex palette of flowing glazes. The surface is covered with vertical translucent streams of cobalt, purple, red and cream tones, creating a dynamic painterly effect and deep color layering. The wide mouth is accentuated by a contrasting cream glaze band with subtle crimson drips. The glaze pattern is executed with remarkable skill characteristic of the experimental series of the Imperial Porcelain Factory of the early twentieth century.
