Frederick Warren Studio Art Glass Tumbler showcases a mesmerizing blend of deep amethyst and iridescent fumed textures. This hand-blown vessel features a thick, weighted base with a polished pontil and unique applied glass "drips" or trailing accents that add sculptural dimension to the exterior. The lower half displays a complex, speckled iridescence with golden and blue tones, contrasting beautifully against the dark, glossy upper rim. Signed by the artist on the bottom, this piece serves as both a functional drinking glass and a striking work of decorative art.
