Black Swirl Bowl Appraisal

Black and White Swirl Art Glass Bowl

This is a hand-blown art glass shallow bowl or centerpiece platter featuring a striking monochromatic swirl pattern. The design consists of alternating black and clear (translucent) glass canes spiraling outwards from a central point at the base to the outer edge, creating a dynamic visual pinwheel effect. The bowl has a wide, flared rim with a slightly irregular, undulating edge, which is characteristic of freeform hand-blown glass rather than machine-molded pieces. The material appears to be a heavy-weight sodium-calcium or lead crystal glass. In terms of condition, the glass retains a high gloss, though a price sticker is visible on the surface, which may leave adhesive residue upon removal. No significant chips, deep cracks, or clouding are immediateley apparent from the image focus. The style suggests a mid-to-late 20th-century influence, potentially inspired by Murano 'mezza filigrana' techniques or Scandinavian modernism. While no specific maker's mark is visible through the glass in this view, the quality of the spiral alignment indicates skilled craftsmanship. The base likely has a polished pontil mark indicative of its hand-finished production.
