Mid-Century Modern Triangular Studio Pottery Vase

This is a tall, three-sided (triangular) studio pottery vase or vessel, likely dating from the mid-to-late 20th century. The piece is constructed with sharp geomtric lines, featuring three flat vertical faces that meet at slightly rounded corners. It is finished in a high-gloss lead or alkaline glaze showing a rich 'tiger-eye' or 'dripped' effect. The primary colors consist of a deep chocolate brown that flows and bleeds into a caramel or mustard-yellow base, creating organic, vertical drip patterns that contrast with the rigid geometric form. The neck is finished with a short, flared, circular collar in a contrasting light-colored clay or glaze, suggesting a hand-thrown attachment to a slab-built body. The piece appears to be in good vintage condition with no visible cracks or large chips in the image, though some minor kiln stilt marks or base wear may be present. The craftsmanship reflects a professional studio pottery origin, common in the 1960s-1970s Brutalist or Modernist movements. No specific maker's mark is visible from this angle, but the glaze technique is reminiscent of North American or Scandinavian studio work.
