Clear Glass Tea Cup or Tasting Bowl from IDL NY USA

This appears to be a clear glass tea cup or a small tasting bowl, designed with a thick and sturdy construction. The item is made entirely of transparent glass, exhibiting no coloration. Its form is circular, with a slightly flared rim that transitions into a gently curved, rounded body. The base is relatively thick and flat or slightly concave, providing stability. The overall aesthetic is minimalist and functional. There are no elaborate decorations, etchings, or applied patterns visible on the glass. The glass itself appears to be of good quality, with no significant bubbles, inclusions, or manufacturing flaws discernible from the provided images, suggesting a well-controlled production process. The surface is smooth and reflective, indicating a polished finish. In terms of condition, the glass shows some light surface scratches, particularly on the interior base and potentially on the exterior, consistent with regular use and cleaning. There are no visible chips, cracks, or repairs. The item is marked with 'No.3 idl ny USA' on the underside or possibly a side, which serves as a manufacturer's mark, indicating provenance from IDL (likely Industrial Design Labs or a similar entity) based in New York, USA. This marking suggests a modern manufacturing origin, likely from the mid-20th century onwards. The simple design points to a contemporary or mid-century modern style, emphasizing utility and clean lines. Its compact size and robust build suggest it is suitable for frequent use, possibly in a commercial or home setting for beverages like tea or small food tastings.
