Amber Footed Tumbler Appraisal

Libbey Amber Glass 'Prism' Pattern Footed Tumbler

This is a mid-century vintage footed drinking vessel, often referred to as a tumbler or water goblet, manufactured in a rich honey-toned amber pressed glass. The item features the 'Prism' pattern, characterized by a bold, geometric stack of faceted octagonal modules that create a heavy textured exterior. These deep-cut geometric shapes provide a prismatic effect when light passes through the thick glass. The vessel expands slightly from a narrow base toward a wide, smooth-rimmed mouth. It is supported by a short, integrated pedestal stem and a circular, slightly domed foot. Physically, the piece appears to be made of heavy-weight soda-lime glass, standing approximately 5 to 6 inches tall. The color is consistent throughout, showing deep golden and yellowish-brown hues typical of amberware from the 1960s and 1970s. Regarding condition, the glass retains a bright luster with no immediate visible cracks or large chips; however, there is typical shelf wear on the bottom of the base and some minor air bubbles (seeds) inherent in the pressing process. No maker's marks are visible on the base in this view, which is common for Libbey glassware of this era. The craftsmanship is robust and utilitarian, representing the mass-produced Mid-Century Modern aesthetic that prioritized geometric regularity.
