Vintage Pyrex 4-Cup / 1-Quart Glass Measuring Cup

This is a vintage Pyrex glass measuring cup with a capacity of 4 cups (32 ounces / 1 quart). It is constructed from heavy-walled, high-quality heat-resistant glass, likely borosilicate or soda-lime glass depending on the specific manufacturing era. The vessel features a classic cylindrical shape with a integrated pouring spout and a large D-shaped handle that is open at the bottom for easy gripping. The measurement markings are applied in a vibrant red enamel print, featuring units for cups, ounces, and quarts on the exterior surface. Notable markings include the prominent 'PYREX' brand name in block letters with a registered trademark symbol. The font style suggests a mid-to-late 20th-century production, commonly associated with the 1970s or 1980s. Physically, the item appears in good used condition with minimal visible clouding or scratching common in heavily used kitchenware. The red lettering remains sharp and mostly intact, which is a key quality indicator as these markings often fade or wear off from machine washing over time. There are no immediate signs of chips on the rim or handle, and no significant structural cracks are visible in the heavy secondary shelving context. The thick glass walls demonstrate the durability and craftsmanship standard expected of the Corning Glass Works brand.
