Vintage Pyrex 1-Cup Clear Glass Measuring Cup

This is a classic 1-cup (8 oz / 250 ml) measuring cup manufactured by Pyrex, composed of thick, heavy-duty borosilicate or soda-lime tempered glass. The vessel features a cylindrical form that tapers slightly toward the base, an integrated pouring spout, and an arched D-shaped handle designed for ergonomic grip. The exterior is adorned with distinctive red baked-on enamel markings. The primary face displays '1 CUP' and '8 oz' graduation scales, with 'PYREX®' written vertically between them. Opposite this, a metric scale is visible. Based on the blocked lettering style and the positioning of the registered trademark symbol, this piece likely dates from the late 20th century, approximately the 1970s to the 1990s. The glass exhibits a high level of transparency, though there is visible 'dishwasher haze' or clouding and light mineral buildup at the bottom. The red lettering shows minor 'dishwasher fade' and slight abrasions, typical for a utilitarian kitchen item of this age. There are no large chips or structural cracks visible, though minor surface scratches are present from years of nesting and use. The thick-walled construction remains a hallmark of Pyrex craftsmanship, intended for thermal shock resistance.
