Vintage Anchor Hocking Fire-King Glass Measuring Cup

This is a vintage one-cup capacity liquid measuring cup manufactured by Anchor Hocking under the Fire-King brand. The item is constructed from thick, clear tempered borosilicate or sodalime glass, designed for heat resistance and durability in a domestic kitchen setting. It features a molded spout for easy pouring and an integrated glass handle. The interior side walls display embossed graduations showing measurements in ounces (8 oz, 6 oz, 4 oz) and fractions of a cup (1 cup, 3/4, 1/2, 1/4). A primary distinguishing feature is the embossed maker's mark on the bottom exterior, which consists of the classic Anchor Hocking 'anchor over H' logo, surrounded by arched text reading 'FIRE-KING' and 'MADE IN U.S.A.' along with 'OVEN-PROOF'. The glass has a slight greenish-blue tint characteristic of mid-20th-century American glassware. In terms of condition, the glass appears relatively clear with some surface scratches and minor clouding (scuffing) consistent with age and frequent use. There are no large chips or structural cracks visible from the top-down perspective, though heavy use typically results in small 'flea bites' around the rim or base. Based on the specific logo design, this piece likely dates from the 1940s to the 1970s, representing a staple of mid-century American kitchenware.
