Anchor Hocking Cobalt Blue 1.5 Quart Rectangular Baking Dish

This is a rectangular baking dish made of heavy, molded borosilicate or tempered glass in a deep cobalt blue color. The item measures approximately 11 by 7 inches (28 x 18 cm) with a depth of about 1.5 to 2 inches, providing a 1.5-liter capacity. The bottom surface features a prominent textured or embossed maker's mark consisting of the Anchor Hocking logo—a stylized anchor within a square frame—along with the text 'Anchor Hocking Glass Company'. Supporting technical markings indicate it is 'CONVENTIONAL OVEN' and 'MICROWAVE SAFE'. The construction is robust with thick walls and rounded corners, characteristic of mid-to-late 20th-century American kitchenware. The condition appears to be very good with minimal visible surface scratching or 'flea bites' on the rim, though some minor manufacturing artifacts like cooling lines or faint striations in the glass are visible, which are common for this type of mass-produced glassware. The deep blue hue is uniform throughout the piece, showing high color saturation and clarity when held to the light. This specific style of 'Royal Blue' or cobalt kitchenware was highly popular in the 1990s and persists as a collectible functional item today.
