This item is a vintage Pyrex Cinderella mixing bowl featuring the 'Autumn Harvest' pattern, which was produced by Corning Glass Works between 1979 and 1986. The bowl is constructed from opal white borosilicate glass with a fired-on exterior color scheme. It exhibits a distinctive horizontal gradient of warm tones, transitioning from a dark mahogany brown at the rim to a lighter burnt orange or amber hue towards the base. The 'Cinderella' style is defined by its dual-purpose handles: one large pouring spout and one smaller handle, which facilitate easy handling and pouring. The central decorative motif consists of a screen-printed line drawing of wheat stalks and various fruits, including grapes and apples, rendered in high-contrast brown ink. Physiically, the bowl appears to be around 1.5 to 2.5 quarts in capacity. Regarding condition, there is visible 'DWD' (dishwashing detergent) damage typical of this era, manifesting as a loss of original high-gloss shine and a dull, matte chalkiness to the finish. Fine surface scratches and small nicks in the paint are visible upon close inspection, particularly near the rim and along the sides, though the glass itself appears structurally sound with no major chips or cracks visible in the provided image. The interior remains white, albeit likely with some metal utensil marks from use. Such pieces are signature examples of Americana kitchenware from the late 20th century.

I have examined the digital representation of the Pyrex 'Autumn Harvest' Cinderella mixing bowl. Authenticity is confirmed by the distinct pattern morphology and the classic Cinderella form produced by Corning Glass Works between 1979 and 1986. While the 'Autumn Harvest' pattern remains a beloved staple of late 20th-century Americana, market value is heavily dictated by the physical state of the fired-on finish. Upon visual inspection, the item exhibits significant 'DWD' (Dishwasher Detergent) damage. The original high-gloss luster has been stripped, resulting in a dull, chalky surface. This permanent etching of the glass negatively impacts the item's aesthetic and tactile appeal. Additionally, visible scratches and minor paint loss further categorize this as a 'utility' piece rather than a 'collector' grade specimen. In the current secondary market, such as online auctions and antique malls, high-gloss examples of this specific size (likely the 1.5-quart #442) command $25–$35. The loss of shine on this piece reduces its value by approximately 50-60%. Limitations of this digital appraisal include the inability to verify the severity of interior utensil marks or detect micro-fissures in the glass. A full authentication would require an in-person tactile inspection to check for hidden chips under the handles and a light-box test to assess pattern consistency. Provenance documentation is rarely available for mass-produced kitchenware and is not required for valuation here, but a physical examination remains the only way to definitively rule out structural compromises not visible in the image.
