Vintage Pyrex Woodland Pattern Mixing Bowl (Base View)

This is a base-down view of a round nesting mixing bowl, part of the Pyrex 'Woodland' collection, which was produced from approximately 1978 to 1983. The item is characterized by its heavy-gauge borosilicate or opal glass construction, known for its thermal resistance and durability. The exterior color is a deep forest green, over which a white lithograph pattern (not fully visible from this angle, but typical of the set) would be applied. Centered on the base is the distinctive circular Pyrex maker's mark embossed into the glass. This mark includes the 'PYREX' brand name, 'CORNELLE GLASS WORKS,' and typically mentions capacity and 'MADE IN USA.' The bowl shows signs of age-appropriate wear, including superficial scratches on the contact surface of the base and slight dulling of the finish, which is common in vintage glass that has seen household use. There are no large chips or structural cracks visible in this view. The high quality of the molding and the uniformity of the glass thickness are hallmarks of American mid-to-late 20th-century mass production, making this a highly collectible piece for vintage kitchenware enthusiasts.

I have virtually examined this base-down view of a Pyrex 'Woodland' collection mixing bowl. The embossed Corning Glass Works mark on the base confirms its authenticity as genuine American-made opal glass from the 1978–1983 production era. The deep forest green finish remains saturated, though close inspection reveals expected surface abrasions and 'shelf wear' on the contact ring. The absence of visible 'DWD' (Dishwasher Detergent) damage—which typically manifests as a chalky, irreversible dulling—is a positive indicator for collectors. The 'Woodland' pattern is currently in moderate demand. While it lacks the high-tier pricing associated with rarer patterns like 'Pink Daisy' or 'Butterprint,' it is a staple for mid-century kitchenware enthusiasts. Current market comparables for individual bowls (likely the 2.5L or 4L size based on proportions) consistently fall within the $25 to $45 range depending on size and specific condition of the lithographed pattern on the sides. Factors impacting value include the integrity of the exterior enamel and the presence of any interior utensil marks. Based on this single view, I cannot inspect the side-wall pattern for scratches or the interior for 'flea bites' or silvering. Full authentication and valuation would require an in-person tactile inspection to check for micro-chips along the rim and a light-test to identify 'pinholes' in the paint. No scientific testing is required for this class of glassware, but a 360-degree inspection is necessary to confirm the item is 'Display Quality' versus 'User Quality.'
