1940s Vintage Pyrex Refrigerator Dish — Primary Blue 502 — MCM Bakeware USA

Vintage 1940s Pyrex Primary Blue 502 refrigerator dish — one of the four original "Primary Colors" Pyrex pieces and a cornerstone of American mid-century kitchenware collecting. Professionally packed for fragile shipment. Ships next business day. Full refund if damaged in transit.

The Primary Colors series is among the most recognizable Pyrex patterns produced, featuring solid cobalt blue, red, green, and yellow pieces designed specifically for refrigerator storage. The model 502 is a rectangular covered dish in the smaller size of the series, built for efficient Depression- and wartime-era refrigerator organization. This example is the dish only — no lid — and is priced accordingly.

The cobalt blue color is deep and fully saturated with no cloudiness, fading, or interior staining. No chips, cracks, or crazing to the glass. Exterior shows typical light shelf marks consistent with age and use. The Pyrex backstamp on the base is legible. A strong standalone display piece or a functional addition to an active Pyrex collection.
