#402 #404 Pyrex Butterfly Gold bowls

Pyrex, a brand owned by Corning Inc., is renowned for its durable borosilicate glass cookware and bakeware. Introduced in 1915, Pyrex quickly became a staple in American kitchens due to its resistance to thermal shock and staining. The brand has produced numerous iconic patterns over the decades, many of which are now highly sought after by collectors.

The "Butterfly Gold" pattern was produced by Pyrex from 1972 to 1981. It features a delicate gold screen-printed design of stylized butterflies and flowers on a white or cream-colored milk glass base. This pattern was part of Pyrex's effort to offer more decorative options to consumers, moving beyond purely functional kitchenware.

The larger bowl has a tiny “blue” dot on it.
