Set 4 Pyrex Glass Nesting Bowls

A set of four nesting mixing bowls crafted from opaque tempered glass with a fired-on color finish. The set features an alternating color palette of medium sapphire blue and light turquoise blue. The bowls are designed with a wide, flat rim and a circular clear glass base that reveals the transparent body of the vessel beneath the exterior pigment. The largest bowl, finished in sapphire blue, features an embossed mark on the underside of the base arranged in a circular format. The mark includes the following readable characters: PYREX, BAKEWARE, 250, FOR OVEN AND MICROWAVE, and CORNING NY USA. The light turquoise blue bowl also bears an embossed mark on the base featuring PYREX and CORNING NY. The smaller sapphire and turquoise bowls exhibit similar circular embossed markings with a central concentric ring pattern, though the finer alphanumeric details on these smaller examples are less distinct.
