Opalescent glass butter dish with dome cover in the Iris with Meander pattern

This butter dish represents American pressed glass from the late Victorian era, specifically the Early American Pattern Glass (EAPG) period of the 1890s-1900s. The Iris with Meander pattern was produced by several glass manufacturers during this time, featuring naturalistic iris flowers and flowing vine designs that were popular in Art Nouveau decorative arts. The opalescent finish, which creates a milky blue-white glow at the edges, was achieved through special heat treatment and was highly prized during this period. Opalescent EAPG pieces like this butter dish are highly sought after by collectors of American pressed glass and Victorian-era tableware. These items appeal to antique glass enthusiasts who appreciate the craftsmanship of hand-pressed molds and the delicate opalescent effect that requires specific firing techniques. The butter dish format makes it both a collectible and a functional piece of decorative art, valued for its historical significance as an example of American glass manufacturing innovation and the aesthetic sensibilities of the Gilded Age.
