Zig Zag - Millersburg
Zig Zag has no pattern on the back, unusual for Millersburg. Found only in bowls in the usual range of Millersburg colors of amethyst, green, and marigold but several edge treatments can be found. Pictured above is a round three-in-one amethyst bowl and a squared crimped edge bowl. Other shapes include ice cream, round, ruffled and tricorner crimped.

Below are a tricorner bowl in a tremendous marigold courtesy of Seeck Auctions and an eight ruffled vaseline bowl courtesy of Wroda Auctions.
