The Anchor Hocking "Swirl Golden Anniversary" pattern is a vintage line of white milk glass dinnerware featuring a distinctive 22-karat gold trim, produced primarily in the 1950s. It is a popular collectible from the mid-century era and is part of the broader Fire-King brand of ovenware. The gold trim often has an irregular or "spattered" effect on the inside edge, which was part of the original manufacturing process.
