A two-piece dish is hen on nest covered dish. The design features a dish shaped like a nest and a lid in the shape of a hen. These dishes are often made of milk glass, which is an opaque white glass that was originally created to look like porcelain Originally, this style of dish was imported to the United States from England in the 1700s and was very expensive. It became more popular and widely available in the late 19th and early 20th centuries as American companies began mass-producing them. They were made by various glass companies, including Indiana Glass and Westmoreland Glass, and were used for a variety of purposes, such as holding candy, butter, trinkets, or as a decorative item.
