Grueby is a type of pottery that originated in the United States during the late 19th century. It is known for its distinctive green glaze and simple, organic shapes. The pottery was produced by the Grueby Faience Company, founded by William Grueby in 1894, and became popular for its Arts and Crafts style, emphasizing craftsmanship and natural materials. The Grueby style often features decorative motifs inspired by nature, such as leaves and flowers. This pottery was part of a broader movement that sought to create functional art, and it played a significant role in the development of American ceramics during the Arts and Crafts period.
