Crucibles were used for melting glass or metals, such as gold, and pouring the melted material into molds. This stoneware crucible was made by the Battersea Works of England. The works was opened in the 1850s by the Morgan brothers and continued to operate until 1956. This particular piece dates prior to 1881, when the company changed its name to the Morgan Crucible Company. It was recovered in the backyard of 40 Natoma Street. Although most crucibles are made of strong clay, iron crucibles like the one here were also used. This sample was recovered within the former Risdon Iron Works.
