An old capacity measure in copper, of the decalitre type, identifiable by the engraved plaque and visible markings on the body. The piece features a utilitarian and robust construction: copper body, riveted brass bands, iron side handles, and a cross-assembled bottom. The shape with a spout corresponds to the measuring instruments used in a professional context, for repeated and controlled use. The interior is tinned, still visible, indicating a use intended for liquids or goods, in accordance with the practices of the time. The inscriptions and markings attest to a regulated measuring object. The patina is old, marked by time and use, without recent cleaning or intervention. The visible traces are an integral part of the object and testify to its past function.
