A burnisher is an artist’s tool, used for rubbing and polishing gold leaf on vellum. It consists of a head or rubbing surface, made of polished ivory or hematite, mounted on a wooden handle. It is a period artifact: its construction, in this form, is described in Cennini’s Libro dell’Arte, 1437. However, it doesn’t appear to have been used in armory. The burnishing head is to chief by Society default.
