Glazed vessels prepared first by incising decorations into their surfaces, and then by the addition of paint into these incisions prior to the application of glaze. The result is a fine contrast between the decoration, which is usually bright in colour, and the overall tone of the glazed vessel. Byzantine sgraffito wares dating to the 11th and 12th centuries are some of the earliest known from western Europe, but the technique failed to take hold in North European pottery until the end of the Middle Ages and was only established in the 16th and 17th centuries.
