How was enamelwork used on medieval religious objects such as chalices and reliquaries?

During the Middle Ages, enamelwork served as a primary decorative medium for ecclesiastical objects, including chalices, reliquaries, portable altars, and crosiers. These objects were often crafted from base metals like copper or bronze, which were then gilded and enriched with enamel to provide a durable, brilliant, and colorful finish.123

Key Techniques

• Champlevé: Flourishing in the 12th and 13th centuries, particularly within the Mosan school, this technique involved cutting troughs or cells into a metal plate and filling them with pulverized vitreous enamel. It became a hallmark of Romanesque metalwork, used extensively to decorate shrines and liturgical plate.435
• Basse-taille: Emerging in the late 13th century, this method involved intaglio relief carving in the metal surface, which was then filled with translucent enamel. This allowed for greater pictorial detail and was favored for its rich, glowing colors on gold and silver objects.36

These enamels were not merely decorative; they were integral to the symbolic and religious function of the objects, often adorning shrines designed to house the relics of saints, such as the Shrine of the Three Kings at Cologne.5
