Enamelwork
Standing dish depicting Samson crushing the Philistines with the jawbone of an ass, enamel on copper by Pierre Courteys, c. 1580; in the Taft Museum of Art, Cincinnati, Ohio. Height 9.8 cm, diameter 22.9 cm.
The firing process for enamelwork is relatively quick, typically taking only a few minutes to complete.1
Once the powdered enamel has been applied to the prepared metal surface and dried in front of the furnace, the object is placed into the muffle—a protected compartment within the furnace. It is heated until the enamel reaches the point of fusion, allowing it to adhere to the metal base, after which the piece is removed and allowed to cool.1
