Enameling applying refers to the technique of applying enamel, a glassy powdered coating, to a substrate—most commonly metal—before firing to fuse the coating to the surface. The result is a durable, colorful, glass-like finish used in jewelry, decorative arts, and some ceramics. Enamels are typically applied to copper, silver, or gold, with other metals such as brass or bronze also used. They can be applied as dry powders, wet slurries, or through brushwork and stenciling. Powdered enamel is sifted or dusted onto a clean, prepared surface, while slurry enamel is painted on as a suspension in water or another medium. Layering is common to build color, opacity, and texture.

Process and techniques: preparation starts with cleaning and degreasing the substrate to improve adhesion. A base layer may be applied when needed, followed by enamel in coats. Each layer is allowed to dry before the next application. The piece is then fired in a kiln or with a torch to fuse the enamel, at temperatures typically in the range of about 750–900°C (1,350–1,650°F), depending on the enamel type. After firing, the piece is cooled gradually. Additional layers may be fired in sequence to refine color and finish. Finishing steps can include grinding, polishing, or buffing to achieve a smooth, glossy surface.

Variations: techniques such as cloisonné or champlevé employ different methods of creating compartments or textures for enamel. Firing atmosphere, firing schedule, and enamel chemistry all influence the final appearance and durability.

Safety and handling: enamel powders can contain heavy metals; work in a well-ventilated area, use appropriate personal protective equipment, and follow manufacturer guidelines. Proper storage and cleanup reduce contamination and health risks.
