This Cloisonne (hard enamel) lapel pin, can also be referred to as a hard enamel pin. It is created using the finest materials and workmanship. The Cloisonne lapel pin begins as a die struck pin, in which the shamrock is stamped using tons of pressure from a die. After the shamrock is struck out from the raw base metal it goes to coloring. The coloring process used starts with a powdered glass mixture which is then kiln-fired at over 1600 degrees this melts the glass-like powder into a hard solid color. The color is filled all the way to the surface of the depression made during die striking. After this the pin is individually buffed, giving it a high luster glossy finish that states quality and class.
