This book beautifully illustrates the wide range of artistic innovation and techniques expressed in vitreous, or "hard," enamels on metal. More than 30 experienced enamelists share their specialized knowledge for using cloisonne, plique-a-jour, champleve, and basse-taille techniques on silver, gold, foils, and metal clay to make jewelry, vessels, portraits, and more. Works from an additional 55 artists are also displayed in over 350 color photographs. Their words and work will instruct and inspire beginners and encourage the next generation of metal workers to carry enameling to new heights.
