“Painting, created on a copper plate, covered with enamel and melted in fire, exceeds sculpture in durability. If a bronze sculpture is highly durable, an enamel painting is everlasting.” These words belong to the great Leonardo da Vinci and may be proudly cited by probably any artist that works with the technique of vitreous enamel. Frankly luxurious, almost obscenely expensive even during the stage of preparation, colorful and iridescent, tridimensional and unpredictable… Enamel is not simply universal but also surprisingly durable. This incomparable technique unites characteristic features of both painting and jewelry, and brings astonishing results to those rare artists who are eager to meet all the unexpected effects and all the difficulties it implies with great patience and passion.
