The items are made from thick sheets of cooper. The cooper is cut by means of a very thin saw that allows for precise and delicate slicing of the sheets. The colors are the natural shades of cooper, varying in degree due to special heating and cooling techniques. The texture and thickness are achieved by a hammering and flattening technique and a thin coating of transparent lacquer is applied to maintain the natural cooper color. There are combinations of additional materials such as glass beads and crystals, as well as colored metals (turquoise), blackened with acid.
