They are handmade by me in my own special (secret) "casting with metal clay technique". They are made with copper clay which hardens and turn to solid copper when heated in a kiln to about 900 °C. They are oxidized using heat to a color resembling of autumn leaves. The color is sealed with jewelers wax.
