GREEN COPPER - In the Majolica method.
Green Copper: The plates below are copied from a photo; the original is in the Ceramic Museum of Barcelona. It was originally painted after 1400 AD in Paterna, a town in Valencia. When this style started it was known as Bicolor as it uses two colors only, manganese and copper green. There is also Tricolor which uses three colors; the most common colors for this method are green and blue.
Copper oxide is a green color used over and under other colors to create different colors and shades. If used heavily it becomes black with a silver shine when fired.
