The designs are made using colored oxides and applied with paintbrushes made from wood or, commonly, the recycled plastic shell of a ballpoint pen and hair left over from a child's haircut. Depending on the intricacy of the design, the painting can take hours, each applied color undergoing still another hand polishing process. When all the painting is complete, the pot is set out in the open air and can take anywhere from two days to a week to dry.
The outlines of the design are often carved, defined in a relief style by using a sharp instrument to delicately pick off only the top-most layer of clay, intentionally leaving the rough surface exposed. This tool can be made from the spokes of a bicycle wheel or the spines of a broken umbrella that have been sharpened by a stone.
