Colored Clay - White clay body is mixed with color stain. Most mason stains are commonly used. For darker colors such as black, brown, or dark green, a 3-10% color stain is good enough. For light colors such as yellow, pink, or light green, it will need 10-15% of color stain.
Carving or Incising on Pot - The pot has to be leather hard for cutting cleanly. The design could be drawn on the clay surface with a pencil lightly as a guide. However, some crafters prefer to carve on a dried pot in order to achieve finer details. A mask should be worn as working on a dried pot to minimize dust inhalation.
