The decoration consisted of painted, stamped, and neat impressed patterns. The painted decoration is normally in black on a red-slipped ground. The black colouring agent is believed to be magnetite or black oxide of iron, applied in a finely divided state with a brush before firing. The painted designs comprise triangles, loops, festoons, wavy lines, conventional flowers, cocks or peacocks, etc.
