white-ground technique

In ancient Greek vase-painting a technique in which figures were painted on a white background. The white-ground technique developed in the region around Athens circa 500 BCE.  It was used especially  for vases with ritual and funerary functions, because the painted surface was fragile compared to the other main Greek vase-painting techniques, black-figure and red-figure.
