Ono Hakuko's ceramic works are elegant in form and classical in decoration. Ono excelled at the ancient Chinese technique of applying gold foil beneath the glaze, having learned this difficult skill from Katô Hajime. Gold foil is applied to the surface and then adhered with a layer of lacquer, which melts in a low-temperature firing. Then the piece is fired again after being glazed with a translucent colored glaze. Geometric designs in gold sparkle from below Ono's application of translucent blue or yellow glaze, giving an impression of delicacy and sumptuousness.
