In addition to the predominant black and white designs, were Cizhou pillows decorated with colorful lead-silicate glazes in a technique that first flourished in the eighth century during the Tang dynasty. Called san cai or 'three-color' ware, this technique usually combined green and yellow glazes on a cream slip to produce a three color effect.
