While underglaze blue and overglaze enamels were often seen in separate styles, Ming potters also developed techniques for combining both methods on the same piece. These combined techniques demonstrate the ingenuity and versatility of potters during this time, and also the ways in which they sought to explore the interplay of different design techniques.
While underglaze blue was a core component of many Ming styles, some potters experimented with combining underglaze blue with sgraffito, a technique where designs are created by scratching through a layer of slip to reveal a contrasting colour beneath, and this combination of techniques adds both depth and visual complexity to the overall design scheme.
