In China, copper oxide was introduced to the production of white porcelain during the Yuan Period (1271-1368). Many items like this were made during the Ming Period (1368-1644). At this time, copper oxide was used in diverse ways, including by creating patterns on the entire surface of a bowl. This bottle is thought to have been made around the end of the Yuan period or into the early Ming Dynasty. It is one of the very rare remaining examples that were imported into Korea. It does not display crackling. Japanese apricot flowers and chrysanthemums were painted using the technique of only portraying an object in black, with the shading adjusted and no lines used. The patterns used to portray the Japanese apricot flowers and chrysanthemums are similar to those found in white porcelain items dating back to the end of the Yuan through the early Ming Dynasties, but the brushstrokes appear to be weaker than those common in Yuan China.
