The image is a photograph of a sign that reads "The Advances in Porcelain-making Techniques". The sign is written in black text on a white background. The text is in Chinese and translates to "The porcelain produced in the Han Dynasty (both Western Han and Eastern Han) inherited the fine traditions of its primitive counterpart and featured more delicate texture. By Wei, Jin and the Southern-Northern Dynasties, porcelaine-making techniques came close to maturity. White porcelains produced during the northern dynasties marked a major breakthrough in porceram-making technique. Production started during this period of white porcerain with green hues, which laid the groundwork for painted porcelian created by the following generations." The sign appears to be located in a museum or exhibition space.
