The image is a photograph of a sign on a wall that reads "Tri-color Pottery and Huangye Kiln in Gongyi". The sign is written in black text on a beige background. The text is in Chinese and translates to "Kaolin-clay bodies applied with colorful glazes containing ingredients of iron, copper, cobalt and manganese, when re-firing, resulted in what was known as the tri-color pottery of the Tang Dynasty. During the firing process, glazes of different colors intermingled with each other, leading to a natural artistic effect. Huangye kiln in Gongyi was a leading tri-colour pottery producer during the Tang dynasty."
