The image is a photograph of a brown rectangular plaque with Chinese text written on it. The text reads "Joining Techniques for Blue and White Flasks". The text is written in both English and Chinese characters. Below the text, there is a description of the technique, which explains that porcelain flasks were made throughout the Yuan, Ming and Qing dynasties, from the rectangular flasks of the Yuan to the gourd-shaped flasks. The technique is used to create a smooth and shiny surface. The plaque appears to be mounted on a white wall.
