The image is a photograph of a plaque or plaque with Chinese text written on it. The text is written in black ink and is in a traditional Chinese font. The plaque appears to be made of a light-colored material, possibly porcelain or ceramic, and is mounted on a white wall. The background of the plaque is plain white.

The text on the plaque reads "Proto-porcelain Production" in both English and Chinese. Below the text, there is a description of the product, which states that China is the birthplace of porcelaine and proto-porcain, and that it can be traced to the Erlittou Culture. Made from kaolin clay, some shang-shang-porcerain was applied with a mixed glaze containing lime on the surface and inside parts of the rim before firing at around 1,200°C. The glaze gave the vessel a translucent grayish-purple color. The vessel produced in this way was hard and non-porous or slightly porous. In the Western Zhou, progress in technology led to greater diversity and more widespread use of proto-porecain.
