The image is a slide from a presentation about material/quality changes in ancient Buddhist sculptures. The slide has a white background with black text. The title of the slide reads "Material / Quality changes" and below it, there is a subtitle that reads "Hundreds of years of history have left the vestiges of time on ancient Buddhist sculpture. For instance, when unearthed, they bear the traces of the surrounding environment where they were buried. In fact, the sculptures were usually buried and then covered with some material. For instances, it is very common to find traces of soil stuck to the sculptures' surface. In other cases, it's possible to find examples of natural changes happening to the sculptural body, such as color fading phenomenon, gilded decoration flaking, surface erosion, and hardening of the surface's layers. Simply resulting from the age of the sculptures. All these parameters can be taken into account for evaluating the sculpture's dating."
