Fig. 3: Sampling locations and surface microscope images of blocky samples.
From: Investigation on gilding materials and techniques of murals in Cave 55 at Mogao Grottoes
The figure displays a series of images illustrating the sampling locations on the original artifacts (left column) and corresponding surface microscope images (right column, labeled C55-1 to C55-6) of collected blocky samples. In the left column, red arrows indicate the precise locations from which blocky samples were extracted. The background shows the intricate artwork and context of the Mogao Grottoes murals. The right column presents high-magnification microscope images of each blocky sample, showcasing their surface texture, morphology, and any visible features. Each microscope image includes a scale bar (either 200.00 µm or 500.00 µm) to indicate the magnification level and the size of the observed features.
