Fig. 2: Sampling locations and surface microscope images of gold foil 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 GF-1 to GF-6) of collected gold foil samples. In the left column, red arrows indicate the precise locations from which gold foil 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 gold foil sample, showcasing their surface texture, morphology, and any visible features. A scale bar of 200.00 µm is provided for each microscope image to indicate the size and level of detail.
