This is an emergency! Does anyone know what these are? They are all Tibetan maps of Shangri-La!

At first glance, I thought it was a pigment ground from natural minerals, which was mainly used for painting Thangka and murals.

But because Tibetans also know a lot of mineral medicinal materials, there is no way to be 100% sure.

Because dzi beads can be used as medicine, but not as pigments. However, dzi beads have another function when painting Thangka or murals, that is, they are used to polish the place where gold is painted, which will make the effect of gold stand out. However, most of them use special pens to polish agate at the writing position, and few use dzi beads.
