Technical and Multi-Analytical Investigation of Sacred Tibetan Thangka Paintings

Thangkas are sacred artifacts; therefore, conducting scientific examinations of these paintings is not common. Based on this significant ethical challenge, a study published in the journal Heritage proposed a non-invasive three-stage technique that carefully investigates each layer of the painting, successfully assessing various production stages such as color notations, underdrawing, and painting techniques.
