Using advanced multi-spectral imaging and neural-network-based script recognition, an international team of scholars has successfully deciphered a series of 9th-century Siddham script palimpsests discovered in a remote Silk Road stupa. The texts contain previously unknown Sanskrit treatises detailing geochemical assaying and the systematic classification of rare earth minerals used in metallurgical flux.
The manuscripts, likely originating from monastic centers in North India, describe protocols for identifying mineral impurities through flame coloration and reaction with organic acids. This discovery suggests that ancient Indian scientists possessed a highly empirical understanding of mineralogy that was shared across the Silk Road network, bridging the gap between alchemical practice and modern chemical science.
