MATALE — In a pioneering application of modern scientific conservation, the Central Cultural Fund (CCF) and the Department of Archaeology have commenced a high-tech restoration initiative targeting historic 18th-century Kandyan-era cave and shrine frescoes across the Matale district.

Using portable Raman laser spectrometers and multi-spectral infrared cameras, conservation scientists can analyze the chemical composition of mineral pigments and organic binders without scraping or damaging the fragile plaster substrates. This non-invasive diagnostic process identifies microscopic micro-fractures, salt efflorescence, and moisture intrusion within the painted layers.

In parallel, digital heritage technicians are creating millimeter-accurate 3D point-cloud scans of the temple interiors to create permanent, high-definition digital twins stored in national cultural repositories.

Archaeological authorities noted that combining centuries-old conservation ethics with modern optical science ensures that Sri Lanka's irreplaceable religious wall art remains protected for future generations while providing scholars worldwide with immersive virtual access.
