In this work, chemical properties, physical properties, and cause of stains on mosaics of Phra Maha Dhatu Nabhamethanidol and Nabhapolbhumisiri at Doi Inthanon National Park, Chiang Mai were studied. The mosaic colors were determined by Diffused Reflectance Ultraviolet-visible Spectrometer (DRS). The hydrophilicity properties of the mosaics were analyzed by contact angle measurement (CA). Characterization by infrared spectrometer (IR) revealed chemical functional groups on polyurethane of the mosaics. The morphologies and elements of the mosaics surfaces were analyzed by scanning electron microscope (SEM) with Energy Dispersive X-ray (EDX). Moreover, thermal properties of the mosaics were analyzed by Differential Scanning Calorimeters (DSC) and Thermogravimetric Analysis (TGA). Importantly, the stains, limestone-like samples, were analyzed by SEM-EDX. In addition, the pH of rain water in the area of Phra Maha Dhatus was measured and its elemental composition was analyzed by Inductively Coupled Plasma (ICP). Furthermore, algae class of moss in vicinity of Phra Maha Dhatus was identified. Finding the cause of the unwanted stains will lead to developing of an effective maintenance method for Phra Maha Dhatus.
