“…In the presence of metal catalyst in the particulate matter, the sulfur oxides reacted with calcium carbonate mineral in the stones and produced gypsum crust (Charola et al, 2007; Sabbioni et al, 2001; Siegesmund et al, 2007). As an unstable weathering product, gypsum crust is hazardous, and it can bring about many serious damages such as esthetic alteration, surface powdering, and exfoliation for the stone relics (Saheb et al, 2016; Tecer, 1999; Török, 2003). In essence, these damages are attributed to the fact that gypsum is much more soluble than calcite in water (Lebedev & Kosorukov, 2017; Sassoni et al, 2017); the gypsum crust is more likely to be carried away by the natural precipitation such as rain, dew, and snow, leading to the accelerated surface recession of the limestone relics; and the historic carvings on them will fade out as well.…”

A novel preparation method of calcite layer was explored for the conservation purpose of the surface sulfation limestone artifacts. In this method, the alcoholic solution of calcium glycolate was used as a precursor of calcite layer. After application on the surface of gypsum crust on limestone by spraying, calcium glycolate can combine with the carbon dioxide spontaneously and form a compact calcite layer. The obtained calcite layer can act as a shelter and can prevent the gypsum crust from the dissolution damage of the natural precipitation. The protective properties of the calcite layer were investigated by scanning electron microscopy with energy dispersive X‐ray spectroscopy (SEM/EDS), X‐ray diffraction (XRD), infrared spectroscopy (FTIR), water erosion resistance, water absorption, colour difference, surface strength, and hardness test. The results revealed that the water erosion resistance, surface strength, and hardness of the treated sample were increased remarkably. Meanwhile, the intrinsic physical properties such as porosity, capillary absorption, and appearance were not affected obviously, indicating a good compatibility of the proposed protection method.
