“…These and other studies investigating the effects of different types of irradiations (see, e.g., Santis et al 2007;Gourier et al 2018;She et al 2020) have provided useful guides for those who want to approach the study of these pigments using this technique.…”

This review summarises the state-of-the-art of lead-based pigment studies, addressing their production, trade, use and possible alteration. Other issues, such as those related to the investigation and protection of artworks bearing lead-based pigments are also presented. The focus is mineralogical, as both raw materials and degradation products are mineral phases occurring in nature (except for very few cases). The minerals described are abellaite, anglesite, blixite, caledonite, challacolloite, cerussite, cotunnite, crocoite, galena, grootfonteinite, hydrocerussite, laurionite, leadhillite, litharge, macphersonite, massicot, mimetite, minium, palmierite, phosgenite, plattnerite, plumbonacrite, schulténite, scrutinyite, somersetite, susannite, vanadinite and an unnamed phase (PbMg(CO3)2). The pigments discussed are lead white, red lead, litharge, massicot, lead-tin yellow, lead-tin-antimony yellow, lead-chromate yellow and Naples yellow. An attempt is made to describe the history, technology and alteration of these pigments in the most complete manner possible, despite the topic's evident breadth. Finally, an insight into the analytical methods that can (and should) be used for accurate archaeometric investigations and a summary of key concepts conclude this review, along with a further list of references for use as a starting point for further research.

“…Litharge는 α-PbO로 tetragonal 구조이며 540℃이하에서 안정한 것으로 알려져 있다. 반면 Massicot 는 β-PbO로 orthorhombic구조이며 540℃이상에서 안정 한 것으로 알려져 있다 (Eastaugh et al, 2004) (Aze et al, 2008;Kotulanova et al, 2009;She et al, 2021;Vagnini et al, 2020;Zhao et al, 2019).…”

We examined degradation characteristics of lead based pigments(White lead, Red lead, Litharge) according to atmospheric environmet condition, for example UV, atmospheric gas(CO 2 , NO 2 ) and soluble salt. Painted samples not changed material compositions but were occured the color change(ΔE 4~31) after exposed UV irradiation. All samples were not affected by CO 2 gas not only color but chemical composition. However, samples were remarkably changed color exposed NO 2 gas and it was formed secondary product like as lead nitrate. Such as red lead and white lead samples' color difference were ΔE 2 and ΔE 10 respectively and became dark, along with litharge became bright and color difference was ΔE 5 after react with NO 2 gas. It confirm that NO 2 was influential factor than CO 2 in the case of same concentration. Furthermore salt spray test was taken to figure out soluble salt influence in fine dust. The result showed noticeable color change and secondary product was formed on samples' surface. The glue film peeled off or hole, and color changed around the secondary products. After salt spray, XRD pattern showed decrease peak intensity and lower crystalinity. As a result of salt spray test, white lead was formed new product litharge and litharge was formed litharge and minium. According to the results, influential atmospheric factors for conservation of paint pigments were UV, NO 2 , soluble salt, and litharge was most weakness throughout lead base pigments.
