Pigments used paintings, ornaments, weapons and various objects have been recognised as important elements to ascertain the history, manufacturing technique and cultural migration. Since the understanding of composition of pigments by analysis began in 1963, its technique and methodology has much advanced in recent years; recent study used the portable X-ray Fluorescence as non-destructive analysis has been practiced in particular. However the study on pigments necessitates overall and systematic research because it is difficult to understand periodical and regional use of pigments. by fractional studies. Therefore this research investigates the coloring materials and painting techniques of the scroll painting depicting preaching scene of Sakyamuni Buddha in Daeungjeon Hall, a main hall of Bulguk temple, through scientific analysis and comparison of various pigments which had been applied to the buddhist paintings of Joseon Dynasty. Consequently, it is confirmed that the scroll painting used pigments of white lead[$2PbCO_3{\cdot}Pb(OH)_2$] for ground layer and used mixture of different pigments such as cinnabar (HgS) minium($Pb_3O_4$) malachite($2CuO{\cdot}CO_2{\cdot}H_2O$) hematite($Fe_2O_3$) gold(Ag) for presenting various colors on the painting layer. It has been also believed that mineral pigments were applied to the scroll painting, yet it is difficult to confirm whether it is natural or synthetic pigments because the crystal structures of pigments were not analyzed. The results of this study, however, provide useful reference data for the understanding of the components of pigments and manufacturing techniques of buddhist scroll paintings, in particular, of Joseon Dynasty.

This study analyzed the pigments used in two portraits of Sim Hui-su using scanning electron microscopy/energy dispersive spectroscopy(SEM/EDS), X-ray diffraction(XRD) analysis, and microscopic observation, and then compared the results to those from nondestructive analysis. It was estimated that cinnabar/vermilion and minium were used for the red pigment, azurite for the blue pigment, atacamite for the green pigment, and lead white for the white pigment. These results were compared to the pigments of six portraits with a similar format, full-length official-attire portraits from the $17-18^{th}$ century Joseon period. It was revealed that the composition of the pigments used in the portraits varied depending on the date of production. Iron oxide, another red pigment, was used in the $18^{th}$ century. As for the blue colorant, smalt was used in the late $18^{th}$ century, whereas it was absent until the early $18^{th}$ century.

We have suggested effective P-XRF analysis method for pigment painting layer by calculating penetration depth of X-ray. This experiment calculated that X-ray generated from P-XRF was possible penetration until 1.17mm deep in the pigment painting. Based on the experimental results, analysis for eight color pigments on wall paintings in Ssanggyesa Main Hall, most pigments were painted traditional pigments. However pigments on recently restorated wall painting were used synthetic modern pigments.

The purpose of the present study is to determine the species of red and green pigments used on paintings of Korean temples and also to compare the two pigments according to the particle characteristics. The component analysis shows that the red pigment consists of cinnabar, hematite, and minium and the green pigment are composed of atacamite, celadonite, and malachite. The result suggests that mixture of various pigments were applied to the painting. When it comes to the particle characteristics, there are various hedral or anhedral shapes such as sharp, long, angular, and platy shapes even in the same cinnabar. In addition, the green pigment also shows a similar pattern with those of the red pigment. Up to now, an identification of minerals has been relied on examination of component and crystal shape. However, it is notable that using form related characteristics can be a better and useful method not only for categorization of pigments which are similar in terms of color and species but also specific index.

The analysis of danchung pigments at the Geunjeongjeon Hall in the Gyeongbokgung Palace were carried out by EXRF and MXRD. The analytical results showed that mineral pigments were employed for the inside of the Geunjeongjeon Hall. The main ingredients of green pigments were chalcanthite and celadonite. Red pigment was cinnnabar. It was also revealed that synthetic pigments were applied for the outside of the Hall. Yellow pigment was chrome yellow. The main ingredients of red pigments were red lead and hematite. Green pigments were emeral green and chrome green. Lazurite was employed for blue pigment and titanium dioxide for white one.

The purpose of this study is to reveal that coloring status and the degree of damage and the kinds of pigments used in large buddhist painting (Gwaebultaeng) of Tongdosa temple using a scientific analysis methods. It was observed that the physical damage patterns of the Gwaebultaeng were folding, lifting, fading, and peeling. Lead red, cinnabar and organic pigments were used as red pigments. Malachite and atacamite were used as green pigments, azulite and lazulite were blue pigments, lead white and talc were white pigment. It is estimated that overlapping organic pigments on the lead white were used as the yellow pigment and carbon was the black pigment. Through the analysis of the particle status of the pigments, it was confirmed that different types of raw materials were used for the green pigment, and the crystal form was easily distinguishable. Also, the dark blue color and the light blue color differed from each other depending on the size and shape of the raw material particles. Yellow and purple colors were organic pigments which did not have a graininess. The yellow and purple colors were organic pigments free from the graininess, and the pigments of dark red pigments was found to be mixed with the orange color pigments and carbon particles.

A gujangbok is a king's silk ceremonial robe embroidered with nine symbols that represent the essential virtues that a king needs to govern his country. The National Museum of Korea currently own a gujangbok worn by King Gojong in the late Joseon Dynasty. The robe is painted with various colors, including red, yellow, blue, green, and gray. μ-XRF and analysis was conducted on the pigments, and it was found that the red color was made from cinnabar, the yellow color was gold and brass, the blue color was a blue organic pigment and white lead, the green color was a synthetic pigment composed of copper and arsenic, and the gray color pigment was silver. Also, the pigments were compared to those used to make the patterns of a queen's ceremonial robe and a front cloth panel, both made around the same time and also owned by the National Museum of Korea. The comparative analysis revealed clear differences and similarities between the various pigments. The resulting data expect to serve as a useful foundation research for future studying of the pigments used by the Joseon royal court in the late nineteenth century.

This study, a part of scientific analysis of the 23 Neolithic red earthenwares excavated from southeastern coast and islands. We analyzed earthenware through statistical method and hardness analysis of clay, following the analysis of clay composition, its firing temperature, pigment composition and its thickness. Clay composition was analyzed by using ICP-AES and XRF, and then Principal Component Analysis (one of multivariate methods) was used for classification. As a result, clay of the earthenware was classified into 3 groups(Bumbang, Youkjido and other sites). In addition, hardness analysis of pigment and clay based on the depth of earthenware surface showed that pigment layer containing lots of Fe₂O₃ had higher hardness than clay part, which can be interpreted that Fe₂O₃ contributes to raising hardness in case of high temperature firing. The fact that pigment hardness is higher than that of clay part implies that pigment was applied before firing.
