  • Chemical characteristics of whitewares excavated from the of official kiln of the Choseon Dynasty period in Gwangju, Gyeonggido have been stuied using x-ray diffraction, inductively coupled plasma atomic absorption spectrometry and energy dispersive spectrometry. This study shows that most of whitewares excavated from the kiln site are similar in chemistry to each other regardless of their excavated positions and that the their bodies were not made of feldspar minerals. However, the whiteware from sedimentation 1 of waste articles shows mineralogical characters different from those of other sites. This result is in accordance with the report that the whitewares from sedimentation 1 of waste articles have characters different from other sites. The whiteware glaze was produced from raw minerals of both lime and alkali-lime system resulting in wide variation in chemical composition.

  • This study aims to examine production technique of twelve white wares from the Gangneung Namyang-ri and Donghae Balhan-dong2(Samun-dong) kiln sites, Kangwon Province and characteristics of the used materials, and to find a correlation among materials of the excavated white wares. X-ray fluorescence sequential spectroscopy(XRF), X-ray diffraction(XRD), Dilatometer and Inductively coupled plasma mass spectrometry(ICP-MS), Inductively coupled plasma automic emission spectrometer(ICP-AES) were applied to determine the chemical composition, crystalline phase of samples, firing temperatures, trace elements and rare earth elements. When analyzing body crystalline phases of the white wares using the XRD method, quartz and mullite were extracted from all the samples. Though firing temperature of each sample was different, they were mostly fired at a temperature below $1200^{\circ}C$. Analyzing the excavated white wares using the Seger formula, compositional properties of white wares in Gangneung Namyang-ri kiln showed diffrently from the Donghae Balhan-dong2(Samun-dong) kiln. The body of white wares from Gangneung Namyang-ri kiln have higher raito of $RO_2$ and $RO+R_2O$ than of white wares from Donghae Balhan-dong2(Samun-dong) kiln site. The white wares from Gangneung Namyang-ri kiln and Donghae Balhan-dong2(Samun-dong) kiln were made of host rocks of the different geological origin, according to the result of rare earth elements analysis.

  • This study aimed to investigate the chemical properties and production techniques for white wares from the Gwirae-1ri 3rd, Songok-3ri 2nd kiln sites in Kangwon Wonju regions. Further, another aim was to determine the correlation among the materials used to produce the white wares. The analysis of white wares in Kangwon Wonju regions produced the following results. The excavated white wares were analyzed using the Seger formula, and all the samples showed similar clay sources ($RO_2:4.33-5.82$, $RO+R_2O:0.32-0.43$) and glaze sources. Moreover, the white wares were made of host rocks of the same geological origin, according to the results of the rare earth elements analysis. When the crystalline phases of the white wares were investigated via the XRD analysis, quartz and mullite were found in all the samples, and their proportions were similar to each other. Although the firing temperatures for the samples were different, most were fired at a temperature below $1,200^{\circ}C$, with some being fired at temperatures as low as $1,000{\pm}20^{\circ}C$.

The Characteristics and Background of Gwanyo's Production of White Porcelain with "Byeol(別)" Inscription in 16th and 17th Century Joseon (조선 16~17세기 관요(官窯) '별(別)'명 백자의 성격과 제작 배경)

  • This paper discusses the characteristics and background of the production of white porcelain with the "Byeol(別)" inscription. Such porcelain was produced by the government-run porcelain kiln, Gwanyo(官窯), in the 16th and 17th centuries (from the 1560s to the 1640s), during the Joseon dynasty. The white porcelain ware, inscribed with either the term Byeol or "jwa(左)" and "u(右)," constituted a dual production system of white porcelain by Gwanyo starting in the 1560s. However, to date, few studies have examined Byeol-inscribed white porcelain. This, therefore, makes it difficult to achieve a comprehensive understanding of the evolution of inscriptions on the white porcelain produced by Gwanyo in the 15th to 17th centuries. Besides a regular annual stock of porcelain(年例進上磁器), Gwanyo also produced and supplied additional porcelain ware, or Byeol-gi, at the behest of the royal family or the court of Joseon. Byeol-inscribed white porcelain is a form of Byeol-gi, produced through extra firing, or Byeolbeon(別燔). According to use, Byeol-gi can be categorized as an item for national use(國用) or an item for internal use(內用). However, if the porcelain only carries the "Byeol(別)" inscription, it is difficult to identify its characteristics. Furthermore, as part of the annual production of porcelain was for the supply of Byeol-gi, and then for other purposes, the white porcelain came to be inscribed with dots indicating a change in ownership. In the 16th century, the royal family increased its consumption of white porcelain based on Shinyu Gongan(辛酉貢案), the government's fiscal reform measures. To guarantee a stable supply of exceptional Byeol-gi in light of Gwanyo's decline in the 1560s, the royal family benefited from the inscription of "Byeol." The white porcelain produced by Gwanyo was divided into annual offerings-those with the inscriptions "jwa(左)" and "u(右)"-and Byeol-gi, those with the inscription of "Byeol." They were managed separately from the commencement of production. Byeol-inscribed white porcelain was produced until the 1640s. During the mid-and late 1640s, Byeolbeon was temporarily suspended. Starting in the 1650s, the white clay used to produce the annual stock of white porcelain was sourced from regions other than those providing the clay for Byeol-gi production. The former used clay from Wonju(原州土) and Seosan(瑞山土), while the latter used clay from Gyeongju(慶州土) and Seoncheon(宣川土). According to the literature, the clay from Gyeongju and Seoncheon was much cleaner than that from Wonju and Seosan. Byeolbeon thus underwent a transformation, whereby production was separately managed, right from the stage of white clay mining. Ultimately, the need for the separate management of Byeol-gi through inscriptions diminished, resulting in the disappearance of Byeol-inscribed white porcelain.

  • This paper deals with the cultural and ideoligical background of the landscape designs on Joseon blue and white porcelains in the late Joseon period, and involves the government painters in the official kiln. Dongjeongchuwol-design (동정추월문), painted the full-moon night scene of Dongjeong lake on Jeseon blue and white porcelains, was in fashion in the late Joseon period. It didn't reflected the entirely realistic subject comparing to the painting circles at that time, but the principle and aesthetic appreciation of Royal family who leaded the official kiln. And Sansuinmul-design (산수인물화). painted the man of great caliber in the ancient history with mountain scenery, was similar to the painting manuals such as Gossihwabo (고씨화보) and Dangsihwabo (당시화보). It was a counterpart of Dongjeonchuwol-design on Joseon blue and white porcelains in the late Joseon period. These designs were painted into ogival-shaped frame (릉화창) on the blue and white porcelains in most cases, and adjusted to shape of porcelain. The landscape designs on Joseon blue and white porcelains became stereotyped, involving subjects of folk painting in the late 18th Century and the early 19th Century. This essay will be just a start to research into the landscape designs on blue and white porcelains in the late Joseon period, even though we seldom find works providing strict chronology among some works to the public.

  • This study examined the chemical characteristics and the microstructure of Goryeo whiteware which was excavated in the kiln site Yucheon-ri, Gangwon-do, the southern part of South Korea. this area is considered to be used in the middle of the time of Goryeo Dynasty. We analyzed the chemical characteristics comparing Goryeo Whiteware from Seo-ri, Jungam-ri, Bangsan-dong and The temple site of Beopcheon. Based on the analysis, we confirmed the properties of raw material for making pottery. It is featured that body composition of Goryeo Whiteware from Yucheon-ri contains high silica and low solvent. However, the contents of the glaze are vice versa. Goryeo whiteware tends to contain larger part of oxide than that of titanium oxide, which applies to Goryeo Celadon. the whitewares during the early days of Goryeo Dynasty varies in components depending on kilns, whereas it does not mean that chronological changes happened in components. The whiteware shards from Yuchoen-ri have a similar aspect. The whiteware shard from the temple of Beopchen differ in composition, Thus they are estimated to have been produces and shipped from various sites. In conclusion, we judged that the component difference among Goryeo whitewares stems from production environment and origin of raw materials rather than chronological changers.

  • This study aims to research the relationship between whitewares and their rare materials from the site of Yanggu and Bunwon through the componential characteristic of the excavated whitewares from the 1st and the 2nd kilns of Chiljeon-ri in Bangsan-myeon, Yanggu-gun. As a result, the sherds were devided according to the chemical compositions of the body and the glaze via their respective production era. However, it considered that the whitewares from Chiljeon-ri had been manufactured with geochemically similar materials and the production process, such as refining and combining materials, had been different. It assumed that the firing temperatures of the whitewares from Chiljeon-ri were around $1,100-1,200^{\circ}C$ and substantially lower than for general whitewares. In the componential analysis, there were disparate properties in the cobalt pigment, which contained trace elements and rare earth elements. A review of the literature revealed a correlation between the whitewares from the late Chosun kiln site in Bunwon-ri and the raw materials from Yanggu-gun, but this was there were various techniques for refining and combining materials in Bunwon-ri.

  • The material characteristics of Chos$\breve{o}$n whiteware were investigated by analyzing and comparing the body and glaze compositions of whiteware shards excavated at the Kwangju royal kilns, Ch'unghyodong, and four other local-level kilns. In Korea, the rise of whiteware technology began in the early years of the Chos$\breve{o}$n dynasty, when the indigenous tradition of Kory$\breve{o}$ celadon was strongly influenced by the whiteware aesthetics of the Chinese Ming dynasty. The Kwangju royal kilns eventually made hard-textured whiteware of a quality equivalent to that of the Chinese by using type of porcelain stone that contained slightly less $Fe_2O_3$ and $TiO_2$ and slightly more $K_2O$ than that used for celadon. In contrast, the potters of Ch'unghyodong achieved the same level of quality by finding and using a totally different material: kaolinitic clay. The porcelain stone used at the Kwangju kiln was commonly found in Korea and south China, whereas kaolinitic clay (which has a high aluminum content) was typically found in north China, and was only rarely used in Korea. The flux component of the glaze compositions was mostly limestone, first in burnt form and later in crushed form, and the clay component was often glaze stone, which was a finer-grained porcelain stone with a higher proportion of feldspar. In the future, this comparative analytical study of Korean whiteware components should be extended to the $18^{th}$- and $19^{th}$-century kilns that are currently being excavated at a rapid pace.
