This thesis presents the first detailed study of the life and work of Seifu Yohei III, in either English or Japanese. Seifu Yohei III (1851-1914) was one of the leading ceramic artists of the Meiji period and highly acclaimed both in Japan and abroad during his lifetime. Being a literati-style painter and an unabashed Sinophile, Seifu created works that display the distinctive characteristics of Qing porcelain. The multi-faceted character of this artist provides an opportunity to explore crucial issues concerning the transformation of Japanese art in general at the beginning of Japan's modem age. The clientele for such works was an elite with similar predilections for Chinese-style wares, though patronage of his works extended even to the Imperial Household of Japan. A study of Seifu Yohei III demonstrates that Japanese ceramics cannot be discussed in terms of a linear, uniformly progressive development mirroring the Westernisation of Japan. Seifu's career reveals the co-existence of what might normally be perceived as irreconcilable factors in terms of its regional, social, economic and cultural environments, often involving interaction with China. Each chapter takes up a different issue surrounding Seifu Yohei III in the context of the production and consumption of art in Meiji Japan. This interdisciplinary analysis of the life and work of Seifu Yohei III also sheds light on the social, economic and cultural factors affecting other potters of the Meiji era. It takes on previously neglected issues concerning what happened in the area of ceramic production inside Japan and, more broadly, in East Asia as a whole.

No Estudo 1, testou-se o efeito da limpeza ultra-sônica pós condicionamento com ácido fluorídrico na resistência de união de um cimento resinoso às cerâmicas reforçadas por disilicato de lítio e leucita. No Estudo 2 avaliou-se o efeito do tratamento térmico de diferentes silanos na resistência de união entre o cimento resinoso e a cerâmica reforçada por disilicato de lítio. Para o Estudo 3, utilizou-se uma porcelana à base de zircônia e 5 cimentos resinosos (sendo quatro cimentos auto-adesivos e um convencional) os quais foram testados após 24 horas ou um ano em armazenamento em água. No Estudo 4, avaliou-se o efeito da aplicação de "primers" para estruturas à base de ligas metálicas na resistência de união de um cimento convencional e um cimento auto-adesivo à porcelana à base de zircônia. Para os Estudos, foram utilizadas placas de cerâmicas reforçadas por disilicato de lítio, leucita e zircônia nas dimensões aproximadas de 10 mm de comprimento, 5 mm de largura e 1 mm de espessura. As superfícies das porcelanas foram tratadas de acordo com os objetivos de cada Estudo e espécimes de cimento resinoso em formato de cilindro foram confeccionados nessas superfícies, utilizando-se de uma matriz de Tygon com dimensões internas de 0,7 mm de diâmetro e 1 mm de altura. O ensaio de microcisalhamento foi realizado em máquina universal de ensaios (Instron 4411) e os valores de resistência de união apresentados em MPa. A análise dos dados foi realizada através da Análise de Variância (2 fatores) e teste de Tukey (5%) para todos os Estudos. No Estudo 1, a aplicação de ultra-som na peça condicionada aumentou a resistência de união em ambas as cerâmicas testadas. O uso do tratamento térmico da amostra de cerâmica silanizada não aumentou a resistência de união, independente do silano utilizado no Estudo 2. No terceiro Estudo, observou-se redução de resistência de união à zircônia após um ano de armazenamento em água para todos os cimentos estudados. No Estudo 4, o cimento auto-adesivo apresentou maior resistência de união que o convencional e o uso do Metal Primer aumentou a resistência de união de ambos os cimentos à superfície da zircônia. O uso do ultra-som nas peças cerâmicas condicionáveis pode aumentar a resistência de união do cimento resinoso, enquanto o tratamento térmico do silano não resultou em efeito significativo. O uso de primers para metal pode aumentar a resistência de união dos cimentos resinosos à zircônia, enquanto, o efeito do armazenamento em água por um ano pode causar redução significativa dessa resistência. / Abstract: The objective of this study was to evaluate the microshear bond strength of resin cements to lithium disilicate, leucite or zirconia-based porcelain. The Study 1 tested the effect of ultrasonic cleaning after fluoridric acid etching on the bond strength of resin cement to a lithium disilicate and leucite based porcelain. The Study 2 evaluated the effect of different silanes and silanizated ceramic heating on the bond strength of a resin cement to the surface of a lithium disilicate-based ceramic. For Study 3, it was used zirconia based porcelain and 5 resin cements (one conventional and and four self-adhesive), which were tested after 24 hours or one year of storage in water. In the Study 4, it was analyzed the effect of alloys primers on the bond strength of a conventional cement and a self-adhesive cement to -zirconia-based porcelain. Porcelain plates of lithium disilicate, leucite and zirconia with approximately dimensions of 10 mm lenght X 5 mm wide x 1 mm thick were prepared and used in this study. The porcelain surfaces were treated following the the objectives of each study. The resin cement cylinder shaped specimens were prepared on these surfaces using a matrix of Tygon tubing with internal dimensions of 0.7 mm in diameter x 1 mm high. Microshear test was conducted in a universal testing machine (Instron 4411) and the values of bond strength presented in MPa. Data analysis was performed using analysis of variance (two-way Anova) and Tukey test (5%) for all studies. In the Study 1, ultrasonic cleaning increased the bond strength for both ceramics. The heating of silanizated ceramic did not increase the bond strength, regardless of the type of the silane used in the Study 2. In the third study, it was observed reduction of bond strength to zirconia porcelain for all cements studied after year of storage in water. In the Study 4, the self-adhesive cement showed higher strength than the conventional one, and the use of Metal Primer products increased the bond strength for both cements to zirconia surface. Ultrasound of conditioned ceramic can increase the bond strength of resin cement, while the heat treatment of silane did not result in a significant effect. The use of alloys primers can increase the bond strength of resin cements to zirconia, conversely, the water storage for one year may cause a significant reduction of bond strength. / Mestrado / Dentística / Mestre em Clínica Odontológica

本文以早期中葡貿易瓷器為主要研究對象，具體時期為澳門開埠前期，即大約1553年至1600年之間。根據文獻記載，葡萄牙人於1514年首次到達中國，此後由於中葡關係一度交惡，未得官方許可的葡商遊走於中國海域的各個離島，與沿海商人暗中進行走私貿易。直到1553年（葡文獻記載為1557年），葡萄牙人佔據澳門，並逐漸將其發展成為葡萄牙對中及亞洲貿易的主要據點，中葡貿易的規模才迅速增長，並趨穩定，保持了隨後近一個世紀的繁盛。 / 澳門開埠，標誌著中葡貿易進入一個新的階段，這一變化亦清晰地反映在作為商品的瓷器之上，除數量的激增外，為了滿足歐洲市場的需要，一批具有全新風格及功能的外銷瓷器被生產出來，這類瓷器即是本文研究和討論的重點。以往由於實物資料的缺乏，以及對克拉克瓷研究的單一關注，學界對澳門開埠前期貿易瓷器面貌的認識長期不足。因此，本文將集中對此時期的貿易瓷器進行系統的整理和分析。 / 學界通常認為，十六、十七世紀之交流行的克拉克瓷器（Kraak Porcelain），是外銷青花瓷器專為歐洲市場創造的全新風格，然而筆者通過近年來對澳門及葡萄牙本土遺址出土瓷器材料的研究與考察，認為這種風格的創新，在澳門開埠不久（即十六世紀中期）已見端倪。因此，本文將選取葡萄牙內陸科英布拉市一處修道院遺址出土的中國瓷器，作為澳門開埠前期貿易瓷器的代表材料，與此前暢銷於東南亞及中東市場的中國瓷器、中葡貿易離島時期所交易的瓷器進行比對，由類型、紋樣及尺寸等方面入手，論證貿易瓷器品貌的巨大轉變發生在澳門開埠前期（1553-1600年）。並在此基礎上，結合文獻檔案及實物資料，進一步論證瓷器面貌發生轉變的原因，是對於歐洲市場審美與功能需要的契合，得出專供歐洲市場的中國外銷瓷產生於澳門開埠前期的結論，挑戰對於克拉克瓷器的傳統認知。 / 最後，本文對貿易瓷器生產的不同階段及其紋樣及類型的發展趨勢進行考證，與後期出現的克拉克瓷器進行比對，理解貿易瓷器的生產革新對於克拉克瓷的先導作用。研究結果亦可釐清十六世紀中後期外銷瓷器的類型與紋樣特徵，完善我們對明代瓷器風貌的認識。 / This thesis mainly focuses on the research of Sino-Portuguese trade porcelain during the early days of Macau’s colonization (between 1553 to 1600 AD). According to historical texts, the Portuguese first arrived in China in 1514 AD. However, because of poor diplomatic relations, the Portuguese resorted to smuggling along the Chinese coasts and neighbouring islands, since they were forbidden to trade near the mainland. It wasn’t until 1553 AD (1557 AD in Portuguese historical texts), the Portuguese occupied Macau and gradually developed it into a main stronghold of Sino-Portuguese maritime trade. Since then, the Sino-Portuguese trade rapidly grew and transitioned into a stable, prosperous business, which lasted almost a century. / Macau’s colonization signified a new stage in Sino-Portuguese trade, which was clearly reflected on porcelain goods. In addition to the increase of quantity, export porcelain with new styles and functions were produced to meet the European market’s demand. These products are the focus of this thesis. In the past, academic research on porcelain during the early period of Macau’s colonization was inadequate due to the lack of first-hand material and the sole focus of Kraak Porcelain. Therefore, this thesis will systematically analyze and categorize the export porcelain during this time period. / Academics generally believed that Kraak Porcelain between the 16th and 17th Centuries was a new trend for the European market. However, through the research and investigations of porcelains unearthed in Macau and Portuguese sites, the writer believes the trend already existed during the early period of Macau’s colonization (mid-16th Century). Therefore, this thesis will use the porcelains unearthed in a monastery site at Coimbra, Portugal as typical research materials, and compare them with the porcelains traded in the Southeast Asian and Middle Eastern markets, along with the early trade porcelains between Chinese and Portuguese merchants (before 1553). Thereby proving the transition and time period of the emergence of export porcelain through types, decoration and dimension. On this basis, combined with historical information and factual evidence, further discuss the change of export porcelain, and its correlation with the aesthetic and functional requirements of the European market. / Last but not least, this thesis will attempt to make the reader understand the transition and innovation of export porcelains may play a leading role to the development of Kraak Porcelain. This will be achieved through comparing the investigation of the different developmental stages of the types and decoration of export porcelains, with Kraak Porcelain, which appeared at a later time period. The research results can also clarify the characteristics of types and decorations of export porcelains during the mid and late 16th Century, which provides a holistic understanding of Ming Dynasty porcelain traits. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / 王冠宇. / Thesis (Ph.D.) Chinese University of Hong Kong, 2015. / Includes bibliographical references (leaves 254-270). / Abstracts in English and Chinese. / Wang Guanyu.

Materiais complexos como porcelanas e porcelanatos tem suas propriedades maximizadas quando atingem altas densidades finais após a sinterização. Contudo, a sua formulação contém no mínimo quatro matérias- primas diferentes, sendo o caulim a maior parte, mas também contendo quartzo e feldspatos. A granulometria final da mistura é controlada por uma única etapa de moagem de todos os materiais misturados. O objetivo deste trabalho foi obter combinações de diferentes granulometrias de ortoclásio, albita e quartzo com uma única granulometria de caulim através de cálculos de máximo empacotamento com o objetivo de alcançar a máxima densidade a cru, mantendo-se uma única composição química final. Os resultados mostraram que utilizando o conceito de empacotamento de partículas e otimizando a distribuição granulométrica foi possível obter corpos de prova com maiores densidades finais, menor retração final, além de reduzir a temperatura de queima, o que impacta diretamente no custo de produção. / Complex materials such as porcelain and porcelain stoneware have maximized their properties when they reach high final densities after sintering. However, formulations contain at least four different raw materials, where the kaolin is the major constituent, but also quartz and feldspars. The final particle size of the mixture is controlled by a single step milling of all materials. The attempt of this paper is to make different combinations of particles size distributions of orthoclase, albite and quartz with a single particle size of kaolin by calculation of maximum packing in order to achieve maximum density crude keeping same final chemical composition. The results showed that using the concept of particle packing and optimizing the particle size distribution was possible to obtain specimens with higher density end, the lower total shrinkage, in addition to reducing the firing temperature, which directly impacts the cost of production.
