Analysis Of Raindropglaze Of Famous Porcelain

Raindropglaze which invented in Song dynasty is a special accomplishment in the china history of China, it become a famous and precious kind of glaze of ceramic art in China and even in the world.This precious historical and cultural heritage died away after Ming-Qing dynasty, many ceramic artists dedicate to research it again, but the result is not very conformity, not have a unified cognition about the form mechanism of raindropglaze. The purpose of this paper is to reappear the firing methods under modern techniques through integrate and analysis modern technological, discuss the form mechanism and proper technical control condition based on the former knowledge and experience.The key point of paper is generate theory and firing element of raindropglaze, so theory and practice are on an equal basis to this paper. Introduction shows the properties characteristic and the origin name of raindropglaze, explicated the scope and methods of the paper. Chapter 1, we mainly introduce the history. Production of black glaze porcelain is a subject that we can not ignore in china history, the produce of raindropglaze is related with the development of black glaze porcelain, so we first review the development history of black glaze porcelain, then give an explanation about the time、ground and condition to the emergent of raindropglaze. Chapter 2 is theory analysis. We first analysis the composition of the raindropglaze, now we have know basically the formative factor via the analysis given by the China ceramics scientific research units; Then summarize the generate principle of raindropglaze. Chapter 3 is practice. According to the component analysis about the raindropglaze in chapter 2, we proceed to the trial about the glaze ingredient.We match the frit with the normal porcelain making raw material based on the local natural glaze material. We discuss the rational chemical composition scope of raindropglaze through orthogonal test. Results prove that natural glaze material and normal porcelain making raw material can both fired into raindropglaze so long as the chemistry composition is rational and craft is proper controlled. Furthermore, we find that rational craft control is critic to the produce of raindropglaze after firing system tests. We should note the impact of glaze layer thickness and frits fineness and other craft conditions to the quality of glaze at the same time. Finally, we focus on checkout and probe after firing, analysis and summarize some regular and experience about raindropglaze in accordance with the firing result, give the relevant state to its art performance.Under modern techniques and methods, the paper discusses the form theory and firing method of the raindropglaze. The success of our research will be helpful to modern ceramic artists to develop further of raindropglaze, thereby open up a more wide art field, carry forward the excellence historical and cultural heritage of raindropglaze.
