Interconnection of Structure with Whiteness and Translucency in Soft Porcelain

Аннотация

The structures of two types of English soft porcelain (bone china and parian) were investigated. The structural features of these materials that make it possible for the distinct properties of whiteness and translucency — uniformity, high content of the vitreous phase, well-developed interface of particles of the dispersed phase — to be combined in them are identified. It was found that a change in the conditions of firing affects the color characteristics of such porcelains. Parian possesses a more uniform structure than bone china, since the spread in the data on the average intergrain distance is significantly smaller with the same confidence probability 0.95 than in bone china.
