Integrated Evaluation of the Surface State of Glazed Porcelain

Аннотация

An integrated evaluation of the surface state of glazed porcelain by mechanical and optical means is made. It is shown that both methods can be used to determine the quality of a glazed surface, but they are more informative when used together. It is found that at the surface gloss is affected more by the width and not the depth of the asperities. In terms of the surface quality of feldspar glaze, samples made from hard porcelain are inferior to the sample made from bone china.
