Abstract:   (792 Views)
The ceramic articles taken out of the glaze kiln may have one or more defects for various reasons, which wastes the efforts of the potter and the craftsman. Some of the most common defects that occur in glazes are bubbles, pinholes, pits, blisters, metal lines, crazing, peeling (shivering), crawling, leaching, clouding, color change, specking, sulphuring, starving and popping (chipping). Since bubbles and defects resulting from it, such as pinholes, holes and blisters, are the most common defects, which almost every tableware, sanitaryware and tile factory is involved with, and it is very difficult to remove them completely, in this article, considering the available references and field experiences, various aspects of these defects, including the reasons for their formation and the way to fix them is investigated. Many references and books have been written about glaze, but unfortunately, in most of them, the discussion about the defects of the glaze, especially the bubble and the defects resulting from it, is on the sidelines and is not properly investigated. The point that the authors came across while reviewing the references is that, firstly, not much research has been done on this issue. Secondly, the written works are not very comprehensive. Thirdly, most of the articles are related to tiles and not tablewares, which despite the similarities, have many differences. Fourthy, most of the issues adressed in the references, especially in books, are somewhat repetitive. Fifthy, the references did not use appropriate pictures of the defects. Finally, many newer researches are scattered throughout the internet, and for this reason, these references are also used in this article.
