Abstract: It is difficult to clean the sediments on the surface of ceramic relics, which not only affects the beauty of porcelains, but also easily causes erosion and other damages, thus arousing widespread concern of Chinese researchers. In this paper, the formation mechanism of "silver glaze" on the surface of unearthed potteries, the removal method of surface deposited films, the composition analysis, formation reasons and cleaning methods of surface deposits of unearthed porcelain were systematically combed and summarized, which laid a foundation for further study on the formation mechanism, protection measures and cleaning methods of the surface deposits of potteries and porcelains. In addition, the unsolved problems and those that can be further studied are also discussed.
Key words: ceramic protection; sediments; effluent porcelain; unearthed porcelain
