SPECIAL TECHNIQUES 0FLINING FOR THE DISTINCTIVE CERAMIC COATINGS.

Research depends on the idea of access to distinctive glaze through the use the lining as an intermediary between body of ceramic and glaze. Whether porcelain was dry body or burning first, or covered with glaze. _ Especially lining has been prepared for this purpose with a coefficient of contraction is very small, applied over the surface of the ceramic body with a different coefficient of contraction, and then applied glaze over the lining. Because glaze stretch and contraction is different for each of the ceramic lining and body, this leads to different results depending on the case of ceramic body.( clay , biscuits or covered by glaze ). Set of experiments was conducted on Ceramic of clay , biscuits, and as well as ceramic glazed, as the ceramic lining was applied to surface in all cases, then applied glaze over the lining, and pass the product on a single stage of the fire. Differing results have been observed, Depending different nature of the object ceramic case, where the results were between glaze cracked and another intermittently, along withhomogenized glaze. The interpretation of the causes of all the results and discussed along with taking notes and recommendations was done.
