[QUOTE="Mohammad Khair, post: 155058, member: 12591"] its a mechanical bond and if we use a porcelain that have almost the same temperature as of the porcelain used for wash layer, then we will get better bond , cause each firing the wash layer will get more mature slowly and that will enhance bonding under shrinkage and vacuum. higher temp liner will not interact anymore after the first firing. i don't really need any liner the bond between my wash layer and the zircon framework is stronger than the bond between liner and the zircon framework, so clear liner will take a place for nothing, while i can use that space to enrich the color of choice with wash layer.
