(Soluble Salt Technology :- SST is an old and cheaper technology and is meant for tiles placed in low traffic areas. In this process, the yet unfired tile body is given a liquid colour screen-printing to create the design on the tile. It is called Soluble Salt Technology because soluble salt is used for giving the tile a particular pattern and colour. With this technology 2 – 2.7mm print are penetrated into the tile. Once the tiles have been fired and polished in order to create a glossy surface, approximately 0.7mm of the soluble print is shaved off, leaving a total print penetration of only 1 to 2 mm.)
