What is soluble salt technology (SST)?
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 color 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 color. For instance, our Diamond series is made with the use of SST. 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.
