THE BISQUE TILES IN PORCELANIC PASTE: PORCELANIC STOWARE BY DOUBLE FIRING

TERRA CUITA supplies the goods being fired as to be strong enough to be transported, as well as to support hard decorations without presenting damages by fracture, being still porous.

Later the email procedure is done with the convenient glazes to a higher temperature and, at the second firing, that must be upper to 1170 ºC, the tile suffers an reduction over 7 %.

At this second firing the tile becomes “porcelanic”, the porosity disappears, in the way that the tile does not absorbs the water and so it resists the freezing.
