Matt
The porcelain tile was a very rough, matt faced tile with sort of pores on the surface. It has a different colour on the back of the tile. Kind of like a porcelain backed tile with some kind of glaze on the face. very matt as oppose to satin finnish
Jakarta is a double loaded porcelain which is why it has the appearance it does, I.E the top 2-3mm is the same colour as the surface and the bottom is a different colour.
It is made with two layers of porcelain that are pressed together and then fired.
