A stereo ceramic granite and marble has a stereo pattern composed of more than two non-transparent silicate color masses containing more than 20% non-vitrified state composition. As seen from its vertical section, it has the characteristics that wherein both vertical sectional edges of at least four mutually contacting color masses are essentially parallel to the extension lines of the boundary lines of the other color masses from within 3 mm beginning form the surface of the product and form an angle of 10 DEG to 170 DEG with the surface plane of the product, the deviation error of parallelism not exceeding 40 DEG , and this kind of pattern exists in the product at more than four places. |
