Problems solved by technology

[0012] Another disadvantage is that, due to the plasticity of the raw ceramic material being extruded, the decorative glaze has difficulty penetrating into it and tends to remain on the surface of the material, thereby hindering the final grinding step in certain cases
[0013] Yet another disadvantage is that, due to the need to save ceramic material in the production of the articles, the articles need to be thinner and thinner, and the manipulation of these thin articles in their original plastic state is very problematic due to their tendency to deform spontaneously
