More than 30% and less than 90%, in particular more than 40% and less than 80%, and preferably more than 50% and less than 65% of the surface of the visible face is formed by pores with an average width of more than 0.1 mm and less than 1 mm, an average depth of more than 10 μm and less than 50 μm, and the average ratio of depth to width of the pores of more than 1:4 and less than 1:30.
