Description:
Porphyry Cubes 4/6
They are distinguished, according to the edge length (in cm), in the following types: 4/6 - 6/8 - 8/10 - 10/12 - 12/14. Every type includes only elements with edges with length ranging between the above-cited limits (at the most 1 cm more or less). The various edges of the small cube do not have to be necessarily equal, and the various faces do not have to be necessarily orthogonal to one another. The upper surface of the cube will have to be natural, right as it gets out of the mine, and with no excessive roughness. The four side-faces are obtained by hydraulic cleft (they are not sawed) and then they have a rougher and slightly acute surface. |
