Crusts or rock-faced stone

The stone is sawn mechanically by a gantry stone-block cutting machine, wire saw, or diamond wire for larger elements (rough-hewn blocks), or cut up with a diamond disc blade in the case of smaller elements.

Technical particularities

  • Colour:  Light grey with slight nuances scattered randomly over the entire surface, depending on the type of sawing.
  • The sawing leaves traces that appear on the stone’s surfaces in the forms of small (0.1 to 1 mm deep) parallel waves that follow the direction of the sawing by the gantry cutting machine or wire.  They are parallel but have a circumferential appearance if the sawing is done by a disc blade.
  • Minimum thickness, mechanical:  2 cm

Common uses

  • - Building stones
  • - Cladding panels
  • - Floor tiles
