Appearance, shades and patinas
Natural, rough, very structured, irregular with a dark grey to black colour.
Sawn if the Crust is cut to a fixed size

Fixed size sawn crusts used for cladding or base stones are very decorative. Their dark grey to black colour and their pronounced natural contours contrast with other elements on the building facade such as the windows and metal structures.
Crusts can also be used to produce street furniture such as fountains, accesses to water features and gardens etc.
Variable thickness due to the rough structure, on average 10cm (in certain places 5cm and in others 15cm)
