A mosaic made of alternate honed and scratched Kaesar Brown horizontal slats of the same dimensions, both 10 mm. calibrated and grid-mounted in 29.8 per 29.8 modules. The constant rhythm, more or less evident according to the marble colour adopted, is generated by the differences in the surface finishing. There will be a more evident play of contrasts when darker materials are used, while lighter materials will produce a more homogeneous effect. However, the overall look of the surface will still be smooth and delicate, as the mild roughness of the graffiato will not determine a coarse overall tactile effect.
