Leaf Rust is a marble with a water based finish that gives to the material a better lightness and clearness. The superficial treatment of this marble consist in a superficial scratching that gives to the Leaf Rust a precious and particular texture. It is a natural material, the slabs are different from one another, from block to block, from quarry to quarry, in particular they are differentiated by tone, color, intrusions, stains and veinings. Each slab should therefore be considered as a single piece. The material can be modified by acquiring an aspect that makes it more valuable showing signs of aging.
