Every veneer is one of a kind. The image shows the stone; your piece will look different.

The story

Black Rock is a slate from the Jaipur region in Rajasthan, India. Slate forms differently from marble: clay mud was pressed into stone over millions of years and layered into wafer-thin sheets – and it is exactly these layers that can be split. That is why slate has always been the thin stone: the roofs of half the continents are covered with it. We split it thinner still than any roofer ever has.

Black Rock is not polished. Its surface stays as it was split: matte, warm, with a tangible texture and no fingerprints.

Properties

Split, never polished. Matte, tactile and with a texture you could recognise with your eyes closed.

Care

Clean with the Stone Cleaner only. Do not polish: wax settles into the open surface and dries unevenly.
