Green Slate: complete guide
Green Slate is a Brazilian slate with a green colour and a fine, regular surface. It is chosen for floors and cladding with a natural tone, offering good value for money.
History and origin
It comes from Brazil, one of the world's leading slate producers, exported in large quantities for floors, cladding and roofing. The green variety is less common than the grey and black ones and is chosen to add a touch of natural colour. It is readily available as tiles and standard-format slabs. Marmi di Carrara supplies it on request.
Look and veining
The background is green, from sage to olive green, with a very fine grain and a fairly uniform appearance. Slight variations in tone and some lighter or oxidised nuances may be present. Natural riven gives a slightly irregular surface, while a honed finish is smooth and matt.

Care and maintenance
