About Black Sao Brasil
Black Sao Brasil belongs to the group of black hard rocks that convince through density and reliability. The surface is deep black, largely directionless and medium-grained, without decorative gold or silver flecks. This makes the stone read as calm and technically clean across large surfaces. For facades, stairs, kitchens and heavily frequented floor areas in particular, this is a very usable combination of dark effect and matter-of-factness.
The material comes from Espírito Santo in Brazil and is petrographically a gabbro. On the market it is traded as a granite, like many black gabbros. That is not a simplification made out of convenience but corresponds to practical use: customers are looking for a black granite for indoors and outdoors, and Black Sao Brasil works precisely in that role. Compared with Nero Assoluto it stays somewhat more mineral; against Black Antique it is markedly calmer and less colourful. Anyone seeking a matter-of-fact black stone with clear technical suitability is in the right place here.
The characteristic values are hard-wearing: around 2,950 kg/m³ bulk density, around 0.33 % water absorption, around 129 MPa compressive strength, around 143.6 MPa compressive strength after frost and around 25.7 MPa flexural strength. Added to this is normal acid resistance within the hard rock range. This shows a material that is not only visually dark but also to be taken seriously structurally. Its good frost performance in particular makes Black Sao Brasil interesting for external use, provided the detailed design is executed cleanly.
The finishes currently available from stock are listed in the »Finishes« block further down this page. At ROSSITTIS, Black Sao Brasil is available as a raw slab, in tiles, as treads and risers, window sills, skirtings, kitchen worktops and for facade and external paving.
The frank assessment: Black Sao Brasil is not a glamorous effect stone. Its strength lies in dark precision, high density and sound external capability. Anyone looking for exactly that gets a very convincing black granite type. Anyone expecting maximum homogeneity or decorative brilliance should compare other black materials.

Technical data
Guide values for the stone type, taken from manufacturer and test reports. Natural stone is a natural product — individual batches and slabs can differ. For critical applications, request slab-specific test data.
Black Sao Brasil is available in a range of finishes. The finish affects appearance, feel and the care it needs.
Poliert
Politur ist die klassischste Veredelung im Hartgesteinsegment — eine spiegelglatte, hochglänzende Oberfläche mit höchstmöglicher Farbintensität und maximaler Tiefenwirkung der Mineralstruktur. Als säurebeständiges Silikatgestein ist polierter Granit pflegeleicht und für Küchenarbeitsplatten, Wandverkleidungen und repräsentative Sichtflächen erste Wahl.
Care & fabrication
Black Sao Brasil should be sealed on worktops and in wet areas. That makes cleaning and care easier and keeps the black surface more even, even though at around 0.33 % water absorption the stone is already relatively dense.
For cleaning and care, pH-neutral natural stone cleaners, clear water and a microfibre cloth are sufficient. On polished surfaces, water residues and limescale films should not be allowed to dry on, because they become visible more quickly on black.
Avoid abrasive pads, acidic specialist cleaners without natural stone approval and unnecessarily aggressive degreasers. Oil, coffee or red wine should be removed promptly in the kitchen.
Outdoors, a slip-resistant finish, good drainage and professional laying are decisive. Black Sao Brasil then brings its frost resistance and durability cleanly into play.
Frequently asked questions
Is Black Sao Brasil suitable for a kitchen?
Yes. With around 2,950 kg/m³ bulk density, around 0.33 % water absorption, 129 MPa compressive strength and 25.7 MPa flexural strength, Black Sao Brasil is a hard-wearing material for kitchen worktops.
What finishes are available in Black Sao Brasil?
The finishes currently available from stock are listed in the »Finishes« block on this page.
Where does Black Sao Brasil come from?
Black Sao Brasil comes from Espírito Santo in Brazil. Petrographically it is a gabbro, which is carried in the trade as a black granite.
How do I clean and care for Black Sao Brasil?
For cleaning and care, pH-neutral natural stone cleaners and a soft cloth are sufficient. Sealing is advisable for kitchens, bathrooms and dark floor areas.
Is Black Sao Brasil frost-resistant?
Yes. The stone is frost-resistant and achieves around 143.6 MPa compressive strength after frost. With the right choice of finish it is therefore well suited to external applications.
Black Sao Brasil or Nero Assoluto?
Nero Assoluto reads as more homogeneous and more closed black. Black Sao Brasil is likewise calm, but shows somewhat more mineral presence and a technical, very hard-wearing profile.
