About Baltic Braun
Baltic Brown is instantly recognisable. The material shows a dark brown to black ground with striking round brown crystals that sit on the surface as though embedded. It is precisely this rapakivi appearance that makes the stone so characteristic and explains why Baltic Brown has been a classic for kitchens, stairs, floor surfaces, façades and solid dimension stone components for years. Compared with Tan Brown or Brown Antique it reads as less metallic and less cloudy, but markedly more ordered and unmistakable in its grain pattern.
The stone comes from Finland, from the Luumäki and Ylämaa area. Petrographically it is a rapakivi granite, that is, a particular granite variant with the typical rounded feldspar crystals. In the market, however, what counts above all is its role as a brown granite classic for internal and external use. Against reddish Finnish granites such as Rosso Balmoral, Baltic Brown is darker and earthier; against black granites, warmer and more striking.
Technically, Baltic Brown is load-bearing: bulk density is 2,630 kg/m³, compressive strength 187 MPa, flexural strength 10.7 MPa and water absorption 0.13 %. The stone therefore brings a good profile for worktops, façades, paving, stairs and floor surfaces. The low water absorption and the well-known Nordic external capability in particular make it a very reliable dimension stone for permanent applications.
The finishes available from stock are listed in the »Finishes« block further down. Brushed versions can emphasise the warm side of the material more strongly. At ROSSITTIS, Baltic Brown is available as a raw slab, in tiles, as tread and riser, window sill, skirting, façade panel and as a kitchen worktop.
The honest assessment: Baltic Brown is not a neutral stone. Its crystalline structure is strongly present and visibly shapes every surface. Anyone looking for exactly this classic brown granite look gets a load-bearing perennial. Anyone wanting a calmer dark brown without pronounced round crystals should rather look at Tan Brown or Brown Antique.

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.
Baltic Braun 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.
Geschliffen C120
Mattes Erscheinungsbild durch groben Schliff mit Körnung C120 — die ebene Oberfläche zeigt eine zurückhaltendere Farbintensität als poliert und kann sichtbare Schleifspuren tragen. Im Vergleich zur Politur pflegeintensiver, aber stilistisch ruhiger; bevorzugte Wahl für moderne Innenarchitektur mit reduzierter Reflexion.
Geflammt + 1 x gebürstet
Die Oberfläche wird durch Hitze aufgeraut und einmal gebürstet, um scharfkantige Mineralreste zu glätten und loses Material zu entfernen. Etwas sanftere Haptik als rein geflammt, weiterhin rutschhemmend, Farbe weniger intensiv als poliert. Standardwahl für Außenbereiche, Terrassen und stark beanspruchte Bodenflächen.
Care & fabrication
Baltic Brown should be sealed after installation, particularly on kitchen worktops and dark floor surfaces. Water absorption of 0.13 % is low, but a sealer nonetheless makes cleaning and care noticeably easier.
For cleaning and care, pH-neutral natural stone cleaners and a soft cloth are sufficient. On polished surfaces, water, limescale and grease residues should not be allowed to dry on.
Avoid abrasive pads and aggressive specialist cleaners not approved for natural stone. Oil, coffee and coloured foods should be removed promptly from worktops.
Outdoors, good drainage, regular cleaning and the appropriate finish are important. Technically the stone is robust, but visually, neglected textured surfaces quickly lose their clarity.
Frequently asked questions
Is Baltic Brown suitable for the kitchen?
Yes. Baltic Brown reaches 2,630 kg/m³ bulk density, 187 MPa compressive strength, 10.7 MPa flexural strength and 0.13 % water absorption. It is therefore well suited to kitchen worktops.
Which finishes are available for Baltic Brown?
The finishes available from stock are listed in the »Finishes« block on this page.
Where does Baltic Brown come from?
Baltic Brown comes from Finland, from the Luumäki and Ylämaa area. The stone is one of the classic Finnish granites with a rapakivi structure.
How do I clean Baltic Brown correctly?
For cleaning and care, pH-neutral natural stone cleaners and a soft cloth are sufficient. On polished dark surfaces in particular, grease and limescale residues should not be allowed to dry on.
Is Baltic Brown frost-resistant?
As a Finnish granite, Baltic Brown is well suited to external applications. The low water absorption of 0.13 % further supports its robust external suitability.
Baltic Brown or Tan Brown – which is better?
Tan Brown usually reads as calmer and more classically brown in its figure, Baltic Brown as more striking through its round rapakivi crystals. The decision comes down above all to the desired grain pattern.
