Bianco Sivec A3 is the livelier, somewhat more strongly figured trade quality of the North Macedonian Sivec marble. At ROSSITTIS it is used for bathrooms, stairs, walls and bespoke interiors with more movement.
Bianco Sivec A3 belongs to the same marble family as the very calm A1-A2 selections, but deliberately shows more figure and a slight tonal movement. Its ground tone stays white to off-white, complemented by finer grey, slightly cream-coloured or cloudy nuances. This makes the stone read as less austere and homogeneous than A1-A2, and somewhat livelier and more natural. In bathrooms, on stairs, on wall surfaces and in interiors in particular, that can be very interesting in design terms where a white marble with a little more character is wanted.
The stone likewise comes from the Prilep area in North Macedonia and is the more animated trade quality within the Sivec family. Compared with A1-A2, A3 is less uncompromisingly white, but frequently also more relaxed in appearance. Against Carrara the stone usually stays denser and whiter; against Lasa or Pentelico, somewhat more technical. That makes it a good choice for projects that want the Sivec quality but do not need maximum homogeneity.
Technically, Bianco Sivec A3 lies at around 2,840 kg/m³ bulk density, about 0.35 % water absorption, approximately 141.0 MPa compressive strength and around 9.6 MPa flexural strength. Frost resistance is documented, but the polish does not last permanently outdoors. For stairs, wall claddings, vanity tops and carefully planned work surfaces this is well usable. At the same time it remains an acid-sensitive marble that works entirely carefree neither in the kitchen nor on heavily loaded floors.
The finishes currently available from stock are listed in the »Finishes« block further down this page. At ROSSITTIS, Bianco Sivec A3 is available as a raw slab, as tiles, as vanity tops, kitchen worktops, treads and risers, window sills, skirtings and for other bespoke internal components.
The frank assessment: Bianco Sivec A3 is not a maximally homogeneous premium white marble and not a hard rock for carefree use. Its strength lies in a pale marble quality with a little more life in the surface. Where precisely that balance is wanted, it is very coherent.

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.
Bianco Sivec A3 is available in a range of finishes. The finish affects appearance, feel and the care it needs.
Poliert
Politur ist die klassischste Veredelung für Marmor und Kalkstein — eine glänzende Oberfläche mit höchstmöglicher Farbintensität und ausgeprägter Tiefenwirkung der Aderung. Je nach mineralischer Zusammensetzung kann die Wirkung stellenweise mattglänzend sein. Säureempfindlich — Wein, Zitrone und Essig hinterlassen Ätzspuren bei längerer Einwirkung.
Care & fabrication
Bianco Sivec A3 should be sealed carefully on kitchen, bathroom and stair surfaces. That makes cleaning and care easier and reduces the uptake of water, oil and staining agents.
For cleaning and care, pH-neutral natural stone cleaners, a soft cloth and as little standing water as possible are suitable. Acidic cleaners, descalers and aggressive kitchen chemicals attack the marble and are unsuitable.
In the kitchen, lemon juice, vinegar, wine and coffee should not be left on the surface for long. On pale polished marbles, stains and etch marks become visually apparent quickly.
For external applications, restraint makes sense: the stone is frost-resistant, but the polish does not last permanently outdoors. Its strength lies clearly in high-grade internal use.
Frequently asked questions
Is Bianco Sivec A3 suitable for a kitchen?
Yes, but only with a conscious understanding of marble. At around 2,840 kg/m³ bulk density, about 0.35 % water absorption and 141.0 MPa compressive strength, Bianco Sivec A3 is solid, but it remains acid-sensitive.
What finishes are available in Bianco Sivec A3?
The finishes currently available from stock are listed in the »Finishes« block on this page.
Where does Bianco Sivec A3 come from?
Bianco Sivec A3 comes from the Prilep area in North Macedonia. A3 denotes the somewhat livelier trade quality within the Sivec family.
How do I clean and care for Bianco Sivec A3?
For cleaning and care you should use pH-neutral natural stone cleaners and a good sealer. Acidic products are unsuitable.
Is Bianco Sivec A3 suitable for external use?
Only with restraint and on a project-specific basis. The stone is frost-resistant, but the polish does not last outdoors, which is why its strength lies clearly indoors.
Bianco Sivec A3 or A1-A2?
A1-A2 reads as whiter and more homogeneous, A3 as somewhat livelier and more natural. Technically the two lie close together; in design terms A3 is the more animated variant.
