About Brown Antique

Brown Antique belongs to those dark natural stones that generate warmth and depth at the same time. The material shows a dark brown to almost black overall pattern with metallically shimmering crystal zones and warm brown layers. This makes the stone appear luxurious without presenting itself as hard-black as Nero Assoluto. On kitchen worktops, stairs, wall surfaces and dark floor areas in particular, Brown Antique therefore works very well: present, high-quality and at the same time somewhat more domestic than a pure black tone.

Finishes

Brown Antique is available in a range of finishes. The finish affects appearance, feel and the care it needs.

Polished

Polishing is the most classic finish in the hard stone segment — a mirror-smooth, high-gloss surface with the highest possible colour intensity and maximum depth effect in the mineral structure. As an acid-resistant silicate stone, polished granite is easy to care for and the first choice for kitchen worktops, wall claddings and prestigious exposed surfaces.

Satin-honed

The satin surface is created by brushing, which selectively removes softer minerals and gives the surface a slight depth. A matte appearance with subtle light reflection and a warm feel to the touch. Easy to maintain, insensitive to scratches and suited to everyday use — a popular alternative to a polish in modern kitchens and living spaces.

Wengé-plus wen-pec®-plus

An intensified version of the wengé special finish, with more pronounced texturing and a stronger depth effect in its wood-like character. A design-led finish for statement wall claddings and decorative accent surfaces; technical details and availability on direct request.

Care & fabrication

Brown Antique should be sealed after installation, particularly on kitchen worktops and dark floors. The very low water absorption of 0.10–0.11 % is strong, but a sealer makes cleaning and maintenance easier still.

For cleaning and maintenance, pH-neutral natural stone cleaners, water and a soft microfibre cloth are sufficient. On polished dark surfaces, water and limescale marks should not be allowed to dry on.

Avoid strongly abrasive products and aggressive specialist chemistry not approved for natural stone. Coffee, oil, wine or coloured foods should be removed promptly from worktops, so that the deep dark effect is preserved.

Outdoors, regular cleaning, good drainage and a finish appropriate to the use matter more than aggressive deep cleaning. Frost is technically well manageable with this material.
