Revolution

Geologically this is a quartzite — a metamorphic rock formed from original quartz-bearing sandstones through the action of high pressure and temperature. During the metamorphism the original quartz sand grains fused with one another under pressure and temperature and were reformed into a dense, crystalline quartzite composite. The intense wine-red to purple ground tint results from iron-oxide mineral components in a particularly concentrated enrichment, combined with manganese-bearing components that give the colouring its characteristic purple undertone. The flowing, wave-like white veining arises from secondary calcitic mineralisations with quartzitic proportions, which cemented the dense red parent stone in tectonic zones of weakness during or after the metamorphic history. The dark black-anthracite accent bands result from organic, carbon-bearing or manganese-iron mineral layerings from the original sandstone sediment, which were plastically deformed during the metamorphism. This complex history of mineralisation produces the unique three-component slab pattern of a wine-red ground, white wave veins and dark accents.

Visually, Revolution is characterised by an exceptionally theatrical, almost stormily painterly material signature. The powerfully wine-red to burgundy and purple ground tint is run through by dramatically flowing, wave-like white calcite veining, which moves across the slab pattern like successive waves or petrified movements — hence the marketing name “Wave” in some trade names. Dark black-anthracite accent bands supplement the material signature with additional passages of contrast and create an outspokenly lively, almost stormily dramatic slab appearance. Slab variation is considerable and an essential feature of the stone. With book-matched laying — the mirrored laying of adjacent slabs — particularly impressive, almost surreal-looking symmetrical large-scale patterns arise, with the full dramatic effect of the three-colour composition.

Technically, Revolution is, like all genuine quartzites, one of the most robust natural dimension stones there is: high compressive strength (typically between 200 and 250 MPa for pure quartzites), low water absorption (typically below 0.3 %), high hardness (Mohs hardness 7 for pure quartz), complete frost and acid resistance. Quantitative data sheets are only available to a limited extent for this specific variety; the general properties of Brazilian premium quartzites are, however, well documented. Quartzites are insensitive to acid from lemon juice, vinegar, wine, cola and all household acids — a central advantage over marbles and limestones. This combination of properties qualifies Revolution without restriction for intensively used kitchen worktops and prestigious interior and exterior applications.

In interior fit-out, Revolution is a statement material par excellence for the highest design demands and exclusive architecture. Classic applications are kitchen worktops in designer kitchens, accent walls in living rooms, hotel lobbies and entrance areas, bar counters and counter fronts, bathroom accent walls behind free-standing baths, table and console tops as statement furniture and fireplace surrounds with a dramatic effect. The powerfully wine-red to purple tonality with its flowing white wave vein drawings and dark accents harmonises particularly with dark timber in walnut, mahogany or oak, with brass, bronze and gold accents, with a reduced black and with a clear white. Revolution is a visual soloist of the highest expressive power — it works most strongly in restrained, refined surroundings in which it may function as the undisputed centre of the composition. Outdoors it finds use as a façade accent, entrance cladding and prestigious paving in high-grade exterior installations.
