Background. Laminam® is the Italian premium brand for porcelain large-format slabs, founded in 2001 in Fiorano Modenese (province of Modena) as a subsidiary of the System group. Laminam is one of the European pioneers of large-format porcelain. The "Diamond" collection within the Laminam programme line is the manufacturer's most dramatic marble-look line – with the highest-quality natural marble quotations and with the special "Polished Starlit" polish variant, which creates a luminous star effect on the surface through incorporated sparkling elements. "Calacatta Black" is the black tonal variant within the Diamond family – stylistically an allusion to the rare black Calacatta natural marble with powerful white veining.
Material structure and manufacture. A Laminam slab consists of around 100 % mineral raw materials – feldspar, quartz, clay minerals and pigments – without polymer binders. The mixture is compacted in a patented pressing process in a mould, provided with decorated pigment layers for the surface appearance (multi-layer printing for the depth effect of the veins) and then sintered at temperatures above 1,200 °C in a tunnel kiln. In this sintering the mineral particles partly fuse into a closed crystalline mineral structure – the end product is a fully mineral, through-sintered slab with no resin content. From this follow decisive technical advantages over engineered quartz: water absorption below 0.1 %, very high heat resistance (hot pans can be set down directly), full UV resistance and therefore suitability for external use, frost resistance and almost complete acid resistance.
The Calacatta Black variant. The ground tone is a deep black-anthracite material black with subtle warm undertones – not the hard solid black, but a warmer-looking, mineral-deep black with fine lighter gradations for a sense of depth. Across the surface run characteristic powerful white calcite veins in a tree-like branched distribution – the veins vary from hair-fine to powerfully broad and create a dramatic dynamic of movement that comes very close to a real Calacatta marble. Stylistically, Calacatta Black is an allusion to the rare black Calacatta natural marble (also "Calacatta Black" or "Nero Calacatta") with powerful white veining – as a controllable, reproducible porcelain variant. The unidirectional veining can be composed into impressive V, X or quad patterns by bookmatch mirroring of adjacent slab pieces.
Formats and thicknesses. Laminam supplies the slabs in several large formats – the standard format is around 162 × 324 cm and 100 × 300 cm. The thicknesses are graded in 5, 6, 12 and 20 mm; the 5 and 6 mm slabs are particularly suited to wall claddings, furniture fronts, interior doors and façades, while the 12 and 20 mm slabs are standard for interior floors, external floor coverings and kitchen worktops.
Thermal and chemical properties. Unlike engineered quartz, there is no polyester resin here – so the typical weaknesses fall away: Calacatta Black is heat-proof (hot pans can be set down directly, the slab is unaffected well beyond 200 °C), almost completely acid-proof (wine, lemon, tomato, vinegar leave no traces) and fully UV-stable (suitable for external use). Frost and weather resistance are given. Water absorption: 0.1 % (typical of porcelain). Food-safe and antibacterial.
ROSSITTIS range. The surface finishes available from stock are listed in the »Finishes« block further down. From the slabs we fabricate statement kitchen worktops, islands, bar counters, buffet and furniture tops, prestige wall claddings with bookmatch mirroring, bathroom fit-outs (washstands, wall and floor applications, showers with proper waterproofing), window sills, skirtings, interior floors in large format or tile format, external floor coverings, pool surrounds and rear-ventilated façade systems.
Comparison. Within the Laminam Diamond marble-look family, Calacatta Black positions itself as the dark, dramatic tonal variant with an iconic black Calacatta character. Related Diamond grades include light Calacatta variants (white-grey veined) and other marble-look compositions. In competitive comparison with other porcelain brands, Neolith Calacatta Black, Optimum Surfaces Pietra Grey 086, Caesarstone Lioli and Dekton (Cosentino) offer similar dark marble-look grades, each with its own material interpretation. Compared with real black Calacatta natural marble (very rare and expensive), the porcelain variant is predictable and acid-proof – the natural marble appears geologically more authentic with individual batch variation, but is acid-sensitive (calcitic) and considerably higher in price. Within the Laminam portfolio the Diamond line is the most dramatic; calmer options are the concrete-look lines (Fokos), the dimension-stone-based lines (Pietra di Cardoso, Pietra di Savoia) and the solid-colour lines.
Honest assessment. Calacatta Black is the ideal choice for any application calling for a dramatically luxurious dark marble character with characteristic powerful white veining. The grade works particularly strongly as a statement kitchen island with bookmatch (one of the most iconic application images), as a prestige wall cladding with symmetrical vein mirroring, as a bathroom washstand in luxurious master-bath concepts and as an outdoor kitchen surface. Anyone looking for a calm, even dimension-stone effect should switch to concrete-look grades such as Laminam Fokos or to classic dark solid-colour slabs; anyone who prefers authentic black Calacatta natural marble with geological authenticity should accept the higher care requirement and the acid sensitivity of the marble material – as well as the considerably higher price level.
