LAMINAM® Pietra Piasentina Grigio

LAMINAM® Pietra Piasentina Grigio is a large-format porcelain slab from the Italian premium manufacturer Laminam, from the natural-stone-based IN-SIDE collection. The slab shows a medium grey dimension stone ground tone with characteristic fine white calcite veins and a subtle sedimentary depth structure – stylistically a precise quotation of the famous Friulian Pietra Piasentina dimension stone from the province of Udine. At ROSSITTIS we work Pietra Piasentina Grigio into heat- and acid-resistant kitchen worktops, islands, interior floors, stairs, wall cladding, bathroom fit-outs, external floor coverings, pool surrounds and back-ventilated façade systems with a classic Italian dimension stone effect.

Sinterkeramische Großtafel (Sintered Stone) der italienischen Premium-Marke Laminam (System-Gruppe, Fiorano Modenese) aus der natursteinbasierten „IN-SIDE"-Kollektion – kein gewachsener Naturstein, kein Quarzkomposit und kein klassisches Porzellan. Variante „Pietra Piasentina Grigio" als gestalterisches Zitat des berühmten friaulischen Pietra-Piasentina-Naturwerksteins. Wichtige Korrektur: Das Naturstein-Vorbild Pietra Piasentina stammt aus Torreano in der Provinz Udine in der Region Friaul-Julisch Venetien (Nord-Ost-Italien) – NICHT aus Piacenza in Emilia-Romagna. Petrographisch ist das Vorbild eine sedimentäre Karbonat-Brekzie aus der Eozän-Formation. Die Sinterkeramik ist vollständig mineralisch durchgesintert, hitzefest, säurefest, UV-stabil und außentauglich.

About LAMINAM® Pietra Piasentina Grigio

Background. Laminam® is the Italian premium brand for large-format porcelain slabs, founded in 2001 in Fiorano Modenese (province of Modena) as a subsidiary of the System group. The “IN-SIDE” collection within the Laminam programme is the manufacturer's natural-stone-based dimension stone line – with precise quotations of classic Italian natural stones such as Pietra di Cardoso, Pietra di Savoia, Otta phyllite and – within this family – Pietra Piasentina. “Pietra Piasentina Grigio” is the medium grey tonal variant with a fine dimension stone feel.

The natural stone model Pietra Piasentina. Pietra Piasentina is one of the most important and oldest Friulian dimension stones. The deposits lie around Torreano in the province of Udine in the region of Friuli Venezia Giulia (Italian “Friuli-Venezia Giulia”), north-eastern Italy – not to be confused with the city of Piacenza in Emilia-Romagna. Petrographically it is a sedimentary carbonate breccia from the Eocene formation – a dimension stone with characteristic whitish-grey calcite clasts in a medium grey calcite matrix. Pietra Piasentina has been used in Friulian architecture since antiquity for floor coverings, wall cladding, façades and dimension stone components and is one of the most iconic regional dimension stone grades in Italy.

Material composition and manufacture of the porcelain. 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 mould in a patented pressing process, provided with decorated pigment layers for the surface look 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, sintered-through slab with no resin content. This yields decisive technical advantages over engineered quartz: water absorption below 0.1 %, very high heat resistance (hot pots can be set down directly), full UV resistance and thus suitability for external use, frost resistance and almost complete acid resistance.

The Pietra Piasentina Grigio variant. The ground tone is a calm medium grey with subtle warm underlays, which appears markedly warmer than cool anthracite-coloured grades. Across the surface runs the defining design characteristic: characteristic fine whitish calcite veins in irregular, often diagonally running lines that quote the dimension stone model precisely. The slab also shows a subtle sedimentary depth structure with fine layer lines and occasional lighter areas of clast texture. From a middle distance the surface reads as a calm grey dimension stone image with a classic Italian natural stone feel; close up you discover the fine pigmented depth of the vein courses.

Formats and thicknesses. Laminam supplies the Pietra Piasentina slabs in several large formats: 1,200 × 3,000 mm and 1,620 × 3,240 mm in the thicknesses Laminam 5 (5 mm), Laminam 5+ (5.5 mm), Laminam 12+ (12 mm) and Laminam 20+ (20 mm). The thinner thicknesses are particularly suited to wall cladding, furniture fronts and façades, while the 12+ and 20+ slabs are standard for interior floors, external floor coverings and kitchen worktops. ROSSITTIS carries Pietra Piasentina Grigio in 12 and 20 mm thickness.

Thermal and chemical properties. Unlike engineered quartz, there is no polyester resin here – which removes the typical weaknesses: Pietra Piasentina Grigio is heat-resistant (hot pots can be set down directly, the slab is unaffected well beyond 200 °C), almost completely acid-resistant (wine, lemon, tomato, vinegar leave no traces) and fully UV-stable (suitable for external use). Frost and weather resistance are given. Water absorption: almost zero (below 0.1 %, as is typical for porcelain).

ROSSITTIS range. The surface finishes currently in stock are listed in the »Finishes« block further down. From the slabs we fabricate kitchen worktops, islands, bar counters, buffet and furniture tops, wall cladding, bathroom fit-outs (vanity units, wall and floor applications, showers with proper waterproofing), window sills, skirtings, interior floors in large format or tile format, external floor coverings, pool surrounds, stairs with treads and risers and back-ventilated façade systems.

Comparison. Within the Laminam IN-SIDE collection, Pietra Piasentina Grigio positions itself as the medium grey, classically Friulian dimension stone grade. Related natural-stone-based lines are Pietra di Cardoso (a Tuscan dimension stone), Pietra di Savoia (Piedmont, sandstone-oriented), Otta phyllite (Norwegian, with actinolite stars) and Ardesia (slate-oriented). Compared with genuine Pietra Piasentina natural stone, the porcelain variant remains predictable and acid-resistant – the natural dimension stone appears geologically more authentic with individual batch variation, but it is acid-sensitive (calcitic) and requires sealing. In competitive terms, among other porcelain brands, Neolith Piasentina, Optimum Surfaces, CTX BasicKeramik (the Atlantis line) and Caesarstone Lioli offer similar Pietra Piasentina dimension stone grades.

Honest assessment. Pietra Piasentina Grigio is the ideal choice for any application calling for a classic Italian medium grey dimension stone feel with characteristic calcite veining and full technical resilience. The surface finishes currently in stock are listed in the »Finishes« block further down. Anyone looking for stronger geological movement should switch to more dramatic marble-look grades such as Calacatta or Statuario; anyone who prefers genuine Pietra Piasentina authenticity should reach for the Friulian natural dimension stone and accept the higher willingness to care for it.

Finishes

LAMINAM® Pietra Piasentina Grigio is available in a range of finishes. The finish affects appearance, feel and the care it needs.

Naturale matt

Standardoberfläche im matten Keramik-Segment — die Originaloberfläche nach dem Brennen. Plan in der Anmutung, aber haptisch etwas rauer als poliert. Pflegeleicht, kratzunempfindlich und fleckenresistent — die alltagstauglichste Keramik-Veredelung für Küchenarbeitsplatten, Wandverkleidungen und Bodenflächen.

Fiammato geflammt

Unebenere und rauere Oberfläche, deren Haptik an geflammten und gebürsteten Naturstein angelehnt ist, aber deutlich intensiver in der Farbwirkung. Durch das Brennen bleibt die Keramikoberfläche geschlossen und pflegeleicht. Eine charaktervolle Wahl für gestaltete Außenflächen, Stufen und Wandverkleidungen mit rustikaler Anmutung.

Care & fabrication

Cleaning. In everyday use, warm water, a soft cloth or a clean mop and a neutral to mildly alkaline pH cleaner are sufficient. Mild all-purpose cleaners, mild washing-up foam and all commercially available sanitary and kitchen cleaners without hydrofluoric acid (HF) are suitable. The porcelain is almost completely acid-resistant – even vinegar, citric and hydrochloric acid practically do not attack the slab. Take up spills promptly, because on the medium grey surface dried drops with dark pigment (coffee, red wine, black tea) can be left behind as visible veils; the material itself, however, is pore-free and therefore stain-proof.

Do not use. Hydrofluoric acid (HF) and fluoride-containing cleaners are the only class of substance that can genuinely attack porcelain – they occur practically only in industrial glass and stone cleaners and are not relevant in the household.

Sealing. Not required – porcelain is dense and pore-free in itself, and water absorption is below 0.1 %.

Naturale matt surface. The naturale matt surface reacts somewhat more sensitively to smear films and visible wiping streaks than a polished variant; isolated water drops dry off less smoothly. We recommend prompt drying off with a soft microfibre cloth.

The surface finishes currently in stock are listed in the »Finishes« block further down. A classic external surface with high slip resistance – ideal for external floors, pool surrounds, stairs and areas with water contact.

Medium tonal values – care notes. On a medium grey porcelain, wiping marks remain less visible than on very dark or very bright slabs – a practically relevant advantage of this tonal class for heavily used kitchen worktops and entrance floors.

Kitchen and bathroom. In kitchen and bathroom use, technically almost unbeatable: hot pots can be set down directly for a short time, acids such as vinegar, wine, lemon and tomato leave no traces, and anti-limescale sprays and all commercially available sanitary cleaners are approved.

Floor and façade. One of the classic domains of this grade is external floor coverings, pool surrounds and façade systems. The flamed variant is slip-resistant and can therefore be used in certified fashion in areas with water contact.

Outdoors and frost. Fully suitable. The slab is UV-stable, frost- and weather-resistant and can be used as a back-ventilated façade panel, external wall cladding, pool surround and external floor covering.

Scratches and repair. Porcelain is very hard (around Mohs 7) and therefore considerably more scratch-resistant than most natural materials. Deeper damage cannot simply be re-polished – repair is carried out by replacing the affected workpiece.

Frequently asked questions

What kind of material is LAMINAM® Pietra Piasentina Grigio?

A large-format porcelain slab (sintered stone) from the Italian premium brand Laminam (System group, Modena), from the natural-stone-based IN-SIDE collection. Mineral raw materials (feldspar, quartz, clay minerals, pigments) are compacted without polymer binders in a pressing process and sintered at over 1,200 °C in a tunnel kiln. Stylistically the “Pietra Piasentina Grigio” variant quotes the famous Friulian Pietra Piasentina natural dimension stone from the province of Udine.

What does the name “Pietra Piasentina” refer to?

Pietra Piasentina is one of the most important Friulian dimension stones – petrographically a sedimentary carbonate breccia from the Eocene formation. The deposits lie around Torreano in the province of Udine in the region of Friuli Venezia Giulia (north-eastern Italy). NOT to be confused with the city of Piacenza in Emilia-Romagna – the name “Piasentina” derives from a regional Friulian designation. Pietra Piasentina has been used in Friulian architecture since antiquity.

What exactly does Pietra Piasentina Grigio look like?

A calm medium grey with subtle warm underlays as the ground tone, crossed by characteristic fine whitish calcite veins in an irregular, often diagonally running distribution, complemented by a subtle sedimentary depth structure with fine layer lines. Stylistically a precise quotation of the Friulian Pietra Piasentina natural dimension stone.

What slab formats and thicknesses does Laminam offer for the Pietra Piasentina line?

Standard formats are 1,200 × 3,000 mm and 1,620 × 3,240 mm, in the thicknesses Laminam 5 (5 mm), Laminam 5+ (5.5 mm), Laminam 12+ (12 mm) and Laminam 20+ (20 mm). ROSSITTIS carries Pietra Piasentina Grigio in 12 and 20 mm thickness.

Is Pietra Piasentina Grigio suitable for external surfaces, façades and pool surrounds?

Yes, completely – that is one of the central fields of application for this grade, above all with the fiammato/flamed variant. Porcelain is UV-stable, frost- and weather-resistant and can be used as a back-ventilated façade panel, external wall cladding, pool surround and external floor covering.

Which cleaners may I use?

Permitted are warm water, all neutral, alkaline or mildly acidic cleaners, mild all-purpose cleaners and all commercially available sanitary and kitchen cleaners. The slab is almost completely acid-resistant. Out of the question are only hydrofluoric acid (HF) and fluoride-containing cleaners – these are not relevant in the household.

Pietra Piasentina Grigio or genuine Friulian Pietra Piasentina natural dimension stone?

Pietra Piasentina Grigio (porcelain) is more even, more predictable, acid-resistant and fully UV-stable – the rational choice for external applications, façades and heavily used interior surfaces with minimal care. Genuine Friulian Pietra Piasentina natural dimension stone appears geologically more authentic with individual batch variation and a natural dimension stone feel, but it is acid-sensitive (calcitic) and requires sealing.

Pietra Piasentina Grigio or other medium grey porcelain grades?

Within the porcelain market, Neolith Piasentina, Optimum Surfaces (e.g. Lotus Grey), CTX BasicKeramik (the Atlantis line, from the ABK Group) and Caesarstone Lioli offer similar Pietra Piasentina dimension stone grades, each with its own material interpretation. Within the Laminam IN-SIDE collection, Laminam Pietra Piasentina Grigio is the specifically Friulian, dimension-stone-oriented choice.
