The Curated European Material Matrix

Roman Classico & Navona Travertine

Sourced directly from Barco Quarries, Tivoli, Italy

Precipitated from geothermal calcium carbonate springs over millennial cycles, Roman Travertine remains the quintessential foundation of European classical and minimalist monuments. In our atelier, we work with cross-cut slabs where internal cavitation produces natural acoustic dampening.

Mineral Classification	Sedimentary Calcium Carbonate (CaCO3)
Dry Bulk Density	2,450 – 2,520 kg/m³
Flexural Strength	11.4 MPa (EN 12372)
Standard Atelier Finish	Micro-honed 400-grit, unfilled surface pores
Typical Application	Monolithic portal frames, flooring, bathtubs

Hand-Patinated Architectural Bronze

Forged & Finished in Brescia, Lombardy

Our architectural bronze is an intentional alloy of copper, zinc, and tin, cold-treated with proprietary sulfur solutions to induce rich chiaroscuro patinas ranging from warm bistre to dark walnut. Unlacquered wax allows the metal to record the life of the home.

Alloy Composition	Cu 88% • Sn 10% • Zn 2% (Architectural CuSn10)
Tensile Strength	310 – 380 MPa
Thermal Conductivity	50 W/(m·K)
Surface Protection	Cold organic carnauba and beeswax seal
Typical Application	Pivoting entrance gates, bespoke taps, reveal trims

Belgian Blue Limestone (Pierre Bleue)

Quarried in Soignies, Wallonia, Belgium

Over 340 million years old, Belgian Blue Stone contains micro-fossils of ancient marine crinoids. When hand-honed, its subtle charcoal depth provides a striking counterweight to warm travertine and pale linen drapery.

Petrographic Name	Encrinite Limestone
Water Absorption	0.22% (Highly frost and stain resistant)
Compressive Strength	155 MPa
Acoustic Character	Dense reflective dampening
Typical Application	Kitchen monolithic islands, outdoor courtyards

Smoked Black Forest Bog Oak

Harvested in Black Forest Riparian Zones, Germany

Submerged for centuries under anaerobic mineral riverbeds, our bog oak develops natural dark charcoal tannins without chemical dyes or artificial stains. Finished with cold-pressed natural plant oils.

Botanical Source	Quercus Robur (Aged Riparian Bog Submersion)
Moisture Equilibrium	8% – 10% climate-kilned
Acoustic Absorption	NRC 0.35 (Concealed micro-cavity backing)
Surface Oil	Organic linseed & matte tree-wax formulation
Typical Application	Full-height shadow-gap doors, library partitions
