MINERALS & METALS • ARCHIVAL SPECIMENS

Surfaces that mature with dignity.

We maintain a permanent collection of honest minerals, unsealed alloys, and slow-harvested timber. Every specimen is cataloged for structural density and patination behavior.
SPECIMEN 01

Raw Flamed Basalt

Volcanic extrusive rock with exceptional compressive strength and acoustic absorption. Split by hand along natural tectonic cleavage lines for exterior thresholds and wet room slabs.

Provenance Auvergne, France
Finish Diamond flamed, beeswax cured
Density 2,950 kg/m³
Application Cantilevers, entry portals
SPECIMEN 02

Silver Roman Travertine

Sedimentary limestone formed in geothermal hot springs. Left un-grouted with natural open pores to celebrate subterranean geology across massive monolithic kitchen altars.

Provenance Tivoli Basin, Italy
Finish Water-honed, open-pore
Density 2,440 kg/m³
Application Culinary islands, washbasins
SPECIMEN 03

Smoked Black Oak

Harvested from certified sustainable Bavarian reserves. Subjected to organic ammonia and vegetable-oil baths to pull the natural tannins into a velvety charcoal tone without synthetic stains.

Provenance Spessart, Germany
Finish Wire brushed, pure oil bath
Hardness 3.7 Brinell
Application Flush pivot doors, joinery
SPECIMEN 04
