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.
