01 / Geological family

Origin and composition

Geological family
Sedimentary
Origin and composition
fine-to-medium arkosic sandstone with quartz and feldspar
Origin
Villamayor de Armuña, Salamanca, Spain
Appearance and identification
pale and ochre tones with a golden patina

Sedimentary rocks form through accumulation, compaction and cementation of sediments, or precipitation of minerals. Sandstones, limestones and travertines belong to this broad family but have different compositions and structures. Visible bedding can influence slab design and cutting direction. Selection calls for attention to pores, cement, discontinuities and the specific product rather than assuming that every member behaves like one familiar stone.

04 / Technical interpretation

What to ask your supplier

Patina evolves; freshly cut stone and old fabric will not automatically match.

05 / Care and maintenance

Care and maintenance

Remove dust and grit with soft tools, wash with a compatible neutral cleaner, then rinse and dry. Identify composition before using stain or scale removers: carbonate stones are acid-sensitive. Test every treatment in an inconspicuous area. An impregnator can reduce absorption but does not make a material waterproof or stain-proof.
