About Clashach
Clashach is a versatile natural stone sourced from the United Kingdom, known for its subtle grey hue and fine-grained texture. The stone exhibits a subtle, almost translucent veining that adds depth without overpowering its understated elegance. Ideal for both interior and exterior applications, Clashach performs well in flooring, wall cladding, and countertop surfaces, especially when finished with a satin or polished sheen to highlight its natural grain. Marmi di Carrara supplies Clashach in ready‑to‑use blocks and 2–3 cm slabs, offering custom cut‑to‑size options and high‑resolution photographs of actual slabs before purchase, ensuring architects and designers receive accurate visual references for their projects.
Typically grey.

Finishes for Clashach
Polished
Mirror-like gloss that brings out colour and veining at full depth. The classic choice for walls, tops and interior floors; slippery when wet.
Honed
Smooth and matt, with a soft satin look. Hides small scratches and etching better than a polish and is safer underfoot.
Brushed
Worked with abrasive brushes for a slightly undulating, silky surface that follows the grain of the stone. Warm to the touch and easy to live with.
Care and maintenance
- Clean with water and a neutral detergent made for natural stone; rinse and dry.
- Avoid acids and descalers (vinegar, lemon, anti-limescale sprays): they etch calcite and dull a polished surface.
- Seal with an impregnating protector after laying and repeat when water no longer beads, typically every 1–3 years on tops.
- Wipe wine, coffee, oil and citrus juice straight away, especially on kitchen and vanity tops.
- A dulled or scratched surface can be re-honed or re-polished on site: the stone is the same through its whole thickness.
