Drag the slab to turn it, or use the arrow keys. Switching finish re-renders the surface — polished throws a hard specular, the abraded finishes open the surface up and knock the colour back.
Cement Ash is the dark end of the concrete family: deep charcoal, matt, with a fine even body and no visible aggregate to break it up. It is bought as an anchor, a dark island or a run of bar counters under light walls and pale joinery, and the flatness is the point, since a speckled dark surface would fight the same joinery. On dark material the finish decides more than it does on light: honed hides ordinary handling and wear markedly better than a polished black, which shows every wipe mark under a downlight. There is no pattern to align, so joints are purely a colour decision; keep them where they look deliberate, because on an unbroken charcoal body the seam is the only interruption on the surface. Made to order in slabs and cut-to-size, honed or polished, and listed for worktops, bar tops, commercial counters, vanities and splashbacks.
Marquina Black is the other dark colour on the line and the opposite intention — sharp white veining, meant to be looked at. Cement Ash carries no figure at all, which is why it takes the large uninterrupted areas.

Photographs
Cement Ash in the yard
We are photographing this material now. Until the shoot is done, the turning slab and the close-up below are renderings, and the honest answer to “what does it actually look like” is a sample in your hand.
No photographs yet. Ask us for the current slab and block photographs of Cement Ash — we shoot them on request, in the yard, with a scale in frame. A cut sample goes out by courier the same week.
Laid out
Cement Ash across a floor
A photograph shows one slab on a stand. This shows the stone tile after tile — where the pattern repeats, how far the tone drifts across a batch, and what the joint does to it. Every tile here is cut from a different part of the surface, the way material comes out of a real crate.
Indicative layout. Tone drift is deliberate — no two tiles from one batch match exactly, and a laid floor should never look like one photograph repeated.
In the room
Cement Ash against your wall colour
Nobody buys stone on a white background. Put Cement Ash on the floor, up the wall or across a worktop, set the colour it will actually sit against, and change the light — the same three questions every client asks on a site visit, answered before the sample ships.
A scene, not a render of your project: proportions are indicative and colour on a screen is never the colour in a room. Send us the drawings and we will lay the real slab sizes out against your setting-out.
Surface
Cement Ash, close up
The slab above turns; this is the same stone at the size it sits in your hand. Change the finish and it re-cuts.
Roughly a 130 mm span of Cement Ash, honed. A rendered preview, not a photograph of stock — ask for a physical sample before you specify.

Suitability depends on the finish, the thickness and the exposure. If you are specifying for external cladding, wet areas or heavy traffic, send us the detail and we will tell you what we would put in that position.

Asked about this stone
Cement Ash — questions buyers ask
Does a dark quartz show every fingerprint?
Any dark surface shows handling more than a light one, but honed hides it considerably better than a polished black does. On a working kitchen top or a bar counter, take it honed.
Is there any sparkle or aggregate in it?
No. The body is fine and even with no visible aggregate — closer to a flat charcoal than to a stone. If you want a visible crystalline sparkle, that is Super White at the other end of the line.
What does it pair with in the same kitchen?
It was made to anchor a light scheme: Pure White or Carrara Mist on the perimeter with Cement Ash on the island is the usual arrangement. All three come off the same made-to-order programme, so they can be produced and shipped together.
Can we have it in a textured matt rather than honed?
This quartz comes in two finishes only, honed and polished. Brushed, flamed and leathered belong to the natural stone side of the catalogue, not to this material.
