Bianco Carrara

Bianco Carrara is a calcareous marble from the Apuan Alps, quarried in the basins above the town of Carrara in Tuscany, where the quarries have been worked since Roman times. It is the marble of the Romans and of Michelangelo, and it remains the best-known white marble in the world: not for its rarity, but for its balance. Among the Apuan whites it is the most widely available, the most consistent in pattern and the most reasonable in cost.

Composition. It is almost pure calcite, calcium carbonate recrystallised over millennia by the pressure of the mountain. The grain is fine and even, described as 'saccharoidal' because a cut face resembles sugar: small, compact crystals that take a polish well and yield to the chisel.

Colour. The ground is a slightly cool white with a pearl-grey cast, which sets it apart from the warm, milky white of Calacatta and the pure white of Statuario. The trade grades 'C', 'CD' and 'Venato' denote progressively more veined grounds.

Veining. The veins are thin, diffuse and soft grey, drifting in clouds or threads: they fade into the ground rather than cutting across it. The result is a calm slab that reads as a single surface even along a long run of worktop.

Hardness. Like every marble it is a soft stone compared with granite and quartzite: a steel blade will scratch it, and acids dissolve the carbonate and leave a dull mark. It is nonetheless dense, with a medium porosity that a sealer keeps in check.

• Kitchen. This is the marble for whole kitchens: worktops, splashbacks and upstands from the same slab, without the stone stealing the scene. In a honed finish it forgives daily use.
• Bathroom. The classic: floor, wall cladding, basin top and bath in one stone. In bathrooms Carrara gives light without coldness and stands up to humidity when sealed and dried.
• Staircases. Treads and risers in Carrara have been laid for centuries: the fine grain resists footfall. On staircases we recommend a honed or brushed finish, less slippery than polished.
• Floors. In large slabs or modular tiles, it is the pale floor par excellence: for interior floors it can be polished to a mirror or left matt.
• Outdoors: with judgement. For thresholds, sills and sheltered cladding in a matt finish, yes: Carrara has centuries of history in the open air. For the worktops of outdoor kitchens, exposed to rain, frost and cooking fats, we recommend granite, quartzite or sintered stone instead: a marble polish does not last outdoors and acid rain dulls it.

The same slab speaks with a different voice depending on the finish. Polished: the mirror surface deepens the white and sharpens the vein, partly closes the pores but shows acid marks at once; it is the choice for bathrooms, floors and statement worktops. Honed (matt or satin): smooth but without reflection, the colour reads a little lighter and the marks of use all but disappear; it is the finish we recommend for a kitchen worktop used every day. Brushed: abrasive brushes leave a gently textured skin, soft under the hand, the most forgiving over time.

Bianco Carrara worktops are made 2 or 3 centimetres thick. At 2 cm the slab is lighter, suited to modular kitchens and bathroom furniture; at 3 cm it carries breakfast-bar overhangs, undermounted sinks and moulded edges carved from the solid. For a deep front of six, eight or twelve centimetres, a strip is bonded with a 45° mitred joint: the vein turns the corner and the eye reads a single piece of stone.

With a waterfall edge the side of the island runs to the floor in the same slab as the top, joined to it with the mitre. Book-matching, two consecutive slabs opened like the pages of a book so that the vein mirrors across the joint, gives a more subdued effect on Carrara than on Calacatta: the fine vein draws a delicate symmetry, better suited to a bathroom wall or a bedhead than to a dramatic island. Sinks carved from the solid, flush cut-outs and upstands from the same slab complete the workmanship.

A Carrara worktop is cleaned with warm water, neutral soap and a soft cloth, wiping up spills at once: lemon, vinegar, wine, tomato and fizzy drinks are a matter of minutes, not hours. No limescale removers, descalers or bathroom cleaners, which are acidic and etch the stone within seconds; no scouring pads. The worktop leaves the workshop already treated with an impregnating sealer, which slows the absorption of oil and coffee without altering the look of the stone: it is renewed as a rule once a year, when a drop of water no longer beads on the surface. A scratch or a dull mark is removed with fresh honing or polishing: marble renews itself. Every rule is in our guide to marble worktop care.

The three great Apuan whites come from the same mountain and differ in ground, vein and rarity. Calacatta has a warm white ground and broad grey or golden veins: it is the marble of islands made to be looked at and of book-matched walls, quarried in a handful of sites and among the most prized in the world. Statuario is the purest: a luminous, almost unblemished ground crossed by a few crisp grey veins, the sculptors' marble, rare and precious. Bianco Carrara is the most balanced: a pearl-grey ground, fine diffuse veining, wide availability and a more reasonable cost. If the stone is to be the protagonist, look at Calacatta and Statuario; for a kitchen or bathroom entirely in marble, with a serene, even light, Carrara is the answer.

Our guide to choosing marble for the kitchen widens the comparison to Nero Marquina, Botticino, travertine and Dekton.

In our workshop in Aprilia, on the Via Pontina between Rome and Latina, we have worked Carrara since 1976. Slabs are chosen one by one, in person or by video call, because the same trade name can hide whiter or greyer grounds. The 3D design shows how the slab will be cut before the saw touches it; cutting is computer-controlled, and hand finishing closes edges, sinks and joints. The site survey and quotation are free in Rome, Latina and throughout Lazio; installation is by our own team, and we deliver and install abroad as well, as on our Dubai project.
