Super White: complete guide
Super White is a Brazilian stone with a white-grey background and grey veining reminiscent of statuary marbles. It is often sold as quartzite, but in most cases it is a dolomitic marble, harder than an ordinary marble but less hard than a true quartzite.
History and origin
Quarried in Brazil, it has become established on the international market as a light veined stone for contemporary kitchens and bathrooms. The name 'quartzite' is widespread in the trade, but analyses and practical tests generally place it among the dolomitic marbles. Knowing its true nature helps to use it correctly and to anticipate how it will behave. Marmi di Carrara supplies it on request.
Look and veining
The background ranges from white to very light grey, with grey veining that is sometimes soft and sometimes bolder. Variability between slabs is considerable, with whiter areas and others more heavily patterned. Polished, it looks bright and deep, while with a satin or leather finish it takes on a softer appearance.
Technical properties (indicative)
| Classification | dolomitic marble (often called quartzite in the trade) |
|---|---|
| Density | approx. 2,800 kg/m³ (indicative) |

Recommended uses
Suitable for bathroom vanity tops, cladding, floors and even kitchen worktops, provided you accept that small signs of wear may appear over time. For heavily used kitchens a leather or satin finish is advisable, as it makes any dull patches less visible.
Care and maintenance
Clean with neutral detergents and wipe up citrus, wine and vinegar promptly. A water- and oil-repellent treatment limits staining, while anti-limescale and acidic products should be avoided.
Pairings
- walnut or thermally modified oak
- matt black metals or brass
- anthracite grey tiles or plaster
FAQ
Is Super White a quartzite or a marble?
Despite its trade name, it is mostly a dolomitic marble. A scratch test with a steel blade and a drop of acid on the back of the slab make it possible to check.
Is it suitable for the kitchen?
Yes, with some care: it performs better than a calcitic marble, but acids can leave marks on the polish. A satin or leather finish is the most practical choice.
How does it differ from Carrara marble?
Carrara is a calcitic marble, softer and more sensitive to acids; Super White has a greyer background and slightly greater hardness.
