Tips for stone furniture care
If natural stone furniture has a smooth surface, that makes the surface easier to wipe over. Therefore, a polished stone table can be cleaned more quickly than one with a coarse-ground surface. But care is required, as polished surfaces are highly sensitive to mechanical stresses. Even the tiniest grains of sand can make visible scratches on polished natural stone surfaces; therefore, remove even the slightest soiling immediately.
After cleaning, it is advisable to effective impregnate the furniture, especially with open-pored stone surfaces. This will re-emphasize the structure of the stone and provide a constant impregnation, meaning that soiling can penetrate less quickly.
Granite is a resistant hard stone comprising of feldspar, quartz and mica. Its colours range from light grey through to bluish, red and yellowish. Granite is used for flooring both indoors and outdoors, and also for kitchen worktops and washbasin shelves. Real granite is heat-resistant, cut-resistant and acid-resistant.
Nevertheless, caution is required. If spilled liquids are not absorbed immediately, they can penetrate into the material and leave unsightly stains.
As with other chalk stones (such as Jura or limestone), marble is a member of the acid-sensitive soft rock family.Real marble is a very old, dense crystalline rock, harder than limestone, but not nearly as hard as granite. Colours range from the purest white of Carrara marble through pink, grey and brown to black, depending on the kinds of metal oxides intercalated into it. Marble has to be carefully ground or polished to develop its full beauty. Its acid sensitivity makes it very susceptible to staining if not protected. Even the carbonic acid in mineral water can burn the surface. Strong alkalis can also alter the surface properties, such that the surfaces discolour and become dull. Therefore, we strongly recommend that you impregnate furniture made of marble.
