What dolomitic means in practice
Every marble is a carbonate and every carbonate responds to acid. The difference is speed. A calcite marble marks readily; a dolomitic one takes longer to show the same effect, because the magnesium in its structure makes it less soluble.
It is a real difference and a matter of degree, not a change of category. Nothing about a dolomitic marble makes it acid-proof, and the marble tile page carries the full account of the chemistry.
How it looks against a Carrara
Bianco Dolomiti is a Turkish stone: a clean white to very pale gray ground with soft gray veining that is low in contrast and fairly evenly spread.
Against a Carrara it reads whiter and quieter. A Carrara's ground carries more gray and its veining runs in distinct fine threads; a Bianco Dolomiti keeps the threads softer and the ground brighter, which is why it gets specified where somebody wants Carrara but whiter.
Polished and honed
This range splits between polished and honed, and on a stone this low in contrast the finish does most of the work of deciding how it reads.
Polished brightens the ground and gives the faint veining just enough definition to be seen. Honed takes the reflection away and leaves a soft, even, almost matte white that reads closer to a limestone. Since there is so little veining to begin with, the two finishes produce further apart results here than they would on a heavily veined marble.
Mosaics are most of this range
Mosaic sheets lead the product types here, ahead of field tile, with a waterjet piece alongside them.
A low contrast white is the ideal mosaic stone, and it comes from what cutting does to a pattern. Chop a heavily veined marble into small pieces and the veining becomes disconnected marks; chop a Bianco Dolomiti and it stays recognizably itself, because there was never a long line to break. Marble mosaics covers the sheets.
Shade variation on a white stone
The pieces here that publish a figure read medium, which on a stone this pale is more visible than the same figure would be on a dark one.
A pale ground shows a shift in tone that a busy or dark stone would absorb, so two lots of a white marble sitting side by side declare themselves. It is the practical argument for taking a whole surface from one lot.
Formats and thickness
12x24 and 12x12 lead the sizes with a 10x13 mosaic sheet, at 3/8 and 1/2 inch thick.
The half inch pieces are worth noting where this tile meets another floor, since half an inch stands higher than the 3/8 inch that most marble field tile uses and the difference has to be resolved at the threshold.
Where Bianco Dolomiti goes
A bathroom floor, a shower, a backsplash, a bright hall and the white half of a two color floor. It is the white marble for rooms that want the stone to be quiet.
White marble tile gathers every white marble in the catalog, and Carrara marble tile the stone it is most often compared with.
