Giallo Siena Nuvolato Etrusco Limestone Image

Description: Giallo Siena Nuvolato Etrusco Limestone is fined-grained, resembling a breccia that is pearl grey, golden yellow with blue-grey veins, a vivid decorated limestone (beginning metamorphism, grading to marble). This stone internationally may be nominated as a marble but in the area of application of the European Standard this stone must be nominated as a limestone. The veining and colour varies considerably and a small sample of Giallo Siena Nuvolato Etrusco Limestone may not be representative of the whole slab therefore swatch samples must be approved for large projects to ensure that the blocks are all extracted from the same quarry face for matching purposes. During the polishing process a clear epoxy resin filler may be used to fill any micro fissures or tiny pitting however this does not affect the integrity of the stone, it merely provides an even smoother surface finish. Giallo Siena Nuvolato Etrusco Limestone is ideal for both interior and exterior use however polish is only constant inside.

Products: Suitable for construction projects both commercial and domestic, prefabricated countertops/worktops, vanities, tiles, backsplashes, paving, fireplaces and memorials.

Surface Finish: Giallo Siena Nuvolato Etrusco Limestone looks best with a gloss polished surface but is also available as honed, leather/satin, river-washed/antique, thermal/flamed, brushed and sandblast finish.

Sealing: Test with a small sample. It is possible that a sealant can be used on Giallo Siena Nuvolato Etrusco Limestone however excessive attempts at sealing it could actually create a residue film build-up.

Block Sizes: This is a quarry yielding selectable, grades of limestone with blocks suitable for gangsaw size down to economical tile-sized blocks. For commercial projects it is important to ensure that blocks are selected from the same quarry face.

Rough blocks are usually exported by Break Bulk however intermodal containerisation is available at extra cost. Finished products are packed into sea-worthy wooden crates and loaded into containers.

Quarry Location: Giallo Siena Nuvolato Etrusco Limestone is quarried near Colle di Val d'Elsa, Sovicille, Provincia di Siena, Tuscany, Italy.

Synonyms: Blue Dorato, Breddolato

Limestone: A sedimentary rock wholly or in large part composed of calcium carbonate. The primary source of the calcite is usually marine organisms, which settle out of the water column and are deposited on the ocean floors as pelagic ooze (but see lysocline for information on calcite dissolution). Secondary calcite may also be deposited in super-saturated meteoric waters, as is evidenced by the creation of stalagmites and stalactites. It is ordinarily white but may be coloured by impurities, iron oxide making it brown, yellow, or red and carbon making it blue, black, or grey. The texture varies from coarse to fine. Most limestones are formed by the deposition and consolidation of the skeletons of marine invertebrates; a few originate in chemical precipitation from solution. Limestone deposits are frequently of great thickness.
