Description: Bianco Sardo granite is the Commercial name for a coarse-grained, light grey granite of the Carboniferous/Devonian period. This stone internationally may be nominated as a granite and in the area of application of the European Standard this stone must be nominated as a granite. 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. Bianco Sardo granite is suitable for both interior and exterior use futhermore is frost resistant and with a constant polish.
Products: Suitable for construction projects both commercial and domestic, prefabricated countertops/worktops, vanities, tiles, backsplashes, paving, fireplaces and memorials.
Surface Finish: Bianco Sardo granite 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 most unlikely that a sealant can be used on Bianco Sardo granite due to the tight grain formation, attempts at sealing it could actually create a residue film build-up.
Block Sizes: This is one of Europe's most well-known granites emanating from several quarries. There are several varieties, sorts and trade marks. For commercial projects it is important to ensure that blocks are selected from the same quarry.
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: Bianco Sardo granite is quarried near near Ala Dei Sardi, Azieri, Budduso, Sassari, Sardegna, Italy.
Synonyms: Bianco Sardegna, Blanc Sarde, Blanco Sardo, Sardo Bianco
Granite:: A coarse or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth's crust, forming by the cooling of magma (silicate melt) at depth. The principal constituent of granite is feldspar. Both plagioclase feldspar and alkali feldspar are usually abundant in it, and their relative abundance has provided the basis for granite classifications. In most granite, the ratio of the dominant to the subdominant feldspar is less than two. Rocks containing less than 20 percent quartz are almost never named granite, and rocks containing more than 20 percent (by volume) of dark, or ferromagnesian, minerals are also seldom called granite. The minor essential minerals of granite may include muscovite, biotite, amphibole, or pyroxene. Biotite may occur in granite of any type and is usually present, though sometimes in very small amounts.
