Labradorite Bianca Granite Image Labradorite Bianca Granite Polished Slab Image

Description: Labradorite Bianca granite is a light grey anorthosite with some single, blue iridescent areas and sometimes large black patches. This stone internationally may be nominated as a granite but in the area of application of the European Standard this stone must be nominated as an anorthosite. The veining and colour varies considerably and a small sample of Labradorite Bianca granite 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. Labradorite Bianca granite can be a very problematical granite to process and may need resining and glassfibre backing. Labradorite Bianca 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: Labradorite Bianca 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 possible that a sealant can be used on Labradorite Bianca granite however excessive attempts at sealing it could actually create a residue film build-up.

Block Sizes: It is believed there is more than one Labradorite Bianca quarry. 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: Labradorite Bianca granite is quarried near Ihosy, Ihorombe Region, Madagascar.

Synonyms: White Labradorite

Anorthosite:: A Precambrian, phaneritic, intrusive igneous rock characterized by a predominance of calcium-rich plagioclase feldspar (90-100%), and a minimal mafic component (0-10%). Pyroxene, ilmenite, magnetite, and olivine are the mafic minerals most commonly present. All anorthosites found on Earth consist of coarse crystals but some samples of the rock taken from the Moon are finely crystalline.

Labradorite:: This occurs in mafic igneous rocks and is the feldspar variety most common in basalt and gabbro. The uncommon anorthosite bodies are composed almost entirely of labradorite. It also is found in metamorphic amphibolites and as a detrital component of some sediments. Common mineral associates in igneous rocks include olivine, pyroxenes, amphiboles and magnetite.

Labradorescence:: A This is a side-effect of the molecular change which occurs in large crystal masses of anorthosite, producing an iridescent play of colors. This labradorescence, or schiller effect, is the result of light diffraction within the lamellar intergrowths - fine, adjacent layers of the separate materials (lamellae) comprising the whole rock phase - created when conditions do not allow for sufficient diffusion to the materials' equilibrium composition.
