Spectrolite Granite Image

Description: Spectrolite granite is a very coarse-grained, non-foliated, dark blue-black anorthosite of the Precambrian period with individual, sparkling spectrolite crystals ranging from 5 to 50 mm in size. 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. 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. Spectrolite 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: Spectrolite 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 Spectrolite granite however excessive attempts at sealing it could actually create a residue film build-up.

Block Sizes: This is a quarry yielding selectable, grades of granite 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: Spectrolite granite is quarried at Nuijama, Ylaemaa, Finland, near the Russian border. Quarried since 1962. Rough blocks are classified in two categories: premium quality blocks and so called mass blocks. The so called mass blocks are not shaped and might have some colour and/or crack defects.

Synonyms: Finlandia Blau Spektrolit, Finlandia Blue, Finnischer Labrador, Labradorfels, Spectrolit, Spectrolith, Spectrolite, Spektroliitti, Spektrolith, Spektrolyt, Spektrolyth.

Anorthosite: A phaneritic, intrusive igneous rock characterized by a predominance of plagioclase feldspar (90-100%), and a minimal mafic component (0-10%). Pyroxene, ilmenite, magnetite, and olivine are the mafic minerals most commonly present.

Mineral Composition: Average Plagioclase: 81%, Pyroxene: 10%, Quartz: 4%, Other: 5%
