Please click on image to enlargen, this is an average sample only. Your monitor settings may affect appearance. 
Description: Sapphire Brown granite is a very coarse-grained, brown-red cordieritefels with big, brown-red feldspar phenocrysts and blue-grey quartz. 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 a cordieritefel. The veining and colour varies and a small sample of Sapphire Brown 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. 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. Sapphire Brown 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.
Premium Quality Slab Sizes 2 & 3cm
Standard Slab Sizes 2 & 3cm
Granite Countertops 2 & 3cm
Memorial/Monumental Slabs Calibrated Tiles: Standard sizes available are: 305 x 305 x 10 mm (12" x 12" x 3/8") More granite tile and production information. Surface Finish: Sapphire Brown 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 Sapphire Brown 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: Sapphire Brown granite is quarried near Kazipet, Andhra Pradesh, Western and Eastern Ghats, India. Synonyms: Brown Saphire, Marron Zafiro, Saphir Brown, Saphire Brown, Sapphir Brown, Zaphir Brown, Zephyr Rot Cordieritefel: 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. Cordierite typically occurs in contact or regional metamorphism of argillaceous rocks. It is especially common in hornfels produced by contact metamorphism of pelitic rocks. Two common metamorphic mineral assemblages include sillimanite-cordierite-spinel and cordierite-spinel-plagioclase-orthopyroxene. Other associated minerals include garnet (cordierite-garnet-sillimanite gneisses) and anthophyllite. Cordierite also occurs in some granites, pegmatites, and norites in gabbroic magmas. Mineral Composition: Average by % Orthoclase: 62%, Quartz: 27%, Hornblende: 5%, Biotite: 3%, Plagioclase: 2%, Mafite: 1% Technical Specifications Compression Tensile Strength: 2364 kg/cm2 Tensile Strength After Freeze-Thaw Cycles: 2228 kg/cm2 Unitary Modulus Of Bending Tensile Strength: 312 kg/cm2 Heat Expansion Coefficient: mm/m°C Water Imbibition Coefficient: 0.001800 Impact Strength: cm Frictional Wear: mm Mass By Unit Of Volume: 2680 kg/m3 Hardness (Moh's Scale): Note: These figures and details are given for guidance purposes only, no reliance should be taken as to their accuracy. |
