Juparana Bahia Champagne Granite Image

Description: Juparana Bahia Champagne granite is a fine-grained, brown-pink gneiss or migmatite of the Precambrian period with black biotite-streaks. This stone internationally may be nominated as a granite but in the area of application of the European Standard we are awaiting clarification however this stone will be nominated as either a gneiss or a migmatite. The veining and colour varies considerably and a small sample of Juparana Bahia Champagne 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. Juparana Bahia Champagne 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: Juparana Bahia Champagne 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 Juparana Bahia Champagne 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: Juparana Bahia Champagne granite is quarried in Brazil.

Synonyms: Japarana Champane, Juparane Champagne, Juparna Champagne

Gneiss: A high grade metamorphic rock. Gneiss is medium to coarse-grained and may contain abundant quartz and feldspar, which some petrographers regard as essential components. The banding is usually due to the presence of differing proportions of minerals in the various bands; dark and light bands may alternate because of the separation of mafic (dark) and felsic (light) minerals. Banding can also be caused by differing grain sizes of the same minerals. The mineralogy of a particular gneiss is a result of the complex interaction of original rock composition, pressure and temperature of metamorphism, and the addition or loss of components.

Migmatite: A rock at the frontier between igneous and metamorphic rocks. They can also be known as diatexite. In many cases the darker part of the rock, consisting of biotite mica and hornblende, has been intruded by veins of lighter rock consisting of quartz and feldspar. A rock composed of a metamorphic (altered) host material that is streaked or veined with granite rock; the name means "mixed rock". Such rocks are usually gneissic (banded) and felsic rather than mafic in composition.
