Crema Bordeaux Granite Image

Description: Crema Bordeaux granite is a highly patterned, cream-grey-pink-red gneiss. 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 gneiss. 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. Crema Bordeaux granite is suitable for both interior and exterior use futhermore is frost resistant and with a constant polish.

It is very common to have Crema Bordeaux slabs strengthened with fibreglass netting. Colour variation and texture of Crema Bordeaux granite is very wide, a small sample is not usually representative therefore for large projects swatch samples must be approved.

Products: Suitable for construction projects both commercial and domestic, prefabricated countertops/worktops, vanities, tiles, backsplashes, paving, fireplaces and memorials.

Surface Finish: Crema Bordeaux 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 Crema Bordeaux 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: Crema Bordeaux granite is quarried in Brazil.

Synonyms:

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.

Metatexite: Migmatites are sometimes sub-divided into metatexites, that have experienced low degrees of partial melting, or diatexites, that have experienced high degrees. Metatexites can also often be termed hornfels or gniess and are prefixed with "migmatised".

Petrographic Composition: Average Microperthitic Microcline: 40%, Quartz: 25%, Oligoclase: 25%, Biotite+Chlorite+Clay Minerals: 10%.
