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 syenite.

A small sample of Cafe Bahia granite is usually representative not having a wide variation in colour and veining however swatch samples must be approved for large projects to ensure that the blocks are all extracted from the same quarry face for matching purposes. Ideal for both interior and exterior use, Cafe Bahia granite is frost free and polish constant.

Mineral Composition: Orthoclase: 65%, Aegirinaugite: 12%, Quartz: 10%, Plagioclase: 5%, Biotite: 5%, Hornblende: 3%.

Physical Characteristics:
Tensile strength after freeze-thaw cycles: 1599 kg/cm2
Unitary modulus of bending tensile strength: 104 kg/cm2
Heat expansion coefficient: 0.0013 mm/mC
Water imbibition coefficient: 0.003800
Impact strength: 41.50 cm
Mass by unit of volume: 2682 kg/m3

Syenite: A coarse-grained intrusive igneous rock of the same general composition as granite but with the quartz either absent or present in relatively small amounts (<5%). The feldspar component of syenite is predominantly alkaline in character (usually orthoclase). Plagioclase feldspars may be present in small quantities, less than 10%.
