Granite is the most durable and impact-resistant type of stone. Always present in Portuguese kitchens, mainly in countertops and wall cladding, and now adapted to several countries around the world, granite stands out from other types of stone by presenting a massive structure of low absorption and porosity. In the case of the Portuguese silver grey granite, it integrates a dispersed grain with a dark grey pigmentation with black details, and may integrate some dispersed white/grey touches. Depending on the extraction area, the colour and density of the pigment may vary.
Suitable for any kind of surface as well as decorative elements, granite is one of the most coveted types of stone in terms of durability.
Granite is an igneous plutonic rock that forms when magma (molten aluminium) slowly cools to great depths in the earth’s crust, making it very hard. This then causes granite to have a high breaking strength.
Brushing the slab with a range of brushes and the result is a slightly undulating surface, very soft, warm and smooth to the touch.
Blasting silica sand against the material through an air gun and generates very small craters.
Rough and irregular surface with small furrows and undulations in a mate tone.
Hitting the material, with a masonry tool called a bush hammer, that generates uniformly distributed craters of different sizes over the surface of natural stone.
Exposing the surface of the stone directly to a high-temperature flame that generates a thin roughness.
Abrasive brushes under high pressure generate a touch-sensitive and smooth surface of natural stone.
A honed finish is identical to the polished finish, the surface is smooth but without glare or light reflections.
Abrasive treatments with repeated applications result in a shiny surface, highlights the colour and properties of the natural stone.
Splitting stone either by hand or by machine so that the surface exhibits a natural quarry texture.
