Quartzites
Ava Blue
The origin of Ava Blue dates back billions of years ago, when quartz grains were deposited over huge cracks in the earth’s crust in Bahia, accumulating sediments for millions of years. Over time, deserts, rivers and seas that were formed rose as metamorphic mountain ranges, after huge phenomena such as the ancient continental collision. Full of mineralization, this quartzite displays traces of hematite crystalline fractions that give it a bluish tone, revealing a vibrant geological past.

![Petrographic Analysis](http://decolores.dev.duoapp.com.br/media/853/1-analise-petrografica.png)
Petrographic Analysis
It consists of classifying the rock through the macroscopic and microscopic description of its characteristics, such as minerological composition, alteration, deformation and microcracking pattern.
![Apparently density](http://decolores.dev.duoapp.com.br/media/857/1-densidade-aparente.png)
Apparently density
Relationship between the mass and apparent volume of the rock. It provides the weight of the rock, being an important parameter for calculating loads in buildings.
![Apparent porosity](http://decolores.dev.duoapp.com.br/media/858/1-porosidade-aparente.png)
Apparent porosity
It is the relationship between the volume of voids and the total volume of the rock expressed as a percentage.
![Water absorption](http://decolores.dev.duoapp.com.br/media/859/1-absorcao-dagua.png)
Water absorption
It is the ability to assimilate or incorporate water into the rock, expressed as a percentage.
![Abrasion resistance](http://decolores.dev.duoapp.com.br/media/860/1-resistencia-a-abrasao.png)
Abrasion resistance
Determines the wear rate due to friction of particles with the surface of a rock plate.
![Bending resistance](http://decolores.dev.duoapp.com.br/media/861/1-resistencia-a-flexao.png)
Bending resistance
Simulates flexural efforts in rock pacas, with predetermined thickness, in this case simulating the effect of wind on plates fixed to facades with metal anchors.

![Stain resistance](http://decolores.dev.duoapp.com.br/media/863/1-resistencia-ao-manchamento.png)
Stain resistance
Stress that causes rock to rupture when subjected to compressive stress.
