EGYPTIAN GRANITE

Granite is a rock of volcanic (igneous) origin that has cooled slowly within the earth's crust.

Think of the liquid lava which, unable to escape from the depths of the earth, moves slowly inside, cooling down and undergoing all

a series of chemical and physical transformations.

In the very long process (called metamorphic) of solidification and transformation, the mineral impurities - present in granules or layers

sedimentary within the lava flows - they have moved and recrystallized as a result of pressure and heat. These processes have created a

hard, compact and resistant material, but with very beautiful grains capable of satisfying the most refined aesthetic tastes. Impurities such as clay, silt,

sand, iron oxides and flint nodules have given rise to the different colors of the granite (red granite, black granite, blue granite, etc.)

What are the characteristics of granite?

Granite is resistant to water, heat and grease, but remember to never use abrasive or acidic products to clean it, as this could cause irreversible damage to the surface. Also, avoid using vinegar or lemon juice.
