Granite Producst

Granite is an igneous rock that was created directly from the cooling and crystallization of molten material. Molten materials, which are formed from the melting of rocks of the earth's crust, have a silicate composition, and magma may freeze gradually in the depths of the earth or in fractures. In this case, an internal igneous rock is formed, which has medium to coarse grain crystals. The magma that reaches the earth's surface is called extrinsic igneous, which has a glassy texture. Gabbro, diorite, granodiorite, and granite are examples of internal igneous rocks and basalt, andesite and rhyolite are examples of external igneous rocks.
