Formation of Granite

Formation of Granite

Knowing where and how granite forms can give you a deeper understanding of why it’s so hard. So, let’s dive into the geological process that births these unique slabs of rock.

Granite, widely known for its toughness and unique patterns, comes to existence deep beneath the Earth’s crust. This happens in the igneous process, where the molten magma solidifies under intense heat and pressure. Over millions of years, these once bubbling bodies of magma cool down, steadily solidifying into crystal-rich rock. Yes, the granite rock you use in your kitchen has been millions of years in the making!

The mixture of minerals present during this process gives granite its distinctive features. Commonly, this igneous rock comprises feldspar, quartz and mica. Feldspar lends a white or pink hue while quartz gives a murky translucent color. Mica, on the other hand, introduces the shiny flecks often seen in granite. All these minerals work together to create various unique colors and patterns. And, it’s due to this formation process that granite achieves a high score on the Mohs Hardness Scale, a scale used to rate the hardness of minerals.

In simpler terms, picture this scenario:

  • Molten rock (magma) under the Earth’s surface starts cooling down
  • As it cools, minerals like feldspar, quartz and mica start to form
  • This mixture of minerals solidifies over millions of years to become granite

This is granite rock formation in a nutshell!

Let’s proceed to understand how this toughness can benefit kitchen countertops.

Properties of Granite

Now that you’ve learned about the formation of granite and what gives it its distinct colors and patterns, let’s delveinto its remarkable properties. These properties not only define its aesthetic charm but also its durability and resiliency, making it a popular choice for various applications, especially for kitchen countertops.

One of the key properties of granite is its astounding hardness. It holds a significant rank of 6 to 7 on the Mohs Hardness Scale, which measures the ability of a specific mineral to withstand scratching. It’s the presence of hefty minerals like quartz and feldspar that attribute to such robustness. It’s not surprising then that your granite countertop can take a beating and still maintain its pristine condition.

Here are the hardness values according to the Mohs scale:
