Granite has been used in the design of many sculptural and architectural projects, from tiles and countertops to the faces of Mount Rushmore. This rock, however, is more than just an interior design option. Research by geologists has found that granite and granite countertops have a far more fascinating background than most people would guess.

If granite countertops intrigue you, Motor City Granite & Cabinets provides a wealth of information about these stylish stones. Take a break from researching your interior design options to explore four interesting facts about granite countertops.

A Slice of Geological History

While granite is not the oldest rock on Earth, it is the oldest igneous rock in the world. As a type of plutonic rock, granite forms when magma underneath the Earth’s surface cools and crystallizes. Records from geologists suggest that granite began forming as long as 300 million years ago.

In addition to its geological history, some forms of granite have developed historical or cultural significance over time. For example, blue hone granite is a form of granite unique to the Scottish Islands, with an unusually smooth surface owing to the crystallization process.

Although the rarity of the stone makes it unsuitable for countertops, blue hone granite is considered the ideal stone in the sport of curling.

Different Hardness Ratings

Granite cannot be assigned a true rating on the Mohs scale of rock and mineral hardness. The rock usually consists of quartz, feldspar, and mica, all of which have different Mohs ratings: quartz and feldspar have a hardness of 7 and 6, respectively, while mica can range from 2.5 to 4.

Granite countertops are usually estimated at between 6 and 8 on the Mohs scale, but the countertop’s true rating depends on the composition of the granite. Despite this, granite is a durable material that, with proper care, will last for many years.

Slightly Radioactive

Granite countertops contain very low levels of radiation, though not enough to be dangerous. This stone can contain trace amounts of uranium, thorium, or radium, which naturally exude low levels of radon.

However, you do not need to worry about your countertops causing radiation-related illnesses. The Environmental Protection Agency reports that radiation levels from granite are already extremely low.

In addition, granite is not a porous rock from which radiation could easily escape, and external sealants on your countertops provide an additional barrier.

The Right Granite Can Add Value to Your Home

Since granite’s structure closely resembles coarse grains, every countertop will have its own unique colors, patterns, and shapes. When searching for new countertops for your kitchen or bathroom, you can browse a variety of countertops until you find the perfect match for the room.

Taking the time to find the best-looking natural stone can add value to your home, should you eventually decide to sell.
