Understanding Granite
Granite’s got a reputation for being tough, but what’s it really made of? Knowing its composition and properties gives you a better appreciation for this rock star of the design world.
Composition of Granite
Granite mainly consists of quartz, feldspar, and mica. Quartz takes the gold star here, making up around 20% to 60% of the composition, while feldspar usually counts for 30% to 50%. Mica adds the bling, contributing about 3% to 5% of the mix. This combo gives granite its signature speckled look, and also its legendary durability.
Properties of Granite
Granite isn’t just pretty—it’s tough as nails. It ranks a solid 6 to 7 on the Mohs hardness scale, which means it’s harder than steel (3) and glass (5). Plus, it’s resistant to scratching, chipping, and staining. Want some stats? It can withstand heat up to 1,200°F (648°C) without breaking a sweat. So, if you spill a hot pot of soup, your granite countertop won’t throw a tantrum.
The Hardness Scale
Granite’s toughness doesn’t just happen by chance. It’s all about how it scores on the hardness scale.
Mohs Hardness Scale
The Mohs hardness scale ranks minerals from 1 (talc, soft as a feather) to 10 (diamond, the hardest of them all). Granite sits comfortably between 6 and 7. That means it’s tougher than most kitchen disasters—like that time you tried to chop carrots with a butter knife. Its composition of quartz, feldspar, and mica makes it a rock star in resilience.
