If you are in the market for a new countertop, you may have heard of quartzite and granite. These natural stones are popular choices for kitchen and bathroom countertops because of their durability and beauty. But, which one is harder? In this article, we will explore the differences between quartzite and granite, and determine which one is harder.
Understanding Quartzite and Granite
Before we dive into the hardness of quartzite and granite, let’s first understand what these stones are and their characteristics.
Quartzite
Quartzite is a metamorphic rock that is formed from sandstone. It is composed mostly of quartz, which gives it a crystalline appearance. Quartzite is a very hard and dense stone, and it is resistant to scratches, heat, and stains. It comes in a variety of colors, including white, gray, pink, and green.
Granite
Granite is an igneous rock that is formed from cooled magma. It is composed mostly of quartz, feldspar, and mica. Granite is also a hard and dense stone, and it is resistant to scratches, heat, and stains. It comes in a wide range of colors, including white, black, gray, and red.
Similarities and Differences Between Quartzite and Granite
Quartzite and granite have many similarities, including their hardness and durability. They are both natural stones that are resistant to scratches, heat, and stains. However, there are some differences between the two stones. Quartzite is a denser and harder stone than granite, which can make it more durable and resistant to damage. Granite, on the other hand, is more porous than quartzite, which means it can be more susceptible to staining if not properly sealed.
Hardness of Quartzite and Granite
To determine which stone is harder, we need to look at their hardness on the Mohs scale of mineral hardness. The Mohs scale ranges from 1 to 10, with 1 being the softest and 10 being the hardest.
Mohs Scale of Mineral Hardness
- 1: Talc
- 2: Gypsum
- 3: Calcite
- 4: Fluorite
- 5: Apatite
- 6: Orthoclase
- 7: Quartz
- 8: Topaz
- 9: Corundum
- 10: Diamond
Comparison of Quartzite and Granite Hardness on Mohs Scale
Quartzite has a hardness of 7 on the Mohs scale, which means it is harder than granite. Granite has a hardness of 6-7 on the Mohs scale, which makes it slightly less hard than quartzite. This difference in hardness may seem insignificant, but it can make a difference in the durability and longevity of your countertop.
Factors That Affect Hardness of Quartzite and Granite
There are several factors that can affect the hardness of quartzite and granite. One of these factors is the mineral composition of the stone. The more quartz a stone contains, the harder it will be. Another factor is the density of the stone. The denser the stone, the harder it will be. Finally, the way the stone is formed can also affect its hardness. Stones that are formed under high pressure and temperature tend to be harder than stones that are formed under lower pressure and temperature.
Differences in Maintenance and Durability
While quartzite and granite are both hard and durable stones, there are some differences in their maintenance and durability.
Maintenance Requirements for Quartzite and Granite
Quartzite and granite both require some maintenance to keep them looking their best. Both stones should be sealed to prevent staining, and they should be cleaned regularly with a non-abrasive cleaner. However, because granite is more porous than quartzite, it may require more frequent sealing and cleaning to prevent staining.
Differences in Durability Between Quartzite and Granite
As mentioned earlier, quartzite is denser and harder than granite, which makes it more durable and resistant to damage. While granite is also a durable stone, it may be more susceptible to cracking or chipping if it is subjected to heavy impacts or extreme temperatures. Additionally, if granite is not properly sealed, it may be more prone to staining and etching.
Impact of Durability and Maintenance on Lifespan of Quartzite and Granite
The durability and maintenance requirements of quartzite and granite can have an impact on their lifespan. If properly cared for, both stones can last for decades. However, if not properly maintained, they may require repair or replacement sooner than expected. Choosing a stone that fits your lifestyle and maintenance preferences can help ensure that your countertop will last for many years.
Choosing Between Quartzite and Granite
When choosing between quartzite and granite, there are several factors to consider.
Factors to Consider When Choosing Between Quartzite and Granite
- Hardness: If you want the hardest stone possible, quartzite may be the best choice for you.
- Appearance: Both stones come in a wide range of colors and patterns, so choose the stone that best matches your design preferences.
- Maintenance: Consider the maintenance requirements of each stone, and choose the one that fits your lifestyle and maintenance preferences.
- Price: Quartzite is generally more expensive than granite, so consider your budget when making your decision.
Pros and Cons of Quartzite and Granite
Quartzite and granite both have their pros and cons.
Pros of Quartzite
- Harder and more durable than granite
- Resistant to scratches, heat, and stains
- Comes in a variety of colors and patterns
Cons of Quartzite
- More expensive than granite
- May require more frequent sealing and cleaning
Pros of Granite
- Less expensive than quartzite
- Comes in a wide range of colors and patterns
- Resistant to scratches, heat, and stains
Cons of Granite
- More porous than quartzite, which can make it more susceptible to staining
- Slightly less hard and durable than quartzite
Which Is Harder: Quartzite or Granite
Quartzite is harder than granite. While the difference in hardness may seem insignificant, it can make a difference in the durability and longevity of your countertop. However, both stones are hard and durable, and can last for decades if properly maintained. When choosing between quartzite and granite, consider your lifestyle, maintenance preferences, and budget to make the best decision for your needs.
Conclusion
We have explored the differences between quartzite and granite, and determined that quartzite is harder than granite. We have also discussed the maintenance and durability of both stones, and provided tips for choosing between them. By understanding the differences between quartzite and granite, you can make an informed decision when selecting a countertop for your home.
