Quartzite is easily one of nature’s most versatile stones, and has become increasingly popular due to its durability, unique patterns, and vibrant colors. The Aria team is here to answer any questions about this incredibly sought after stone.

Will it Scratch?

The long and tedious process of sand compression and heating makes this natural stone incredibly dense and durable. According to the Mohs Hardness Scale, it is more durable than granite or steel. Meaning, if you were to use a steel kitchen knife without a cutting board on your quartzite countertops, it is more likely that you will damage your steel blade than the countertop! So needless to say, scratches should not be an issue with this natural stone in your home, even in high traffic areas and highly used spaces, such as the kitchen.

Will it Etch?

If you cook frequently and want to make sure that your countertops are safe from etching then you might want to consider quartzite. It will not etch from acids found in household items such as vinegar and lemon juice. However, both quartzite and granite react to hydrofluoric acid, which is found in some heavy-duty rust removers. Thankfully, hydrofluoric acid is not a common ingredient in household (or kitchen) products.

Will it Stain?

All quartzites are different in terms of porosity and stain resistance, and some are more stain-resistant than others. They are not stain proof, but most are incredibly stain resistant.

To help explain, let’s take a trip back to your early Earth Science class. You may remember that stone, such as quartzite, is formed over the course of many thousands of years. During this time, minerals undergo the “mineral metamorphic process” where the minerals bond and compress tightly together to create the stone. The tighter the minerals bond, the more stain-resistant the stone.

That being said. Nothing is stain proof. Use a sealer to avoid stains from common household items. Seal your natural stone about once a year with a home application sealer to maintain this coverage.

Debunking The Terms of Different Quartzites

According to the Marble Institute of America, there are many products on the market that are labeled as “soft quartzite,” “calcitic quartzite,” and “dolomitic quartzite.” Note that these products share only some of the same properties as quartzite. With marble, calcite, and dolomite all rated around a 3 on the Moh’s Hardness Scale and quartzite rated at 7, these varying labels are typically trying to convey that they fall somewhere between a 3 and a 7 on the Moh’s Hardness Scale. Meaning, they are harder than marble, calcite, or dolomite, but softer than a quartzite.

It is important to be aware of the difference, as marble, calcite, and dolomite are soft and therefore more susceptible to scratching, etching, and staining than a true quartzite. Of course, these effects can be lessened by using a sealer, but it is helpful to know beforehand to avoid any misconception of your stone.

How Do I Test To See If I Have a True Quartzite?

Easy! Household kitchen acids, such as lemon juice and vinegar, will not etch a true quartzite. One way to test is to simply pour some lemon juice or vinegar on your stone and let it sit. Wait for 15 minutes and then wipe up your test area and look for an etch. Depending on the coloring of the stone, etching may look more dark, light, or dull than before. If any etching occurs, then it is not true quartzite. For this test, sometimes it helps to take before and after pictures to best compare the results!
