Quartzite countertops are NOT quartz surfacing materials. Quartzite is an all natural stone product, mined from the earth. Offered in a wide variety of colors and patterns, every slab is unique. Most quartzite comes with a highly polished finish, although some stone comes with a honed surface.
Options - Choose from many options that make you counter truly custom:
Stain Resistance - Quartzite must be sealed with a quality natural stone sealer that is non-toxic for food service applications. If you re-seal you counter on a regular basis, the surface should stay relatively protected. The most important thing to know is that you can not use chemical cleaners to clean the stone. Chemical cleaners such as Windex, 409 and Simple Green will strip the sealer away, leaving your surface unprotected.
Heat Resistance - Quartzite is almost heat proof. The reason we say heat proof is that in some instances, extreme temperature change can cause a crack of fissure to split apart. Other than that, most cookware will not get hot enough to damage natural stone. Because of this, we always recommend a hot pad or trivet.
Cutting and Abrasion - Quartzite is the most scratch resistant surface you can put in your kitchen.Most daily use will not scratch the surface. Keep in mind, if using the surface as a cutting board it will dull your knives after the first use. For this reason we always suggest using a cutting board.
Impact - Although quartzite can withstand impact, if and when some a hard impact does occur, edges can chip.
Food Safe - If you properly seal your quartzite countertop and clean after each use, you should have a very clean and sanitary counter surface. Quartzite is not NSF approved for use in commercial food preparation areas.
Test your quartzite before you make your selection. Not all quartzite is the same. Use the test below to determine the suitability of your quartzite slab selection.
Quartzite Suitability Tests
Lemon Test - The lemon test is to determine the ability of your quartzite to resist etching. Follow the steps below:
- Place a wedge of lemon or lime, cut side down, on the sample overnight.
- Wipe the sample in the morning and hold it at an angle to the light.
- Check for a rough spot where the lemon was placed.
- Etching will appear dull and rough.
Etches normally occur where calcium or calcite is present in the make-up of the stone. If your sample reacts to the lemon wedge, we DO NOT recommend this for your kitchen.
Water Absorption Test - Test the suitability of your quartzite to resist water absorption.The tighter the grain the less absorption.;
Follow these steps:
- Place a few small drops of water on the sample
- Let stand for about 15 minutes.
- Wipe excess water.
If the quartzite sample absorbed the water as soon as you put it on, DO NOT use this quartzite . A quality sealer would help prevent some absorption, but would require constant maintenance.
If there is still a bit of water left on the surface, it will be suitable for your kitchen. We recommend a sealer for all quartzite .
