Granite or Quartzite Counter"Super White" is actually a Dolomite?

10 years ago

I went to the yard Super White is actually a Dolomite neither a Quartzite, marble or granite - its sort of in between a granite and marble in strength they said.

What do you think of the look of this Super white with my Espresso cabinets?

Any suggestions for backsplash or other color of counter? Thanks so much

Anyone have recommendations on Dolomite or have they ever tested the actual durability of Dolomite like Super White vs a pure granite or real Quartzite?

We have honed Super White and it has NEVER stained. We are red wine drinkers and entertain a lot and even with wine left on all night - it just wipes clean in the morning. BUT we have had it etch with lime juice from "beergaritas" at our July 4th party. But because my stone is honed no one can see the etching but me. Not even my husband notices it. Our installer said he went through several blades with the stone because it was so strong. I would do Super White again for sure. We've had it for almost 3 years now. We sealed it with whatever the one was at Home Depot. Can't remember the name though. I never was able to get professional pics taken for a "reveal" post but here it is. You can see we used it on our black/brown island too.

Heres a pic of the "Super white" Dolomite

Often it's called a quartzite but the rep at the yard said its "slightly weaker than a quartzite but stronger durability than a marble"

I was considering super white (it was sold out otherwise i would get it) and i got a piece that i brought home. Everything stained it, lemon etched it and i could easily scratch it. it looked exactly like yours. I still love it, i think it is like looking at Antarctica from the helicopter (never actually seen it, just my imagination:) )

Super White (not granite, not quartzite, marble-ish dolomite)

Mamabear, I'll gladly be your enabler. I fell in love with Super White here on GW. When we went to look at slabs at the fabricator our builder used, I didn't hold out much hope that I would find any slabs so never mentioned Super White to DH. As we were walking through the yard, DH was ahead of me. I found him stopped in front of a lot of SW. I couldn't have asked for a better reaction from him. We tagged 3 slabs and took loads of pictures. I committed the GW sin of not obtaining a sample so no testing was done. I was just excited to have found this amazing stone and that DH was totally on board with it. Much drama occured after templating that I won't go into, but ultimately, we ended up with gorgeous countertops in our kitchen, master bath and half bath. We had the fabricator apply a sealer that supposedly would protect it for 10 years. One year after moving into our new home, I have experienced no staining or etching. I'm not an obsessive housekeeper, nor is DH who is home during the day while I work. I do have some small pieces now that I could test, but I've chosen not to. Don't want to jinx my good fortune. Good luck with your decision. I'm certainly happy with mine.

Super white / calacatta quartzite countertop - cleaning? Staining?
Q
Comments (22)
Hi Lisa. Happy fourth. We just had calacatta lux installed five days ago. Love the look. The horror stories on Houzz however are frightening. Water beads as was promised on counter when they sealed but edge near sink discolored from droplets. It did fade away in about an hour. Have you had any problems or did you have any staining? How was it processed? Ours came the day after it was cut and hoping down the road I don’t experience the edge stains. Anything you can add is very helpful. Thank you again. Your kitchen looks fantastic! After reading all this I’d be grateful to hear your experience. Tks!

How to maintain Super White Dolomite While Dolomite is a super tough natural stone, it does require a little bit of maintenance to ensure it not only lasts a lifetime, but does so looking as sparkling and cleanly as you’d like. Luckily, it’s easy to maintain with just a little bit of proactive care. Clean up spills as soon as they occur. Avoid using knives or other cutting instruments directly on the stone. Seal your Super White Dolomite. Clean using warm water and a soft sponge. Avoid using abrasive cleaners or harsh chemical Ceciliano Marble & Granite Inc 142 Fisher St, Westborough, MA 01581

Super White kitchen countertops?
Q

Super-white quartzite is supposed to be a quartzite not a marble. The high quartz content is what makes it a quartzite and thus gives it the unique properties of a quartz countertop. Durability, stain resistance etc.. For example, manufactured quartz countertops use quartz within them to emulate the desirable properties of quartzite. From experience you want to look for a slab that has less fissures throughout the slab. These fissures are noticeably yellowish tinted quartz between the "whiter" parts of the slab. These are the areas that are more susceptible to staining particularly. However, always keep in mind with natural stones there is always the potential for inconsistencies and irregularities. In terms of products for sealing, I have used many brands with positive results. I believe application to be more of the concern then the product in a sense. Sealers must be applied in multiple coatings until the slab can no longer absorb the newest coating applied and thus leaves a wet-ish residue on the surface which then gets removed with a cloth. I recently had a conversation with a client of mine who I installed a super-white counter for back in 2016. I was informed that the slab has never stained and has remained very easy to clean and has not been damaged.

Holy cow, a stone dealer actually got the rock type correct with Super White! That's the first time I've heard about anyone getting it right.

Yes, it's dolomitic marble (dolomite that has become a metamorphic rock). It's minimally more acid resistant than marble or limestone. Durability-wise it's the same. Lots more info is in the thread below.

Thanks karin for posting truthful info.

Yeah this dealer seemed to know more than other yards. I went to a couple others and saw Super White or similar ones labled as "quartzite" and was told by them that Super White was very strong etc.

From the stone yard I got a Dolamite, Quartzite and Granite sample here are results of a glass/ scratch test:

I tried a scratch test and the "Super white" Dolamite did not pass the Glass test where you try to scratch a glass bottle. The White Macauba Quartzite easily scratched the glass. A third Granite sample also scratched the glass

I then did a scratch test first with a spoon and the Dolamite, Quartzite, granite all passed without getting scratched when I pushed hard on them

The final test I did was with a sharp serrated plier. This could not scratch the quartzite, barely scratched the granite and easily scratched the "super white" Dolomite

I guess the super white is no good

I'll do an acid test later with lemon/ vinegar and stain test with wine.

One other question:

Does Quartzite seal the same way granite does? Would you use the same product to seal it?

Nice work on the scratch tests! Your results make sense.

Yes, the same sealer can be used for quartzite and granite. Some quartzites are fairly porous so they'd need more sealing.

That Super White Slab is gorgeous! I wish I could help but I have not revisited my search for counter tops yet and I am still learning.

When we picked our Super White slabs the other day the stone company also called it a Dolomite. Maybe they are catching on :)

Love the look, but I have to prioritize durability in my kitchen. I'm going with the one shown in the thread below.
