Sorry about your quartzite. Unfortunately there seem to be many issues with quartzite in Houzz discussions. Also see this: https://www.stoneworld.com/articles/91843-stone-summit-theres-something-about-quartzite I hope your fabricator will be able to help.

thank you , but the article really didnt answer my concern. couldnt even read ir, as I have to subscribe to it . I have fantasy brown quartzite in a summer kitchen for over 8 years. not a single issue.

if nahone has an answer or experience with this, please do post.. im very upset and nervous about what i see

Im not certain the pics posted . here they are again. I have read posts of people having issues with water seeping theough, as well as the usual culprits of oil, acidics etc. however what is odd is that there is no water even hooked up in my kitchen, and the island isnt anywhere near water! which leads me to believe what the fabricator said about it getting wet during cutting. however, im concerned maybe its defecrive or somehow got saturated with somehting and is permannelty stained (?) bizarre its just those two areas . wouldnt all the stone be saturated if it was due to being wet cut and polished? i mean they have to cut the entire thing, not just those two areas . doesnt make sense to me.

Hopefully Joseph will comment but I have quartzite in my kitchen and never had an issue with it in the 4 years it's been installed.

Thank yoy cpartist

i also have quartzite ( fantasy brown) ) in our summer kitchen for 9 hears no issue at all as well same fabricator . have been using them for years.

i believe joseph is well versed in quarttz; which is man made.. this is quartzite; a natural stone. but, perhaps im wrong on that and he has experience with natural stone and has seen this before .

thank you very much!!

Based in numerous discussion threads on the subject, it seems quartzite discoloration isn’t unusual (search for ”quartzite discoloration.”)

Give it a week or two please.

Don't pay the balance please until it's gone.

Thanks spammie, however most staiming seems to be with use. these were brought in and installed like this!!

i dont know what the heck it is or how it for there. Doesnt make sense

Thanks for responding joseph .

can you summize what it may be?? it was brought in and installed like that. i thought maybe it was rainig out and got wet..

installer said confdently ” that will go away in about 2 hours.”

6 hours later when srill there , i called the fabrkcator. he said give it a day or 2. the stone gets wet during cutring/ fabricarion. if it doesnt go away , then the boss will come take a look at it.

im not sure what to think .

You can put a heat gun on it which may speed it up. It is probably from cutting.

I speak with stone fabricators online occasionally and many are no longer working with certaiin quartzites due the water/stain absorbtion issues. It's just not worth the risk.

This is a stone with some issues for sure . I agree with Joseph wait and see what happens in the next few days and do not pay until you are happy. BTW are these the actual slabs you chose in the stone yard? The fact that this fabricator is known to you should be agood thing . I love quartzite but many fabricators hate working with it for many reasons .My stone yard tells me Fantasy Brown is actually a very hard marble not a true quartzite.

Other slab . the left corner one is where marking are now

Joseph, im afaid oauing the bakance is too late

when the installer said dont worrt the marks will dry hp in about 2 hours., , i signed the wokr order receopt. my credit card is on file to process the payment. ,

worst case scenario- god forbid they do not make good on this - which woud be horrific seeing i am a customer for 10 years, i could dispute the charge with my Credit card company. i sadly have had tonthat before with a few cases and have been successful

Other pic of tape marking of slab no staining anywhere like what is on it now

the piece in question is left corner along the edge.

intersringly the island piece is also entire left side edge.

nothing on the other two pieces or on right sdie of island piece.

Fabricator said he is going to send someone to aoply another cost of sealer and use a torch to try and dry the stone. .

anyone ever heard of this? , had it done? been successful? ive never heard of this before

If it's been sealed, that might be why it's taking so long to dry. I don't think you want MORE sealer until it is dry.

The extra sealer might be a sneaky way to make it all look wet so you don't notice the wet bits.

Thank tou fori

oh trist me… ill see if its all now looking a wet color. and i will make an issue of it, as thst would mean the entire stone , all ober the olace would be sognificantly darker than what it was in its original state. im not accepting that. A bjg part of the reason i chose the stone was for the color- a lkght grey/ blue. the wet spots do not look like a light grey blue.

i have pics of the slabs when we chose them, pics if the slabs with taping showing where to cut and pics immediately after install with the dark spots.

Ive been reading some and have learned that there are different types of sealers. some being enhancer sealers, which apparenrltly darken narural stone .

i am going to specify and check that they do not iuse an enhancing sealer as a way to just blend it all and make it darker overall. as stared , i chose it for its light color, i in no way want it dark like what the discolored spots look like now.

"anyone ever heard of this? , had it done? been successful?"

Yes. I've done it successfully. Set the sink on fire for a few seconds from the acetone, but it went out before it caught the curtains.

Joseph… im sorry but what the heck are you talking about? i dont need a damn sink fire.

He is talking about the torch being used to dry the stone .

Fabricator coming on tuesday to inspect the counter . he said thet have nit seen anynring like this . he said he origianlly thoight it may have been water from being fabricsted , but it should have improced in a day or 2. he said to rest easy, as fhey will try to figure out and address the problem, but if nothing works, they will remake and replace the countertops if need be . i feel better knowing they will stand by is and do the right thing, but upset, as it really is beautiful quartzite and having to possibly redo it all stinks . uuuugghh!!!
