I think your personal experience with the bathroom window is instructive.

Put some film over the skylight.

Okay, there must be a UV film available. I didn't think of that. Thanks!

IMO real stone has been exposed to all kinds of things and I have never seen one yellow after install I have had a huge chunk of amthyst sitting on a dresser in a window for 18 yrs still looks exavcly the same and exposed to s. window light all the time . Might have faded a touch but not enough to notice . Slabs of stone sit outside in both the places where they come out of the mountain and in stone yards sometimes for years .

"Maybe stop using fake stone and get real , plastic discolors real stone not."

Many "natural stones" are resinated (plastic) at the slab processing plant. That resin is just as susceptible to UV degredation as many other materials. Don't even think about using a resinated stone outdoors unprotected.

I am looking at a Pitaya white granite as well. I would not want that to yellow due to being "resinated." I guess there is no way to know if your piece of granite has resin in it or not, and I guess some slabs require that process for structural reasons. But, Joseph does make a point that even buying natural stone does not mean you fully avoided synthetics.

Patricia, I would rather have natural stone any day. But, I am unsure about the sealers and potential forever chemicals. The slab of granite I am looking at is Sensa, and that has its own sealer. I have someone in the household with chemical sensitivities. I figure the resins in the quartz may have outgassing issues. I am considering soapstone, but like a lighter look.

Lantern Visual, thank you very much! I appreciate your comprehensive analysis of my situation. The takeaway is for me to consider high quality quartz if I use it and to have an understanding (with myself!) that there is risk for some degree of UV discoloration over the long run. I think it is an intelligent guess that the light in the kitchen with the (realtively small) skylight would not have the same impact as the window light in the So. BA...which is not the same as no impact.

Just to add an interesting note. I am not so dissapointed that the quartz in the So. bathroom yellowed. It is more like a honeyed white, a light bisque. It is evenly discolored and it goes fine with the maple cabinets and the aqua glass tiles. However, lesson learned. I should definitely have put a shade or curtain over that window. The UV window performed less than expected. It is the only cheaper window in the house, due to that remodel occuring before adding all Milguard Sun Coat dual pane, quiet line windows for the rest of the house. I should have replaced that window as well, even though it was relatively new. Cheap now, pay later!

I am grateful for people's generosity using their brain power and experience to weigh in. Thank you!

Pattaya?

What do you mean ”resinated”?

The kind of granite I am looking at for my kitchen is called Pitaya white.

Resinated means resin is sometimes injected into the pores of the granite to give it integrity. Joseph mentioned this in a post above. I really did not know about it. I just did a little reading on it after I read his post.

Dupont Corian , is non photo sensitive. It will never yellow.

"Constant exposure to harsh UV rays won't damage your Corian® surfaces. Rest assured that the beautiful countertops in your outdoor kitchen will stay in perfect shape".

There are a host of whites from which to choose. It is STILL a fantastic surface.: ) and is no more "fake" than quartz.Which will be much more limited in "whites" available.

It is the original solid surface. I am not talking about dated colors or speckles....It is carefree, it will stain from NOTHING....it seams beautifully.

I've had Cameo White in a kitchen and a bath for twenty years......simple, lovely.

That this oh so versatile surface took a back seat? Is just crazy. Don't believe me? Ask @ Joe Corlett up there above.

All said? A kitchen update is first layout: ) and what is that by the way? Show it all angles.

In any case, a different discussion if you want this:

Is there a why with that? Looks a bit 2000 year to me.

2000, yep. Jan, thank you! Love your posts, you are always straight to the point with an opinion. And that's what I want, strong ideas and info. Also, in your posted photo, I'm seeing how gray-ish the PW can read. I have a sample and don't love what I see as green/gold undertones next to the gray ones.

Main message in response to Corian:

I like the idea of Corian. I love forever white, and something plain for my mid-century ranch house (but not built with MCM sophistication). Granite seems out of place. I will take a look at Corian, which I've ignored as an option.

So, my husband really likes the Pitaya white granite. He is the cook in the house. He would like the surface to withstand a hot pot, "just in case" he ever mistakenly puts it there. He is used to sloppy cooking because we have an old tiled counter that withstands anything. Husband's kitchen practices may exclude Corian, but worth a discussion.

EXTRA info, if anyone is curious...

These are our combined requirements:

Husband (sloppy, ardent cook)

Heat resistant

White or light color

Non staining

No quartz due to Silicosis of workers

Me

Away from plastic (Eco reasons)

I don't generally like patterns

I've been considering Soapstone, White Quartz and Taj Mahal Quartzite

Since Corian LOOKS LIKE what I want to look at every day, I will look into it. I also sense that my Eco bent away from plastics won't necessarily be solved by granite or quartzite (e.g. sealers, epoxy, resin). It is realtively LESS plastic though.

I showed my layout in previous post, but will post it here or another post with inspiration photos, and my floor, & counter samples. My requirements have become so narrow, I'm def. a "difficult case."
