When talking backsplash concepts, no one asked you what decorative items will you display in your beautiful kitchen. Do you collect china, baskets, pottery, or change decor themes seasonally? Will you ever change your backsplash again, or will it be the same one as long as you own this home? What is your design inspiration for this room? (Artwork, soft furnishing fabrics, or collected items like :Portmerion China with green, blue splatterware, gorgeous pottery with colorful glazes, Fiesta Ware?) The design world is offering new choices at the fastest pace ever. (Thanks to being able to share new designs immediately via the internet.) Will you regret installing something that is the "latest flash in the pan"? Mosaics in general fall into this category. The 60's one inch mosaic tiles, the 70's use of orange, gold and avocado, the 80's and 90's embossed tiles, then the introduction of the first water jet cut tiles that have led to the high end stone mosaics. Tile shape-square, diamond, subway running bond, pencil strips, each speak to an era. But the important thing to remember: this is your kitchen. Unless you built to flip it, you are the only one who has to love it. Keep in mind what really tickles you. What really excites you in the way of style? Stay on that path. Your kitchen has a very traditional feel to it. Will the use of any glass tiles date it too quickly? Some current trends disappear sooner than others. It takes a good tilesetter to install certain mosaics. Some of the glass tiles on the market have a color layer behind the glass, rather that being "true color glass". It you are very picky these may not please you once installed. (The color layer shreds when cut on some I've installed for a friend). I like the mosaic on the right, too. It seems rich, yet neutral. I've had my soapstone counters for about 12 years. I didn't want the "shiny granite" look in my kitchen, The splotchy look will come and go, depending on how much oil or wax has washed off. It will take semi regular sealing or oiling to keep the consistent dark color. (Which I prefer, but not all do.) The counters are "very soft", and will get dinged up pretty good. I wanted an "old farm house" feel, and I got it. When the chips on the counter bother you, sand them a bit. I have used a nail file on the chips on the edges, which then make it easier for the oil to be absorbed there. (Continue sanding with finer grits to smooth as desired.) I don't mind the dings, I just don't want them to stand out as white against a predominantly black countertop. Have fun as you continue. Remember, the only "right answer" is what pleases you for your lovely workspace.

Here is a link to google, how that backsplash should have been installed. There are some u tube videos too. I watched one video, where they used grout, between the countertop and the backsplash, and grout should not be used there. Caulking shud be done between backsplash and countertop. My backsplash is also caulked in all the corners, rather than grouted. Once you watch these videos and read these articles, you will see that your thinset was put on improperly, and thats why your tiles are falling off. Please read carefully. https://www.google.com/search?source=hp&ei=uI4VW7HdLszKjwTtrqSoAw&q=how+to+install+glass+subway+tile+backsplash&oq=How+to+install+glass+subway+tile+&gs_l=psy-ab.1.0.0l3j0i22i30k1l3.3755.12143.0.14244.41.29.3.9.9.0.173.3348.9j20.29.0....0...1c.1.64.psy-ab..0.41.3556...0i131k1j33i22i29i30k1.0.70wb9L5GlO8

I don't know what your client has in mind completely. It might be worth asking the client for some inspiration pictures for what she has in mind. I think some glass mosaics might be overpowering for that granite. But there are some glass mosaics that might work as long as they are very plain. Super white glass tile Maybe something like this with a tiny bit of pattern: Silver planks glass tile Or maybe this one which might work with the colour in the counter: glass mosaic - raw silk

Did you go with a white? Would you mind posting the color you went with and a picture? I actually have the same question and have the samequartz counter top It appears and white cabinets and glass tile! :) Love the white on white look but am a little concerned as my tiler advised against due to cleaning issues with white. What do you think or any on this post think? thank you!
