It will be good to see a photo of the tile. Just some thoughts right now though. There are few GW's who have installed complete glass backsplashes. These look like a solid sheet of glass, because they are. Your tiles will not look solid because you will have the the shape of the tiles and the grout. But, visually, it will be a wall of one color.
The majority of backsplashes here are one color. What is your floor?

I can't tell you exactly about the bs without seeing the tiles pictured, but I can say that any samples you have that you don't need will be greatly appreciated by the local school's art teacher. I think that our son's teacher is probably disappointed we have finished our reno (at least the ordering/purchasing part). They can use them in their arts and crafts projects ;)
We sent in samples of flooring, tile, siding, etc.... all were welcomed with open arms.

I like idea of glass subway tiles. Glass subway tiles can look nice but they can look one note. If you really like this idea I would use a darker grout to distinguish the tiles from one another and give the BS some more dimension. For size 3 x 6s are more classic where the 4 x8s might look more modern, but IMO I think using the 3 x 6 in glass is a nice mix of modern and traditional. It might look better in your more traditional kitchen as well.

I forgot to mention to check out modwalls.com. They have all different types of glass tile, subway sized and mosaics as well. Not that you want to add anything else to your drawer but they are worth a look. I purchased the mosaic over my range from them and they were great to work with.

I have Daltile Cream Soda backsplash. My cabinets are white and my counters are honed absolute black granite. The tile looks great on the backsplash. It has more color when installed. Mine has a gold-olivey look to it. My husband wanted color. I wanted a neutral. It was the perfect compromise.

Thank you for the responses thus far. I gained something from each. Keep them going and I will try and photograph the tile.

Dawnpfister....great news..can you post a picture of your kitchen. I assume it is glass but maybe not. What size tiles are they. Would love to see it. Thanks!

I will throw some ideas at you. This one, I just came across yesterday, would give you the variation with the reflectivity. Some of them have closeout prices.

Here is another that is very specific to taste. You may hate it. I love it and think it would look great with ubatuba.

My cabinetry and countertops are similar to yours. We had a darker backsplash originally, but it made the kitchen look drab. We replaced the back splash with a light color tumbled marble. Perhaps a photo might be of value. Scroll to the bottom of the page to see our kitchen.

With this tile, your kitchen would look (sort of) like this:

Don't know how you did that Suzannes1 but it gives me a pretty good idea what the daltile would look like. It doesn't wow me but it is nice.

Does anyone have any suggestions of a subway tile that might have more shading in it? Of course not in glass but I am open to other materials..just not stone or anything of a rough texture..still in the pale gold coloration? Many thanks.

Essie4, what did you end up going with?
