Glass Mosaic Tiles for kictchen backsplash
From what I understand, some glass tile is "colored" all the way through the tile and the back (that goes against the wall) is the same as the front. So, if you had blue glass tile, the color is throughout the tile. With the tile I bought tile, if you held it "sideways (cross section), it would look clear - the light green color comes from the color on the back side (that goes against the wall) of the tile that is light green. So, you can't see through the tile (appears opague from the back side). I think if you go to a tile store you may be able to find examples of both. That being said, there's also glass tile that isn't "clear" or "translucent" at all and isn't meant to be in which case you don't have any problems with having the thinset/mastic showing through - just something to think about.
