Hi All, I am not sure if I am too picky or what. I just complete my kitchen remodel recently, but find there are uneven color issue on my glass backsplash. I asked my contractor to understand the reason, and he got back to me that this is tile manufacturing issue. The thermal expansion rate between white back and glass is different, so thru time-being, especially for tiles close to oven and stove will even worse. Is this true? I am afraid my kitchen will become ugly soon. Look forward to understanding the root cause of this issue and anyway to fix it. Thanks all.
