I think all dishes should be made of really good quality glass. I have decided this because I hate that plastic and metal get microscopic scratches in them after each wash. It pains me to wash certain items, I honestly cringe as I do it. My once beautifully clear set of bottles is now murky looking. I want them to appear new and well taken care of for their entire life. My new Iced Tea maker pitcher...same deal. My nice Nambe silver platter...scratches! And if I use a very fine, soft towel, it doesn't do the trick, food residue it left on the dishes.
