Gibson Home Zen Buffet Hard Square 24-Piece Porcelain Dinnerware Set

I quite like the look and feel of the Gibson dinnerware, but I was shocked to discover that the dishes are not microwave-safe as advertised. I microwaved a dish for 1 minute at 80% power in my LG microwave and heard a cracking noise. Upon opening my microwave I saw that there was a crack running through the entire plate on both sides. On the back of the dish it clearly reads "microwave safe." This is obviously not the case. I am out of the return/refund window on these dishes, which I bought less than two months ago. IF YOU BUY THESE DISHES, THEY ARE NOT MICROWAVE SAFE.
