Nope, none of the above. It has not been in the dishwasher, and sits on shelf with other PWs. it has not moved, in 6 months. I bought it 6 months ago, it came through the mail, I bought it online. The PW was nice, no cracks and very few if any scratches. But now, It is completly covered, in this peeling even the polished bottom looks like the rest. It has had the dust wiped off, with a damp cotton cloth, no soap a few times when dusting. I dont use any soaps, or adbrasives on any of my glass. It is only the outer layer that is cracked, and peeling. Thats why I thought it may have been sprayed to cover any marks. But now after seeing pics of crizzling, i do think that is what it is. And if I am reading right, it is a degradation process. It is caused by an inherent fault in the chemical composition of the original glass formula. Please let me know if this is correct ?
