No idea how people are washing them no chips here
I have 5 elderly cats and use 10 of these per day. Have had mine for a couple of years and only one has a chip where I dropped it in the sink. I have been a lab tech for 30 plus years and do a lot of washing up of glassware. I have absolutely no idea how you people are chipping and cracking these bowls unless, of course you are stacking them, or filling the sink with China/ dropping them. I wash these by hand and in the dishwasher, absolutely no problem. Cats get a clean one for every meal
