pizza stone cracked tonight - thought those things were supposed to withstand HIGH heat (isn't that the point? so you can achieve a crispy crust?). a big side chunk of the stone just split off as i pulled out pie no. 1 ... am going to take that as a good omen. but seriously, i didn't even realize this was a possibility. my oven was cranked to 500 for an hour beforehand (with stone inside), and then at the end i upped the heat a tad by turning on the broiler. Has this ever happened to anyone else in food52land?
