I have had my braiser for less than two weeks and there are a lot of hairlines cracks like crazing showing on the bottom already. I have followed the instructions to preheat in low (in my case the lowest heat setting for 10 mins) then slowly increase to no higher than medium but this is happening in less than two months. My other pieces did not do the same, so I’m not sure if this is a defective piece or the lighter color pots and pans tend to do this. This is b grade item but still it shouldn’t like this.....
