Just finished my backyard kitchen this morning. Fired up the egg to make pizza's for my daughter and her friends. Noticed that the granite slab where the egg was sitting now has a crack. Jeeze this is unexpected. I plan to call the grnite guys out for an opinion but the slab was well supported (flat concrete block with leveling compound poured on top. It was as smooth as you can get. I don't think there was an issue with the slab install. I asked my local dealer if it was OK to place the EGG directly on the granite and they said yes. Now I am wondering if I could have avoided this with something between the egg and the granite pad. Opinion and experiences are welcome.
