Kiln shelf durabilty?
After reading several threads about it, I am thinking of buying a kiln shelf for bread and pizza baking. I was wondering how durable it is - I haven't found any mention of it breaking and I assume people steam their ovens with it as well but I would just like to make sure before I spend the money. I had a pizza stone which broke after being first exposed to steam in the oven and want to make sure that this won't happen with a kiln shelf. For bread baking, I preheat the oven to 250°C with a tray in the bottom which already has some water in it, then just before the bread goes in, I pour some boiling water onto this tray. Would this ok with the kiln shelf? Thank you for your help.
