My 2 cents…While new to baking I had done a lot of research to select a stone. I’ve learned that you should never put a cold stone in a hot oven (heat the oven with the stone in it), it is safe to leave the stone in the oven at all times and that you need to be careful not to spill food (especially fats) onto the stone as that is the cause of odor etc.
All that being said I had decided to purchase this stone. It’s big, thick and shipped in a couple of boxes including the outside box that is HUGE and packed with peanuts etc. I have been very satisfied with this purchase.
BTW I do take the stone out of the oven after it has cooled down after baking on it.
I hope some of this helps.
