I always preheat dinner plates in the oven. Our daily dinner plates are stone ware, special occasion is china, all are oven proof. I never worry about how hot the oven is. I have never broken a plate by heating it in the oven.
We have never had any table damage putting the hot plates on just a tablecloth on the table. Sometimes dh uses place mats on top of the table cloth.
I have never used Corelle, I have no idea if you can put it in the oven, but as it is thin, I do not know how much heat it would hold.
I married into a family that never warms their plates. Every meal is pretty cold by the time it is plated and on the table. Yuck.
