Pumpkin Pie

I made a pumpkin Pie in a 12 inch oven in a regular glass pie pan that didn't have those handles molded onto the rim. While I did use my generic Tractor Supply dutch oven because I didn't want to risk harming my Lodge Ovens, the Pie turned out really well. I did use a lodge trivet under the pie plate but it did turn out well. I've never seen the question addressed before: can heating up a dutch oven with so much dead air space harm the oven? Since I've done this twice now with the oven and it hasn't yet warped or cracked I am thinking that you might get away with this sort of thing once in a while. The question is how safe is this with a dutch oven? I'd love to hear Bob Henry chime in as well as others have have been using cast iron much longer than me.
