My stove... Which I run at night, is a Vermont castings vigilant.... Anyways I do cook, quite often on top of it... I have been wondering... About using the inside as an oven. Say let it. Burn to coals, then insert a pot, to cook say stew, bake a pizza ect... All my cooking pans are cast iron... Haven't got any iron pots... Would those be safe to set inside the stove for a bit? Say 20 min? I know that's a long time inside but what would be safe ?
