Vintage Nacco - Copco dutch oven safe heat tolerance
I have a couple vintage (50-60's) enameled cast iron dutch ovens that I'd like to use for baking bread.
Does anyone know the safe heat tolerance of Nacco-Copco dutch ovens? I don't want to damage my inherited pieces. In looking at a variety of current dutch ovens, some top at 450°F and others at 500°F.
My recipe instructions: preheat oven & dutch oven 475°F, brush oil on bottom, add cornmeal, then dough. Generally, how long can an empty covered dutch oven stay in an oven safely?
