I bake with glass pie plates and have a few ceramic ones as well. So many recipes will have you start at a higher temperature, then lower after 15 minutes. I was always adjusting the time and temperatures until I followed a fruit pie recipe from a Maine cookbook. The author baked all her fruit pies at 350 for 60 minutes. My pies, whether berry or apple, bake perfectly, the top crust puffs up and is flaky. and the bottom crust browns. The filling is always bubbling and sometimes I let it set in the oven after turning it off. My oven is electric and I use the middle rack. May take longer in a pan larger that 9-10 inches or deeper.
