A glass pie plate has the advantage of being transparent so bakers can quickly see whether the bottom of the pie crust is done. Unlike metal pie plates, glass pans conduct heat more slowly, so they are very suited to slow cooking pies e.g., fresh fruit pies. Unlike metal pans, glass pie plates can shatter when exposed to high temperatures changes so use caution if putting a frozen pie directly from the freezer into the oven. Ceramic pie plates are very attractive and come in lovely colors and decorative shapes. Like glass, ceramic pie plates heat up slowly so are better suited for pies which need more time to cook. It is important to check the manufacturer's instructions before using a ceramic pie dish in the freezer, oven or broiler as not all brands are safe to use under different temperature scenarios and may shatter. Metal pans are hugely popular because metal heats up quickly creating a beautifully flaky, golden crust. The speed of heating makes metal pies better for pies that cook quickly like pumpkin pie or Canned Peach Pie where a faster bake time works. Metal pans have the added advantage of being safe to go from the freezer to the oven and thus are very suitable for pies which are made ahead and frozen.
