Vintage White Porcelain Pie Bird, 4" Tall

Vintage White Porcelain Pie Bird, 4" Tall. This is a white porcelain pie bird, a collectible kitchen item also known as a pie vent or pie funnel. Function: It is placed in the center of a double-crusted pie to allow steam to escape through its hollow body and beak while baking, preventing the filling from bubbling over. Design: The bird's shoulders also help support the top crust, preventing it from sagging into the filling. Material: The item in the image is made of glossy white ceramic or porcelain.
