Glass, ceramic, and metal are the three most popular picks for bakeware, with metal being the obvious choice for baking sheets. Light-colored metal makes for even browning (darker metal can cause over browning), and aluminum is best at conducting heat and reliably produces evenly baked goods. Glass is also a good heat conductor and, unlike aluminum, it’s nonreactive. Ceramic’s attractiveness lends itself to stove to table desserts worthy of showing off.
