The Williams Sonoma Traditionaltouch™ Bakeware Essentials, Set of 6 pans are made from commercial-grade aluminized steel, and the cooling rack is chrome-plated steel.
You can expect even heating and consistent baking results for cakes, cookies, muffins, and other treats.
The pans are uncoated, so greasing or lining them is recommended for best results.
The cooling rack is a fixed chrome-plated-steel rack that allows air to circulate underneath to help keep undersides crisp.
Cooling rack measures 16 3/4" x 11 1/2" x 1/2" high.
