Cookware sets with metal lids

Metal

— a metal lid is more durable than a glass one and better withstands impacts, temperature changes, and active use in the kitchen. It's well-suited for boiling, stewing, simmering, and situations where it's important to reliably retain heat inside a pot, saucepan, or frying pan.

The downside is that you can't see the contents through metal, so you have to lift the lid to check the dish.
