this stainless steel copper bottom handi, along with its lid, is usually dishwasher-safe. However, hand-washing is recommended to maintain its appearance and performance.
The product description should specify whether the handi comes with a lid or not. If it does, it is usually made of stainless steel.
The handi with a copper bottom is generally compatible with gas stoves.
It has a copper layer at the bottom for better heat distribution, but the rest of the cookware is made of stainless steel.
