Use the glass lids for cooking and serving, and the plastic lids for storage.Limited One Year Warranty- Corning Ware® stoneware bakeware.Almost all of the pieces are back to their shiny state.But there are some stains that are so stubborn I'm not sure how to clean.

Handle hot stoneware items with a dry cloth or potholder.
Do not use to microwave popcorn or to hold or support popcorn bags, microwave convenience foods with special browning wrappers, etc. Do not use or repair any item that is chipped, cracked or severely scratched.
