4.5 qt Ware Ever Air Bake insulated Casserole Glass-Lid and plastic lid too.

Based on the markings in your image, this is a WearEver Air Bake insulated casserole or baking pan. The specific instructions on the bottom provide a unique care requirement for this type of bakeware: Cleaning Instructions Dishwasher Safe: The pan is explicitly labeled as dishwasher safe. Do Not Immerse: This instruction is critical for insulated (double-walled) pans like yours. These pans use a pocket of air between two layers of aluminum to prevent burning and ensure even baking. The Risk: If you submerge the pan in a sink of water, liquid can seep into the air pocket through the small seams. The Consequence: Water trapped inside the walls can cause the pan to warp, rust internally, or even pop when heated in the oven as the trapped moisture turns to steam. Safe Washing Method: To clean it by hand, use a soapy sponge on the surface and rinse quickly under running water rather than letting it soak in a full basin. Type: 4.5 Quart (4.26 L) Insulated Casserole/Baking Pan. Material: Heavy-gauge aluminum, often featuring a non-stick interior coating.
