Glass lids used in non-stick coating pressed cookware set with vented glass lids, especially those with vented features, should meet several performance requirements to ensure safety, durability, and effective functionality. Here are some key performance requirements:

Heat Resistance:

Glass lids should be able to withstand high temperatures commonly used in cooking without cracking, shattering, or warping. This is particularly important for cookware with non-stick coatings, as the lids are often used during various cooking methods, including oven use.

Durability:

The glass used for the lids should be durable and resistant to scratches, chips, and impacts. Cooking environments can be harsh, and the lids should maintain their integrity over time.

Vented Design:

If the lids have vents, these vents should be designed to release steam gradually to prevent pressure buildup while cooking. This feature helps to avoid lid rattling and promotes efficient cooking. The venting mechanism should be durable and easy to open or close.

Tight Seal:

The lids should provide a tight seal to trap heat and moisture during cooking. A well-fitting lid enhances the efficiency of the cookware and contributes to better cooking results.

Cool-Touch Handles:

If the lids have handles, these handles should remain cool to the touch during stovetop cooking. This ensures safe handling without the risk of burns.

Compatibility with Cookware:

The glass lids should be designed to fit securely on the corresponding cookware in the set. The fit should be snug to prevent steam and heat from escaping and to maintain optimal cooking conditions.
