Does the pyrex P- 41 GC glass lid fit 1 and three quarter cup corningware petite casserole?

I cannot give you a definitive answer. Here's why:

* Pyrex and Corningware are different brands. While they both make oven-safe glass, their specific sizes and designs can vary.

* Specific Dimensions: To know if the lid fits, you'd need the exact dimensions of both the Pyrex P-41 lid and the Corningware Petite Casserole.

My suggestion:

* Check the packaging: Both the lid and the casserole should have dimensions listed on the packaging.

* Look online: Search for the products online and see if product descriptions or reviews mention compatibility.

* Contact the manufacturer: Reach out to Pyrex or Corningware customer support for clarification.

Good luck finding the perfect fit!
