Corning introduced the pretty Shadow Iris pattern in 1986. It was available in their Corelle dinnerware and kitchen accessories line as well as their Corning cookware and baking/serving pieces. These are the two largest size casserole or baking dishes in the Shadow Iris line - 5 quarts or liters (sometimes called a Dutch oven) number A5B, and 3 quart number A3B. The large dish is 10 inches diameter (12 inches across the handles) by 4" deep to the rim. The 3 quart casserole is 8-1/2" diameter, 10-1/4" wide across the handles, and just a shade under 4 inches high to the rim.

Both baking dishes come with their appropriate Pyrex glass lids. There are no chips, flakes, or damage to either the casseroles or the lids. They're super clean with only very faint, minimal marks on the bottoms from use and storage. See my other listings for a smaller size pair of Shadow Iris casserole bakers (shown all together in the last photo).
