Pyrex Model Numbers relevant to this site:

It may seem a bit clinical to refer to these pieces by number, but it is a precise and unmistakable way to convey which piece is being discussed.  The model number is usually found on the bottom stamp or occasionally under the handle.  For some lids the number should be on the rim, if not on the tab handle.                   

Lengthy names like ‘Oven, Refrigerator & Freezer Set’ and ‘3-Piece Bake, Serve & Store Set’ seem to be unhelpful identifiers since these names did vary over the years.  The ‘3-Piece Casserole Set’ was introduced as a ‘Cinderella Casserole Set’ in the late 1950s.  And similarly, what were known as Cinderella Bowls in the 1950s were called Mixing Bowls in the 1980s, and in the 1970s it was simply a Bowl Set.  Throughout these frequent name changes, the model numbers have remained constant.

472 – 1½ Pt Cinderella casserole (750ml)  Lid: 470

474 – 1½ Qt Cinderella casserole (1.5L)  Lid: 474
475 – 2½ Qt Cinderella casserole (2.5L)  Lid: 475

460 Set – 2 Cinderella casseroles marked 473, 474.  (aka:  2-piece Casserole Set)  The colour scheme is the same as that of the 480 set.  An uncommon set, it was made in four patterns for a short time in 1985.

470 Set – 3 Cinderella casseroles marked 471, 472, 473.  (aka:  3-piece Bake, Serve & Store Set)

480 Set – 3 Cinderella casseroles marked 473, 474, 475.  (aka:  3-piece Casserole Set)

484 Set – 1 Cinderella casserole marked 474, only the box is marked 484.  For patterns with alternating colour schemes, this item was made in the primary shade rather than the secondary shade.  Therefore it is possible to find 474s of the same pattern in both colours.

485 Set – 1 Cinderella casserole marked 475, only the box is marked 485.  This piece was decorated with the primary shade, just as it is when sold in sets of three.

501, 502, 503 – Refrigerator Dishes.  501 - 1½ cup, 502 - 1½ Pt, 503 - 1½ Qt  (aka: 4-piece Oven, Refrigerator & Freezer Set)


664 – 4 Qt Round Casserole.  A unique shape with no handles, but it has a sturdy wide rim, like a very large Margarine Dish.  Equipped with a smooth lid or one with a pebbled texture. 


943/043 - 1½ Qt Oval Casserole (1.5L)  Casserole is marked 043, lid is marked 943.  When sold as a covered casserole it is called a 943.‡

945/045 - 2½ Qt Oval Casserole (2.5L)  Casserole is marked 045, lid is marked 945.  When sold as a covered casserole it is called a 945.‡

963/063 - 1 Qt Oval Divided Dish; formerly called 1½ Qt.  The divided dishes that are Compatibles to Corelle always came with a decorated opal lid which is non-divided and is usually marked 945.  The dish itself is usually marked 063, and all together the set was sold as a 963, but this number appears only on the box.

‡  This is an old numbering convention that dates back decades to a time when all casseroles were offered with or without lids.  Open casseroles were identified by their own number, but covered casserole sets were identified by the model number of the lid.  This was particularly useful when two or more lid styles were made for the same casserole.
