Pyrex Model Numbers, Shapes & Capacities

It might seem clinical to refer to bowls & casseroles by number, but it is a precise and nearly unmistakable method of identifying them.  The model number is usually found on the bottom or occasionally under the handle.  For lids, the number should be on the rim, if not on the tab handle.  Disregard the mould number, it is never useful.

Lengthy names like "Oven, Refrigerator & Freezer Set" and "3-Piece Bake, Serve & Store Set" are less helpful identifiers since these names did vary over the course of the product's lifetime.  The "3-Piece Casserole Set" was introduced as a "Cinderella Casserole Set" in the late 1950s.  What were known as Cinderella Bowls in the 1950s were just a Bowl Set in the 1970s, and Mixing Bowls in the 1980s.  Throughout these frequent name changes, the model numbers remained constant.

72 - Butter Dish
75 - Margarine Dish
77 - Gravy Server
770 - small footed bowl with a 1 cup capacity
1410 - 9 oz Pyrex mug.  Newer ones, mid to late 1970s onward, are marked 300 ml.

Nesting Bowls:

401 – 1½ Pt Round bowl (750 ml)
402 – 1½ Qt Round bowl (1.5 L)
403 – 2½ Qt Round bowl (2.5 L)
404 – 4 Qt Round bowl (4.0 L)

441 – 1½ Pt Cinderella bowl (750 ml)
442 – 1½ Qt Cinderella bowl (1.5 L)
443 – 2½ Qt Cinderella bowl (2.5 L)
444 – 4 Qt Cinderella bowl (4.0 L)

300 Series – 3 Round nesting bowls marked 401, 402, 403
400 Series – 4 Round nesting bowls marked 401, 402, 403, 404
440 Series – 4 Cinderella nesting bowls marked 441, 442, 443, 444

Cinderella bowls were never sold in a set of 3.

7401 – 1½ Pt Clear Round bowl (750 ml)
7402 – 1½ Qt Clear Round bowl (1.5 L)
7403 – 2½ Qt Clear Round bowl (2.5 L)
7404 – 4 Qt Clear Round bowl (4.0 L)

These clear Pyrex bowls are an exact copy of opal 400-series bowls.  Their exact introduction date is not known, but backstamps show that they are from the late 1970s or 1980s.  This shape gained a sculptured exterior in the 1990s, but the model numbers for sculptured bowls are suffixed with "-S".

322 – 1 Qt Rimmed nesting bowl (1.0 L)
323 – 1½ Qt Rimmed nesting bowl (1.5 L)
325 – 2½ Qt Rimmed nesting bowl (2.5 L)
326 – 4 Qt Rimmed nesting bowl (4.0 L)

Without a "324" this numbering scheme seems counter-intuitive, but really the numbers of the first three bowls make perfect sense.  When this bowl shape was introduced in 1942, it was a three piece set only.  The last digit is not meant to be sequential, it represents the bowl's capacity in quarts multiplied by two.  The largest bowl was added later, but instead of "328", it was named with the next sequential number.

Casseroles:

471 – 1 Pt Cinderella casserole (500 ml)  Lid: 470
472 – 1½ Pt Cinderella casserole (750 ml)  Lid: 470
473 – 1 Qt Cinderella casserole (1.0 L)  Lid: 470
474 – 1½ Qt Cinderella casserole (1.5 L)  Lid: 474
475 – 2½ Qt Cinderella casserole (2.5 L)  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, the box is marked 484.  For patterns with alternating colour schemes, this item was decorated with 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, 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.  They were equipped with clear Pyrex knob-top lids.  Some lids have a pebbled texture, while others are smooth.

043 - 1½ Qt Oval Casserole (1.5 L)  Lid: 943.

045 - 2½ Qt Oval Casserole (2.5 L)  Lid: 945.

063 - 1 Qt Oval Divided Dish; formerly called 1½ Qt.  Divided dishes that are Compatibles to Corelle always came with a decorated opal lid which is non-divided and 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.  Older divided dishes are not always marked with a model number.

For 043, 045, 063, the last digit of the model number represents the item's capacity in quarts multiplied by two.

022 – 1 Qt Round-bottom casserole (1.0 L)  Lids: 622, 682.
023 – 1½ Qt Round-bottom casserole (1.5 L)  Lids: 623, 683.
024 – 2 Qt Round-bottom casserole (2.0 L)  Lids: 624, 684.
026 – 3 Qt Round-bottom casserole (3.0 L)  Lids: 626, 686, 687.

The last digit of the model number represents the casserole's capacity in quarts multiplied by two.  Two types of lids were available: lids numbered 62_ have a single knob on top, and those numbered 68_ are flat-top utility lids with tab handles.  With a pie plate shape, utility lids were designed to be useful as an extra baking dish.  For the 026, a very deep 687 roaster lid with a capacity of 2¼ quarts also was available. 

In clear Pyrex, this round-bottom style debuted in 1950.  In 1952 the 024 became the first size to appear in opal Pyrex, but the 026 is found in clear Pyrex only.  An 8 oz size, an 080 with a 980 lid, appeared briefly in the mid 1950s.  Although casseroles with this same range of model numbers and sizes had existed since 1926, these were old-fashioned shapes instead with straight sides and small handles.  One more size, a 1 pint 021, can be found in this older style.
