Pyrex Model Numbers, Shapes & Capacities
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.
 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 300ml.
Nesting Bowls:
401 – 1½ Pt Round bowl (750ml)
402 – 1½ Qt Round bowl (1.5L)
403 – 2½ Qt Round bowl (2.5L)
404 – 4 Qt Round bowl (4.0L)
441 – 1½ Pt Cinderella bowl (750ml)
442 – 1½ Qt Cinderella bowl (1.5L)
443 – 2½ Qt Cinderella bowl (2.5L)
444 – 4 Qt Cinderella bowl (4.0L)
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
There is no evidence that Cinderella bowls were ever sold in a set of 3.
7401 – 1½ Pt Clear Round bowl (750ml)
7402 – 1½ Qt Clear Round bowl (1.5L)
7403 – 2½ Qt Clear Round bowl (2.5L)
7404 – 4 Qt Clear Round bowl (4.0L)
These transparent Pyrex bowls are an exact copy of opal 400-series bowls. It is not known when they were made exactly, but their backstamps show 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 (1.0L)
323 – 1½ Qt Rimmed nesting bowl (1.5L)
325 – 2½ Qt Rimmed nesting bowl (2.5L)
326 – 4 Qt Rimmed nesting bowl (4.0L)
Without a "324" this numbering scheme seems counter-intuitive, but actually 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.
Blue Ribbon 322 rimmed nesting bowl, this pattern is from the early 1990s.
Casseroles:
471 – 1 Pt Cinderella casserole (500ml) Lid: 470
472 – 1½ Pt Cinderella casserole (750ml) Lid: 470
473 – 1 Qt Cinderella casserole (1.0L) 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, 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.
Cinderella Casseroles: Pink Gooseberry 473, Sandalwood 471.
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.
043 - 1½ Qt Oval Casserole (1.5L) Lid: 943.
045 - 2½ Qt Oval Casserole (2.5L) Lid: 945.
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.
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 (1.0L) Lids: 622, 682.
023 – 1½ Qt Round-bottom casserole (1.5L) Lids: 623, 683.
024 – 2 Qt Round-bottom casserole (2.0L) Lids: 624, 684.
026 – 3 Qt Round-bottom casserole (3.0L) 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 ounce 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 for decades prior to 1950, 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.
