1940s

Multi-colour bowls (1945)

This set is the first consumer product to be made from opal Pyrex, and full-scale production began in September 1945.  At some point before 1949, the 404 became available for individual purchase in yellow, plus a new colour, red.

Red 402s & 404s of earlier manufacture are a lighter orange-red colour, but this evolved to a darker true red shade.  The other three colours also varied a bit over the lifespan of this set.  Multi-colour bowls in blue, red, green & yellow and the single red 404 were marketed until 1968.

The shape of 400-series bowls was altered about five years after their debut.  Older examples have a highly-arching well-defined foot, and the bottoms of newer ones are much more flat.  Once this new shape was established it remained practically unchanged for decades.

Red 404.  It does not belong to any four-piece bowl set; Red 404s were always sold individually.

Markings vary a lot on the oldest bowl sets, and through the first few years backstamps accumulated more details, adding the model number, the "Made in U.S.A." statement, and the capacity.  But the most consistent features of 400-series bowls from the 1940s are the substantial foot on the bottom and the orange-red colour of the 402.

 

Red 404s with different bottoms
Red 404s:  The foot of the older bowl (left) is more pronounced.  A flat bottom (right) is the more typical shape for 400-series bowls.  The colour difference is visible too.

From 1945 to 1950, advertisements rated the capacities of 400-series bowls at 4 Qt, 2¼ Qt, 1¼ Qt, 1 pt (or ½ Qt).  Following this was a period where their volumes were not mentioned at all, then beginning in 1953 they were described as 4 Qt, 2½ Qt, 1½ Qt, 1½ pt.  For 401s, 402s & 403s, it seems like a 1 cup increase, but their actual sizes had not changed.  Older thicker bowls and newer thinner bowls both hold the larger quantities equally well, filled to the very top.


Multi-colour refrigerator set (1948) 

This set includes two red 501s (1½ cup), one blue 502 (1½ pt), and one yellow 503 (1½ Qt).  Although it was emphasized that the dishes were suitable Pyrex Refrigerator Dish set, image from 1956 advertisementfor absolutely any purpose, the 502 was ideally designed to hold one pound of butter and to be held easily in an average woman's hand.

Multi-colour refrigerator sets remained in production into the 1960s.  Clear 501s & 502s were sold individually, beginning about 1949 and remaining for only a few years.


Red Tulip: Decorated Clear Pyrex (1948)

Red Tulip patternClear Pyrex items with a red & green tulip design on a frosted band were introduced in September 1948.  The product line was still offered during 1949, but otherwise this unique method of decoration seems to be short-lived.  In advertising it was described as: "… so inexpensive and practical.  Decorated with frosty borders of dainty red tulip and green leaf designs, it will add a cheery note to any kitchen."  The frosted/etched surface allows the coloured stain to adhere better to the glass.

Red Tulip was available on: three round casseroles with pointy knob-top lids (022/622, 023/623, 024/624); two custard cups (462 & 465); square cake pan (222); loaf pan (212); rectangular utility dish (232); rimmed nesting bowl set (322, 323, 325).  Visit the Corning Museum of Glass for a photo of a Red Tulip 023/623.


Hostess sets: Red, Yellow (1949) 

Hostess bowls are characterized by their square circumference and round base.  Introduced summer 1949, a large Hostess set comprised one 2½ Qt serving bowl and four 12 oz ramekins.  The small set did not debut until 1950, with one 1½ Qt serving bowl and four 7 oz ramekins, and this set Red: 7 oz & 2.5 Qt;  Yellow: 12 oz & 1.5 Qt with lid.generally included a lid. 

(Photo: Red 407 (7 oz); Yellow 410 (12 oz); Yellow 015 (1½ Qt), with 515 lid; Red 025 (2½ Qt).)

All four sizes were sold individually too, and serving bowls could be purchased with or without lids.  With a lid, they were called casseroles.

Red & Yellow Hostess bowls were discontinued autumn 1953, but the shape was resurrected spring 1959 for a turquoise chip & dip set.  Rose-coloured 2½ Qt Hostess bowls with lids also exist, but their exact age and official name are uncertain.  The colour is different from the usual Pink or Flamingo products.
 

 
1950s 

Princess dinnerware (1952) 

Made of opal Pyrex, Princess dinnerware was available during 1952 & 1953.  A deeply embossed ripple design on the rim gives it a thin and delicate appearance.  One advertisement called it a "gadroon edge".  The brand name on the backstamp is Corning, and most pieces are also marked with "Toughened ... Heat-Resistant" and a five-pointed crown logo.

Princess cup & saucerPrincess was sold in 20-piece sets with four place settings, including: dinner plate, side plate, cup & saucer, soup/cereal bowl.  These five pieces plus a dessert bowl could be purchased in open stock too.

This product is closely related to tableware produced in Cremax and Monax during the late 1930s & early 1940s.  The shape & size of Princess plates, bowls and saucers is borrowed from Oxford and the plain ribbed "piecrust" pattern, but Princess cups are a new design.  Some pieces carry no brand name at all, and are marked only with concentric rings and "Made in U.S.A.", just as Cremax and Monax products had been.


Lime, Flamingo bakeware (1952) 

First appearing autumn 1952, these solid-coloured pieces include: 024 round casseroles, 209/909 pie plates, 221 cake pan, 222 square pan, and 232 rectangular pan.  More sizes were added in 1954: 080 round casserole, 212/213 loaf pans, 231 rectangular pan.  Lime bakeware was dropped during early 1956, and Flamingo bakeware was discontinued in 1957.

Desert Dawn bakeware: Desert Pink, Desert Yellow (1955) 

These solid-coloured pieces with a speckle effect include: 024 round casserole, 213 loaf pan, 209 pie plate, 221 cake pan, 222 square pan, and 231 & 232 rectangular pans.  Individually, the two colour choices were named Desert Pink and Desert Yellow, and both were available about two years.

Pink bowls & bakeware (1956)
Turquoise bowls & bakeware (1956)
 

These solid-coloured pieces include: 023 & 024 round casseroles, 213 loaf pan, 209 pie plate, 221 cake pan, 222 square pan, 231 & 232 rectangular pans, 300-series & 400-series nesting bowl sets, and 500-series refrigerator sets.  The 300-series bowl set and 024 casserole remained until early 1963, but the other shapes & sizes disappeared in the late 1950s.


Pale Yellow bakeware (1956) 

These solid-coloured pieces include: 023 & 024 round casseroles, 213 loaf pan, 209 pie plate, 221 cake pan, 222 square pan, and 231 & 232 rectangular pans.  The 024 casserole remained until early 1963, but the other shapes & sizes disappeared in the late 1950s.

Daisy: Pink (1956)
Snowflake: Charcoal, Turquoise, Opal/Turquoise (1956)
 

Arriving late 1956, these four colour and pattern choices also represent the debut of oval 043 & 045 casseroles.  Initially dubbed "Decorator Casseroles", they are the first opal Pyrex products to have a printed pattern.  More shapes & sizes in these patterns arrived later: Space Savers (1957), divided & non-divided dishes (1958).

Charcoal with White Snowflake was the first to be discontinued, about 1960, and Turquoise with White Snowflake remained the longest, up to 1967.  Pink with White Daisy and Opal with Turquoise Snowflake were dropped during early 1963.

Space Saver Casseroles (1957) 

Appearing early 1957, these rectangular casseroles were available in two sizes.  A 548 (1¼ Qt) is more shallow than a 575 (2 Qt), and a 550 lid fits both of them.  Either size could be purchased individually with a clear Pyrex lid.  Both sizes were also offered together in a 550 set with one Pyrex lid (550-C) and two flat metal lids (550MC).  The latter were provided for freezer storage, and were meant to be sealed with freezer tape to be air-tight.

When Space Savers debuted, they were decorated with each of the four Snowflake and Daisy variations, co-ordinating with oval Decorator Casseroles.  Golden Acorn arrived in 1960.  Space Saver casseroles had a short lifespan, and were discontinued during early 1963.

Bright Yellow bowls (1957) 

This shade of yellow is unique, and it was available only on 300-series & 400-series nesting bowl sets.  It does not match the yellow 404 of the regular multi-colour set.  The all-yellow 300-series set remained until early 1963, but the 400-series set disappeared in the late 1950s.

Family Flair dinnerware (1957) 

There were five patterns to choose from when this coupe-shaped dinnerware was introduced: Field Flower, Pine Cone, Chinese Grass, and Quince which was Sea Isle saucer, Yellow Petal sugar bowl lid.available in Pink or Yellow.  Within one year Field Flower and Pine Cone were dropped and the remaining patterns were re-named.  Quince became Pink Petal & Yellow Petal, and Chinese Grass became Sea Isle, which is turquoise.

(Photo: Sea Isle saucer, Yellow Petal sugar bowl lid.)

Dinner plates, side plates, saucers and oval platters are patterned, and cups, soup/cereal bowls and oval serving bowls are solid-coloured.  Creamers & sugar bowls are also solid-coloured, but sugar bowl lids are patterned.  Family Flair was sold in 20-piece sets comprising four place settings.  The product line was available for two or three years.


Butterprint: Turquoise (1957)
Gooseberry: Pink, Yellow/Black (1957)
 

Introduced late 1957, these three colour and pattern choices also represent the debut of 440-series Cinderella bowls.  Turquoise Butterprint remained in production until 1968, while Pink Gooseberry was discontinued about 1966, and Yellow & Black Gooseberry was dropped in 1962.

Also in turquoise Butterprint are round nesting bowls, sold in 400-series sets and 300-series sets, each bowl having a white background.Turquoise Butterprint 501 refrigerator dish  Butter dishes in this pattern first appeared about 1960.  Refrigerator dishes are also white-bodied and were offered in turquoise Butterprint and pink Gooseberry, the latter set not arriving until 1961.

(Photo: Turquoise Butterprint 501 refrigerator dish.)

Butterprint sets with special colour schemes also exist, each piece having a white background instead of using alternating colours: orange 440-series bowls, turquoise 440-series bowls, pink 470 casserole set, and turquoise 470 casserole set.

Divided Serving Dish, Oval Open Baker (1958) 

They are basically the same, but one is divided and one is not.  When divided dishes and open bakers debuted, they were decorated with each of the four Snowflake and Daisy variations, co-ordinating with oval Decorator Casseroles and Space Savers.  Golden Acorn arrived in 1960.  Divided dishes branched out with numerous other patterns and remained until 1976, but the non-divided oval baker was dropped during early 1963.

The oval baker's model number is 053, and 063 signifies the divided dish, but except for those produced in the mid 1970s, the numbers do not appear on these sizes.  In 1962, 063s were altered by adding an indentation across the base that mirrors the division across the interior.  Older 063s lack this feature and their bottoms are identical to that of an 053 non-divided dish, which might explain why the model number is absent from both.

Depending on the pattern, 063 divided dishes were equipped with either a plain clear divided lid; a non-divided decorated lid, either clear or opal; a plain clear non-divided lid; or no lid at all.  Typically, no lid was provided with the 053 oval open baker, which is why it is called "open", but in two or three special sets it could be purchased with a lid as a covered casserole.  All lids fitting 053 & 063 are marked 945, whether the lids are divided or not.


Cinderella Casseroles (1958) 

The small 470 set appeared in November 1958, consisting of a 471, 472 & 473, with a choice of pink Gooseberry or turquoise Butterprint.  The larger sizes, 474 & 475, did not arrive until 1961 when they were combined with a 473 in a 480 set.

Most, but not all Cinderella bowl patterns also can be found on Cinderella casseroles.  Most notably, casseroles were not marketed in Yellow & Black Gooseberry, and in Sandalwood only a 470 set was offered.  Numerous other patterns also exist in Cinderella casseroles.

Corning Crown Dinnerware (1958)

1958 saw the launch of a new selection of opal Pyrex dinnerware, named Corning Crown Dinnerware.  An alternative marketing approach was used, and for about two years the product line was distributed by door-to-door salespeople.  The gold trimmed version was named Gold Tipped, and platinum trim was available too.  Presumably the latter was called Platinum Tipped.  Some pieces are branded as "Corning Crown" with a three-pointed crown logo, while others are marked "Corning Dinnerware" without a logo.  Boxes were printed with the full name, "Corning Crown Dinnerware".

Sets contain four place settings of: dinner plate, soup/cereal bowl, cup & saucer.  Dessert bowls and a cream & sugar set also could be purchased.  Bowls and saucers are coupe, and dinner plates have wide flat rims.  The cream & sugar set's shape is borrowed from the earlier line of Pyrex Dinnerware that included Lime, Flamingo, etc.  The pointy-handled cups resemble cup styles produced by Corning's MacBeth-Evans division in the late 1930s & early 1940s.  A matching gold-trimmed 400-series bowl set was also named Gold Tipped and the Corning Crown brand name appeared on its packaging too.

Scallop Burgundy sampleAnother decoration that seems related is Scallop Burgundy.  It also includes pointy-handled cups and coupe bowls.  But an even greater selection of pieces can be found in this pattern, equivalent to all shapes & sizes that were manufactured in Lime & Flamingo dinnerware, excluding cups.  Markings on some Scallop Burgundy items are identical to those of Platinum & Gold Tipped, but many examples carry no backstamp or brand name at all.
