1922 Leaflet - There are now 100 Pyrex shapes and sizes 

Front Cover 1922 Pyrex leafletThis leaflet was issued in January 1922 to inform consumers of the newly expanded range of Pyrex ovenware.  It is the type of brochure that a retailer might hand out to shoppers at the sales counter.  All of the new products had been on the market since mid 1921, and did not launch on January 1 1922 exactly.

This leaflet does not indicate specifically which items are new.  A few were additional sizes of existing shapes, while others were entirely new products.  Previously, the variety of Pyrex shapes & sizes had amounted to more than 50, so the 100+ items listed here represent a substantial increase.

Other new additions to the product line in 1921 were White Pyrex and Iridescent Pyrex, but they are not addressed in this leaflet.  Pyrex baby bottles and teapots were introduced later in 1922, so they are not listed here either.

When Pyrex was first introduced, it experienced impressive sales results, but by the early 1920s demand had dropped off.  Endeavouring to boost interest in the product, the company showered consumers with more product choices and lowered retail prices.  Despite this effort, sales continued to diminish.

Eventually Corning would engage an advertising agency to advise on effective methods of marketing Pyrex.  The agency reasoned that too many choices increase manufacturing costs and often confuse the customer.  So shortly after the product line was doubled, it was streamlined by discontinuing almost as many.  Particular attention was paid to "competing" items that were only slightly different from others, like casseroles in the same general size & shape, and pie plates that were practically the same diameter.

Price list and descriptions on the other side.

The following images are a modified version of the leaflet.  In its original form, it is a complicated document to interpret; the illustrations are not presented in the same order that the price list is, and in many cases different terminology is used to describe the same item.  So for clarity, the information below is organized into segments, with model numbers, sizes, shapes, and prices listed alongside the picture of the product.  The dimensions that are provided for certain items are outside measurements, sometimes including the handles.

 

Pyrex round & oval covered casseroles
Casseroles, Round & Oval, Shallow & Deep.

New sizes in 1921 are: 113, 169, 170, 185, 190.  Casseroles numbered 167 to 170 and 190 to 197 were often called "Standard", meaning that they are designed to fit "standard mountings", i.e.: a metal frame or stand.  They have a thick, sturdy ridge under the rim for supporting itself on the stand.

It seems that round casseroles numbered 100 to 104 and 112 & 113 were not ideal for this use, but metal ware manufacturers did make frames and cradles for these shapes, and for shallow ovals too.  By 1924, the 100 to 104 series was discontinued.


  

Pyrex casseroles with Victor covers, plus bean pots
Casseroles with Victor Covers, Round & Oval, plus Square, and Bean Pots.

Victor covers were a new item in 1921.  When a Victor cover is added to a casserole, the first digit of its model number changes from "1" to "2".  The casserole itself is stamped with both model numbers, since it is the same piece as before, just with a different lid.

Square casseroles (800) also were new in 1921, and came in only one size, and with one type of lid.  Two bean pot sizes, 502 & 504, had been offered since 1916.  A 502 was called a Petite Marmite and it is meant to be an individual soup pot.  The larger 506 bean pot was a new addition in 1921.


  

Pyrex baking pans, loaf, biscuit, round & square cake, rectangular utility dish
Baking Pans.

Recently introduced in 1921, a round shallow cake pan (220) has a larger diameter than a round standard pan (221).  Biscuit pans (234 & 235) and square cake pans (809 & 810) were also new items at that time.


 

Pyrex round, oval & square pudding dishes
Pudding Dishes or Open Baking Dishes.

Most pudding dishes are lidless casseroles.  The 120 to 124 pudding dishes correspond to 100 to 104 casseroles.  Those suffixed with "B" are identical to casseroles of the same number, but the actual item is not marked with a "B".  A 132 pudding dish could be an uncovered 112 casserole, but a 155 pudding dish and a 113 casserole might not be exactly alike.  

A 450 pudding dish (new in 1921) and those numbered 463 to 467 are single-purpose items and are not meant to have a lid.  Both 463 & 467 were also new items at that time.  The 450 was replaced in 1925 by 627 & 628 handled casseroles sold without their lids.  The 463 to 467 series was dropped around 1926.


 

Pyrex baking dishes, oval two-piece, two compartment dish, round shallow, oblong pudding, round & oval with handles
Other Baking Dishes.

The 110 covered two-piece oval baker debuted in 1921.  Its lid functions as an extra baking dish.  The 130 round two-compartment divided dish was also a new item, and both 110 and 130 remained up to 1938.

A 135 round shallow dish is not a cake pan, and similarly, the 145 oblong pudding dish is not a loaf pan.  Both of these were new items in 1921, but they were dropped sometime between 1925 & 1927.

Round dishes with handles (301 & 302) were sometimes called shirred egg dishes.  Although the 322 oval dish with handles had been called an au gratin dish in the past, by this time, a new shape had taken that name instead.

At this point, 302s have small flat handles that are level with the rim, which is also true of 301s & 322s.  The 301, 302 & 322 were dropped about 1925, but the 302 returned in the late 1920s with a new shape.  It was updated with larger upturned handles that resemble those of French au gratin dishes (330, 331, 332).


 

Pyrex au gratin, oval shallow, individual pie dishes, round & hexagonal pie plates
Individual Baking Dishes and Pie Plates.

French au gratin dishes (330, 331, 332) have larger handles and are longer and narrower than an oval dish with handles (322).  It seems that the two larger individual pie dishes (453 & 455) became unavailable after 1922, but they would return by 1929.  The smallest (452) was dropped in 1938.

A series of six pie plates with a wide flat rim was introduced in 1921.  A seventh size (205) appeared in 1924, but 206s & 207s were dropped about 1926.  Until 1921, only one pie plate (201) had been available in this shape and it is identical to a 209 in the new series.

Narrow-rimmed 202 & 203 pie plates were an older item and would be discontinued shortly.  Hexagonal pie plates are numbered 1203 here, but by 1924 their model number would be changed to 200.


 

Pyrex platters, trays & custard cups
Platters, Trays & Tiles, Custard Cups.

Oval platters in two sizes were a new product in 1921.  A 706 tile & 708 tray also had been recently introduced, and French custard cups in two sizes were new items too.  A 425 (5 oz) arrived in 1932, but by that time they were called deep custard cups instead.  Oval custard cups (427) were made in just one size.


 

Pyrex ramekins, bell-top dish, percolator tops
Ramekins and Special Items.

Small 432 ramekins would be discontinued shortly.  Mushroom dishes are comprised of a regular 301 or 302 round dish with handles and a bell cover. 

Percolator tops were a replacement part for coffee pots from other companies, as there were no Pyrex percolators at this time.  The design for the "Pyrex style" top was filed with the patent office in May 1914, one full year before the introduction of Pyrex ovenware.  It is the oldest Pyrex product destined for consumers, supplied to firms that manufactured percolators.  Casserole lids with the same hollow pointy-top knob were conceived afterwards, their design almost certainly based on this percolator top.
