1937 Advertisement - Pyrex Ovenware & Flameware 

A page from the March 1937 issue of Good Housekeeping advertises the newest items in Pyrex and Flameware.  During early 1936 the first Flameware top-of-stove products appeared, a set containing two saucepans and a small skillet, plus a detachable handle.  In Pyrex ovenware, oval utility lids were also new in 1936 and were part of a new three-piece set.

In the Oval Baker Set, regular shallow and deep oval casseroles were paired with one flat-top utility lid that fits both.  The small set comprises an 042 shallow, 033 deep, and 602-613 lid.  Placing this lid on the 042 makes a 602 casserole, and on the 033 it is called a 613 casserole.  Pieces in the large set are: 043 shallow, 034 deep, 603-614 lid.  Using this lid with an 043 makes a 603 casserole, and with the 034 it is a 614 casserole.

Thick Flameware saucepans & skillets are: 832 (1 Qt), 833 (1½ Qt), 817 (7 inch).  Although these sizes were never sold with lids, they were designed to be used with ordinary round casserole lids that could be purchased separately.  A 623 lid fits an 833, and a 622 lid will fit 832 & 817.  A fourth saucepan size was added in 1945, an 834 (2 Qt), which takes a 624 lid.

There is a reason why Flameware skillets are so small.  During Flameware's development, Corning executives were adamant that a 10 inch skillet should be in the new product line since market research had determined that consumers were interested in that size.  But because the most modern stoves of the time had burners that were 8 inches or less, researchers found that the proposed pan would not heat evenly, frequently shattering due to the temperature difference.

Convincing management that a 10 inch Flameware skillet was impossible became another challenge.  To prove the point, a demonstration was arranged using twenty-one 10 inch skillets, each on a 6 inch burner.  A few minutes after the units were switched on, three of the pans exploded and it was decided immediately that smaller skillets should be produced instead.
