Clear Pyrex 1915 to 1950: Casseroles 

The handles, lids and knobs of Pyrex casseroles follow a clear evolution from 1915 to 1950.  It is possible to group these shapes into date ranges and establish the approximate age of these items by recognizing the style of these features.  The peculiar pointed knob that is commonly associated with older Pyrex was used from 1915 to 1948 on about 40 different lids, so focusing on this aspect alone is an imprecise method of identifying a casserole or determining its age.

Other Pyrex products might have handles that resemble the handles of certain casseroles, but their production dates are not necessarily the same.  Details on this page are pertinent only to casseroles, pudding dishes and bean pots.  Also see: Baking Pans, Pie Plates.

 

Scalloped handle, Plain tab handle, Sculptured handle.
Casseroles (l-r): Scalloped handle 1926-1939, Plain tab handle 1939-1947, Sculptured handle 1947-1950.  Casseroles with no handles are from 1915-1926.

Model numbers are an important aspect in identifying Pyrex shapes & sizes.  They are normally three digits and can be difficult to find on very old Pyrex.  Some have no numbers at all, but those without handles are often marked under the rim or on the edge.  Running a finger around the rim is the easiest way to locate these markings, and reading them is best done under the glare of a bright light.Clear Pyrex 135 round shallow baking dish

Even when the model number is clearly visible on the rim, occasional errors make it unusually difficult to interpret.  Some are stamped backwards, and others might even have one or more digits upside-down.  Casseroles that are a bit newer have their model number clearly marked under the tab handle, while more modern ones are numbered on the bottom.

The most popular casserole size during this time span was 1½ Qt.  Aside from bean pots, every casserole shape could be obtained in this size, and some shapes, like square casseroles, were available only in 1½ Qt.  Among the many different shapes, round casseroles were the most popular, and they were offered in the widest range of sizes, from 8 oz to 3 Qt.
