Which Came First, The Trefoil or the Variant? - The Trefoil Collection (Pre & Post P-series)

I have posted about the Trefoil pattern before, but I think it's time to break the entire collection out. Not just the standard 1 3/4 quart & 2 1/2 quart Saucepans, Electromatic Skillet and the 3 percolators in the pattern that we are all most familiar with....

I mean the whole kit and kaboodle. 

Meaning the "Standard" Trefoil and all it's variants. (for there are 2)

Made available in 1960 to catch a "higher class" consumer, Trefoil hit the market smack dab in the middle of the Pre P-series era (1958-1961).  Thus, older pieces have the blurry blue ink print found on 2nd generation Corning Ware, which means they were paired with Fin handle lids,

while others are stamped with the standard P-series model # of the 3rd generation, meaning they deserve knob handle lids. (1 3/4 quart is the only "P-series" cookware piece I currently have)

The P-139 and P-136 Stove Top percolators (1963-1965) seem to have only been available in the "standard" pattern, but the Electromatic Percolator (P-13-EP) predates the Stove top models by 3 years. (being available in 1960 along with the Electromatic Skillet)  It is possible that it is available in the variant pattern.

Speaking of Electromatic Skillets, the Trefoil Electromatic Skillet predates the Cornflower model by 1 year.  Trefoil patterned Electromatics were available in 1960 while the Cornflower patterned version was not made available until 1961.  It seems that ALL three variants were available at some point in Electromatic Skillet form.  Since the Electromatic Immersible Warming Tray was not on the market until 1964, it is possible that a Trefoil pattern was never produced since the pattern was discontinued shortly after in 1965.

The "Scroll" variant (right), was only available on the Electromatic Skillet.  (Note: that though the booklet has the "Standard" pattern and the box states "Trefoil" the skillet that came out of it, is a "Scroll" pattern one)

The variant on the left, however, appears to have been around from the very beginning because of this piece...

The 10 inch Skillet with the Pyroceram lid.  (which isn't available in the "standard" pattern)

It has the "Blurry Blue Ink" dating it to 1960-1961, along with the odd sized 1 1/2 quart and a 1 quart size that have been found in this same variant.

That being said, it appears that the only cookware available in the "standard" pattern, was the 1 3/4 quart, 2 1/2 quart, 11 inch Electromatic Skillet and, of course, percolators.

In The Beginning - Corning Ware 1st Generation BPE (Before P# Era - 1958-1959)

So I have been photographing various chunks of my Corning Ware collection over the last couple of months.  This was for a 2 fold reason.   Firstly, I really didn't have anyplace that I could spread it all out and photograph everything all at once and second, well... there is only so much room for a photo on a blog post and I would have to stand back so far to get it all in that you probably would not be able to see much of anything except a bunch of little blue cornflower shaped dots.

Be that as it may, I decided that I was going about this the wrong way.  I should have been organizing my collection by Era and/or generations.  You see, there are several "Generations" of Corning Ware and those generations can be grouped together into Eras.  To make matters even more confusing, some of the patterns within generations can be broken down into "Editions"... Such as the Floral Bouquet pattern.  This is further complicated by the fact that there are separate "series" runs that occur for a short time within a generation that are retired, but then resurface again later...   So lets just start at the beginning...

In the first Era (AKA: Fin Lid Era), which encompasses 1958 - 1961, there were actually 2 generations of Corning Ware.... an embossed bottom generation and a blurry blue ink generation...   but today I am going to concentrate on Generation 1 (numero uno) from 1958 thru 1959.

In the beginning of the beginning there were no P, B, W, N, A, C, S, DC, F, G, U or L model numbers..   You see, Corning was unsure how well their cookware would be received by the American housewife, so they made a limited number of pieces for the initial release in the fall of 1958 to test the waters.....  These would be the 1 quart, 1 1/2 quart and 1 3/4 quart saucepan with fin lids (similar to the Pyrex FlameWare design) along with the 10 inch skillet topped with the infamous pyroceram lid adorn with more cornflowers.  With only 4 pieces, it was pretty easy to keep track of what was what, so no model numbers were really needed at this point. That does not mean that there WEREN'T model numbers.   They existed, but were only found on product order forms, not the dishes themselves.

Corning Ware was such a hot seller that, by Christmas, retailers were screaming for more.  So, in spring of 1959 Corning unveiled 2 additional skillets (9 inch and 7 inch with fin lids), a larger 2 1/2 quart Saucepan and the famed 8 cup & 6 cup pyroceram lipped percolators (which would later be referred to as P-108 and P-106).

All these pieces, percolators aside, have an embossed stamp on the bottom stating either "Corning Ware" with a volume measurement or, in the case of the skillets, width in inches. (7 inch skillet-top, 1 3/4 quart saucepan-bottom)

or simply "Corning Pyroceram" with no other identifying marks.  (bottom of 2 1/2 quart)

There ARE alpha-numeric characters embossed on the pieces as well, as is evident above with the A-19, D 16 and B-34, but these are by no means model numbers... they are glass mold numbers used for quality control purposes.  The model numbers we all know and love would not be applied to pieces until the second Era of Corning Ware in 1962 (3rd Generation) with the the P & W series followed shortly in 1964 by the B-series (and the C-series for Centura coordinated casseroles)

As mentioned before, they existed for ordering purposes, but were not present on dishes or lids.  While the dishes are the same as later, marked pieces, the official fin lid numbers are a little different.   There are only 2 lid sizes and the Pyroceram lid for the 10 inch skillet. 

The 7 inch fin lid is a P-11-C and fits the 1 quart, 1 1/2 quart and 1 3/4 quart saucepans as well as the 7 inch skillet.  The 9 inch fin lid is a P-2 1/2-C  and fits the 2 1/2 quart saucepan and 9 inch skillet.  The pyroceram lid is known as a P-10-C.  The later glass replacement lid was originally released as a P-10-C-1, but after the pyroceram lid was discontinued all together, the model number of the glass lid was changed to P-10-C.


So there you have it....   The 1st Generation of the 1st Era of Corning Ware.

3 from Pre-"P" - My Black Trefoil Collection

I suppose that it is only fitting that a pattern like Black Trefoil (3) actually came in 3 variations.   Trefoil is sort of a strange pattern though, as it was released in the "Pre" P-series era.  You see, originally (1958-spring 1961), Corningware didn't have model numbers.  During 1958-59 the information was embossed on the bottom center of the dish, but in 1960 Corning began using blue ink to print the dish size in quarts (or inches in the case of skillets) along with "Corning Ware Pyroceram" and "Made in the U.S.A".

Black Trefoil was originally released in 1960...  It's intention was to appeal to the "upper class" that might look down upon the humble little Blue Cornflower.   P-series model numbers weren't introduced until the Fall of 1961, along with the knob handled lids.  Thus, every piece of Black Trefoil produced before Fall 1961 had a Fin lid (like mine), and all pieces produced after (with P-series model number printed in black) had knob handles lids.

Now I am not sure which pattern variant came first or if they all came out at the same time, but the most well known is this one (shown on the 2 1/2 quart below)

which is known to exist in 1 3/4 quart (P-1 3/4-B) and 2 1/2 quart (P-2 1/2-B) Saucepans as well as the Electromatic Skillet (P-12-ES with an P-22-ES dish -- AKA: the SK-10) and several Percolators in both Stove Top (P-136 & P-139) and Electromatic (P-13-EP) versions.  (Please note that the 1st Generation Electromatic Percolators had different model numbers depending on the printed pattern.  The 10 cup Electromatic Percolator in Cornflower is P-23-EP while the Trefoil was P-13-EP.....   Also note that though the Back Trefoil Range Top models are identical in form to the P-116 and P-119, they were assigned different model numbers none the less.)

I have succeeded in getting my hands on the "Scroll" variant, but I have only seen this one on the Electromatic Skillet (SK-10) and not on ANY other sized piece.

Next to my "Standard" Trefoil 1 3/4 quart (cause it's printed in blue on the bottom) is my most recently acquired Black Trefoil variant...

Up until this piece, I had only seen the SK-10 skillet with this design... But even more surprising is the size of the piece.....

Yes, it really is a "1 1/2 quart" and not the more standard and well known 1 3/4 quart seen in the Main Pattern...   Thus, this one takes a Fin lid as well, like all the others.  Since this is the only piece I have seen, I cannot say as to whether the design carried over into the model number era beyond being applied to the Electromatic Skillet. 

I do not believe there is a Fin lid for the Electromatic Skillet as they were released in the fall of 1961, in the post Fin Handle Lid era...
