P315 B  a 4.5  X 11 inch loaf pan

Pros: long-lasting, beautiful, durable, nonstaining,

Cons: used since the 1960s, not a con in the world for me

Corning Ware® original Pyroceram® cookware P315 B is a 4.5 X 11 inch loaf pan suitable for storing prepared dough and baking loaves of bread, storing a prepared meatloaf and baking the meat loaf in the oven and serving from the pan on the supper table. The pan is dandy for preparing lasagna or whatever entrée you choose to prepare ahead and bake later, or prepare now and bake now and serve for supper tonight.

These pans are meant for use in ovens and microwaves in addition to being used for storage in freezer and refrigerator. I have used my loaf pan in standard electric oven, not toaster oven, at heat to 350 – 375° F.   I stored many meat loaves and bread loaves for baking later in standard upright and chest type freezer and in refrigerator. These pans are not intended for stove top, burner, usage.

I have purchased, used and enjoyed Corning Ware original Pyroceram cookware from the time I first saw the initial advertisement for the product on television as a teen babysitting for spending money.

The concept was intriguing, the product was beautiful, and the notion that cook and serve in the same pan was possible, nicely,  had great appeal.

I date myself; my initial purchase went into my –hope chest– to be used when I was either married, or had moved out on my own following college.

Today, I still have, and regularly use,  my very first loaf pan and several others as well. There is nothing quite so tasty as good homemade bread, with butter and jam we made ourselves.

My Corning Ware Cornflower Loaf Pan features those pretty cornflower blossoms as was found on all the first pieces of the product. This 2 quart pan is a perfect size for making bread for supper, there was enough for everyone, but not so much that we had stale bread later. The pan was a dandy size for baking meat loaf, and because I had more than one pan, we enjoyed fresh bread AND meat loaf often as my boys were growing up.

My favorite bread recipe makes several loaves. I found having a group of loaf pans enabled me to divide the recipe into four portions, 1 for baking and 3 for freezing to take out later, let rise, and bake another day as well as having a dish for baking the entrée if.

This attractive pan ornamented with stylized blossoms, leaves and stems enjoyed a long manufactured run beginning in 1957 and continuing until discontinued in 1988. The pan includes a poly lid for use in freezer. Snap the lid onto the pan, and if you have several pans stack in freezer.

The top edge of the pan is smooth, has tabs at either end, and along the longer side is  a lip.


The lid is made with a lip to fit over the tabs at either end of the rectangular pan, and has a depression at the top surface allowing the bottom of the pan to seat down into the depression creating a nice, sturdy stack of pans filled with bread dough, meat loaf, chicken and dumplings or whatever you choose make ahead and freeze. Stacking the pans allows greater use of freezer space.

The poly lid should not be used during baking, broiling or top of the stove cooking. I do not use the poly lid in the microwave. I want the lid to continue to fit snugly in the freezer; microwave may cause the lid to warp.

My own personal cooking habits have long been to prepare several meals ahead; I found during the years I was raising children, having several meals in the freezer for popping into the oven made preparing supper a good bit easier and smoother for a busy household where both parents worked and children were active in scouting and we all attended church each week.

Pyroceram, a glass ceramic material initially developed for usage in the infant ballistic missile program the United States was realized as a possibility for crafting cookware capable for going from hot to cold or cold to hot without problem. The pans are nice enough to use for serving on the table, can be used to cook or warm foods in the oven, on the stove top and under the broiler.

I always liked having fewer dishes or pans to clean up after the meal. As more women began entering the work force as did I, the idea of prepare foods on the weekend, freeze, cook as needed and serve in the same pretty pan removed from the freezer held a lot of allure for myself and many others of my generation.

Nearly indestructible, easy to clean, difficult to burn food in the pan, Corning Ware’s record for durability was one of the things which ultimately led to problems for the company. No need to replace items that just don’t wear out, stain and become less attractive and the like.

My appealing, vintage, loaf baking pan(s) have been used many times during the many decades I have had the original, and all the others I have added to group. The original pan, as well as the ones that followed, continues to have a fine, unsoiled, lustrous white inner sidewall notwithstanding being used for myriad meat loaves replete with the tomato sauce we enjoy,  as well as other entrees in addition to loaf type cakes, loaves of bread and whatever else I have stored, baked and stored again whenever there were left over portions.

Over the years I added a number of other pieces to my initial corn flower blue casserole, loaf pan etc.

Initially each piece has also featured the pretty blue cornflower. I liked the fact that the pieces I bought during the early 1960s all matched, never wore out and short of deliberately throwing them onto a cement did not break.

Now that it is just Husband and myself I have kept the smaller pieces, and have given away most of the larger ones to sons as they have begun their own families.

And I have begun collecting one or two of the many other patterns produced during the hey day, as I find them in local thrift, jumble shops and garage sale offerings.

I always liked the appearance of the newer patterns, but as many other women, just could not justify replacing what I had.  The pans were beautiful, didn’t stain or break or anything untoward.

We were a generation not prone to replace just to replace, so I have kept, and now I add a smaller pan or two and this past weekend, another loaf pan!

If the price is good, it is hard to pass it by as I wander the aisle of the jumble shop.

I did buy some of the newer stoneware type baking dishes, and other than the mugs meant to be used in the microwave have given those pieces away. I find they are not so durable, easy to clean and keep clean and serviceable as are the original formula Pyroceram pieces.

NOTE: The following is information regarding Corning Ware/World Kitchen LLC.

If you, as I, am/are a collector, or think you might like to be, and/or have an interest in company information or perhaps need specific information regarding the manufacturing company itself, types of products made, where Pyroceram Glass items were mass-produced including years of issue, as well as, where they may be offered for sale today as well as other pertinent information regarding these lovely, serviceable pieces; you will be pleased to read, books are beginning to be written regarding the patterns, pieces, and company itself.

In addition, I am beginning to see a number of online sites offering pieces for sale. My own preference is for the pieces often found on shelves of local jumble shops, in thrift shops, as inventory during estate and garage sales and the like.

If bought from sites online;  the cost will be substantially more.

Original formula Pyroceram was discontinued during the late 1990s, and the new stoneware was introduced. Pieces are not manufactured as replicas, but the stoneware is not original formula Pyroceram. From internet search including perusal of the Corning Ware webpage: we learn that as happens with many new creations, Corning Ware cookware came to be because of a lab mistake.  The furnace failed, temperatures supposed to remain at 600C rose to 900c. However the glass did not become molten, retained its shape, and did not break when the startled scientist dropped the white glass produced.

This product that so many of us continue to use in our kitchens originated in 1953 when Pyroceram, a white, pyrex, ceramic like material having ability to tolerate vast disparity in temperature, was developed by Dr. S. Donald Stookey of Corning research and development division.

Primarily developed for the U.S. space program; Pyroceram was created from a substance originally meant for a U.S. ballistic missile program.

Dr. Stookey’s research centered around heat resistant material for nose cones. The original TV ads showed a rocket in the air, discussed the nosecone and showed a beautiful white with cornflower blue blossoms; cook pan. That is when my love affair Corning Ware™ original Pyroceram® cookware.
