My love for old Corning Ware dishes

Note: This post is carrying over from my turkey soup post, in which a reader asked about freezing soup in Corning Ware.

If I ever wrote a second blog, it would be an ode to my favorite cookware, Corning Ware, and all the things I do with it. Can you freeze in it? Oh yes. Check this out:

This is a 1950s-era ad for Corning Ware showing half the dish embedded in an ice block, while the other side of the dish is heated with a torch. Old Corning Ware is TOUGH stuff — it’s made from Pyroceram, the same material NASA made rocket nose cones out of for the space program. It has incredible thermal durability. You can take it from freezer right to oven or stovetop without breaking it. In fact, I often thaw my soup stocks this way. I take the frozen dish out of the freezer, take its rubber lid off, and pop it right on the burner.

Note I said “old” Corning Ware — there’s a big difference between the 1957-1997 Corning Ware and the “new” stoneware Corning Ware of today.

In 1998, Corning sold its consumer products division off to World Kitchen, who began making “Corning Ware” out of stoneware. Stoneware is cheaper, and it does not have the thermal properties of Corning Ware made from Pyroceram.

If you buy brand-new Corning Ware at the store and it doesn’t seem kind of expensive, it’s likely stoneware Corning Ware and not Pyroceram. You can tell the difference by looking at the bottom of your dishes. If there are any rough, unglazed areas that are not shiny, smooth and white, it’s stoneware. Most of the newer stoneware pieces are also stamped with a warning NOT to put them on the stovetop, like this piece:

You really have to be careful, as in many cases the new stoneware versions are being made with the same (or very similar) molds as the old Pyroceram pieces. The stoneware WILL break on the stovetop, and it’s not designed for freezer use either.

Additionally, Corning Ware does still make brand-new Pyroceram pieces that you can buy. But they’re pricey –Amazon has several styles, a two dish two lid set and a single 3-quart dish with no lid.

If you’re local to Illinois, the Huntley Mall has a Corning Ware store, where you can pick up new Pyroceram pieces up — they do have good sales periodically. This store is also a great place to buy extra glass and rubber lids for your existing pieces. I use the rubber lids all the time for freezing food in my Corning Ware dishes.

My mom got me hooked on Corning Ware when I was a 20-something setting up my first house, and she has given me many new and secondhand pieces over the years. I just love them! (Can you tell?)

So, anyway, I do a lot of cooking and freezing in my Corning Ware — I like to make extra batches of whatever I’m making, freeze them, then reheat and serve right out of the same dish. I also have a wonderful Corning Ware Crock Pot, which holds a 3-quart dish. If I want to reheat something slowly versus heating it on the stovetop or in the oven, I’ll drop the dish in here with a glass lid and let it heat all day:

This style of Crock Pot was made somewhere around 1993. (Wish they still made them!) You can find them on Ebay, but I’ve seen them sell upwards of $40-$60 used. (Then again, Crock Pots last pretty much forever.)

I’ll leave you with a couple of my favorite Corning Ware ads too. These, and the “ice and fire” photo above, all came from the fantastic Complete Guide to Corning Ware & Visions Cookware book, which is now out of print. A good substitute would be this guide to Corning Pyroceram Cookware, both of which have great guides to pieces and patterns, plus some amazing vintage ads:

“It won’t break or warp from heat or cold — even if you’ve just taken it off the burner and put it in the freezer. Slip the cover on it and it’s a storage dish. Put it in the freezer and it’s a freezer dish. Pop it in the oven and it’s ovenware.”

“You can take it from freezer cold to range top heat without fear of it breaking or warping.” And oh, the part about “The more you have, the more you want?” Just Photoshop my head on that lady in the pink housecoat and let me find all of these pieces under the Christmas tree..!


  1. J.R. says

    I too lament that “it’s not what it used to be”. I miss the original blue cornflower. Their glass beakers also are inferior to the old stuff.

    And the Huntley outlet prices just aren’t that great any more either. I think something management / owner wise changed there several years ago and the good deals vanished.

  2. Turken says

    Hey Jill!

    I’m another CorningWare aficionado here, and wanted to throw out a few tidbits that I thought you and your readers may find interesting:

    First off, for those looking to acquire corningware, a great place to look is estate sales. The stuff literally lasts for generations, and so if your grandmother didn’t pass along any pyroceram to you, then you might luck out and get someone else’s grandmother’s set for cheap. In fact, from what I understand, the extreme durability is part of the reason Corning stopped making it for some time — by the late 80’s pretty much everyone had a set, and the dishes people owned just weren’t breaking often enough to sustain a market for replacement pieces. My personal prize piece of corningware is one where the pyroceram label is actually *molded* into the bottom of the dish, and the lid is also made of pyroceram. From doing a little research at the library, I came to find that this one was likely manufactured back in the mid ’50 in the first year or two that the product was made.

    On the science side, pyroceram is a material known as a glass-ceramic. This means the dishes are created from molten glass, pressed into a mold to shape, and then after cooling somewhat are reheated to a temperature at which the glass micro-structure converts into a crystalline micro-structure. The smooth surface all over comes from the glass processing step, and the remarkable toughness comes from the crystalline component. Pyroceram’s unique thermal properties come from the fact that the micro-crystals react to heat by expanding in two dimensions while contracting in the third dimension. So, in a dish comprised of billions of randomly oriented crystals, the net change in length in any direction (i.e. the thermal coefficient of expansion) over the temperature range found in typical household use is almost zero. No change in length means no thermal stress and no shattered dish when you place a frozen pan on a hot range top.

    Anyway, I could go on at length about the stuff (my master’s thesis involved creating a catalytic material starting from the same “recipe” as CorningWare) but don’t want to bore you too much. Just want to say you’re not crazy for loving the dishes (and for despising World Kitchens… but that’s a rant for another day) and that if anyone out there has some corningware, cherish it! It really is a great material!

    • says

      Not boring at all – I am as fascinated by Corning Ware as you are (and my apologies for the late response to this post too. I am so backlogged in responding to comments!) Is your thesis posted anywhere?

      I second the estate sales/Goodwill store route if you don’t want to break the bank putting sets together. Corning Ware is incredibly tough, durable stuff, and I really do use mine daily! :)

    • Erica says

      Yes I’ve acquired most of my collection of Blueflower from yard sales, rummage sales, or estate sales. And it shocks me when you ask what they want for the piece and they say $1.00!!!! Has become a big habit but it’s worth it. Something I can pass down to my daughter just as my mom has done.

  3. Susiem68 says

    Corning ware jumped on the new no plastic bandwagon? I grew up with this stuff but had no idea you could cook in it on the stove. I thought it was just good for baking! Now I will be looking for some! But anyway…with so many people going away from plastic containers and buying glass you would think someone bright at Corning Ware would jazz this stuff up and push it as Eco friendly and BPA free. There is a whole generation I think that will think this is cool to cook serve and store in the same container. Less energy used. Less wasted time and less wasted water.

    • says

      No kidding – I hadn’t considered that it really is a “greener” choice! It’s safer than putting food in plastics, and I have always loved the convenience and ease of cooking, serving, storing and freezing in the same container.

  4. Supermom10 says

    I love my Corning ware! Thanks to my husband, he had a bunch from before we were married. I have had not much luck with lids – I have broken a few – slipped out of my hand or falling from a cabinet :( I have found some pieces at Goodwill & Salvation Army – so if you are looking for any check those places also.

  5. Coupon Maven says

    I went to the Corning Ware store tonight in Huntley (11800 Factory Shops Blvd, Huntley, IL) to get a few more plastic lids for my pieces (soup-making day revealed that I had a few more pieces without the freezable lids.)

    All of their open stock pieces (single pans, glass lids and plastic lids) are Buy 2 Get 1 Free through 12/26. All Pyroceram Corning Ware boxed sets are Buy 2, Get Both 40% off.

    If you want a better deal, buy something small – after I bought my lids, my receipt printed a $10-off-$40 good 12/11-1/10/14, and a $5-off-$20 coupon on the receipt if I fill out a web survey about the store. I imagine these would print with any purchase…

    Anyway, if you’d like to see what they have in stock now, here are some photos I took:

    These pans are all $32.99 each, Buy 2 Get 1 Free.

    The larger pans are $59.99 each, and the glass lids range in price from $4.99-$8.99, all Buy 2 Get 1 Free.

    The smaller pans are $27.99, and the larger pans are $32.99, Buy 2 Get 1 Free.

    4-piece sets (2 liter, 3 liter dishes and lids) are $99.99 and 40% off when you buy two boxed sets.

    3-piece Petite Pan sets (small pan, glass lid, plastic lid) are $34.99, and 2-piece 1.5 liter dish sets are $29.99 – also all Buy 2 Get 40% off. This is not a good deal for the Petite Pans — they are very tiny pans, about 4″ square.

    Surprisingly, the larger 1.5 with the lid is cheaper than buying the lid and pan separately. If anyone’s interested in buying new, these sets will be $18 each if you buy two, which is a pretty “good” price for new Pyroceram Corning Ware. Add in the $10-off-$40 coupon and/or $5-off-$20 and these will be even better.

    As Turken wrote below, the new Pyroceram pieces all have “Made in France” molded on the underside.

  6. Kathy Crismore says

    i have a question, I recently bought a casserole dish at a thrift store with the blue corn flower design on it but It has no brand stamp anywhere . Did Corningware always stamp there pieces? I am thinking this is a fake piece.
    Thanks for your help, Kathy

    • says

      Almost always, but lack of a stamp doesn’t mean it’s not real Corning. If there is no stamp, sometimes you can see a physical impression of “CORNING” or “CORNING WARE” on the bottom of the dish in the glass itself. Even if there is no stamp at all, if you have other pieces to compare it to sizewise, etc, you can usually make a determination.

      Is the glass fully opaque white or is it “milky?” Anchor Hocking also made pieces in the 60s-70s with a very similar knock-off blue cornflower pattern. Corning Ware’s glass is very bright white with no translucency.

      I took a photo for you with one of my genuine Corning Ware pieces and a knockoff Anchor Hocking for comparison:

  7. Judy Miller says

    i own a piece of vintage cornflower corningware unlike any I have ever seen. It has a lid of the same material as the “pan” complete wth blue cornflower design, not a clear glass lid. The only markings are on the bottom- Corning PYROCERAM T.M. A27. Any info on this piece would be appreciated

  8. CJ says

    Can you give me any tips on prepping the dishes before you use them? For instance, do you butter the dish or wipe with olive oil? What about making pies in the pie plate – any special prep (butter / flour the pan)? I have a square dish I’d like to try a casserole in and also a pie plate I’d like to try making a pie in, but I want to be sure I prep/care for everything properly.
    Thanks for any input you can provide!

    • says

      I don’t do any special prep, really — I just bake right in the pans. I definitely don’t do anything special when I make pies. I suppose you could butter it, but I never have. :)

  9. Dawn R. says

    I appreciate this post so much! I inherited the blue cornflower set from my grandmother. They are certainly older than me and still look like new (with the exception of some one chipped lid and one missing dish that was broken and caused me to get stitches). I had absolutely no idea that they could go in the freezer or on the stove, purposely! And it’s Thanksgiving. This changes everything.

    • says

      You’re welcome! Yes, Corning Ware truly is incredible, timeless stuff. I have several pans that date back to the 1950s according to the stamps/markings on the bottom, so they’re much older than I am too.

      OUCH on the stitches. As tough as Corning Ware is, it’s not completely unbreakable. The edges on the shards are VERY sharp if you do manage to break it. My daughter dropped a piece while standing on a chair and reaching for it from a high cabinet — that one did break into some seriously sharp pieces.

      Have fun with your new freezer/stovetop discovery — it DOES change everything. :D Think about making soup stock after your turkey’s been picked clean, then freezing the stock in Corning Ware — you can just heat it right up from frozen on the stovetop, then put noodles, vegetables in for soup. I freeze my chicken and turkey broths a little above halfway in the 3-quarts to leave room for soup ingredients. (I have that Corning Ware Crock Pot too that the dishes fit into, which is also great if I’m not in a hurry to thaw things out.)

      Happy Thanksgiving!

  10. WestieMom says

    I ordered the Corningware Pyroceram Blue Cornflower 4 pc. Casserole Set from the company that took over the Corning Ware line. I noticed that the underside of the 3 L casserole dish had a weird texture. Hard to articulate, but imagine a patch of clear, skid-free material heat seared onto the underside. I thought maybe it was something new that was added to help prevent scratching the underside? But the 2 L casserole had a smooth underside, so I’m guessing the 3 L slipped by quality control. I am hesitant to use the 3 L as I don’t know how it will react to being on a gas burner. Or in the oven, for that matter. I will be contacting their customer service regarding this, but I was lucky enough to find your site and wanted your feedback first. Thank you!

    • says

      WestieMom, I can’t say that I’ve seen anything like that before! My newest pieces of Pyroceram CorningWare are from the Martha Stewart for Kmart line from 2004 — Corning had reissued the original Pyroceram material for a few pieces branded with Martha’s name. Those pieces are identical in composition to my vintage pieces.

      I have seen the new Pyroceram Corning at the CorningWare store near my home though, and I’ve never seen anything like what you’re describing. If you want to email me a photo, I’ll post it —

      • says

        Here are WestieMom’s photos of the textured bottom surface of her 3 Liter new Corning Stovetop dish:

        I really haven’t seen anything like this before, but as you said, it doesn’t look like the surface is unintentional (though why does the smaller piece have the traditional smooth-surface bottom then?)

        If anyone else has seen this kind of surface on a NEW piece of Corning Pyroceram, please feel free to chime in. And, WestieMom, do share what Corning/World Kitchen says if you get response from them. I’m curious too.

  11. Terry B says

    Hi, Glad to find more Corning Ware lovers! I have a question that I haven’t been able to find an answer to so I thought I’d mention it here. I inherited from my mom two exact 1 quart (A-1-B) dishes with lids. The pattern is the same on both: L’Echalote with tomato centered along with other vegetables. The only difference between the two is a light yellow-colored underlined number after the word “L’Echalote” on the design. On one dish the number is 22 and on the second dish the number is 30. I have looked at lots of photos of this design and none of them show a number like these two do. Does anyone know what these mean and why it is not on all of this design? Thanks for your help.

    • Michele says

      The A-1-B is on all the vintage Corning Ware dishes, sometimes stamped with dark ink and other times – what’s the word? Engraved or imprinted (to where you would not be able to see that in most photographs).

  12. Juanita says

    Is it safe to use on glass top stoves? I read not to use metal utincials on them but the plastic that I used this morning left little black marks on it. Can you advice?

  13. frances says

    I have a lot of the cornflower pattern…mine have stamps on the bottom..but some are black and some are blue…does anyone know why they are differ colors?

  14. Marilyn Adams says

    Can we assume that the Corningware we grew up with in the 50s and 60s and 70s can all be used on the stovetop (both gas and electric….flat top electric too) and the microwave? And where do I find a guide to what the numbers and letters on the bottoms all mean? I’m just re- discovering the wonderful world of Corningware!!! I am now looking at all my pieces with renewed respect!!!!! Thanks!

  15. Marilyn Adams says

    Ok….you are a dangerous woman! You got me hooked on Corningware again. My grand daughters are already rolling their eyes at me when I mention yard sales to them! Ha!

    I just scored a P-12-ES electromatic skillet!!! Now my question…..can I use ANY Corningware piece on it? I’m still trying to learn (or at least get a handle on) all the numbers and letter designations for the various pieces. I have noticed that some pieces have a flatter bottom than others. Were they designed that way for use on the Electromatic? Do some of the dishes work better than others on it?

    Working on learning curve here now! I wish my mother-in-law was still with us. She’d be all over this!!!!!!

    Thanks again!


  16. Carolyn Parrish says

    Recently (March 2016) I broke a glass lid from one of our old Corning Ware 5qt dishes. I ordered a new one from Corning Ware (World Kitchens). When it came, I put it in the dishwasher with some other dishes that included Coring Ware lids. When the load was done, the new lid was in a thousand pieces. I was told to send it to their Quality Control for testing. I sent it in along with the repair bill for the dishwasher. Their response was that the lid was made before 1972 and that we had scratched it to cause the breakage. Could that be true, that it was made before 1972 and they were just selling it now? In other words, they are saying that it was one of our old lids and we were trying to get a new one and have our dishwasher fixed for free.
    My question is this “Is there a way to know when the lid was made”?

    • says

      World Kitchens bought the Corning name and brand in 1998. If you bought any lid from them, I would think it is far newer than 1972..! It sounds like they are attempting to say that the lid that broke was one of your own ones, which I think is very unlikely.

      Pyrex has always made the glass lids for CorningWare products – very few had actual lids made of the white Corning Ware pyroceram material, though some did.

      Old Corningware pieces came with Pyrex lids made of borosilicate glass (you can Google the properties of it – it’s strong and very heat resistant.)

      The “new” Pyrex products (post-1990) including the lids made for Corning Ware, are made of soda lime glass, which is cheaper to manufacture but is more prone to the kind of breakage you described — shattering into many tiny pieces. Borosilicate glass usually breaks into large shards. Judging simply from the way it broke, I’m highly inclined to believe that it’s a newer soda lime glass. The combination of a rapid temperature change and moisture can cause it to shatter — and if it was put in the dishwasher hot, it’s likely that’s how it happened.

      More reading:

      I have bought a couple glass lids at the Corning Ware store at the Huntley mall over the years, and the new lids are soda lime glass. If you look for a “new” lid or any new-to-you Pyrex pieces, I think it’s better to look at thrift stores. The old (better) borosilicate glass is crystal clear, where the newer soda lime glass has a little greenish tint (very slight) around the edges of the piece — that’s how you can tell them apart. I got my newer lids cheap enough that I didn’t worry about it too much, but the old stuff is definitely better made.

  17. says

    Great post. I will have to share this with my mom. I had no idea about the science behind Pyro ceram. I personally have 2. 1 cornflower and one with a vegetable design. I love them both so much. I am always on the hunt for more.

  18. Lisa Aceti says

    I used for work for Corning in Canada…and just recently found my blue cornflower Pyroceram collection!! I had it on display in my office as a nostalgic kick when customers and sales folks would pop in. I don’t want to hang onto it any longer. I have approx 25 pieces, plus lids in my collection….AND AM WILLING TO SELL IT All. Since there are alot of Pyroceram lovers here…I’ll post it to you first! Please contact me at or 905 650 3445 and I’ll send you photos.

  19. Jodi Schwarzl says

    I found an old cornflower pamphlet in a packet of recipes that my great aunt gave me 20 years ago. I looked online and can’t find something that looks exactly like it so I don’t know the age.

  20. Calibabydolly says

    Hey Jill- I found a 10 inch microwave browning dish made for Sears at a garage sale last weekend. For a dollar! I own no other pieces but was raised in the 70s by a mother that cooked ONLY in Corning. She was the 1st one on the block with a Corning flat top range and an Amana microwave. She took a class at the library to learn how to master it, sadly, she did NOT! I just searched online to find out about this piece. I was thinking of making turkey bacon in the microwave in it but today I made a butternut squash in it. I basically love Corning AND Corelle because it does not get hot in the microwave. I have a huge set of Pfaltzgraff dishes (bought a whole box of new condition matching pieces at same garage sale for a buck!) but they say they are microwave /oven safe but they are not good! They are stoneware, period. I also found a small Pyrex dish for 25c at the sale. Anyway, I wondered if you own any of the old browning dishes? This is the MW-16. (It’s the one with the feet on the bottom)

  21. Cindy Kue says

    Hi! I have a blue cornflower dish with nothing on the bottom, but it is shiny- any clue if it is old or not? Opaque and not milky

    • says

      Sounds like vintage Corning Ware to me! The only way to really tell the age of something is to look at the shape of the sides. I don’t have my Corning Ware books in front of me at the moment, but the very old Corning (1950s-60s, if I remember correctly) has sides that are slightly tapered toward the bottom of the pan vs. the straighter sides of the Corning Ware made in the 70s until present.

      If you look at this photo, the blue cornflower pan on the right side of the stove is an old one — the sides are more angled than the newer pieces.

      (Keeping in mind that my “newer” pieces on the left are from the 1990s..!)

  22. Rica says

    About 10 yrs ago an added surprise wedding presents i received (fr MIL) are sets of Corning Ware Pyrex Vision and the like are all the new versions. The “Corning Pyroceram Cookware’ for sure are just the “new ones” of course never “vintage” Since I’ve been using it (stove top-oven-table-freezer) so far i’m lucky nothing disastrous yet has happen though i read Pyrex shatters. My question for the cookware C Pyroceram is HOW WHEN WHAT ‘proper care’ should i do to lengthen the life of it?

    • says

      Pyroceram Corning Ware is TOUGH stuff. Aside from dropping it onto a very hard surface (ceramic floor, granite counter) it will likely not break.

      Visions is a little different. I have no personal experience with it, though I too have read that it can shatter — I believe that was largely the reason it was taken off the market.

      I use my Pyroceram Corning Ware daily — I freeze in it, use it on the stovetop, and I use it in the oven and microwave too. I have never had a piece break or shatter while being used for cooking. I can only recall two of my pieces breaking, ever — once, my husband dropped a 1-quart filled with frozen soup on the concrete basement floor. My daughter also dropped an empty loaf pan from a height of about 7′ when she took it off the top shelf of a cabinet.

  23. soapboxtray says

    Hi Jill! I have been busy, my husband and I got licensed to be foster parents (we have 5 kids between us so what are a few more?), and so we had our first placement January 7th of this year, 2 toddlers, 1 1/2 and 2 1/2. We moved them into an awesome foster home with their 2 younger siblings (6 mo. old twins) and said goodbye to them Aug. 6th, this past summer. We know it is best for them all to grow up together but wow was that hard. It has been a process, lots of ups and downs but I wanted to drop you a note and tell you that today, finally, I used my crock pot that I bought on ebay a few years back. I had also searched Goodwills and Salvation Army’s for the Corning Ware. I have 4, 3 qts. and lids and the plastic freezer lids. September I finally filled them with 2 batches of chili and 2 batches of pot pie filling. I cooked in the crock pot for the first time and put right from the freezer into the crock and came home to lovely chili. Seriously why are these crock pots off the market? This is on my list of greatest inventions ever. 1. Heated mattress pad, 2. Soda stream (gave up soda 2 years ago but just found out you can make it without any flavoring in a soda stream just seltzer water, yes under a rock), and now this setup! I just wanted to say thanks for this article!

    • says

      Congratulations on your new roles as foster parents! I can only imagine how hard it was to see your foster children go after having them for so many months.

      The Corning Ware Crock Pot is THE most amazing thing. I agree that it is indeed one of the greatest inventions ever! Let’s all just look at it again:

      I honestly don’t know how many 3-quarts I have now, but I bet I’m up to 10 or 11. I use that “freezer to Crock Pot” move at least once a week — I always have soups and chilis frozen in them and ready to pop in the pot. The interchangeable dishes is what makes this setup so great, because you can freeze ahead in multiple dishes.

      Anytime I make a whole chicken or turkey, I will freeze the stock & leftover shredded meat in a 3-quart Corning too, leaving enough room to pop some vegetables and noodles in there once it thaws.

      Confession time: I have TWO of these Crock Pots now too. One is in perfect condition (my main one) and the other was a Goodwill find with chipped paint. I have considered repainting it with high-heat paint, but it’s my backup! I actually got it so my daughter could have one too. It works fine, but cosmetically, it’s not great.

      Did you know that you can put the same dimension Cornings in the pot that are the shallow depth (same square shape, like 1 1/2 quarts, but they are half the height? See the ones on the left side of the above photo.) That pot will heat them just fine as they heat from the walls, not the bottom. If I have small batches of food left (sloppy joe is great in these too) I will freeze in those half-height dishes and pop them in the Crock Pot too.

      The topic of the amazing Corning Ware Crock Pot MAY be deserving of its own post. :)

  24. soapboxtray says

    I agree it is deserving of its own! :-) I would be a follower for sure. I did have a 1 1/2 qt. but it broke :-( we opened up the drawer that I keep them in and it was unbalanced with a few of my 3 qts and those fell on top of it, thankfully it was just that one that broke, but I didn’t know that I could use that size, I thought maybe it wouldn’t heat it, I will have to search for some more because I can already tell that my 4 are not enough when I make a big batch of chili or soup. Great idea to put the stock and chicken in there I have become quite fond of making chicken soup with stock anytime I have a whole chicken, and can’t believe how easy it is really!

    You would probably laugh at my crock pot, it was for sure used and used well when I bought it but it works perfectly. I actually think the chili tasted better frozen and cooked in the crock all day, the beans were softer and the seasoning better. YUM!

    Hello, We have a large amount of older design corning ware and are interested in selling it. All in excellent condition. Must be seen to appreciate. if you are interested, contact us as follows.

    Hi, I have one of the old lids with the wing handle. Pyrex is stamped under neath the outer rim of the lid. There is a very small, deep, hand etching on the top part of the lid. Engraved “PD 1536A”. Has any ever seen this on a lid. I’m thinking it might be an early product prototype. I grew up with Blue Corn Flower, never knew you could take from freezer to stove top. I have recently started collecting. Today I found a smaller dish, pyrocam, with darker corn flowers on it, it looked almost navy. Just discovered your blog today, so excited to follow it.

  27. Penny says

    Avid Corning Ware user. I have a cupboard full mostly white with a few designed and French Whit ribbed too. Love the small baking /freezer dishes. I scour thrift stores and auctions. I had the crock pot and put it out for garage sale. It didn’t sell . Luckly… Because after reading your blog I wondered why in the heck would I have put it put there in the 1st place. lol A while back I found an original white cooktop! YAAAAY! :-) I have an electric coffee pot but it is very heavy so I don’t use it much. I think some would agree that once you start collecting it it becomes an addiction. But it’s a healthy one…. :-)

    I have a 1959 Blue Cornflower square pan like a frying pan with the original Pyroceram lid which now has 2 minor chips. At my bridal shower I was given the 3 piece set that included 2 smaller saucepans and an interchangeable handle that snapped on and off all 3. I eventually gave the small ones and the handle to my mother. The set was supposed to be used on the stovetop as well as in the oven but I was never happy with the stovetop results. They came straight from the Corning factory in upstate NY–a friend’s father worked there. The lid isn’t marked but the embossed bottom of the pan says “Corning Pyroceram TM Made in USA B-14”. It’s still in constant use almost 60 years later.
