Glasbake Ovenware: What is it, who made it?

February 12, 2018
Glasbake ovenware was officially known as ovenware made of glass, and was a line of heat resistant oven/baking/serving ware developed in the early 1900s by the McKee Glass Company. It was originally known as Glasbak Ware. Note the missing ‘s’ and missing ‘e’. This is key to identifying when a piece was made, and by whom.

The McKee Company: Glasbake by McKee Division of Thatcher Glass Corp

The McKee Company was a long standing glass company out of the Pittsburgh region, and it was in the early days that it was spelled, Glasbak. In 1917 the spelling changed to Glasbake, and Ware was dropped from the name remaining this way through to 1953.

The company partnered with a number of  other firms throughout their history, which resulted in the spelling changes and subsequent company name changes. If you see Glasbake spelled with a double ‘S’ (Glassbake), this is not a McKee.

Here you see McKee’s telltale stamp and patent marking on the rim of an oven-to-table meat platter .

In 1951 ‘Glasbake’ was changed to ‘Glasbake by McKee Division of Thatcher Glass Corp’. The name then changed again in 1961 when Thatcher sold the McKee factory to Jeanette Glass. Jeanette Glass usually identified their Glasbake pieces with a number on the bottom that had a ‘J’ prefix. This is another tip for identifying the who and when of an authentic McKee piece.

What makes Glasbake so special?

What’s so special about Glasbake is their original marketing message, ‘From Oven to Refrigerator’. Glasbake pieces were designed to be used for cooking, serving and storing, and it’s this 3-in-1 combination that I think was so brilliant. Back when Sunday dinner meant pulling out all the stops, pieces like the meat platter certainly made cooking, serving, and clean up a seamless process.

Here is a full view of the Glasbake meat platter mentioned above. This magnificent piece circa 1927 was in Audrey Would’s Etsy boutique until just recently. It has since found its way to a new home, and is a great example of an oven to refrigerator piece.

Oven-to-Refrigerator: How this works

Imagine for a minute, serving a roast.

  1. Cooking

The glass platter was used to cook the roast, and the tree well pressed into the base of the platter was designed to collect the roast drippings. As you can see, the Glasbake platter sits perfectly in the silver stand, which made serving a breeze!

  1. Serving

The gorgeous silver plated serving stand was designed to glam up the platter, and the two combined made a deluxe serving statement. The stand adds a touch of elegance with its sleek lines and simple understated details, yet doesn’t feel too fussy to use.

  1. Storage

At the end of the meal all that’s left to do is cover the leftover roast right on the platter, remove the platter from the stand and store it in the refrigerator. Function from beginning to end, and a testament to great design.

Don’t you agree this is a well thought out design that covers all the bases for cooking, serving and storing a roast just right? If you have Glasbake in your collection, what pieces do you have, and which ones do you use the most? Please leave a comment. I would love to hear from you!

    Looking for a #2 lid for 1 qt oval yellow daisies – suggestions? Does pyrex fit?

    Hello – I happened upon a Glasbake J-235 1Qt Currier & Ives patten at a thrift shop that still has the label stuck inside the bowl. I am feeling lucky as it has obviously never been used, but then I wonder if I shouldn’t use it at all? Is it unusual to find dead stock like this of Glasbake? I wonder if perhaps it is not deadstock (aka new old stock) rather just something someone received as a gift that was never used. Sadly no lid.

    I have a Glasbake J-247 9″ x 9″ square blue cameo dish (baking or cake pan) Not the Grecia Urn pattern but the one with a single lady cameo. I cannot find any information on it anywhere. All I find are the round or rectangular pans. Does anyone know anything about the square one? Any information is appreciated! My email is

    I JUST found your site and I’m delighted! I have my mother’s Sunbeam mixer and one mixer bowl. The bottom marking is 19C J. Is this the Jeannette marking you’re referring to? It doesn’t seem to be it because the J is after the 19C. There is also a 3 over by itself to the left. Thank you, in advance, for your time!

    I’ve got a lidded loaf dish by Glasbake with the Westinghouse symbol on the fin handle of the lid. Poppy pattern. It’s so mint, I’m reticent to use it! 🙂

    • Reply Sheila Zeller August 1, 2020 at 4:38 pm

      Hi Ev,
      Thank you for your comment. If your dish is in mint condition I can completely understand your hesitation in using it, especially if you have it featured where it can be enjoyed. I am a believer in using my vintage, but I also take extra care when I do. I always hand-wash my pieces and clean with care. Either way, it’s wonderful that you have such a fantastic piece! I appreciate that you took the time to share! 🙂

    Hi: We have a Glasbak clear divided casserole baking dish j2352 that is my mother-in-law/s. The strange thing is that the handles and rim have a dark coating that is partially worn off. I was wondering if you know anything about that? I can send you a photo if that helps.

    • Reply Sheila Zeller August 1, 2020 at 4:33 pm

      Hi Jill,
      I’m intrigued but have to say I am not familiar with that coating. Perhaps a dealer who specializes in antique/vintage kitchenware might have specific information on that. I wish I could point you in the right direction… I do appreciate that you reached out. Thank you for that!

    I think they are pretty common, but I have a set of the Poppy Custard Cups and I love them. So simple and elegant. I use them for everything from portion-controlled snacks to hold beads for craft projects. The poppy design is simple and I love the art deco look of it.

    • Reply Sheila Zeller July 19, 2020 at 8:03 pm

      I love the Poppy Custard Cups – they’re so pretty. And how awesome in the way you put them to such great use both in the kitchen and for crafting. Thank you so much for sharing, and thank you for your comment! xo

    From the info you provide it seems to me that this might all be borosilicate glassware? or possibly even tempered borosilicate? or is it an early form of the tempered soda-lime???

    Thank you.

      Hi Raul,
      Thank you so much for stopping by and commenting on this piece. I wish I could confidently answer your questions, but I can’t. Hmmmm. Something more for me to look into! I appreciate your thoughts!

  • Reply Joan Swisher February 18, 2020 at 11:33 am

    Hello – I’m trying to identify a Glasbake pattern. The marking says “Glasbake J514. 2 quart”. There is also a small “18” between the marking box and the embossed bottom surface of the dish. The dish is milky white with a gold pattern that looks similar to the wheat patterns I’ve seen but looks more like a branch of leaves. Any help would be appreciated.

    Glasbake USA – looks like a single coffee container – glass in round bottom with rubber around the top? Can you tell me what it’s for? Thanks

      Iris, those were called “hottles”.

    I have a small (4-5″) shallow piece marked Glasbake 275. Is this a small bowl or a lid?

    • Reply Sheila Zeller November 10, 2019 at 4:41 pm

      Hi Peggy,
      Without seeing it I don’t really know because you will find markings on both. My guess is it’s a bowl but that’s honestly just a guess. You’re more than welcome to email a photo to me if you like.
      Thank you for reaching out!

    Wondering if this piece is really from the 1920’s

      Thank you for reaching out – do you have a photo of your piece? I’m definitely not an expert, but if you would like to email the photo to me I’d be happy to take a look.

    I’m picking up these dishes left and right a lot lately. Most are white with green flowers but, some are a brown glass with yellow flowers. They are all adorable and sitting with my Pyrex and Fire King. I can’t help myself when I see them at a thrift store.

    • Reply Sheila Zeller January 26, 2019 at 11:58 am

      That’s so great Lori! I totally get the “can’t help myself” challenge when at the thrifts. It’s so hard to walk away. I’m glad you give these guys a second chance!!

    I have a complete set of white with the green markings on it minus the meat platter made by the Jeannette glass company.

      Wow, Eric! That’s amazing – a full set is incredible. It makes me so happy to know there are complete sets still out there being enjoyed. 🙂

    I have a Glasbake 254 loaf pan with a poppy pattern on each side. Do you know if this glass contains lead and/or whether it is safe to bake with. Thanks for your assistance!

    • Reply Sheila Zeller November 9, 2018 at 7:50 am

      Hi Kathy,
      I don’t know for sure, but you can get a lead-testing kit in some hardware stores to test the pan for lead. If it’s lead-free then I would personally feel it’s safe to bake with.
      Thank you for checking in!

    Hi there, would love to identify the piece i picked at a flea market approx 4 to 5 years ago, this fish shaped dish is solid steel gold in color, extremely heavy and have marking on the bottom GlasBake USA 4141, the marking is kinda of up side down, i have googled and can only find glass dishes but none like this one.

    Would have been nice if I could attached pictures so as to see what i am talking about.

      Hi Vennie,
      This sounds like a really unusual dish! Please feel free to send a few photos to

    Just picked up my first Glasbake I’m keeping (I’ve sold others). A small oval green on white Grecian casserole – with lid! I was going to give it to an old friend who teaches Greek and Latin, but I can’t stop admiring it – so for now it’s mine. I really love Glasbake patterns – more than Pyrex – they are more colorful, more refined, more quirky!

    • Reply Sheila Zeller September 18, 2018 at 9:59 pm

      Thank you for sharing and describing your find! It sounds pretty amazing, and if you’re admiring it, I think it has your name on it! Enjoy!!

    Just found 2 white Glasbake for Sunbeam bowls at Goodwill, have a 1970’s avocado green stand mixer that was my Mom’s, the larger bowl broke a couple years ago and was half heartedly trying to find another clear glass one, saw the set of 2 white , they’re the same size and will fit the stand mixer. I don’t use the old mixer much but use the bowls all the time, great for mixing anything and storing cookie dough to bake next day.

    • Reply Sheila Zeller August 6, 2018 at 8:07 pm

      Thank you so much for describing your Glasbake pieces. I love the vision of the avocado green mixer, and even though you don’t use it much, what a great piece to have! I am so happy for you that you found replacement bowls – what are the odds? I think white sounds just right! I am so please you shared 🙂

    I have a divided casserole dish that I use to make “leftover casserole” on one side and vegetables on the other. It has a cute green floral design on the side and apparently had a lid that was also divided. Unfortunately, when I found it at a thrift store the lid was not included. Since the finish and paint are mint I would never put it through the dishwasher. I usually rub it with cold coconut oil before adding my other ingredients.

    • Reply Sheila Zeller June 9, 2018 at 8:28 am

      Denee, your casserole dish sounds amazing! Maybe one day the lid will come along, you never know what will pop up in a thrift 😉 I love the care you take with your dish, and love that you don’t put it in the dishwasher!!
