- Corning Blue Corn Flower Casserole, lead free! (non-detect for lead).
- Tested with an XRF
- Year of manufacture unknown
Many of the ones like this (with this blue pattern) that I have tested have been negative for lead, but not all of them and it seems to depend on the year of manufacture. HOWEVER any of the similar pans with the multi-colored decorations have been positive for HIGH LEVELS of lead!

If you appreciate what I do (XRF testing of consumer goods and sharing the results here and on Twitter and Facebook!), the simplest way you can help support my advocacy work at NO EXTRA COST to you is to click on the Amazon affiliate links in the post or Amazon ads to the right on this page (or on the bottom if you are on your phone!). If you click on any of the links before you start your Amazon shopping as you normally would, then Amazon sends me a percentage of whatever you spend – and you don’t even have to buy the items pictured! š
Also – when we reach $5,000 on my GoFundMe, Carissa and I are going to do another round of #GuerrillaXRFTesting at a store chosen by our followers (like the #GuerrillaXRFTesting we did at Target back in February!)
Happy shopping! & Thank you for your support! – Tamara
Will you please tell me if any of the Corning casserole pans had arsenic or other metals? I read your list that they are lead free but what about the other metals? Thank you so much.
Yes, I would love to know as well. I have a coffee carafe that is blue cornflower and I wondered if perhaps you have tested one of those in addition ;o)
Hi Tamara, you state the year of the blue cornflower dish you tested as āunknownā. I am just wondering if there is any clue you can give us to an estimated span, ie: was the dish you tested, one youāve had a long time, or did you buy it recently? Was it the older kind that can go from oven/stovetop to fridge etc? Those things could give us a clue to estimated production because my clue cornflower Corningware has been in my family for years and is still in good shape, but I know they made a new type, not coated with Pyroceram. Iām just wondering if you know which type you tested because there are some available at my local thrift store in good shape as well. I would love to still have the stove top to oven option. Thank you for any help you may give.
Hi Jenni,
I donāt generally test and report on things I own (thatās rare – we own almost nothing!) I test and report on things other people own and I report what information they have available to me at the time that I report the results – so I simply donāt have access to this information.
Tamara
The best bet would be for someone to send me one to test where they are certain of the year purchased new / year of manufacture and then I could report on that. Hereās how to send me an item: https://tamararubin.com/2019/08/tamara-can-i-send-you-one-of-my-dishes-to-test-for-lead/

Ok, thank you for your quick reply. I may try to send my most used dish so that if there is any lead present, it will be the most likely to show up on a test. Iām going to see if either of my sisters know an approximate year Mom bought these dishes, but Iām guessing it would be 70ās.
Any idea about the blue cornflower coffee carafe or if the blue cornflower pans have cadmium, arsenic, or mercury?
Pyrex color cookware from 1980s..
was the blue cornflower corningware you tested vintage or something produced in the last 5-10 years? thank you!
Sorry, I have no way of knowing. It’s most likely that the older ones are leaded and the newer ones are lower lead or lead free, but these do not have a year of manufacture marked on them (that I am aware of.)
thank you so much tamara! the newer ones produced under Pyrex brand, but also blue cornflower design have no model number and capacity stamp on them. the vintage ones have model numbers and quart/liter stamps that collectors look for. so i guess the blue cornflower corningware you tested was new-ish – post 80’s ..
The flared sides of the casserole and the small handles indicate it was an older Cornflower Corning Ware casserole. Going forward they made the sides straighter and the handles bigger.
Thank you for commenting Yvonne!
I will keep a lookout for those distinctive characteristics to see how they relate to lead content!
Tamara
Tamara, am I reading your posts right that the white pyroceram surface is lead-free, but the decorative decals on the outside are the problem?
Yes – that is correct.
Tamara, we eat every day on Corning Ware vintage blue cornflower plates ? Can I send you a picture to see if you tested these please ?
Send a pic. I don’t think I have tested the plates. If they are from before the year 2,000 they are likely leaded. TamaraRubin@mac.com
This may sound stupid, but would it be possible to just remove the decoration outside the dish in order to keep using it safely?
Hi Isabel,
Possibly? I don’t know. I haven’t tried.

Does that mean all Cornflower Corning Ware (the ones without stamping on the bottom) are safe to use?
I would love to know if this was pyroceram or stoneware. If you ever find out, or if the original person who sent the pan reads through these comments, please let us know.
Tamra, I tested the Blue Cornflower today with the 3M kit like you test the green bowl in your video. It is the Pyroceram and probably mid 70ās or 80ās which might be of interest to you Asya. I couldnāt get the q-tip to turn anything but yellow and tried 3 times. I also tested some other stuff and only one thing turned the q-tip pink, and that was a lightly glazed Mexican bowl like you describe that would be suspect. The one pink tip was very definite so I feel like the other stuff may be ok. The only thing I wonder about is my 2 old Tupperware pieces. They didnāt turn the q-tip pink but the liquid where I rubbed, left a pinkish color on the Tupperware bowl itself. It was one of those old avocado colored ones. Do you think that means it has lead even though the q-tip didnāt turn pink? Can the 3 M test find lead in Tupperware, or is that something you have to have the machine for? I know it sure worked on the Mexican bowl!
Thanks so much for all your help!
Hi Jenni,
The swabs are not generally useful for testing any kind of dishware. Please read this post for context. Thanks for commenting.

Thank you for sending that information. Thereās so much info on your site I sometimes canāt find it all so Iām glad you sent that.
I have a couple of questions. First why is there lead in alll these products? Is needed to make the paint stick to the product ormake the color brighter? Is there something else that can be used?
And second is this lead allowed by the federal government because of the work of lobbyists or the cheaper price of using the lead, etc.
I’m the mother of three grown children and four small grandchildren and now I am going on the soap box about this. Grateful I have found you.
Personally, I feel like itās because the lead made the product stronger, (thus the ability to go from fridge to stovetop?) I think that may be why leaded glass can be so thin, yet strong. Tamara would know more about this than I would.
I purchased the solid light plain cream colored
Corelle dishes in 2005-2006. Would those contain lead? I have a huge set and also a cabinet full of various size Corelle Cornflower blue cookware. I dislike having to get rid of all of these as I use one at almost every meal. They were purchased at all kind of places so I have no idea of age etc. Are they safe to use? Thank you!

Thank you so much for this info!
Hi Samantha. Thanks for commenting! You are very welcome. Let me know if you have any questions as you dig around my site a bit!

I have 3, white, corn flower design on the exterior Corningware casseroles. All are from 1968. Marked on bottom : 9ā P-9-B; 4ā R-41 petite pan; 1 1/2 quart (other marks worn off this one). The two larger casseroles have glass covers. The petit pan has a plastic cover.
Can you tell me anything about the safety of these? Thank you very much for the important work you do. Evelyn
