Sometimes it's obvious from the design...the overall shape, especially
the handles. Some of our older Pyrex is thicker/heavier than the same
diameter pieces now available. And our Corningware is all 'cornflower'
design. The all-white styles are a bit more recent.

Interestingly, the French-made CorningWare I saw last month, included
pieces with the old cornflower design, as well as the all-white stuff.
None of the other patterns, though (of which there were a bewildering
variety).

I have one old, scratched cornflower piece that belonged to my mom. Then
when I lived on Cape Cod, at least 12-13 years ago, a Woolworth's went out
of business. I bought a very large set in the pansy pattern. Daughter
dropped one of the smaller pieces and it broke. I was able to replace it
and also got another piece from Ebay. I think they were used but you
couldn't tell it.

I also recently bought a couple of the white pieces because I needed more
casseroles in the smaller sizes since it is just daughter and I here most of
the time. I have had no problems with them but I am careful with them. I
read somewhere that you should not even set them on the top of the stove
when you take them from the oven. I do put them there but on a burner.

Yes, the cornflower design and some others stand out and are old.
So ALL of the white Corelle was produced after the change? I
obviously need to look into Pyrex (especially). I have quite a
lot of it, old mixed with newer, and I have NO idea what vintage
much of it is!

I've always been a bit nervous about this. I love my glass pans, but
they are made by Anchor Hocking and about 5 years old... basically
"guaranteed" to be the soda glass.

Isn't the borosilicate Anchor Hocking called 'Fire-King'? Or are they
using that name for soda-lime glass now?

I'm wondering if there is a site that would tell the different
years these were made. Now that would be nice to know.

I started a search. I don't know whether there is such a thing
and don't have time to explore it further now. It would seem that
the plain items are the most difficult to date.

I've seen booklets on eBay, which claim to have information on the dates
of the various patterns. Apparently, some of them are considered
'collectible'.

Yes, I was thinking that. Now I kind-of wish I had kept more of
my mother's ugly old stuff.

PS. Here's a site on Pyrex etc. I am not seeing an area devoted
to dates, but it is interesting nonetheless. Note the books to
the right of the page. I wonder whether they contain dates? I
will take a quick look when I next see such a book in person.

I have a couple of those two sided dishes. One is missing the lid. They
are great for when I want to fix two different vegetables for dinner. And I
used the lidded one a lot to keep my husband's food warm when he got home
late from work. I got one at a yard sale in PA and another from Ebay.

No, definitely not.

I have all-white pieces that are more than 20 years old.

Same here.

However I don't understand what "change" is under discussion. Corelle
is as far as I know made from the same laminated tempered glass from
which it has always been made.

It's true that World Kitchen ditched Pyroceram for a while, but it's
back as "Corningware Stovetop". However Corelle was never made from
Pyroceram.

Yes, they used to make some that I think was called French White. However I
think it looked different than what they make now. I believe the old stuff
had like...ridges that ran vertically around the sides. I can picture it in
my mind. Just can't describe it well.

Yes, French White CorningWare has vertical ribs around it. It
post-dates the squareish ones with grips on each side. The new
'CorningWare' has a version of the ribbed French White, but in stoneware.
I have a number of pieces of the traditional shapes in white, as well as
French White, a few Cornflower, and some yellow pieces, which were only
produced for a short time.

Thanks. I thought some was older. In fact, now that I think of
it, my sister has had some for MUCH longer than 20 years. It
seems to me that there was a hiatus when one could barely find and
dregs of it in the stores, and then it reappeared. That is
probably when it changed. I need to compare the writing on my
pieces. Maybe there is a difference.
