Is this good corningware?

[Martijn]

Hello. I've bought this dish for 50 cents today at a flee-market. I was very pleased to be able to read 'corning ware' in the light once we got outside! But I wanted to know if i can rely on these markings if it is the real deal. The bottom is smooth.

Corning Ware is not Corningware Pyrocream. Pyrocream is the type that was made to go from the freezer to the oven without shattering.

There was a detailed thread about pyrocream a ways back. I will look for it.

Duhhhh when in doubt look in the library!!!

Your item number has an A prefix. It is not pyroceram. You want a P prefix on the item number.

I read those, but was still not sure. Now i know, it's not pyroceram, Have to look for the P.
Allthough it has that smooth bottom and 'glass like appearance' that was talked about and i will keep on looking for the good stuff.
Thanks for the replies guys!

I did pyrolize a hand full of filter papers in it yesterday, and that went great, i was probably just lucky...
Safety first!

But then why is the post 1972 Pyroceram marked with an A? As mine is? that's kind of confusing.
Heating with a torch and tossing a bunch of cold water in it, is not really the test i want to perform.

from the thread:

"Further breakdown of the letter codes for corningware pyroceram dishes.

A--post 1972"

I could be in error but P marked items are common in my area.

I know Corning changed their formulation for their clear glass items in the US to an inferior formula, no longer borosilicate. I just did not trust the newer items

Hey Martijn,

We have our very own Pyroceram in our part of the world! Look for Pyroflam, if i dont beat you to it at the flea markets They guaranteed no breaking from temperature changes, excluding the glass lids.

I have found this trying to find an alternative for the 'known' Corningware our colleages from abroad use. Check out the picture below!

Hope this helps,
