The article indicates that the Magnalite brand is owned by World Kitchen. However, another company, American Culinary, claims to have bought the "the proprietary metal formula, trade secrets, designs, blueprints, tooling, molds, patterns, manufacturing facilities, intellectual property, property rights, [and] goodwill of Griswold and Wagner," and sells Wagner cast iron, the "original" Magnalite, Magnalite Professional, and the newer Magnalite Masters (introduced shortly before GHC went belly-up). They were still responding to e-mail as of about six months ago.

Pyrex
This article says that Corning switched from borosilicate glass to soda-lime glass for their Pyrex products in the 1940s. The article on Pyrex says that the change in Pyrex was made at the time of the World Kitchen spinoff in 1998. This needs further investigation to verify which is correct.

Good point. No clue on how to verify it either way, short of analyzing my inherited pyrex dishes and that isn't going to happen if it is a destructive process. ;)

No one seems to know for sure. See the Snopes source. Corning started switching in the 1940s according to World Kitchen, but sources disagree on when the switch was completed.

These two companies merged but I'm unclear how best to handle their two separate wiki pages. Corelle Brands has a much longer history and I believe this one should be renamed "Instant Brands" but unclear how to handle the content of the other, existing page. Thoughts, suggestions, etc?

According to this article
(dtd Feb 03, 2021), "Corelle Brands" simply renamed itself to "Instant Brands". Since they are actually one and the same companies I would think a simple redirect from one to the other would suffice.
Instant Brands lists seven different brands it produces (not including EKCO), some of which have their own Wikipedia page. Other than the initial production of Corning glass bakeware in 1915 and a couple of sales/merges there is very little info on how all these brands were born and came together. It is sorely needed.

It gets confusing. Corelle Brands and Instant Brands were previously two unrelated companies. They merged and retained the Corelle Brands name. Then, much later, they changed their name to use Instant Brands as the global company name instead.
