World Kitchen did not change the product composition for Pyrex glass bakeware.
Pyrex glass bakeware has been made – first by Corning Incorporated and now by World Kitchen – using the same soda lime composition and heat-strengthening process for more than 60 years.
World Kitchen has always manufactured Pyrex glass bakeware in the U.S. and our packaging proudly displays the American flag and the “made in the USA” label.
World Kitchen, which purchased the Pyrex consumer products business from Corning Incorporated in 1998, is a U.S. company based in Rosemont, Illinois.

You're being dishonest, as is that World Kitchen webpage. It presents findings favorable to the company, but ignores facts that are not. For example, it correctly states that the he U.S. Consumer Products Safety Commission found US Pyre safe to use. Yet it doesn't address the undeniable fact that the European borosilicate glass is more resistant to heat changes. When World Kitchen claims that soda-lime glass is more resistant to breakage, don't you think it should also mention the downsides? Indeed, we buy Pyrex for heat-resistance, not for impact-resistance. Even Pyrex's name means heat. So don't you think the webpage should admit that there really is a difference?
Most damning, the very Snopes article that World Kitchen claims support it actually says something else. The company insists that Corning and World Kitchen has used soda-lime glass for 60+ years. The ONLY support for that claim in the Snopes article is a statement from World Kitchen itself! And to a lesser extent, Anchor Hocking's claim that borosilica was phased out in the US by the 1980's. Note, however, that both Anchor and World Kitchen benefit from this claim so their statement isn't objective. What World's webpage ignores is an OFFICIAL STATEMENT FROM CORNING, who has nothing to gain or lose since they no longer own Pyrex.
From Snopes, which World Kitchen cites:
"Sarah Horvath, a Corning spokeswoman, says Corning made Pyrex out of both soda lime and borosilicate at several locations before selling the U.S. business to World Kitchen in 1998, but provided no more details. P. Bruce Adams, formerly an executive scientist at Corning, says that borosilicate was still being used to make Pyrex when he retired in 1987.
Both Corning's official spokesperson and a Corning scientist EXPLICITLY contradict World Kitchen's claim that Corning had switched to soda-lime 60+ years ago!!! The spokesperson even said that they were still using borosilicate at the point of sale in 1998. Why didn't World mention that on their website???
While World Kitchen may not have changed the formulation, and merely discontinued the use of borosilicate, the fact remains: World Kitchen's actions made a thermally-safer glass unavailable to Americans. And that's what this debate is about, isn't it?
For reference, here are the websites in question:
World Kitchen's Official Page on the Pyrex "myth"
The Snopes article World Kitchen claims as support. Yet, it clearly indicates that Corning was still using borosilicate when it sold Pyrex in 1998.
