It is the same company that sold cheaper soda-lime glass under the name "Pyrex". Pyrex as a brand used to mean "borosilicate glass", a type of glass known for its superior resistance to thermal shock.
- ksherlock 3y agoCorning started doing that in the 1980s. Then Pyrex was spun off to Correlle in 1998. Then Correlle merged with InstantPot in 2019.
- hedora 3y agoIt’s strange instant pot would burn their brand by being associated with pyrex. Just last week, I was talking to an older person, who commented that she kept somehow shattering her pyrex. I guess an older piece finally broke a few years ago, and she hadn’t heard about it. Anyway, it continues to be a safety hazard. Shame on corning for making the change (without just killing the brand name). My instant pot’s fine though. I dropped the lid from 10 feet on to concrete, and the heat sheild cracked, but it didn’t affect the seal or safety.
