What is Pyrex made of?
Corning licensed the Pyrex brand to a company called World Kitchen—now known as Corelle Brands—in 1998, and by nearly all accounts, all Pyrex cookware sold in the United States after that year has been made of tempered soda-lime glass. This is where the controversy really heats up.
Why is Pyrex so popular?
If the temperature change happens rapidly materials like glass can shatter or seem to explode. Resistance to thermal shock is part of why Pyrex became so popular for cookware; you could move a hot glass pan into a cool spot without worrying about it cracking or shattering.
What happened to Pyrex glass?
Several Pyrex customers who say they experienced exploding glass incidents themselves filed a class action lawsuit in June 2018 alleging that Corelle Brands inadequately warns consumers of the thermal breakage issue and then hides behind warnings and warranties when incidents occur.
Why does Pyrex pan explode?

When did Corning's Pyrex pans expire?
These dates are important because Corning’s patent on the borosilicate glass used to make Pyrex pans expired in 1936. At that time, the company developed a new formula for aluminosilicate glass, which it used to create a line of frying pans called Pyrex Flameware. (This line was discontinued in 1979.)
Overview
Pyrex (trademarked as PYREX and pyrex) is a brand introduced by Corning Inc. in 1915 for a line of clear, low-thermal-expansion borosilicate glass used for laboratory glassware and kitchenware. It was later expanded to include ware products made of soda-lime glass and other materials.
In 1998, the products division of Corning Inc. responsible for the development …
History
Borosilicate glass was first made by German chemist and glass technologist Otto Schott, founder of Schott AG in 1893, 22 years before Corning produced the Pyrex brand. Schott AG sells the product under the name "Duran".
In 1908, Eugene Sullivan, director of research at Corning Glass Works, developed Nonex, a borosilicate low-expansion glass, to reduce breakage in shock-resist…
Composition
Older clear-glass Pyrex manufactured by Corning, Arc International's Pyrex products, and Pyrex laboratory glassware are made of borosilicate glass. According to the National Institute of Standards and Technology, borosilicate Pyrex is composed of (as percentage of weight): 4.0% boron, 54.0% oxygen, 2.8% sodium, 1.1% aluminum, 37.7% silicon, and 0.3% potassium.
Use in telescopes
Because of its low expansion characteristics, Pyrex borosilicate glass is often the material of choice for reflective optics in astronomy applications.
In 1932, George Ellery Hale approached Corning with the challenge of fabricating the 200-inch (5.1 m) telescope mirror for the California Institute of Technology's Palomar Observatory project. A previous effort to fabricate the optic from fuse…
