Pyrex etymology

Etymology:

The word "Pyrex" is derived from two Greek roots:

• Pyr (πυρ): Fire
• Ex (εξ): Out of

Therefore, "Pyrex" literally means "out of fire."

Meaning:

Pyrex is a brand name for a type of heat-resistant glass cookware that is made from borosilicate glass. Borosilicate glass has a low coefficient of thermal expansion, which means that it can withstand extreme temperature changes without breaking. This makes it ideal for cooking, baking, and serving dishes that involve high temperatures or sudden temperature changes.

Origin:

Pyrex was first developed in 1915 by Corning Glass Works, a company based in Corning, New York. The original Pyrex products were designed for use in laboratory settings. However, in 1918, Corning began to market Pyrex for home use. Pyrex quickly became a popular choice for cookware due to its durability and versatility.

Other Facts:

• The name "Pyrex" was initially used as a trademark only for borosilicate glass products made by Corning Glass Works.
• Over time, "Pyrex" became a generic term for any type of heat-resistant glass cookware, regardless of its manufacturer.
• Corning Glass Works sold the Pyrex brand to World Kitchen, a home appliance company, in 1998.
• The Pyrex brand is now owned by Newell Brands, which acquired World Kitchen in 2016.
