What Is Pyrex?

Pyrex is a type of borosilicate glass that is used in many household objects such as baking dishes, measuring cups, and lids for food containers. The material was first created by corning glass works in the early 1900s and was initially used in laboratory glassware.

Pyrex is transparent, and its heat-resistant properties make it perfect for cooking and storing food in the microwave.

History Of Pyrex

At the turn of the century, glass and ceramics were essential materials for science and industry. Glass manufacturers looking for new markets experimented with producing heat-resistant glassware like lab equipment. In 1915, corning glass works developed a process for making borosilicate glass, which they named pyrex.

The product was a hit, and by the early 1920s, pyrex was available to consumers in the form of cooking and baking dishes.
