First manufactured by the Corning Glass Works in 1915, Pyrex was infused with innovation from its inception. The original intention was to create a glass that could withstand drastic temperature changes without breaking, a significant concern in a time when kitchen technology was evolving rapidly. Pyrex's unique borosilicate glass composition was revolutionary; it combined durability with transparency, allowing cooks to monitor their ingredients easily. Over the years, this glass became synonymous with kitchen reliability, paving the way for an array of products, including measuring cups, baking dishes, and storage containers.
