In this article, we will delve into the history of Corelle, the science behind lead in dinnerware, and provide guidance on how to assess and mitigate potential risks associated with using older Corelle products.
Introduction to Corelle and Its History
Corelle is a brand of glassware and ceramic tableware that has been in production since the 1970s. It was initially introduced by Corning Glass Works (now known as Corning Incorporated), with the first pieces being launched in 1970. The name “Corelle” is derived from the combination of “Corning” and “elle,” a French suffix suggesting a product of high quality and elegance. Corelle dinnerware quickly gained popularity due to its lightweight, resistant to scratches and breaks, and the unique Vitrelle glass technology that made it both durable and beautiful.
Vitrelle Technology and Corelle’s Popularity
The innovation behind Corelle’s success lies in its Vitrelle technology. Vitrelle is a type of tempered glass that is made by laminating three layers of glass together. This process involves sandwiching a thermoplastic layer between two layers of glass, which are then thermally treated to create a strong and durable product. The result is dinnerware that is not only aesthetically pleasing but also remarkably resilient against thermal shock and mechanical stress. This technological advancement, combined with attractive designs and patterns, catapulted Corelle to the forefront of the dinnerware market, making it a favorite among consumers worldwide.
Understanding Lead in Dinnerware
Lead is a toxic substance that has been used in various products for centuries, including in the glazes of ceramics and glassware.
