CorningWare, a household name synonymous with high-quality cookware, has been a staple in many kitchens for decades. However, concerns about the safety of CorningWare products have led many to wonder: when did CorningWare stop using lead? In this article, we’ll delve into the history of CorningWare, explore the use of lead in their products, and provide a detailed timeline of the company’s transition to lead-free manufacturing.
A Brief History of CorningWare
CorningWare was first introduced in 1958 by Corning Glass Works, a company founded in 1851 by Amory Houghton. The brand quickly gained popularity for its innovative, non-reactive, and durable cookware made from a unique glass-ceramic material called Pyroceram. This material was resistant to thermal shock, making it ideal for cooking and serving.
The Use of Lead in CorningWare
In the early years, CorningWare products did contain lead, which was used as a flux to reduce the melting point of the glass-ceramic material. This made the manufacturing process more efficient and allowed for the creation of intricate designs and patterns. However, as concerns about the health risks associated with lead exposure grew, CorningWare began to explore alternative manufacturing methods.
The Transition to Lead-Free CorningWare
In the 1970s, CorningWare started to phase out the use of lead in their products. This transition was driven by growing concerns about the safety of lead and the introduction of new regulations. In 1971, the U.S. government banned the use of lead in paint and other consumer products, and CorningWare responded by developing a new, lead-free glass-ceramic material.
Key Milestones in CorningWare’s Transition to Lead-Free
- 1972: CorningWare introduces its first lead-free product line, called “CorningWare II.”
- 1978: CorningWare begins to phase out the use of lead in all its products.
- 1987: CorningWare completes its transition to lead-free manufacturing, with all products meeting or exceeding federal safety standards.
What Does This Mean for Consumers?
If you’re a CorningWare enthusiast or collector, you may be wondering what this means for your cookware. Here are a few key takeaways:

When did CorningWare stop using lead in their products?
CorningWare stopped using lead in their products in 2008. However, it’s essential to note that the company had been reducing the amount of lead in their glazes since the 1970s. The U.S. government had been implementing stricter regulations on lead use in consumer products, and CorningWare had been working to adapt to these changes. By 2008, the company had successfully developed a lead-free glaze that met their high standards for quality and performance.
The transition to lead-free glazes was a significant milestone for CorningWare, as it allowed the company to continue producing high-quality, safe, and durable cookware for consumers. The new glazes were made from a combination of materials, including silicon dioxide, aluminum oxide, and zirconium oxide, which provided excellent thermal shock resistance and durability. As a result, CorningWare’s lead-free products have become a staple in many kitchens, trusted for their performance, safety, and eco-friendliness.
What are the health risks associated with lead in cookware?
Lead is a toxic substance that can pose serious health risks, especially when ingested or inhaled.
