Who invented glass ceramic cooktop?

There isn't a single inventor credited with the creation of glass ceramic cooktops. It was more a process of development and refinement by various companies and individuals over time.

Here's a breakdown:

* Early Development: The basic concept of a glass ceramic material suitable for high temperatures emerged in the early 20th century. Companies like Corning Glass Works (now Corning Incorporated) played a key role in developing these materials, initially for industrial applications.

* First Cooktops: In the 1950s and 1960s, companies like Schott AG (Germany) and Corning began developing glass ceramic cooktops for home use. Schott's Ceran brand was particularly influential.

* Refinement and Innovation: Over the following decades, there were ongoing improvements in the technology, including the development of:

* Induction cooktops: These use magnetic fields to directly heat cookware, offering faster cooking times and greater energy efficiency.

* Touch controls: Replacing traditional knobs with touch-sensitive interfaces for easier control.

* Various design features: Different shapes, sizes, and colors to meet diverse kitchen aesthetics.

Therefore, it's more accurate to say that glass ceramic cooktops were a result of collective innovation by multiple companies and researchers. While specific individuals may have made crucial contributions, it's difficult to pinpoint a single inventor.
