Gyrotron Technology, Inc. has filed a provisional patent application for a new technology for glass tempering, one of the primary methods of producing safety glass. The technology utilizes the gyrotron, a very powerful source of high frequency microwave energy. Most safety glass is produced by tempering and/or by laminating.

Tempered glass is used extensively in the automotive and construction industries. Potential advantages of GYTI's technology include; a very significant reduction in energy usage, the opportunity to heat temper thinner glass than can be heat tempered with legacy technology and the elimination of certain surface distortions (waving), thus improving suitability for new applications.
