Spotlighting trends beginning in the 1920s to create new glass colors utilizing rare earth oxides that varied when viewed in natural or artificial light, Amy will tract the evolution of these technological and artistic developments in Steuben Glass Works under Frederick Carder’s artistic leadership and other contemporary American and European glass companies that were racing to develop their own versions. In examining both the dynamic nature of the glass that changed colors in different light and the increased global speed at which ideas and technology were transmitted between American and Europe, this talk contextualizes the kinetic characteristic of rare earths glass within the larger Art Deco period’s focus on movement and animation.
