New Leptat® (Etched)

Etched glass has served a unique purpose for hundreds of years, transmitting natural light as clear glass does, while providing a work of art that screens one area from another.

Patented by Bernard E. Gruenke, Jr., Leptat® is the signature etched glass of CSS. Unlike the more typical frosted etch that is produced by an abrasive etching technique, Leptat® creates a deeply etched, crystalline surface of varied textures.

“Leptat® ” takes its name from the Czech word meaning “to etch,” because the technique was inspired by a Czechoslovakian glass exhibit Bernard O. Gruenke, Sr. viewed at a past World’s Fair in Osaka, Japan. Bernard and his son, Bernie, Jr. experimented with new methods of glass etching until they produced the desired effect of dramatic, expressive etching.

Abstract, figural, contemporary and traditional designs have been executed in Leptat® glass. A secondary design or pattern is sometimes etched more lightly into the negative areas, for further interest. Gold leaf or colored enamels also can be inlaid to highlight the designs. The Leptat® technique allows the glass to reflect light from many surfaces, like a jewel-cut gem. As with stained glass, Leptat® lends an aura of beauty and mystery to a variety of spaces.
