Glass etching comprises the techniques of creating art on the surface of glass by applying acidic, caustic, or abrasive substances. Traditionally, this is done after the glass is blown or cast, although mold-etching has replaced some forms of surface etching. The removal of minute amounts of glass causes the characteristic rough surface and translucent quality of frosted glass. Carrie Gustafson is a master of glass etching. Her work speaks for itself, but she describes the process beautifully in the video below. It would be great to spend a day with her and watch her process in person. Maybe we can get up to Cambridge, MA to watch her one day. Please?
