Etching Copper with Ferric Cholride
with artist Sara Blumenstein

Artist Sara Blumenstein is a designer and inventor. She lives and works in Great Neck, New York.

"In my life, science and art have always been inextricably connected. My educational qualifications include an MS in Science Education and certification to teach Art through high school.

As a middle school science teacher, I was always looking for ways to make the science meaningful and marry the learning to real life. Chemical etching turned out to be a great activity for this purpose. As a designer, a minimalist, I am interested in how to get the most from the least. When I first tried using Ferric chloride to etch, I was surprised at the good results, even for a beginner. The simplicity of the process really hooked me ."

Ferric chloride is an easy to use, fairly benign, chemical for etching images into copper. Rubber stamps, permanent markers, and printer transfer paper can all be used to create complex designs. You never really know what you will get when the piece is cleaned up, but it’s usually a nice surprise.

During 150 minutes of the hands-on workshop, artist Sara Blumenstein guided participants to create an etching art using copper and other tools. Participants created wearable art using their finished etching ornaments to take home. We also did a science experiment during the workshop and saw scientist Phil Cook's inventions.
