Ridgefield — Ridgefield High School’s chemistry, art and shop classes worked together to build a brick kiln. Following an archeological dig in Spain last summer, chemistry teacher Kara Breuer and art teacher Tamara Hoodenpyl became inspired in learning about ninth and 11th-century pottery and glazes. Chris Shipp’s shop class helped build the outdoor wood-fired kiln, Hoodenpyl’s art class created and glazed the tiles and Breuer’s class led the chemical analysis after the tiles were fired. Students learned art history, building techniques and elements of chemistry.
