A springtime tradition at Standard Clay is the annual High School Students Exhibition at the ClayPlace@Standard gallery. Area art students and their teachers look forward to selecting their best pieces, showing them to a wider audience, and facing the scrutiny of a professional juror. This year’s juror, Jerry Wagner, is a paradoxical mix of artist and technician who is not only an accomplished potter but a veritable fire wizard. Wagner’s years of experience in the industrial kiln industry lends a unique perspective to his eye for the seemingly mysterious process of combining earth, chemicals, and heat.
