First Copper Etching

My co-teacher, Brian Borlaug, works almost primarily in copper etching, so for our print survey class he wanted to cover copper for the intaglio section. I've only ever worked with zinc, and the etching class at CSULB also is done with zinc, so I took the opportunity to learn with copper along with the students. We had each of the students do a tiny 3" by 3" copper plate first to get the hang of the medium, in addition to their big plate for the assignment.
