In recent years, printmakers have engaged in finding non-toxic materials to replace tradional ones that were noxious and problematic in a teaching environment. Resulting from such efforts, exciting and cost effective materials such as water based grounds and films used originally in the silicon chip industry have found their way into printmaking labs around the world. At City College of San Francisco, Ocean Avenue Campus, students are learning how to use such materials in the exploration of their ideas and so further expand upon the rich basis of some many people's efforts.

The above links provide you with information that I compiled while participating in a non-toxic printmaking workshop that was taught by Elizabeth Dove at the University of South Dakota, Vermillion and organized by Frogman's Print Gallery.
