of traditional etching methods, their dangers, subsititute safe electrolytic
and electrochemical methods: Galv-etch and Galv-on, Bordeaux etch, ink-ground,
fractint, vegetable cleaning agent and other non-toxic ecologically safe
methods and materials. Extract from GREEN PRINTS
by Cedric Green published by Ecotech Design, Sheffield, UK. - a handbook
on new methods for non-toxic intaglio etching and metal plate printmaking,
featuring the technique of Galv-Etch, a modern development
of the 19th century electrolytic technique of Electro-Etching,
and introducing Fractint and other alternative
methods avoiding the use of solvents and chemicals harmful to health and
to the environment.
