Etching with Copper Sulphate
On this one day workshop you will explore the basics of etching metal printing plates such as zinc and aluminium using hard wax grounds and copper sulphate solution.
Etching is an intaglio printmaking process where etched lines or grooves are created on a metal surface which are then inked up and printed from using an etching press. Using copper sulphate to etch is a much safer and less toxic alternative to using traditional nitric acid to etch copper plates.
