In this workshop Penny Brewill will share the process of etching aluminium metal plates with copper sulphate. A copper sulphate, salt and water solution provides a low-toxic environment to etch aluminium plates – a safer and more accessible alternative to ferric and nitric acid solutions used for etching zinc and copper plates. The process allows for a greater range of mark making including fine line drawing to expressive, painterly textures.
