Saline Sulphate & Electro- Etching Workshop Regional Print Centre Wrexham

Saline sulphate and electro-etching with Don Braisby

 1/2 June 2017

10:00-16:00

This workshop will teach two etching processes that can be used to etch at home or in a classroom situation, these are saline sulphate and electro-etching.

Both processes have been described as being ‘safe etching’ however in this workshop we will focus on their potential for alternative mark making rather than on their non-toxic credentials. Don Braisby who is teaching the workshop is completing his doctoral thesis on electro-etching.

 Workshops aim:

  • Provide a simple introduction to the theory and practice of electro- etching.
  • Introduce the equipment needed for electro-etching and plating, how to set it up and use it safely.
  • Creative plate making, resists and stop outs
  • Preparation and etching of plates.

 Objectives:

  • Participants will have gained a working knowledge of both saline sulphate and electro-etching
  • To make and proof at least one plate in each process.
  • Introduced to electroforming and electrotyping as a potential process in sculpture and printmaking.
  • provide feedback for use in research.

 Non-members £120.00/Members £75.00

Electro-etching steel plate

One of the things I like about etching aluminium with saline sulphate is the great depth of etch that it is possible to get. I’ve wasted an awful lot of research time trying to get the same depth of  etch on aluminium with electro-etch. I’ve now found I can get the depth of etch I want by electro-etching mild steel, it takes a while but it is worth it.

Print from electro-type plate and two more prints

I made a silicon mold from one of my old plates, coated the inner surface with conductive paint and placed it as a cathode in an electrolytic cell using copper sulphate as an electrolyte. Copper formed on the inside of the mold making an exact copy of the original plate.

another day in the print studio making prints

I took four prints from each plate. The textures achieved with electro-etch respond best to being treated the same way as collagraph matrix. I’ve also been using a technique that Andrew Baldwin describes as ‘double drop’, a plate is first printed in one colour then over printed in a second colour from the same plate.
