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 …

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.

Adding a new print to a growing series

The plates that these prints are made from started life as electro-etch test pieces. They are all made from electro-etched aluminium. It is a soft metal that etches deeply and in the areas of open bite provides a tooth that holds ink really well. Peter Wray, in his article on saline sulphate etching in Print Making …

Etching Is The Control Of Corrosion

This zinc plate has been allowed to corrode all the way through in places. The original batteries made to produce electricity in the 1830s were made by hanging a plate of copper and one of zinc in a solution of copper sulphate. Thomas Spencer observed that copper was deposited on the copper plate (the cathode, …
