Yesterday evening I ran a workshop at the Regional Print Centre on monoprinting as serendipity, would have it, as part of my PhD. research into electro-etching I had come across this series of lectures given by Hubert von Herkomer. In one of the lectures he describes the process of making an electrotype copy of a monoprint …

This is not a how to do it! Just a bit of fun.
“If two plates of copper be connected with the opposite ends of a voltaic battery, in a vesessel containing very dilute sulphuric acid, the plate connected with the copper of the battery will be attacked by the anion oxygen which is released during the decomposition of the acid”. “By alternately exposing the plates to the …
Describing electro-etching in 1852 “If, for instance, plates of copper be covered on any part of their surface with a stratum of varnish, that part will be excluded from the line of action, while all else is being consumed. Advantage has been taken of this, by coating the plate with proper composition and then tracing …
This etching process was first described by Cedric green on his website and by Alphonso Crugera in his recently published Handbook. In this process the cell becomes a self etching battery. When two metals with different potentials are placed together in electrical contact in an electrolyte, one metal will act as anode and the …
Using Sodium Chloride as an Electrolyte to Etch Aluminium In theory this is what should be happening in this cell. But the gas coming off the anode does not have the typical chlorine smell.As electrolysis takes place it would be expected that sodium hydroxide (caustic soda) would develop in the solution and that this would …
