Coffee And Spit Bite

The plate ready to print

The plate ready to print

More geeky printmaking stuff from last weekend’s B.I.G. Etching course with Andrew Baldwin at Swansea Print Workshop. The aluminium plate was degreased with whiting and soy sauce to get it ready for drawing on with instant coffee solution. I forgot to take a photo of mine being drawn, but Andrew Baldwin has kindly lent me a photo from his forthcoming book (below). Once I finished the coffee drawing I gave it a quick flash in the oven to dry it and then rolled over a layer of Andrew’s B.I.G. etching ground. I baked it for 6 minutes and then bathed it in warm water, which lifted off the areas that had been drawn with the liquid coffee, revealing the areas to take an aquatint and spit bite, which will be the darker areas of the print. Then a quick dunk in copper sulphate solution to etch a light grey aquatint, giving the metal a bit of a ‘tooth’.

 

 

The copper sulphate does some chemistry and reacts with the aluminium, effervescing a red residue. Once that happens, the etching process stops and the residue washed off to reveal the lightly aquatinted surface beneath. Once it dried, I added layers of localised etching using a brush and concentrated copper sulphate solution to darken the selected areas. Then I scrubbed off the B.I.G. ground with non-toxic paint stripper and a stiff scrubbing brush. Now it’s ready to take a first proof, which I will do at an Open Access session at Swansea Print Workshop tomorrow.

    Hi Rosie Finally I found an example of someone doing exactly what I want to have a go at. Particularly on aluminium. I look forward to seeing how it proofs when you put it through the press. I can see though from the text written in the side bar on the right that you have an exhibition on the 20th may (TODAY !!) in Swansea followed by another on the 28th in Bath. I am down as a follower for your blog but dont receive emails for when you do an update. I will have to look into this further. Hope it all goes well for you. If only I could walk normally without chronic pain like I used to ………bloomin frustrating I can tell you. take care

      Hi Aine, there should be a facility to sign up for an email update on my blog – I will check it’s still there. We’ll, not exhibitions exactly, a couple of public art events. Really enjoy public interaction, especially bringing drawing and printmaking to the public. Will be doing some block printing off lino today. I think I blogged a proof print, I will have to check and send you the link. I’m so sorry to hear of your pain, there’s hypermobility and EDS in my family and these chronic pain conditions are so little understood. I hope things improve for you xxx
