Etching – Printing technique in which a metal plate is first covered with an acid-resistant Material, then worked with an etching needle to create an intaglio image. The exposed metal is eaten away in an acid bath, creating depressed lines that are later inked for printing. This technique was thought to have been developed by Daniel Hopfer (1493-1536). Etching surpassed engraving as the most popular graphic art during the active years of Rembrandt and Hercules Segher in the 17th century..
As I am still working on the NURTURE project focusing on growing, mushrooms, plants and recently on soil I wanted to produce image to to relate to that.
1. prepare the edges by beveling them at an 45 degree angle with a metal file so the edges slope
2. degrease plate with chalk-water mix
3. Coat your plate with resists called ‘grounds’
4. blacken the plate with candle smoke
5. cover sides with straw hut an back side with tape
6. make marks
7. dunk it to the acid bath for cca half an hour (stroke with feather occasionnally)
8. clean the plate
9. cover plate with etching ink and print..
Some of the etchings of mine I have done last year:
And here is, what I produced today:
