I am taking an copper plate etching class (Intaglio, amigo) taught by Alex Chitty (she rules!) at Spudnik Press here in Chicago (Spudnik rules too!) tuesday and thursday nights
...been about fifteen years since I have done this process, totally excited to be doin it again!
tuesday prior I started with two 5"by 8" pieces of flattened roofing copper
cleaned em, beveled the edges, put hard ground on one (asphaltum?)
and went to town with some needle tools; then thursday while the hardground plate was in the acid bath I put soft ground on the other (sticky asphaltum?) and drew with a pencil and litho crayon on a piece of paper on top of the plate, the pressure from the marks on the paper lifted the soft ground off, in about the space of three hours I had two fully etched and cleaned plates and was able to ink and proof them on BFK paper, whoa, I still was able to go out later and drink beer!
yipes these pictures are out of order but you get the idea right?
