Electrolytic Etching of Brass.
"A while ago I saw Mark Frauenfelder's limited edition Moleskin
notebooks on BoingBoing and immediately thought of using the
electrolytic brass etching process that I've been experimenting with to
make some similar notebooks to give as gifts this year."
Here's a technique I adapted for easily impressing images into brass
plate. I say "impressing" but what I'm actually doing is
electro-chemically etching the brass. Here's the process:
First we use a laser printer to print a negative of our image onto a
sheet of inkjet glossy photo paper. Yes, I did say inkjet paper, this
is an "off schedule," use as they say in the pharmaceutical biz.
Next we throughly clean a piece of brass with Scotch Bright and then
scrub it with alcohol until it's completely clean. Several alcohol
scrubbings will be needed to remove all of the dirt.
