Who knew that printmaking with plaster was a thing? In this video, Graham of Diode Press uses nothing but plaster of Paris, a copper plate mezzotint, and ink to create a lovely print piece. He writes:

I’ve come across this method over the years in various articles and by word of mouth and I’d definitely recommend giving it a try! This works with linocuts, etchings, aquatint, or even woodcuts (if you seal the wood first), and requires no press, Barens, or even paper!

Graham cautions:

I’d test it out on an old plate before trying it on something you care about, in case it does not work out how you’d expect or damages the printing matrix.
