copper plate printing on plaster - 石膏刷り

愛知県立芸術大学の井出先生の石膏刷りワークショップに参加しました。石膏に版画が刷れると全く知りませんでした。とても貴重な経験でした。
We had a special lecture and workshop run by Sotaro Ide, a printmaking professor from the Aichi University of Art, about printing copper etchings on plaster. I had no idea such things could even be done!!!

 Plates were made using bits of plants pressed into soft ground and etched overnight.

 Then they were all inked up and wiped and placed in a water bath to speed up patination. Professor Ide uses the green and blue oxidation of the copper to create monotype-like prints

 The plates were then taped into a cube

And filled with plaster.

Once the plaster dries, remove the plates...

And voila! Copper plate etching on plaster! Incredible!
