We took our four plates from a week ago and etched them in ferric chloride for 10 mins. First we applied an acrylic airbrush aquatint to half of the surface on plates 1, 2 and 3, the plates with the silicon dioxide ground.
Plate 4 remained as just a hard ground layer.
We wanted to compare the effects of this ground to those achieved with a white ground. We put the plates in the ferric tank for 10 mins in rinsed them in a bath of water. Upon exposure to water the ground started to immediately peel away.
We noticed that the aquatint appeared to have been blocked by the ground leaving no effects.
We printed the plates as follows:
Paper: Hahnemuhle Copperplate
Ink: Graphic Chemical INK CO Bone Black #514C etching ink
Modifier: burnt plate oil
Wiping: Tarlatan and newsprint
