Lift Ground Test 3

Test Summary
I mixed a small amount of the Edinburgh lift and decided not to dry the ground on the hot plate. I allowed the copper plate to dry in the open air so the lift does not become baked onto the plate.

Date: October 7, 2009
Researcher’s Name: Elena Betke Brunswick
Plate Material: .032 Copper
Plate Size: 5in x 7in
Room Temperature: 66° Overcast

Plate Preparation
I degreased with soy sauce that was rubbed onto the copper plate using a piece of rolled felt, rinsed and then dried with a clean rag and blow dryer. The degreasing was done two times. I mixed half the normal amount of Edinburgh Lift (1 teaspoon masking fluid, 2 eraser tips gouache, and one quarter teaspoon water.) I painted the lift ground unto the copper plate for 30 minutes using a variety of different diameter brushes and allowed the plate to air dry for 40 minutes. I poured the Z-Acryl hard-ground emulsion across the copper plate and caught it in a water tray. I stood the plate up vertically and allowed it to dry in the open air for 5 minutes. I placed the copper plate in the hotbox for 30 minutes to harden the Z-Acryl. After the hardening I placed the copper plate in a bath of warm water. The ground came off quickly and easily by rubbing it with gloved hands. I applied an aquatint in five passes to the plate with a Paashce airbrush set at it’s finest setting. The aquatint was air dried for 5 minutes and placed in the hotbox for 20 minutes.
