Lift Ground Test 4

Test Summary
I am testing the effectiveness of Da Vinci Paint Co. Masking Fluid mixed into the Edinburgh Lift. I wanted to find a less expensive substitute to the Windsor and Newton Mask Fluid. I am not heating the Edinburgh Lift on the hot plate.

Date: October 14, 2009
Researcher’s Name: Megan Klazura
Plate Material: .032 Copper
Plate Size: 4.5in x 6in
Room Temperature: 62° Chilly

Plate Preparation
Initially I cleaned the copper plate with Bon Ami and water made into a paste and rubbed across the plate’s surface. 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 Edinbrugh lift is a mixture of 3 teaspoons of Da Vinci Masking Fluid, 5 eraser tips of gouache, and half a teaspoon of warm water. I painted the lift ground onto the copper plate quickly using a variety of different diameter brushes and allowed the lift to air dry for 30 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. The copper plate was placed in the hotbox for 30 minutes to harden the Z-Acryl. The copper plate was placed in a bath of warm water after being hardened. I rubbed the Z-Acryl away with a wet rag and my bare hands. Aquatint was applied in five passes 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.
