Icing Sugar Aquatint #2

Test Summary
This experiment tests a process developed by Andrew Baldwin in which icing sugar is used to create an aquatint. Methods learned from Andrew Baldwin were replicated in this experiment with the intention of producing a smooth, even aquatint. As a result of experiment 1, more icing sugar was used.

Date: June 10, 2011
Researcher’s Name: Cara Borelli
Plate Material: Copper
Plate Size: 6 in x 6 in
Room Temperature: 78°, Low humidity

Plate Preparation
Plate was beveled, burnished, degreased using soy sauce, deoxidized, and BIG ground was applied.

For icing sugar application:
Application 1: Four tablespoons of icing sugar were sieved twice using a tea strainer. The sugar tray in the aquatint box was wiped clean of sugar with a clean rag. A hair dryer was used on high and cold to disperse the sugar throughout the box. The hair dryer hole was covered with a rag while the sugar settled. After 40 minutes the plate was analyzed and it was determined that it was not 60% covered with sugar, and therefore a second sugar application was needed.

Application 2: Two additional tablespoons of icing sugar were sieved twice using a tea strainer. The sugar tray in the aquatint box was not was wiped clean. A hair dryer was used on high and cold to disperse the sugar throughout the box. The hair dryer hole was covered with a rag while the sugar settled. After 35 minutes the plate was analyzed and appeared to be more coated with some sugar having dissolved into the ground.

Baking the ground:
The plate was baked in the oven for 6 minutes and was left to sit in the oven for 30 minutes after baking was complete.

Water Baths:
Water Bath 1: The plate is submerged in nearly boiling water and agitated continuously by moving the tray the plate and water are in. Half of the plate was brushed continuously with a flat soft-haired brush. After five minutes the plate was removed and dried with newspaper.

Water Bath 2: The plate is submerged in nearly boiling water and agitated continuously by moving the tray the plate and water are in. Half of the plate was brushed continuously with a flat soft-haired brush. After five minutes the plate was removed and dried with newspaper. A difference between the brushed side of the plate and the non-brushed side is visible. The brushed side also feels smoother.

Water Bath 3: The plate is submerged in nearly boiling water and left to sit with no agitation or brushing. After 35 minutes the plate was removed and dried with newspaper. When looking through a magnifier, more copper dots are visible than after previous washings.

Water Bath 4: The plate is submerged in nearly boiling water and left to sit with no agitation or brushing. After 30 minutes the plate was removed and dried with newspaper.

This concluded experimentation for 06/10/2011.

Experimentation continued on 06/15/2011.

Water Bath 5: The plate is submerged in nearly boiling water and left to sit with no agitation or brushing. After 10 minutes the plate was removed and dried with newspaper. When looking through a magnifier, more copper dots are visible on the non-brushed side. There is also more texture to the touch on the non-brushed side.

Etching Notes
Plate was etched in a vertical etching tank of Ferric Chloride at 37° Baume.

Timed Application of Mordant
5 minutes.

Removal of Grounds
Ground was removed using Soy Solv and a clean rag. The plate was then rinsed with water and dried with newspaper.

After Bath Evaluation
The plate appears to be more etched than the plate in experiment 1, however the etching is still insufficient.

Inking Methods
The plate was inked with unmodified Graphic Chemical & Ink Co. Bone Black Etching Ink #514. The ink was carded on with mat board scraps, wiped with used tarlatan, and then palm wiped.

Paper Type: Hahnemuhle Copperplate
Paper Soaking Time: 20 minutes
Press Blanket Setup: Sizing Catcher and Pusher, 7.5 pressure, Small Takach Etching Press

Test Conclusion
Weak, uneven aquatint. Brushing the plate was ineffective in further dissolving the icing sugar. Appears as if more sugar and less ground would be more effective.
