Researcher’s Name: Amelia Vottero
Plate Material: .032 Copper
Plate Size: 4 in x 3 in
Room Temperature: 77° F
I degreased the plate with Bon-Ami and water made into a paste. The paste was rubbed across the plate surface and rinsed away with water. The copper plate was blow dried and finished with a clean towel. I rolled a thin amount of ground across the plate’s surface just enough so that you could not see the copper sparkle through the ground. I drew on the plate near a window adding an element of sun and blowing air. The ground was really tacky. The newsprint was sticking to the plate after the first couple minutes of drawing. I drew for about 30 minutes but it proved to be very difficult. I used a sharp tipped pencil and a great deal of pressure to create the drawing. I left the plate out to air dry after which I placed it in the Ferric Chloride.
The plate was etched in a vertical etching tank filled with 35Â° Baume Ferric Chloride.
Timed Application of Mordant
20 Minutes/Rinse/10 Minutes/Rinse/15 Minutes/Rinse
Removal of Grounds
The ground was removed using a stripper bath of Arm & Hammer Washing Soda and water (100 grams/1 liter). I rinsed the plate under warm water after soaking it in the stripper bath for 10 minutes.
After Bath Evaluation
Like previous tests some marks have been translating while others are not visible at all.
The plate was inked with unmodified 50% Graphic Chemical Bone Black and 50% Graphic Chemical Stiff Black. The ink was carded on with a orange plastic scraper, wiped with used tarlatan, and hand wiped.
Paper Type: Hahnemule Copperplate
Paper Soaking Time: 15 Minutes
Press Blanket Setup: Small Takach, 2 Blankets, 8.0 pressure
I am seeing a weak line and not much in the way of tone in the proof.
