Experiment Title: Dead Bath Regeneration Test
Experiment Goal: To etch a 3-minute plate in the 6 oz depleted bath with the added 1/2 a tablespoon of copper sulfate. So we can compare this 3-minute plate with our other 3-minute plate tests.
Plate material: Aluminum (5052)
Plate Preparation: Steel wooled, degreased with Bon Ami and soy sauce, then backed with contact paper.
Evaluation of Plate Preparation: Normal
Etching Bath Notes: The bath was still its typical milky green color.
Time in bath: 3 minutes
After Bath Evaluation: The bath was still not very active during etching.
Removal of Grounds: N/A
Inking Methods: Bone black, 10% Burnt Plate Oil 00,
r Type: Hahnemule Copperplate
Soaking Time: 15 minutes
Press, blanket set up, pressure: Praga press, 2 blankets, 1/8, 1/8
Conclusions: The results of this 3-minute print seem consistent with our Citric Acid Degeneration Test #3. (4/26/2018) The plate printed fairly light, but still with some nice tone.
