Prints to the Getty Institute for XRF Analysis

The Getty Conservation Institute has kindly offered to perform XRF analysis of my five processes in which an image is "seeded" with a noble metal and subsequently developed out into a full image with silver nitrate. The purpose of the analysis is to determine how much of the image-forming metal in a given print is silver and how much is the nobler metal. Of interest to me is the serebrutype -- ruthenium and silver. In the 19th and early 20th centuries, ruthenium was occasionally used to tone silver prints. However, the old texts on Google Books reveal some controversy as to whether ruthenium actually displaced and/or coated silver or whether it merely stained the paper. The Getty's XRF analysis will settle a hundred year old, and long forgotten controversy.

Documentary Coming Later This Year

The last two weeks of 2014, I hosted in my squalid loft in Austin one Dr. Sichendra Bista. The long-suffering Dr. Bista endured 700 sq ft shared with an obsessive-compulsive (me), a cat, and a dog. Despite the adverse conditions, Dr. Bista, who was a contributor to the award-winning documentary "Creative Crosswords" (q.v. on vimeo.com) and who shot an independent documentary about a dwindling Nepalese tribe, shot two documentaries. One records all of my processes (Texas Chrystoype, Karytype, Fannintype, Palladium+, Electrumtype, Kytheratype, Serebrutype, Rhodiotype Kary, and Iridiotype Kary). Dr. Bista also shot an extended interview with me, with Ed Buffaloe of unblinkingeye.com repute, the ever-fascinating Spiffy Tumbleweed, and a rising Austin-based artist named Hector Hernandez. The theme isn't quite "the old made new" but it dances around it. But I commit the grievous error of second-guessing an editor... I'll update this note once a preview becomes available online. Meanwhile I'll be adding more videos to my page on youtube

TIP FOR PREPARING AMMONIUM FERRIC FERROUS OXALATE (OR SODIUM OR LITHIUM FERRIC FERROUS OXALATE)

After you dissolve 4 grams of ammonium ferric oxalate crystals in 8 ml of distilled water, top the solution off to 10 ml and pour it into a stoppered brown bottle. Add ascorbic acid solution (1% for gold or 2% for palladium and/or platinum) to the bottle of 10ml of 40% ammonium ferric oxalate (or of sodium or lithium ferric oxalate). As I describe repeatedly in my videos and online articles, remember that you have to shake the bottle vigorously -- for 15 to 30 seconds -- to disperse the ferrous iron subsequently created evenly throughout the solution. Otherwise, the ferrous iron will simply precipitate out of solution and fall to the bottom of the bottle: you likely won't get satisfactory results when you attempt to print with a solution of AFFO in that state.
