The second in a series of guest posts on Hidden Hazards in the Arts with our partner, the Local Hazardous Waste Management Program in King County (LHWMP)…
Bathtubs, Cyanide & that Beautiful Blue Tone
I was lucky in my undergrad experience. My program had an emphasis on experimental and traditional (like 1826) photography. I understood that digital photography was going to be the 21st century medium, but I was drawn to hands on darkroom techniques.
Now I should point out that I studied at Montana State University. The school had acquired a Fine Art habit. Making art was “research” and we had access to all kinds of equipment and were encouraged to experiment. I have vague and blurry memories of safety lectures. Unfortunately, I couldn’t tell you one word about gloves, tongs, or ventilation. I do have notes on “maybe do outside” scribbled next to a few processes, which seems hilarious and ominous to me now.
In spring semester (which in Montana means snow covered and 20 below zero), I took an intermediate black and white photography course. The assignment was simple: work with a Hasselblad, process 2 or 3 rolls of film and three prints. I filled my rolls, made the prints, and still had time before they were due, so I decided to try something new – tone my prints blue! Toning makes photographs archival, so it was good practice.
I rush-ordered potassium ferricyanide blue toner from Photographer’s Formulary and got to work. It was a cold day and my car wasn’t starting so I decided to work in my bathroom with a safelight. The directions seemed simple. Blue was a direct toner and I didn’t need to bleach the print first or redevelop it, I just had to put the image into the solution and wait for the color I wanted. I went into the bathroom, closed the door, and turned on the overhead fan and safelight. The solution was easy to mix and I got to work.
Sitting with my head over the tub watching my final print I started to get bored, so I read over all the text on the formula packet. There it was: “Always work under proper ventilation. Do not heat mixture to over 65 degrees Fahrenheit to avoid off-gassing.”
Off-gassing? Isn’t this cyanide toner– does that mean cyanide gas?!
I ran from the bathroom. How warm was it in my house? Where did that little bathroom vent go? How long had I been in there? Where were my gloves? Where were my gloves?
Luckily, I was a poor college student too cheap to turn on the heat. My house was balmy 50 degrees. I opened every door and window – freezing, but ALIVE.
Ten years later, Photographers Formulary carries a different blue toner, but you can still get potassium ferricyanide somewhere. I’m not sure I was truly in danger of gassing myself, I’d need a chemist to tell me that….but since I don’t have chemists on speed dial, I’ll just skip the bathtub in favor of a properly ventilated lab space – one where I won’t pass out in a cloud of fumes or drown in a tub of toxic chemicals.
The photo did come out beautifully though, as you can see.
