Prof. Simeen Sattar: Artists’ Materials: Metals and Prints

I’m a physical chemist in the physics program with a long-standing personal interest in art history.  I’m teaching a new course this semester about the chemistry of photography.  Since the goal of the course is to understand the chemistry of light-sensitive materials, the first four weeks have stressed light and color, ionic and covalent compounds, and chemical reactions.   Alongside these topics, we’ve studied, and made, dichromate prints, cyanotypes, and diazo prints.  In contrast to conventional photography, none of these processes involve silver.

Diazo Prints

In the cyanotype process, a paper coated with a yellow light-sensitive solution is exposed to sunlight.  Within a few minutes, ultraviolet light induces the formation of an iron compound known as Prussian blue in exposed areas.  It’s quite magical.  The cyanotype process was invented by the renowned astronomer Sir John Herschel in the 1840s.  Prussian blue itself is part of another story.  Discovered in the early 1700s, it is the first modern artificial pigment and displaced ultramarine and cobalt blue from artists’ palettes.

We’re now moving on to the chemistry of silver-based photography using a wonderful book by Roger Bunting called The Chemistry of Photography.  The highlight of this week’s experiment is making a silver mirror.  Next week, we’ll make salted paper prints, the precursor to silver/emulsion photography.

After looking at Judy Pfaff’s exhibition in Chelsea, don’t miss Dan Flavin’s light pieces at Paula Cooper (534 W. 21), and Sue Williams’ mini-retrospective the at 303 Gallery (547 W. 21).  It omits some highlights from her career, but she is a fine painter.  As much as she tries to gross you out, she always brings along her painterly finesse.  And check out Bard Prof. An-My Lê’s luminous, large-scale photographs taken from the decks of battle ships by this world traveler, at the Murray Guy Gallery (453 W. 17).

You can see an earlier example of An-My’s work front and center at the critically praised The Original Copy:  Photography of Sculpture, 1839 to Today at MoMA (11 W. 53), a wide-ranging and original exhibition that also includes Bard Prof. Larry Fink.  The show is right next to MoMA’s Matisse, Radical Invention 1913-1917, a not-to-be missed survey of one of the modern master’s most daring artistic periods.
