How to Spot a Fake Jackson Pollock Painting

posted by Jason Kottke   Dec 07, 2018

Forensic scientist Thiago Piwowarczyk and art historian Jeffrey Taylor are often called upon to authenticate purported paintings by well-known artists. Using a drip painting resembling Jackson Pollock’s work, they show how they use historical research, hardcore science, and good-ol’ human observation. The steps they go through are:

1. Provenance research. Is there any documentation of the artist painting this? Who owned it and when? Forged documentation can be an issue here.

2. Visual analysis. Does the material used for the painting fit the artist and the timeframe? Often, a forger won’t sign a fake to mitigate any potential legal ramifications.

3. Photography and ultraviolet analysis. Was the canvas reused? Is there an under-painting or drawing?

4. X-ray fluorescence spectroscopy. What elements are present in the paint? Do they match those in the paints normally used by the artist?

5. Microscopy & Raman spectroscopy. What kind of paint was used? Did that paint exist when the artist was working?

Super interesting. All of the craft aside, Piwowarczyk also says that “if the deal is too good, there’s something wrong”. $25,000 for a Pollack? Nope. (via open culture)
