Broad bobbin collar too fashionable?

While X-ray fluorescence (XRF) spectroscopy is a well-established technique for the investigation of paintings, the apparatus used are usually custom built and not widely available. Now, Matthias Alfeld and colleagues have developed a portable macro XRF spectrometer to look at paintings in situ.

The team used the device to look at a portrait by Govert Flinck, a Dutch painter who was a protégé of the great Rembrandt. Interestingly, they found that originally the subject was painted wearing a broad bobbin lace collar and long lace cuffs but this was toned down for the final version, possibly because it was too trendy.
