Résumé
We would like to comment this study recently published in JFS. It is a short technical note proposing an artificial aging technique for the dating of ballpoint pen inks. This is a very difficult and controversial topic, and we are worried about the nature of this paper. The authors propose several ideas to differentiate fast aging and slow aging inks, but their experimental data is not validly represented and/or discussed. The data is insufficient to draw any conclusions about any potential of the method for ink dating purposes. This lack of information on the subject must be filled before proposing such methods for practical caseworks. These are preliminary and unconvincing results from development research performed in a laboratory on controlled samples without due warnings about potential shortcomings. They cannot be used or even compared to results obtained in real situations on uncontrolled specimens of limited size, unknown composition and undefined storage conditions. This can leave an undeserved feeling that these methods are ready for implementation when the task of ensuring their scientific validity is still far away.
