Have any of the members of this list ever compared the various ink manufacturers' products using paper chromatography? This involves putting a premeasured drop of ink on the end of a absorbent paper strip and putting that end in a solvent (in this case, probably water or alcohol). The colors in the ink migrate through the paper, separating on the way to the other end. http://wwwchem.csustan.edu/chem1002/mrsketch.htm offers a simple method.
