I am working on a project to find the best solvent for seperating out the elements of purple, red, and green markers. I put the colors on the bottom of filters and dip them in a solvent. I am using coffee filters. Will it make a difference if I use the brown unbleached filters or bleached filters?

Dear Anon,
Not meaning to be a wiseguy, but maybe that could be part of the experiment also, the effect of the paper. Otherwise I don't think there will be much difference, except you might not be able to see some of the very faint spots on the colored paper.

Regards,
Mark
