No archival issues. Oil paint on acid free paper has been used without sizing or isolation for hundreds of years. My monotypes are made with etching and litho inks on printmaking paper, so the initial layer is oil based anyway. I simply come back later with oil paint over that. I find the idea of worrying about whether my work will last 1000 years to be absurd.
ya, i guess so, I'm just afraid of them not lasting even one year, happened to a friend of mine who was diluting the ink with corn oil and it yellowed the paper. do you know which type of oil would be best to use or what to avoid? do you have an opinion on alkyd mediums? sorry for all the questions
If you're using ink, use etching inks thinned with turpentine or kerosene. Do not use products like corn oil or vegetable oil, or any oil medium for that matter. You may use oil paints as well- I do- again thinned with turpentine. As to Alkyd, that should be fine as a medium.
